I.
Plaintiff-appellant Davis Oil Company appeals from the judgment of the district court holding that the Due Process Clause of the fourteenth amendment does not require that a foreclosing mortgagee provide actual notice to a mineral lessee whose lease will, under Louisiana law, be extinguished by the seizure and sale of the subject property.
For the reasons set forth below, we affirm the judgment of the district court.
A. Facts
The underlying facts of this case are largely undisputed and were found by the district court as follows.
In August of 1977, Kenneth Upton (“Upton”) purchased a 16.43 acre tract of land (the “tract”) located in Lafayette Parish, Louisiana. In May of 1983, Upton mortgaged the property as collateral for a $600,000 loan from defendant First National Bank of Lafayette (“FNB”). The collateral mortgage was properly recorded in the mortgage records of Lafayette Parish. The loan was intended to finance Upton’s business, American Tools, Inc.
In November, 1983, Upton granted a mineral lease on the tract to Louisiana Land Management, Inc. (“LLM”). The lease was promptly recorded in the Lafayette Parish conveyance records. On January 30, 1984, LLM assigned the lease to plaintiff Davis Oil Company (“Davis”). This assignment was also promptly recorded.
Upton then defaulted on the loan and on other obligations to FNB in April, 1984. FNB filed suit against Upton and American Tools, Inc., alleging default on the mortgage encumbering the tract. Upton confessed judgment and waived all delays. The judgment reflected a total debt of $3,500,000 and recognized the mortgage affecting the property.
In execution of its judgment, FNB obtained a writ of fieri facias, ordering the Lafayette Parish Sheriff to seize property belonging to Upton. FNB targeted certain properties, including the land leased to Davis, for seizure and judicial sale. FNB was unaware of the mineral lease on the tract. On May 30, 1984, the Sheriff sold the land to FNB after obtaining a certificate of nonmortgage. A deed reflecting the sale was recorded in June, 1984. No *776 actual notice was afforded Davis although the judicial sale was advertised in compliance with article 2331 of the Louisiana Code of Civil Procedure.
On March 10, 1984, a Davis Oil Company well located on property adjacent to the subject tract “blew out,” indicating a significant hydrocarbon discovery. In August, 1984, Davis assigned portions of its interest in the lease to Exxon Corporation, Grace Petroleum Corporation, NWT Natural Resources Company, Saturn Energy Company, and Allen E. Paulson (these various assignees will be included in references to “Davis”). These assignments were recorded in November, 1984.
In September, 1984, Davis gave notice that it planned to apply to the Commissioner of Conservation for the establishment of a production unit for Bayou Tortue Well No. 4, incorporating the subject tract. Because defendant William P. Mills III (“Mills”) owned nearby property, he was provided with notice of this intent.
On October 31, 1984, Mills and FNB entered into a letter agreement in which FNB agreed to sell the subject tract to Mills. Negotiations continued over the warranty that FNB would deliver. In the interim, Mills obtained a title opinion which specifically questioned the validity of the sheriff’s sale on the ground that the mineral lessee may not have received notice of the foreclosure.
On February 4, 1984, the Commissioner of Conservation signed an order incorporating a portion of the subject tract into the Bayou Tortue Well No. 4 production unit. This act guaranteed the subject tract a share in the production from the unit. On February 12, 1985, Mills, John L. Robertson, Brenda Sue Harmon Robertson, Orel Bridges, Jr., and Ethel Sue Hoffpauir Bridges (collectively included in references to “Mills”) purchased the subject tract. The contract stipulated that the sale was subject to recorded leases. The sale was recorded the following day.
Davis filed suit in the Federal District Court for the Western District of Louisiana on July 1, 1985. Jurisdiction was based on the presence of a civil rights claim, 28 U.S.C. § 1343(a)(3) and diversity of citizenship, 28 U.S.C. § 1332. Davis sought a declaratory judgment that the sheriffs sale of the subject tract was invalid because Davis had not been provided with direct notice of the seizure and impending sale, in violation of the Due Process Clause. Second, Davis sought equitable relief for the increased value of the subject tract resulting from a well Davis had drilled on land adjacent to the tract and within the same production unit. Third, Davis sought a declaratory judgment that its lease could not, as a matter of Louisiana state law, be extinguished by a judicial sale enforcing FNB’s judgment. Finally, Davis asked for a declaratory judgment that the subject tract, again as a matter of Louisiana state law, was burdened by the lease because Davis recorded its lease prior to the sale of the property to Mills and the contract between Mills and FNB provides that the tract is subject to prior recorded leases, thereby estopping Mills from asserting otherwise. 1
B. The District Court Opinion
The district court, after a trial on the briefs and documentary evidence, denied relief to Davis on all counts. First, the district court held that although the sheriff’s sale constituted state action, and although the lease was a protected property interest, deprivation of which is subject to the constraints of the Due Process Clause, constructive notice was reasonable in this case. Second, the district court found that Davis was not entitled to equitable relief for any enhancement in the value of the subject tract because Davis had a statutory *777 remedy under section 30:5(C)(3) of the Louisiana Revised Statutes. Third, the district court found that as a matter of Louisiana law, Davis’ lease was extinguished by the sale because the consent judgment obtained against Upton was properly considered a foreclosure by ordinary proceeding which extinguishes all subordinate obligations such as Davis’ lease which was subsequent in time to the mortgage. Finally, the district court held that no concept of estoppel applied to prevent Mills from claiming that the subject tract was not burdened by the lease.
