¶ 1 These consolidated appeals stem from three consolidated lawsuits concerning a construction dispute among a property owner, a tenant, a general contractor, and six subcontractors involved in improving restaurant space at a Paradise Valley, Arizona resort. Smoke Tree Resort, LLC (“Smoke Tree”), the owner of the property, appeals from superior court judgments awarding damages to six subcontractors on their claims for unjust enrichment. Subcontractors Wang Electric, Inc. (“Wang”), Aero Automatic Sprinkler Company (“Aero”), and Allied Acoustics, Inc. (“Allied”) cross-appeal from the superior court’s judgment invalidating their mechanic’s liens on Smoke Tree’s property and dismissing their lien foreclosure actions. Subcontractors Adobe Drywall, LLC and Adobe Paint, LLC (collectively “Adobe”) appeal from the court’s judgment invalidating their mechanic’s liens on the leasehold interest in the restaurant and dismissing their lien foreclosure actions. For the reasons that follow, we reverse and remand for further proceedings.
BACKGROUND
¶ 2 Smoke Tree entered a lease agreement in October 2007 with REM on Lincoln, LLC (“REM”) for rental of restaurant space at Smoke Tree’s resort property. The leasehold term was for ten years, and REM had the option to extend the term for an additional five years. The lease required REM to remodel the restaurant in accordance with plans approved by Smoke Tree. Although REM was charged with organizing the remodel, the lease required Smoke Tree to reimburse REM up to $840,000 in remodeling expenses. REM was required to pay all costs and expenses greater than $840,000.
¶ 3 In January 2008, REM hired K.A.I. Designs Inc. (“KAI”) to serve as general contractor on the restaurant remodel. Their
¶ 4 As the work progressed, the subcontractors submitted periodic invoices to KAI. KAI then submitted these payment applications for approval first to REM and then to Smoke Tree. Once Smoke Tree approved the invoices, Smoke Tree issued payments directly to KAI for disbursement to the subcontractors, despite the lease language calling only for reimbursement of REM’s costs. A declaration from David Aboud, the president of KAI, reflects Smoke Tree paid approximately $790,000 to KAI.
¶ 5 Near the end of April 2008, progress payments stopped. Wang, Aero, Beecroft, and Allied then filed mechanic’s liens on Smoke Tree’s property for the billed value of the work performed but not compensated (the “Uncompensated Work”). Adobe filed mechanic’s liens on REM’s leasehold interest in Smoke Tree’s property for the billed value of Adobe’s Uncompensated Work.
¶ 6 In December 2008 and February 2009, respectively, Wang and Adobe filed separate, later-consolidated lawsuits against REM, KAI, Smoke Tree, and the other subcontractors, among others. Each of the other subcontractors filed a cross-claim against REM, KAI, and Smoke Tree. Although the details of the claims varied, all six subcontractors sought damages for breach of contract against KAI, sought to foreclose their mechanic’s liens, and in the alternative sought a money judgment against REM and Smoke Tree for unjust enrichment.
¶ 7 All subcontractors except Allied eventually moved for summary judgment against KAI on the contract claim and against Smoke Tree on the mechanic’s lien foreclosure and unjust enrichment claims. KAI did not oppose the motions, but Smoke Tree responded and filed cross-motions for summary judgment. After briefing and argument, the court granted summary judgment in favor of Smoke Tree on each mechanic’s lien claim, reasoning “that because the requirements for a mechanic lien were not strictly followed, there is no valid lien.” But the court granted summary judgment in favor of each subcontractor and against Smoke Tree on the unjust enrichment claims, ruling “[i]t would be unjust for Smoke Tree to retain the benefits of improvements to its property without compensating the subcontractors for their work.”
