OPINION
This case involves a dispute concerning lien priority and title to real property. The trial court overruled appellant’s motion for summary judgment and granted appellee’s motion for summary judgment. Appellant has perfected its appeal to this court.
We reverse and render.
Both parties agree that there is no issue of material fact to be resolved. The dispute centers upon the judicial construction of their lien priority. It is necessary, for the disposition of this case, to discuss the undisputed pertinent facts with regard to title transfers and liens upon the property in dispute.
Both parties claim a common source of title. The property was owned by John Porter Auto Sales (“Porter”). Porter sold the property to Lawrence Investments, Inc. (“Lawrence”) in 1976. Porter retained a vendor’s lien which was secured by a deed of trust executed by Lawrence. Lawrence executed a note to evidence the unpaid purchase price of the property (“Porter note”).
Thereafter, Lawrence sold the property to Allibhai Corporation (“Allibhai”) in January of 1980. The sale was made subject to the Porter lien. Allibhai executed a note to evidence the unpaid purchase price of the property (“Lawrence note”) which was secured by a deed of trust. The Lawrence note was a wrap-around mortgage which “wrapped” the Porter note.
Sometime later in that year the city of Denton filed a tax lien against the property for delinquent property taxes.
In January of 1981, Allibhai obtained a loan from First City Bank — Farmers Branch (“First City”). Allibhai used the property in question as collateral for the loan. It secured the note to the bank by a deed of trust. Of the loan proceeds, $6,507.72 was used to satisfy the tax lien upon the property; $71,218.08 was used to satisfy the remainder of the Porter note. The remainder of the funds borrowed from First City were used to remodel a motel which was situated on the property.
In August 1983, Allibhai sold the property to Canindusa. The sale was made subject to the Lawrence lien. Thereafter, the debt between Allibhai and Lawrence became delinquent and Lawrence began foreclosure proceedings upon the property. A dispute concerning priority of liens arose between First City and Lawrence.
Appellant, Chicago Title Insurance Company (“CTIC”) is the insurance underwriter who had insured the bank’s lien as a first and superior lien on the property under a mortgagee policy of title insurance. When the dispute concerning lien priority arose between First City and Lawrence, CTIC purchased the note held by the bank for $113,593.91 and obtained an assignment of the note from the bank. Both litigants posted the property for separate trustee’s sales to be had on the same day. 'Each party purchased the property at its respective trustee’s sale. Thereafter, CTIC sued for a declaratory judgment, seeking to establish superior title to the property by asserting a superior subrogation lien as against the vendor’s lien and deed of trust lien held by Lawrence. Lawrence cross-claimed a trespass to try title action. Both parties moved for summary judgment for title. Appellant’s motion for summary *334 judgment was denied. Appellee’s motion for summary judgment was granted.
In appellant's two points of error it complains that the trial court erred in denying its motion for summary judgment and in granting appellee’s motion for summary judgment.
Appellant contends that because the proceeds of the note from First City to Alli-bhai were used to pay the tax lien and the Porter lien the bank became equitably sub-rogated to these liens. Both parties agree these were the senior liens upon the property. Further, since appellant has been assigned the rights of the bank with regard to this piece of property, appellant contends it is equitably subrogated to these liens.
Subrogation is a doctrine of equity. It substitutes another person in the place of the creditor so that person in whose favor subrogation is applied succeeds to the right of the creditor in relation to the debt.
Fishel’s Fine Furniture v. Rice Food Market,
When the creditor ... has a security from the principal obligor, or either of them, or if the debt itself constitutes a lien upon property of the debtor, as a vendor’s lien, or if, from its nature, it be entitled to priority in payment over other debts of the debtor, the person paying the debt, not being a volunteer, will be subrogated to the securities, liens, and priorities of the creditor to the extent that he makes payment on the debt; ...
Id.
Turning to the case at bar, appellant contends that because the proceeds from the bank loan were utilized to pay off liens which had priority, the bank assumed a position of priority to the extent of those liens. Further, because the bank stood in the shoes of the prior lienholder and CTIC now stands in the shoes of the bank, appellant (CTIC) contends that it had the senior lien. We recognize that a person cannot be a mere volunteer to subrogation. He must be protecting an interest which would be jeopardized if the debt was not paid.
McDermott v. Steck Co.,
Subrogation is not self-executing, it must be asserted at some proceeding.
Johnson v. Koenig,
Appellant’s case turns on the law established in
Diversified Mortgage Inv. v. Lloyd D. Blaylock Gen. Contractor, Inc.,
We hold that appellant has a prior lien to the extent that the bank’s funds were used to pay off the tax lien and the Porter lien. Further, under
Diversified,
appellant has a superior title interest. Appellant, in holding a trustee’s sale under the deed of trust it had obtained from the bank by assignment, was exercising the method appropriate to foreclosing its lien interest under the bank’s subrogation to the lien interest held by Porter. The title then vested in CTIC, as purchaser, free and clear of the lien claims of Lawrence.
See Diversified,
The matter of division of the sale proceeds has not been raised and is not before us. Appellant’s first and second points of error are sustained.
We reverse the judgment of the trial court and render judgment in favor of appellant.