Davis filed a timely notice of appeal from the district court’s judgment.
C. Claims on Appeal
Davis argues on appeal that the district court erred in concluding that constructive notice of the seizure and sale of the subject property satisfied the requirements of due process. 2 Davis contends that its identity was easily and readily ascertainable from the conveyance records of Lafayette Parish and that absent an effort to provide Davis with actual notice of the sheriff’s sale of the subject tract, the sale was constitutionally flawed at least insofar as it extinguished Davis' interest in the subject tract. Mills and FNB advance three arguments on appeal. First, they argue that the foreclosure did not constitute action under col- or of state law. Second, they contend that even if there was state action, Davis was not “deprived” of a legally protected property interest because its lease was subordinate to the mortgage — thus, the property interest was simply extinguished by operation of a legal condition. Finally, they assert that even if Davis was deprived of a legally protected property interest, constructive notice was sufficient to satisfy the requirements of due process because Davis failed to avail itself of Louisiana’s “request notice” provision, La.Rev.Stat. Ann. 13:3886 (West Supp.1988).
This case therefore presents three issues on appeal: first, whether the district court erred in finding state action, second, whether the district court erred in finding that Davis was deprived of a legally protected property interest and third, whether constructive notice satisfied the Due Process Clause. We address these issues in turn.
D. Standard of Review
This action was submitted to the district court for trial on briefs and documentary evidence. The district court’s findings of fact, although based solely on documentary evidence, are subject to the clearly erroneous standard of review. Fed.R.Civ.P. 52(a) & advisory committee’s note (1985). Accordingly, we may not reverse the district court’s factfindings unless we are left, after reviewing the entire evidence, “with the definite and firm conviction that a mistake has been committed.”
Anderson v. Bessemer City,
II.
As a preliminary matter, it is useful to review the salient features of the Louisiana procedures that are at issue in this case. 3
Louisiana law provides two means of enforcing a mortgage. La.Code Civ.P. art. 3721 (West 1961 & Supp.1988). When a mortgage contains a confession of judgment, a mortgagee may foreclose on the mortgage through executory process which is an action in rem. Id. art. 2631. The mortgagee must file a petition to enforce *778 the mortgage, requesting the seizure and sale of the subject property. Id. art. 2634. The judge reviews the petition and supporting documents, id. arts. 2635-37, and orders the issuance of a writ of seizure and sale, commanding the sheriff to seize and sell the property affected by the mortgage. Id. art. 2638. The statutory scheme for executory proceedings includes no express requirements of actual notice, 4 except that the debtor is entitled to written notice of the seizure of the subject property — after the judgment has been rendered. Id. art. 2721. The only other notice required is the advertisement of the sheriff’s sale. Id. art. 2722.
If the original mortgagor has sold the property to a third party, the mortgagee may nevertheless enforce the mortgage, by executory process, directly against the property, without regard to the alienation of the property to a third party.
5
Id.
art. 2701 (creating a statutory
pact de non alienando
for all mortgages containing a confession of judgment). In the case of executory proceedings, there is no statutory requirement that the present owner receive notice of the seizure.
Id.
art. 2721;
but see Bonner v. B-W Utilities,
Alternatively, if the mortgage does not contain a confession of judgment, the mortgagee must first obtain a money judgment against the mortgagor. Thus, an ordinary proceeding differs from an executory proceeding in that the mortgagor must be made a party to the action and must therefore receive notice of the foreclosure proceeding itself. La.Code Civ.P. art. 1201 (West 1984 & Supp.1988). The judgment is then executed by a writ of fieri facias under which the sheriff of the parish will seize and sell the mortgagor’s property to satisfy the judgment. Id. art. 2291. A mortgagee may enforce a judgment obtained by ordinary process without reference to any alienation or transfer of the property, id. art. 3741 (also creating statutory pact de non alienando), but both the original mortgagor and the present owner of the property are entitled to notice of the seizure. 6 Id. art. 3742. The only other notice expressly required by statute is again the advertisement of the sheriff’s sale. Id. art. 2331 (notice of sale of property under writ of fieri facias).
The effect of a sale pursuant to foreclosure by either method 7 is to extinguish all inferior encumbrances upon the property. 8 Id. art. 2376. The property is sold, however, subject to any real charge or lease superior to the mortgage of the seizing creditor. Id. art. 2372.