¶ 8 After denying Smoke Tree’s motion for reconsideration, the court entered judgment invalidating each mechanic’s lien at issue and awarding each subcontractor a money judgment on the unjust enrichment claims for the billed value of the Uncompensated Work. The court also awarded prejudgment interest beginning as of December 22, 2009, the date the court entered its order granting summary judgment against Smoke Tree for unjust enrichment. Although the subcontractors requested attorneys’ fees pursuant to Arizona Revised Statutes (“A.R.S.”) section
DISCUSSION
I. Smoke Tree’s Appeal
¶ 9 Smoke Tree first argues the superior court erred by entering summary judgment in favor of the subcontractors on their unjust enrichment claims rather than entering judgment for Smoke Tree. We review de novo the court’s grant of summary judgment and affirm only if, viewing the facts in the light most favorable to the party against whom judgment was entered, no genuine issue of material fact exists and the moving party is entitled to judgment as a matter of law. Orme Sch. v. Reeves,
¶ 10 An unjust enrichment claim requires proof of five elements: “(1) an enrichment, (2) an impoverishment, (3) a connection between the enrichment and impoverishment, (4) the absence of justification for the enrichment and impoverishment, and (5) the absence of a remedy provided by law.” Freeman v. Sorchych,
¶ 11 Smoke Tree argues that any enrichment was justified because the benefits received were specified under the lease with REM, and Smoke Tree did not act improperly. The subcontractors respond the enrichment was unjustified because Smoke Tree retained the benefit of unpaid labor and materials for tenant improvements it required, knowing the subcontractors expected payment. The superior court reasoned the enrichment was unjustified because “Smoke Tree approved the construction plans for the restaurant which was an integral part of Smoke Tree’s Resort.”
¶ 12 The subcontractors rely on authority addressing situations in which a subcontractor is not paid for labor and materials by a general contractor, and payment is sought from the owner under a theory of unjust enrichment. These cases fall into two categories: ones in which the owner has fully paid the general contractor and ones in which the owner has not fully paid the general contractor. Our courts have held that recovery under a theory of unjust enrichment is not available in the former category, because the owner is not unjustly enriched if it fully paid its obligation. A M Leasing Ltd. v. Baker,
¶ 13 Smoke Tree relies on the Colorado Supreme Court’s decision in DCB Construction Co., Inc. v. Central City Development Co.,
¶ 14 The court of appeals reversed, and the Colorado Supreme Court affirmed that decision. Id. When considering whether it would be unjust for the owner to retain the benefit of the contractor’s work without paying for it, the supreme court initially cited the general rule that when a non-owner contracts for improvements to the owner’s property and then fails to pay, “ ‘the owner is not liable to the contractor or supplier unless he agreed to pay them.’ ” Id. at 121 (quoting 3 Dan B. Dobbs, The Law of Remedies, § 12.20(3) at 473 (2d ed. 1993)). This rule protects rights of choice and recognizes that ordinarily, an owner should not be effectively forced into a legal relationship with a third party. Id. The court then noted that Restatement of Restitution (“Restatement”) § 110 (1937) provides, “[a] person who has conferred a benefit upon another as the performance of a contract with a third person is not entitled to restitution from the other merely because of the failure of performance by the third person.” DCB Constr.,
¶ 16 Applying our holding to the record before us, we conclude the superior court erred by ruling that Smoke Tree’s retention of the tenant improvements would be unjust unless it pays the amounts owed to the subcontractors. Although Smoke Tree required REM to make tenant improvements and agreed to reimburse REM for a substantial amount of its expenses, no evidence suggests Smoke Tree engaged in improper conduct, and the subcontractors do not allege improper conduct. For example, Smoke Tree did not directly engage KAI to construct tenant improvements and then withhold payment, knowing it would affect payment to the subcontractors. Cf. Flooring Sys.,
¶ 17 For these reasons, we hold that a contractor hired by a tenant to make improvements to leasehold premises, or subcontractors retained by that contractor, can recover unpaid monies for making tenant improvements from the property owner only when that owner has engaged in improper conduct.