Finally, an additional feature of the Louisiana scheme is the so-called request-notice provision contained in Revised Statute *779 13:3886. La.Rev.Stat.Ann. 13:3886 (West Supp.1988). Under RS 13:3886, any person may obtain notice by mail of the seizure of immovable property by paying a ten dollar fee and placing his or her name and address on file in the mortgage records of the Parish where the property is located. One question before us in this case is the extent to which RS 13:3886 cures any constitutional defects in Louisiana’s constructive notice provisions.
We proceed now to the issues presented on appeal.
A. Color of State Law
FNB maintains that the district court erred in finding that FNB, a private party, acted under color of state law in foreclosing on Upton’s property and in executing its judgment.
To state a cause of action under 42 U.S. C. § 1983, a plaintiff must allege first, that he or she has been deprived of a right “secured by the Constitution and laws” of the United States, and second, that the deprivation was by a person acting “under color of any statute, ordinance, regulation, custom, or usage, of any State....”
Adickes v. S.H. Kress & Co.,
For a party to be subject to suit under section 1983, the asserted deprivation of rights must stem from conduct fairly attributable to the state.
Lugar v. Edmondson Oil Co.,
The actions of a private party may therefore be attributed to the state only if two conditions are met:
First, the deprivation must be caused by the exercise of some right or privilege created by the State or by a rule of conduct imposed by the State or by a person for whom the State is responsible.... Second, the party charged with the deprivation must be a person who may fairly be said to be a state actor.
Lugar,
Although a myriad of tests have been applied to determine whether a party acts under color of state law, we think that Davis’ claims are sufficiently analogous to the prejudgment attachment cases to fall under the “joint participation” test applied in
Lugar.
9
See Lugar,
The plaintiff in
Lugar
alleged that he had been deprived of his property without due process of law when a private creditor sought and obtained prejudgment attachment of his property pursuant to a Virginia statute. The writ of attachment had been executed by the County Sheriff. The Court concluded that insofar as the plaintiff alleged only that his creditor had invoked the attachment statute without sufficient grounds to do so, he did not state a cause of action under section 1983. To the extent, however, that the plaintiff challenged the attachment procedure as defective under the fourteenth amendment, the
*780
Court found that he did state a valid cause of action.
Id.
at 940-41,
The Court reasoned that “[w]hile private misuse of a state statute does not describe conduct that can be attributed to the State, the procedural scheme created by the statute obviously is the product of state action.”
Id.
at 941,
To the extent that
Lugar
adopts a low threshold to establish joint participation between a private party and the state, its holding has been confined to the context of ex parte prejudgment proceedings.
10
Lu-gar,
In claiming that FNB did not act under color of state law, defendants rely primarily on
Earnest v. Lowentritt,
in which we held that the “[initiation of foreclosure proceedings pursuant to a mortgage implicates no ... authority of state law.”
In Earnest, we distinguished the mortgage foreclosure at issue from the pre-ad-judicative seizures discussed in Lugar and noted that the execution order permitting the sheriff to sell the Earnest property was obtained after the debtor had been given notice of the impending seizure and an opportunity to be heard on the merits of the seizure. Because the proceeding at issue in Earnest could not be characterized as ex parte, the mere invocation of state procedures by a private party was not sufficient to establish state action. Id. at 1201-02. We cautioned that a contrary holding would “transform every foreclosure action between private parties into state action of constitutional dimension.” Id. at 1202.
This case, however, does not present the same issue. In arguing that Earnest is controlling here, defendants fail to recognize that it is Upton, rather than Davis, who stands in the shoes of the Earnest plaintiffs. Although the foreclosure was not ex parte with respect to Upton (who received notice and did not contest the foreclosure), the gravaman of Davis’ complaint is that the Louisiana procedure allows foreclosure and the execution of a judgment pursuant to foreclosure without providing constitutionally adequate notice to other parties whose interests in the property will be extinguished along with the *781 debtor’s by the seizure and sale of the property. Thus, as the district court noted, Davis’ claim is precisely that the procedure is ex parte with respect to parties in its position.
We agree with the district court that insofar as Davis challenges the constitutionality of the Louisiana procedure on these grounds, FNB may be considered a “joint participant” with the state because it set into motion the procedures that would extinguish Davis’ interest in the subject property.
11
See Folsom Investment Co. v. Moore,
*782 B. Protected Property Interest
Although the defendants do not dispute that a mineral lease is a legally protected property right under Louisiana law, 13 they argue on appeal that Davis was not “deprived” of that right within the meaning of the Due Process Clause of the fourteenth amendment.
Defendants rely on the axiom that property interests “are not created by the Constitution. Rather, they are created and their dimensions are defined by existing rules or understandings that stem from an independent source such as state law.”