II. Cross-appeals
A. Mechanic’s liens
¶ 18 All subcontractors except Beecroft
¶ 19 Arizona’s mechanic’s liens statutes, A.R.S. §§ 33-981 to -1008 (West 2012), protect laborers and materialmen (collectively, “Laborers”), who generally lack privity of contract with a property owner, by providing them with a lien on real property for the amount of labor and materials supplied and by allowing them to pursue remedies directly against the owner. United Metro Materials, Inc. v. Pena Blanca Props., L.L.C.,
1. Wang
a. REM as agent of Smoke Tree
¶ 20 A Laborer may record a lien on property only when it performed work or supplied materials at the “instance” of the property owner or the owner’s agent. A.R.S. § 33-981(A). Smoke Tree asserts Wang’s lien against its interest in the property is invalid because neither Smoke Tree nor anyone serving as its agent requested improvements to the restaurant. In a related argument, Smoke Tree contends Wang’s lien is invalid because Wang never served REM as “owner” with a preliminary twenty-day lien notice. Wang counters REM was Smoke Tree’s agent because the lease required REM to remodel the restaurant pursuant to plans and specifications approved by Smoke Tree. For this reason, Wang asserts it properly served Smoke Tree with a preliminary twenty-day lien notice and subsequently recorded a lien against Smoke Tree’s ownership interest.
¶ 21 A Laborer may not enforce against an owner a lien for work or material requested by a tenant unless the tenant acted as the owner’s agent. DeVry Brick Co. v. Mordka,
¶ 22 Like the leases at issue in DeVry Brick and Bobo, the lease here required REM to extensively remodel the restaurant. Also, REM was obligated to make improvements in accordance with plans and specifications approved by Smoke Tree and use a contractor approved by Smoke Tree. Despite these similarities, Smoke Tree argues DeVry Brick and Bobo are inapplicable because the lease here explicitly provided that “no mechanic’s or other lien for any ... work or materials [furnished to REM] shall attach to or affect [Smoke Tree’s] interest in the [premises” and represented that the sole relationship between Smoke Tree and REM was as landlord and tenant. This disclaimer, however, contravenes the legislature’s policy expressed in A.R.S. § 33-981(A) to permit liens against an owner’s interest in property when work is performed or materials furnished at the instance of the owner or its agent. Because the lease establishes that REM served as Smoke Tree’s agent for purposes of the lien statutes, the disclaimer cannot serve to invalidate Wang’s lien. See Liberty Mut. Fire Ins. Co. v. Mandile,
¶ 23 Pursuant to the holdings in DeVry Brick and Bobo, we hold the improvements to the restaurant were made at the “instance” of Smoke Tree through REM, and Wang was entitled to have a lien against Smoke Tree’s interest in the property. A.R.S. § 33-981(A). Additionally, Wang properly served Smoke Tree rather than REM with the preliminary twenty-day lien notice.
b. Timely service of lien
¶ 24 To perfect a mechanic’s lien, a Laborer, within a statutory time period, must “make duplicate copies of a notice and claim of lien and record one copy with the county recorder ... and within a reasonable time thereafter serve the remaining copy upon the owner of the building, structure or improvement.” A.R.S. § 33-993(A). Wang recorded its notice and claim of lien on September 23, 2008; approximately three months later it simultaneously served Smoke Tree with the lien and the complaint seeking to foreclose it. Smoke Tree argues Wang failed to comply with A.R.S. § 33-993(A) because appending the notice and claim of lien to the complaint and then serving both on Smoke Tree failed to constitute service “within a reasonable time” after recording the lien.
¶ 25 Smoke Tree relies on Old Adobe Office Properties, Ltd. v. Gin,
A.R.S. § 33-998 provides that a lien recorded under the provisions of Article 6 “shall not continue for a longer period than six months after it is recorded, unless action is brought within such period to enforce the lien.” Since the purpose of the notice requirement is to allow an owner an opportunity to protect himself and to investigate the claim, absent unusual circumstances, the notice requirement of § 33-993(A) will not be met merely by appending a copy of the notice and claim of lien to the complaint filed in an action to foreclose that very lien.
Id.
¶ 26 Smoke Tree characterizes the above-quoted language as meaning service of the notice and claim of lien with a complaint can never satisfy the “reasonable time” requirement of § 33-993(A), absent unusual circumstances. To the extent Old Adobe makes this holding, we disagree. The lien statutes do not mandate that any period of time pass between serving a lien and filing a foreclosure complaint. Thus, if the Old Adobe Laborer had served its complaint on the property owner along with the notice and claim of lien the day after recording the lien, service undoubtedly would have been within a reasonable time pursuant to § 33-993(A) regardless of the simultaneous service of the complaint. The pertinent issue in Old Adobe was whether taking this course of action almost six months after the Laborer recorded the lien was sufficient under A.R.S. § 33-993(A).