Board of Regents v. Roth,
In support of this argument, defendants rely primarily on
FDIC v. Morrison
-an Eleventh Circuit case in which the court held that although a mortgagor’s equity of redemption is a legally protected property right, “[foreclosure within the contractual terms and the requirements of Alabama law did not deprive [the mortgagor] of his equity of redemption, but only terminated it.”
Similarly, defendants argue, Louisiana law ranks property interests chronologically, according to the date that an interest is recorded and provides clearly that subordinate property interests will be canceled by a superior creditor’s foreclosure on the property.
See supra
(summary of Louisiana foreclosure procedure). Furthermore, “[a]ll persons are held to have constructive notice of the existence and contents of recorded instruments affecting immovable property.”
Judice-Henry-May Agcy. Inc. v. Franklin,
The Eleventh Circuit’s reasoning in Morrison illustrates the persistent difficulty of defining the rights in property that are *783 subject to constitutional protections. 14 Although the Supreme Court has recognized that the states have broad power to create and define the scope of property rights, the Court has also recognized that a purely positivist view of property rights threatens to render the Due Process Clause meaningless.
Three justices pressed the positivist notion of state-created property rights to its logical limits in
Arnett v. Kennedy,
arguing that “where the grant of a substantive right is inextricably interwined with the limitations on the procedures which are to be employed in determining that right, a litigant in the position of appellee must take the bitter with the sweet.”
The “bitter with the sweet” approach was resoundingly rejected, however, by a majority of the court in subsequent cases:
[I]t is settled that the “bitter with the sweet” approach misconceives the constitutional guarantee.... The point is straightforward: the Due Process Clause provides that certain substantive rights —life, liberty, and property — cannot be deprived except pursuant to constitutionally adequate procedures. The categories of substance and procedure are distinct. Were the rule otherwise, the Clause would be reduced to a mere tautology. “Property” cannot be defined by the procedures provided for its deprivation any more than can life or liberty. The right to due process “is conferred, not by legislative grace, but by constitutional guarantee. While the legislature may elect not to confer a property interest ..., it may not constitutionally authorize the deprivation of such an interest, once conferred, without appropriate procedural safeguards.”
Cleveland Board of Educ. v. Loudermill,
Although the Eleventh Circuit in
Morrison
attempted to avoid the trap of
Arnett
by characterizing the limitation at issue as substantive rather than procedural,
*784 The simple act of labeling a condition “substantive” does not eliminate due process concerns. At some point, to hold that no due process attaches to the operation of a “substantive” condition that terminates a property right is to define the scope of that property right by the absence of procedural protections attendant upon its termination. This too reduces the due process clause to a tautology.
Moreover, to apply the Eleventh Circuit’s reasoning to this case would extend
Morn-son
far beyond its original context. The court emphasized in
Morrison
that “[t]he blame for turning the once-hypothetical foreclosure into reality lies solely with the mortgagor.”
The Supreme Court has not allowed the State’s power to impose conditions on property rights to encroach this far on the protections afforded by the Due Process Clause. Rather, the circumstances in which the termination of a property interest by operation of a legal condition does not trigger due process concerns are limited.
In
Texaco Inc. v. Short,
for example, the Court upheld an Indiana statute which provided that a severed mineral interest which was unused for a period of 20 years would lapse and revert to the surface owner, unless the mineral owner filed a statement of claim in the county recorder’s office.
The Supreme Court has recently made clear, however, that the seductively simple reasoning of Short may not be broadly applied to erode due process rights.
In
Tulsa Professional Collection Services v. Pope,
the Court distinguished
Short
from a case involving a provision of Oklahoma’s probate laws which required that claims “arising upon a contract” be presented to the executor of a decedent’s estate within two months of the publication of a notice advising creditors of the commencement of probate proceedings.
The Supreme Court reversed the Oklahoma court, holding that because the Oklahoma nonclaim statute was set into motion by probate proceedings, it could not properly be considered “self-executing.”
Id.
Although the time limit on the creditor’s claim in Pope could probably not be considered a part of the substantive definition of that property interest, Pope indicates that the crucial factor in determining whether due process applies to the termination of a property interest is not whether the condition is labeled substantive or procedural, but the means by which the condition is set into motion. Even if a property interest is subject to a “substantive” condition from its inception, the operation of that condition may still constitute a deprivation of property to which due process attaches if the “condition” is not self-executing.
*786
The self-executing statute at issue in
Short
did not implicate due process concerns precisely because the statute itself clearly delineated various conditions with which a mineral owner had to comply in order to maintain his or her property rights and also specified that failure to comply with those conditions would result in the termination of those interests.
Short,
Pope
also makes clear that a property interest may be “adversely affected” by a legal proceeding, thus triggering due process concerns, even if the proceedings at issue will not “adjudicate the merits” of the asserted property interest: “[I]t is irrelevant that the notice seeks only to advise creditors that they may become parties rather than that they are parties, for if they do not participate in the probate proceedings, the nonclaim statute terminates their property interests.”