¶ 27 We cannot say as a matter of law that Wang’s service of the notice and claim of lien approximately three months after recordation was not within a reasonable time. The record before us does not set forth any facts bearing on Smoke Tree’s ability to investigate the claim or protect itself after service of the lien. Moreover, Smoke Tree does not offer any argument why service of the lien approximately three months after recordation was not reasonable. In light of the record developed thus far, summary judgment on this issue is not appropriate.
c. Acknowledgment of lis pendens
¶ 28 When a Laborer files a complaint to foreclose a mechanic’s lien, it must also record a lis pendens to provide notice of the lawsuit. A.R.S. § 33-998(A) (citing A.R.S. § 12-1191). Smoke Tree argues Wang failed to comply with this requirement because the lis pendens it recorded was not acknowledged as required of an “instrument affecting real property.” See A.R.S. § 33-411(A), (B) (West 2012). This court expressly rejected this argument in two recent decisions. Fagerlie,
2. Aero
a. Preliminary lien notice
Smoke Tree incorporates by reference its arguments concerning Wang to assert the same argument against Aero but fails to assert any facts or arguments specific to Aero. For the same reasons we reject Smoke Tree’s arguments concerning the propriety of summary judgment against Wang on this issue, we also reject them as applicable to Aero on this record.
¶ 29 As previously explained, to preserve lien rights, a Laborer must serve a preliminary twenty-day lien notice on the owner or reputed owner, among others, within twenty days after the Laborer first furnishes materials or services to the jobsite. A.R.S. § 33-992.01(B), (C). Smoke Tree contends Aero’s notice identified REM as the owner, and therefore Aero could not impose a lien against Smoke Tree’s interests. Aero counters it properly named Smoke Tree as the owner.
¶ 31 Smoke Tree’s challenge to Aero’s preliminary twenty-day lien notice is unclear. If Smoke Tree contends Aero never named Smoke Tree as owner in a notice, it is mistaken. To the extent Smoke Tree argues the amended notices extinguished the original notice naming Smoke Tree as the owner and thereby voided the later notice and claim of lien, we reject that argument. Section 33-922.01(B) requires service on the owner to permit it to investigate the claim and promote dialogue among affected parties to resolve payment issues and avoid “costly work stoppages, mechanics’ lien foreclosure sales, and double payments by the owner.’” Delmastro,
b. Legal description in notice and claim of lien
¶ 32 A Laborer is required to state in a notice and claim of lien “[t]he legal description of the lands and improvements to be charged with a lien.” A.R.S. § 33-993(A)(1). Aero provided the following description:
THE R.E.M. RESTAURANT AT THE SMOKE TREE RESORT 7101 EAST LINCOLN DRIVE SCOTTSDALE, MARICOPA COUNTY, STATE OF ARIZONA APN: 174 64 003 A — SMOKE TREE RESORT 865/15 CONTAINED IN EXHIBIT “A” AND INCORPORATED HEREIN BY THIS REFERENCE RECORDS OF MARICOPA COUNTY, STATE OF ARIZONA.
Smoke Tree argues this recitation fails as a “legal description” but does not explain how. Aero asserts listing the street address, the physical description of the property, and the county assessor parcel number, together with express incorporation of county records for that parcel number, was sufficient to comply with § 33 — 993(A) (1).
¶ 33 A Laborer must substantially comply with the legal description requirement in order to perfect a lien and later foreclose it. Smith Pipe & Steel Co. v. Mead,
3. Adobe
a. Survival of lien against leasehold interest
¶ 34 Unlike the other subcontractors, Adobe seeks to foreclose a lien only against REM’s leasehold interest in the property. Smoke Tree argues Adobe stands in REM’s shoes, and because REM no longer has a leasehold interest in the property, and Adobe never imposed a lien against Smoke Tree’s ownership interest, Adobe’s lien rights are extinguished. Adobe counters its lien survives termination of the lease and may be foreclosed.