It is therefore immaterial that Davis’ mineral lease was not itself the object of the foreclosure. 19 It is enough that Davis’ *787 property interest, along with the mortgagor’s, would be extinguished by the foreclosure.
We therefore hold that the termination of Davis’ lease by FNB’s foreclosure and the subsequent seizure and sale of the subject property “deprived” Davis of a legally protected property interest within the meaning of the fourteenth amendment.
C. Constitutionally Adequate Notice
Having held that the foreclosure was subject to the constraints of the Due Process Clause because Davis was deprived of a legally protected properly interest by action under color of state law, we must now decide whether the requirements of due process were satisfied by advertising the sale of the subject property in a local newspaper.
Invoking the broad language of
Mennonite Board of Missions v. Adams,
Davis asserts that its identity and address were readily ascertainable from the conveyance records of Lafayette Parish and that it was therefore entitled to actual notice of the seizure and sale of the subject property.
The district court, however, found that information regarding Davis' interest in the subject property was not reasonably available to FNB as a seizing creditor. The district court held that “[ajbsent knowledge of the existence of a mineral lease, FNB was not constitutionally required to blindly search conveyance records for those interests.” 20 The district court noted further that although Davis’ failure to request notice under Louisiana Revised Statutes 13:3886 did not constitute a waiver of its due process rights, the existence of the request-notice statute should be a factor in determining the overall reasonableness of requiring a creditor to provide actual notice to parties with interests in the subject property. The district court held that RS 13:3886 was curative of any constitutional deficiency in Louisiana’s constructive notice provisions only with respect to parties whose interests in the property are not otherwise reasonably ascertainable.
We note as an initial matter that the district court was absolutely correct in holding that a failure to request notice under RS 13:3886 does not constitute a waiver of due process rights. Although due process rights may be waived, a waiver of constitutional rights is not effective unless the right is intentionally and knowingly relinquished.
21
Bueno v. City of Don
*788
na,
As the district court correctly held in this case, a seizing creditor who avails itself of state foreclosure procedures is constitutionally obligated to provide “notice reasonably calculated, under all circumstances, to apprise interested parties of the pendency of the action.”
Mullane v. Central Hanover Bank & Trust Co.,
We also agree with the district court, however, that the existence of RS 13:3886 is not wholly irrelevant to the determination of the reasonableness of constructive notice under particular circumstances.
Although the three justices who dissented in
Mennonite
expressed concern that the majority had abandoned the “reasonableness” inquiry of
Mullane
in favor of a rigid rule that constructive notice is never constitutionally adequate,
Applying the principles of Mullane and Mennonite, the district court concluded below that a search of the conveyance records to identify parties with mineral leases on the subject property would be unduly burdensome.
We note that to the extent that the district court opinion characterizes the burden imposed on a seizing creditor as requiring the creditor to identify
viable
mineral leases, the district court may not have framed its inquiry properly. The seizing creditor is not required to determine conclusively which property interests are in fact viable. Rather, the creditor is required only to undertake “reasonably diligent efforts” to identify and provide notice to parties having an interest in the subject property.
Pope,
Applying this standard, we nevertheless conclude that the record amply supports the district court’s finding that a search of the conveyance records to identify parties with mineral interests would be unduly burdensome and “is a task beyond the routine examination of land records that was involved in
Mennonite.” See Bender,
In asserting that the district court’s conclusion is erroneous as a matter of fact, Davis relies heavily on the deposition of Joan Broussard, an employee of the Lafayette Parish Clerk’s office. While Ms. Broussard testified that she was able to identify Davis’ lease and to make copies of the relevant documents within 24 minutes, the deposition also reveals that in order to identify Davis’ lease, Ms. Broussard had to run a separate check to determine that the original lease to Louisiana Land Management had been assigned to Davis. Davis has established at most that it would be fairly easy to identify a single lessee-when the Clerk knows what to look for. This does not answer the question whether “reasonable diligence” would in general require a seizing creditor to search the Parish conveyance records. If a piece of property is subject to multiple leases, or if the interest in a single lease has been divided and assigned to different entities (as it in fact was in this case), the search for those with an interest in the property would require far more than an initial search of the conveyance records in the name of the owner of the subject property. The creditor would have to trace in turn the conveyance records of each subsequent assignee. Far from being a simple, 24 minute undertaking, a search of the conveyance records for the mineral interests on a single piece of property could resemble a rather large tree with several limbs and innumerable branches. Thus, even if the creditor makes no attempt to determine the actual validity of a particular lease, the process of merely identifying those who might have an interest in a mineral lease could itself be extremely cumbersome. We conclude that the district court did not, therefore, overstate the burden to creditors of conducting this type of search.
In evaluating whether it is reasonable, under the circumstances, to require a seizing creditor to undertake a search of the conveyance records, we find the Second Circuit’s reasoning in
Bender v. City of Rochester,
on which the district court also relied, to be persuasive. In
Bender,
the court considered whether due process required that the city search the records of the Surrogate’s Court to determine whether the owner of property subject to a tax foreclosure had died and to identify the distributees of the subject property. The court noted that a search of the records of the Surrogate’s Court would not necessarily reveal either the identity of the decedent’s successors in interest or the nature of their interests.
The court thus evaluated the burden of conducting a potentially fruitless search, together with the means available to the claimant to protect his asserted interest, and concluded that “[i]n light of all the pertinent circumstances,” the names of dis-tributees were not “reasonably ascertain *790 able” within the meaning of Mennonite. Id. at 12.
In the instant case, we evaluate the burden of requiring a seizing creditor to wend its way through a potentially complex maze of leases and assignments in order to identify interested parties, together with the relatively simply means available, under RS 13:3886, to ensure receipt of notice. 23 We conclude that under the circumstances “reasonable diligence” did not require that FNB search the conveyance records to ascertain the identities of mineral lessees. 24
We are aware, as was the Second Circuit, that
Mennonite
states explicitly that “a party’s ability to take steps to safeguard its interests does not relieve the State of its constitutional obligation.”
Specifically, we do not construe
Mennonite
as requiring actual notice to every party who has a publicly recorded interest in the subject property.
But see Verba v. Ohio Casualty Ins. Co.,
Mills argues vehemently that Davis should not be heard to complain of the foreclosure because parties in the oil and gas industry are well aware that a mineral lease may be extinguished by foreclosure on a superior mortgage. Mills notes that it is common practice to obtain a subordination of a superior mortgage in order to protect a mineral lease from precisely the eventuality complained of here. While Davis’ failure to obtain a subordination in no way eliminates Davis’ due process rights, this factor does indicate that it is *791 not unreasonable to expect that a party in Davis’ position, having elected not to obtain a subordination, would at least take the minimal step of requesting notice under RS 13:3886 — which would have ensured that in the event of a foreclosure Davis would have an opportunity to preserve its interest by bidding at the sheriff’s sale.
The act of requesting notice under the statute does not, moreover, impose a burden of constant vigilence on the property owner. Rather, it allows one whose identity as an interest holder may not otherwise be readily ascertainable to protect his or her interest in the subject property through a single, simple act. We therefore do not believe that our limited reliance on RS 13:3886 runs afoul of Mennonite. 25
We therefore conclude that the district court correctly held that under the circumstances, constructive notice of the seizure and sale of the subject property was sufficient to satisfy the requirements of due process. 26
III.
For the reasons set forth above, the judgment of the district court is AFFIRMED.
Notes
. Mills filed a petition in Louisiana state court on January 10, 1986, seeking cancellation of Davis’ lease and damages for the defendants’ alleged failure to pay Mills a share in the production from the unit that includes the disputed parcel of land. Mills’ suit was removed to federal court on grounds of diversity of citizenship and was consolidated with Davis’ lawsuit against Mills and FNB. The district court held that Mills’ petition to cancel the lease was rendered moot by the court’s decision that the Sheriffs sale was constitutionally sound and had extinguished Davis’ lease on the subject tract of land.
. Davis does not challenge on appeal any of the district court’s state law holdings. Although Davis does maintain that its lease was not extinguished by the Sheriffs sale, its argument on appeal is based solely on the Due Process Clause and not on Louisiana state law. Our opinion therefore addresses only the constitutional issues.
. For a more detailed description of Louisiana’s procedures, see Rubin & Carter, Notice of Seizure in Mortgage Foreclosures and Tax Sale Proceedings: The Ramifications of Mennonite, 48 La.L.Rev. 535, 541-44 (1988).
. The sheriff is required to issue a demand for payment three days before the writ of seizure and sale is issued, but the mortgagor may waive the right to receive the demand for payment. La.Code Civ.P. arts. 2639-40.
. Such third parties do, however, have a statutory right to enjoin the sale and to retire the indebtedness. La.Code Civ.P. arts. 2702-03 (rights, respectively, of those who buy property subject to a mortgage (without assuming the debt) and those who purchase the property and assume the debt); see also infra note 6.
. Third parties claiming ownership are, like the judgment debtor, entitled to enjoin the sale of the property on specified grounds. La.Code Civ.P. art. 2298 (West Supp.1988). In an ordinary proceeding, third persons asserting a mortgage or privilege — whether superior or inferior to that of the seizing creditor — may also intervene at any time prior to the sale and seek to enjoin the sale until their claims are adjudicated. Id. art. 1092 (West 1984). When a judgment obtained under either ordinary or exec-utory process is sought to be enforced against a third party in possession of the property, the third possessor is authorized by statute to arrest the seizure (on specified grounds) and to retire the balance of the indebtedness. Id. art. 3743 (West 1961) (containing cross reference to article 2703).