¶ 35 Adobe relies primarily on Hayward Lumber & Investment Co. v. Graham,
¶ 36 On appeal, the supreme court agreed that because the improvements were made solely at the instance of the tenant, the liens only could be foreclosed against the tenant’s interests. Id. at 108,
¶ 37 Smoke Tree argues Hayward Lumber is distinguishable because the improvements at issue were entirely erected by the tenant, while Adobe’s improvements were made to a building owned by Smoke Tree. Because it is impossible to grant a lien against these improvements
¶ 38 We agree with Smoke Tree that Hayward Lumber is distinguishable because it involved construction of a building entirely at the tenant’s instance. The court’s focus was deciding whether the lien on the building could survive even though the Laborers could not impose liens on the underlying land. Hayward Lumber,
¶ 39 Nevertheless, Hayward Lumber provides guidance on the issue before us. The court reiterated the long-held principle that “only the lessee[’]s interests could be used to satisfy the mechanics’ liens” and emphasized its holding struck a balance in protecting both Laborers and landlord-owners. Id. at 108, 110-11,
It is undoubtedly the law in Arizona that only the interest of the party who causes the building to be erected or the materials to be furnished can be ordered sold to satisfy mechanics’ or materialmen’s liens, and where the owner of premises has leased them, a person furnishing material or doing labor for the lessee on the premises may have a lien against the particular estate of the lessee, but can have none against the owner’s estate in the property unless it appears that the lessee is actually an agent of the owner, or as a matter of law is estopped from denying such agency.
¶ 40 We derive two principles from Hayward Lumber and Demund Lumber. First, a Laborer’s mechanic’s lien imposed solely against a tenant’s interest in improvements made to leased premises survives termination of the lease if the landlord has no ownership interest in the improvements. Hayward Lumber,
¶ 41 Applying these principles to this case, we decide Adobe’s lien survived REM’s lease termination because, as previously explained, see supra ¶¶ 20-23, REM served as Smoke Tree’s agent for the purposes of the lien statutes. Because REM’s leasehold estate no longer exists, however, Adobe’s lien necessarily is one against Smoke Tree’s interests. See Trace Constr., Inc. v. Dana Barros Sports Complex, LLC,
b. Preliminary lien notices
¶ 42 Smoke Tree argues the superior court properly entered summary judgment against Adobe because it failed to serve Smoke Tree with a preliminary twenty-day lien notice. The record shows Adobe Paint served such a notice on Smoke Tree, so summary judgment was inappropriate against Adobe Paint on this basis.
¶ 43 Section 33-992.01(B) requires a Laborer who may later impose a lien to “serve the owner or reputed owner” with the preliminary twenty-day notice. Substantial compliance with this provision is a “necessary prerequisite to the validity of any claim of lien.” Id.; MLM Constr. Co., Inc. v. Pace Corp.,
4. Allied
¶ 44 The summary judgment entered against Allied is procedurally unique. Specifically, the superior court entered judgment against Allied on its mechanic’s lien foreclosure claim even though Smoke Tree never sought judgment against Allied and the parties did not stipulate to one. Neither party made any arguments concerning Allied’s lien, and the court explained only that all the subcontractors’ liens failed to comply with the lien statutes. On appeal, Allied simply joins the briefs of the other subcontractors without making any argument specific to it, and Smoke Tree asserts we have “no basis to reverse.” But we also have no basis to affirm. What’s an appellate court to do? We reverse. Any judgment entered on Allied’s mechanic’s lien foreclosure claim must await a dispositive motion, stipulation, or trial.
B. Attorneys’ fees
¶ 45 All subcontractors except Beecroft challenge the superior court’s refusal to award attorneys’ fees pursuant to A.R.S. § 12-341.01(A) because they prevailed on their unjust enrichment claims. In light of our decision reversing summary judgment on the unjust enrichment claims, the subcontractors are no longer the prevailing parties on these claims. Their challenges to the attorneys’ fees ruling are therefore moot, and we do not address them.