. Article 2724 provides that a sale of property under a writ of seizure and sale issued in an executory proceeding is governed by the same provisions which apply to a sale under a writ of fieri facias.
. Inferior creditors are to be paid out of the sale proceeds, after costs are deducted, and the seizing creditor has been paid. La.Code Civ.P. arts. 2373, 2377 (West 1961).
. The prejudgment attachment cases are obviously not apposite insofar as Davis was not a debtor of FNB. These cases are analogous, however, insofar as Davis’ central contention is that the Louisiana procedure provides for the termination of all subordinate interests in the subject property, without requiring constitutionally adequate notice to the holders of such interests. As we discuss more fully below, any distinction between Davis’ claims and those of a debtor subject to a prejudgment attachment statute turns not on the nature of the underlying constitutional claim, but on the nature of the property interest at stake.
.
We recently noted, however, that in
Pennzoil v. Texaco,
Justices Brennan, Marshall and Blackmun all agreed with the portion of Justice Stevens’ concurring opinion that would have found state action.

. A holding to the contrary would require us to ignore the nature of Davis' constitutional claim. If we were to hold that FNB did not act under color of state law with respect to Davis, we would effectively hold that the only person who may maintain a section 1983 suit challenging the constitutionality of a private creditor’s seizure or sale of property is the debtor — when the plaintiffs complaint is precisely that the state may not permit the termination of other interests in the disputed property without requiring adequate notice to those interest holders. This question is more properly addressed by considering whether Davis in fact had a property interest protected by the fourteenth amendment, rather than subsuming the question in the state action inquiry.
. The Court cautioned in
Lugar
that "under color of any statute” should not be read "in such a way as to impose a limit on those Fourteenth Amendment violations that may be redressed by the § 1983 cause of action.”
On the other hand, the Court noted that "[i]f action under color of state law means nothing more than that the individual act ‘with the knowledge of and pursuant to that statute,’ ... then clearly under
Flagg Brothers
that would not, in itself, satisfy the state-action requirement of the Fourteenth Amendment."

In

the Court found that the private defendants did not act under color of state law in threatening to sell the plaintiffs’ property pursuant to U.C.C. § 7-210.

itself, however, distinguished the Court’s earlier prejudgment attachment cases.

For the reasons set forth in the text, we do not believe that this holding is inconsistent with cases that have not found state action in nonjudicial foreclosures by private parties.
See Barrera v. Security Building & Investment Corp.,
*782 Because we read Davis’ claim to be essentially analogous to the Court’s prejudgment attachment cases, we do not need to reach the question of when action "under color of state law" would not also be state action for fourteenth amendment purposes. Both elements are present here.
. Under Louisiana law, mineral rights are “real” rights and the owner "may assert, protect, and defend his right in the same manner as the ownership or possession of other immovable property." La.Code Civ.P. art. 3664 (West Supp. 1988); see also La.Rev.Stat.Ann. § 31:16 (West 1989).

In
Webb’s Fabulous Pharmacies, Inc. v. Beckwith,
the Supreme Court invalidated as an unconstitutional taking a Florida statute which authorized the county clerk to invest moneys deposited with the registry of the court in interest-bearing accounts and provided that all interest accruing from such deposits would be deemed the property of the office of the clerk of the court.
The Court noted that the principal deposited in the registry “plainly was private property,” and emphasized that ”[t]he usual and general rule” is that interest follows the principal.

. Two commentators discussing the implications of Mennonite for Louisiana’s mortgage foreclosure scheme advance an argument similar to defendants’ argument. They note that a tax sale — the procedure at issue in Mennonite — is different from ordinary foreclosure proceedings precisely because it does upset the state-defined ranking of property interests:
Mennonite addressed a taxing authority’s actions that caused erasure of otherwise superi- or liens and encumbrances — a situation that cannot arise in conventional foreclosures. One could contend that Mennonite’s holding is limited to situations where the state "bootstraps" itself into a superior ranking position. In that instance, absent notice, a mortgagee has no way of knowing when the security interest may be affected, because pre-loan precautions in obtaining a title opinion (or title insurance) and checking the mortgage records will not suffice to protect against subsequent tax sales. An inferior lien holder, on the other hand, can determine whether it will be primed by private party superior liens. Since property rights generally are created by state law, and state law can dictate which rights are given superior preference, one can argue that an inferior mortgagee in. effect "assumes the risk" that its mortgage not only may be primed but also may be extinguished by a foreclosing superior lienholder.
Rubin & Carter, supra note 3, at 549 (1988).