ATTORNEYS’ FEES ON APPEAL AND CROSS-APPEAL
¶ 46 All parties request an award of attorneys’ fees pursuant to A.R.S. § 12-341.01(A) and/or A.R.S. § 33-998(B).
¶ 47 We deny Beecroft’s request for fees pursuant to § 12-341.01(A) expended in the appeal, because Beecroft is not the successful party. We have discretion to award fees pursuant to § 12-341.01(A) in favor of Smoke Tree as against Beecroft because Smoke Tree is the successful party, and the unjust enrichment claim arises out of the contract between Beecroft and KAI. See Schwab Sales, Inc. v. GN Constr. Co., Inc.,
¶ 48 We deny the fee requests of Smoke Tree, Wang, Aero, and Allied. Sections 12-341.01(A) and 33-998(B) provide us discretionary authority to award fees. Because all these parties are partially successful and partially unsuccessful, we exercise our discretion to deny the requests. See Murphy Farrell
DISPOSITION
¶ 49 We reverse the entry of summary judgment in favor of the subcontractors on their claims for unjust enrichment and remand with directions for the court to enter summary judgment in favor of Smoke Tree on those claims.
¶ 50 We reverse the summary judgments entered against Wang, Aero, and Allied on their claims to foreclose mechanic’s liens against Smoke Tree and remand for further proceedings.
¶ 51 We reverse the summary judgment entered against Adobe on its claim to foreclose mechanic’s liens against Smoke Tree and remand with instructions to enter summary judgment in favor of Adobe on that claim. We further instruct the court to permit Adobe to apply for attorneys’ fees on its mechanic’s lien claims pursuant to A.R.S. § 33-998(B). We award Adobe its reasonable attorneys’ fees and costs expended in its cross-appeal subject to compliance with ARCAP 21(a).
¶ 52 We deny Smoke Tree’s request for attorneys’ fees against Beecroft, but award Smoke Tree its taxable costs subject to compliance with ARCAP 21(a).
¶ 53 We deny all remaining requests for attorneys’ fees and taxable costs.
CONCLUSION
¶ 54 For the foregoing reasons, we reverse and remand with instructions.
Notes
. Adobe argues the declaration lacks foundation and is therefore insufficient to show that Smoke Tree paid any amounts to KAI. The record does not reflect that Adobe or any other subcontractor objected to the declaration before the superior court. Adobe has therefore waived this argument. See Trantor v. Fredrikson,
. Allied later moved for summary judgment on its unjust enrichment claim, and Smoke Tree and Allied stipulated to entry of summary judgment for Allied in light of the court's earlier summary judgment rulings. The court also entered judgment against Allied on its mechanic’s lien foreclosure claim.
. Absent material revision after the date of the events at issue, we cite a statute's current version.
. Although the Stratton court rested its holding on the principle that unjust enrichment cannot apply against an owner when a contract exists between the general contractor and the subcontractor,
. See Hayes Mech., Inc. v. First Indus., L.P.,
. This court has previously stated that "the doctrine of unjust enrichment has no application to the owner where an explicit contract exists between the subcontractor and the prime contractor.” Stratton,
. Beecroft did not appeal entry of summary judgment on its mechanic’s lien foreclosure action. Therefore, we do not review the propriety of that summary judgment.
. For these same reasons, we reject Smoke Tree’s arguments that (1) Aero had no right to impose a mechanic’s lien against Smoke Tree’s interest in the property, and (2) Aero improperly served a preliminary twenty-day lien notice on Smoke Tree because REM was not Smoke Tree’s agent for purposes of the lien statutes.
. Smoke Tree incorporates by reference its arguments concerning Wang to assert the same argument against Aero but fails to assert any facts or arguments specific to Aero. For the same reasons we reject Smoke Tree’s arguments concerning the propriety of summary judgment against Wang on this issue, we also reject them as applicable to Aero on this record.

. Smoke Tree does not argue the effect, if any, of Adobe Paint’s failure to serve REM with a preliminary twenty-day notice, and that issue is not before us.