. In
United States v. Locke
the Court upheld an analogous provision of the Federal Land Policy and Management Act (“FLPMA”) which established a recording system for mining claims on federal lands and provided that claims would be deemed abandoned if the claimant failed to register the claim initially with the Bureau of Land Management or failed to file with state officials each year thereafter a notice of intention to hold the claim and an affidavit or report regarding work performed on the claim.
The Court also noted that "[i]n the exercise of its administrative discretion," BLM had for the past several years elected to mail annual reminders to claimants.
. The nature of the condition’s uncertainty is therefore different here than in
Morrison.
The court in
Morrison
stated that the fact that the "moment" of foreclosure was undetermined when the parties signed the mortgage “did not nullify the conditional nature of [the] equity of redemption."
Because the instant case may be distinguished from Morrison on this ground, we need not address further the possible effect of Pope on the validity of the Eleventh Circuit’s reasoning in Morrison.
. We note that Louisiana law does not appear to give lessees any specific, statutorily-defined rights with respect to foreclosure proceedings.
In contrast, third parties who have purchased the property "subject to" a mortgage (without assuming the debt) or who have purchased the property and “assumed” the debt' have statutorily-defined rights with respect to foreclosure proceedings and execution of a foreclosure judgment. See supra (summary of Louisiana foreclosure procedure).
It does not appear that a mineral lessee would be considered a third possessor under Louisiana law.
See In re Union Central Life Ins. Co.,
Similarly, parties claiming a mortgage or privilege on the property may intervene in a foreclosure by ordinary proceeding in order to ensure that their claims are included in the distribution of proceeds from the sheriffs sale. La.Code Civ.P. art. 1092. It is unclear whether a lessee would be entitled to intervene under this provision. It could therefore be argued that because a lessee’s statutory rights with respect to a foreclosure are more limited than those of other interest holders, a lessee's rights are even more conditional.
See Bonner,
However, even if the only benefit that a lessee would gain from receiving notice is the opportunity to bid at the sheriffs sale, that opportunity is not insignificant given that the lessee’s property interest would otherwise be terminated altogether by the sale. Accordingly, we do not *787 consider the limited nature of a lessee's rights sufficient grounds to alter our conclusion that Davis was "deprived” of a legally protected property interest within the meaning of the fourteenth amendment.
. Relying on depositions of FNB employees who stated that they were aware that there had been a "blow out” at a well located in land adjacent to the subject tract, Davis maintains that FNB had reason to know of the existence of a mineral lease and should have made appropriate inquiries. Davis does not, however, dispute the district court’s finding that FNB did not actually know of the existence of a lease. As we explain more fully below, we agree with the district court that absent knowledge of the existence of a lease, FNB was not required to search the conveyance records to identify mineral lessees.
. Although the Supreme Court has not held expressly that the standard for waiver of constitutional rights in non-criminal contexts is the same as in the criminal context, it has also declined to expressly adopt a lower standard.

To shift in this fashion the burden of compliance with the Due Process Clause almost entirely to the shoulders of individual property owners would eviscerate the protections afforded by the Constitution.
See Mennonite,
. Similarly, the district court opinion at times frames the relevant standard as whether the name and address of the party is "very easily ascertainable," citing
Schroeder v. City of New York,
. We note that RS 13:3886(D) which provides that "[t]he failure of the sheriff to notify a person requesting notice of seizure shall not affect the rights of the seizing creditor nor invalidate the sheriffs sale" may pose constitutional problems to the extent that RS 13:3886 is not wholly supplementary to the notice that is required by the Due Process Clause. That issue, however, is not properly before us in this case since Davis did not request notice under RS 13:3886.
. This holding is not inconsistent with
Bonner
and
Portis
which held, respectively, that a third possessor and a second mortgagee were entitled (with some qualifications in each case) to more than constructive notice of the seizure of property in a foreclosure by executory process.
Bonner,
Because the reasonableness of requiring a particular method of notice depends on the particular circumstances.
Pope,
Davis observes that a seizing creditor would already be required, under Bonner, to search the conveyance records to determine whether the subject property had been sold to a third party. First, without expressing an opinion on the matter, we note that the holding in Bonner is more limited than Davis states — the court relied heavily on the fact that the mortgagee in Bonner knew the name and address of the third possessor.
Second, and more importantly, as we note above, a search of the conveyance records does not consist of a single search, but would also involve tracing any subsequent transfers made by the persons to whom the original owner had sold or leased a property interest. It is therefore reasonable to draw some line limiting a seizing creditor’s obligation to search land and conveyance records.
Our holding today rests upon the particular complexity of identifying mineral interests through a search of Parish conveyance records and should not be construed to undermine the holdings in Bonner and Portis.
. The Supreme Court has held that a provision for requesting notice may save a notice procedure that is otherwise constitutionally suspect. In
Lehr
v.
Robertson,
. Our holding makes it unnecessary for us to address the propriety of the remedy sought by Davis.
