delivered the opinion of the Court.
This case involves the title to an undivided one-half of the minerals under a certain tract of 103.7 acres of land in Harrison County. Petitioner, Whiteside, purchased this mineral interest while there was an outstanding purchase-money lien on the entire tract. Subsequently the land was reconveyed to the holder of the vendor’s lien notes and in cancellation thereof.
In 1916 the land was conveyed to Howard Spann with *413vendor’s lien retained. In 1919 Spann conveyed the one-half mineral interest and the purchaser, a few months later, by quitclaim deed conveyed this property to Whiteside, a resident of Minnesota. The notes were extended from time to time and ultimately were transferred and assigned to A. L. Webster. In 1932 Spann and wife conveyed this tract to A. L. Webster reciting the consideration as follows:
“That we, Howard Spann and his wife, Irine Spann of the County of Harrison and State of Texas in consideration of the cancellation and surrender of four certain notes of a series of six vendor’s lien notes said four notes being due one each on November 18th, 1919, November 18th 1920, November 18th 1921 and November 18th 1922 and having been given as part of the purchase price of the tract of land hereby conveyed and which notes were and have been kept in full force and effect as well as the lien securing the same by extension agreements shown of record in the records of Harrison County, Texas, said four notes together with the vendor’s lien given to secure the same now being past due and constitute a valid indebtedness and lien against the land hereby conveyed which indebtedness we are not able to pay; and which indebtedness together with the lien securing same is now owned and held by A. L. Webster grantee herein;”
That conveyance was promptly placed of record.
It is shown that Whiteside, after placing his deed of record, paid all state and county taxes due and owing on the property and that his address was posted on the records of the tax collector. It also appears that he had no actual notice of the re-conveyance of the tract to Webster until shortly before he filed an answer in this cause. Thus some 27 years had intervened.
This suit was filed by respondents, Bell and others, successors in title to A. L. Webster in the usual form of trespass to try title. Both parties moved for summary judgment. Bell’s motion was granted by the trial court and judgment entered awarding title. The judgment has been affirmed by the Court of Civil Appeals. 336 S.W. 2d 930. We concur in that result.
Petitioner, Whiteside, contends (1) that the transaction between Webster and Spann did not in law constitute a rescission of the original sale to Spann; (2) there could be no rescission eliminating Whiteside’s interest without notice to him of an *414intention to rescind, and (3) that Whiteside was not required to assert his equities within a reasonable time after the recording of the deed from Spann to Webster.
We recognize the holding in Maupin v. Chaney, 139 Texas 426, 163 S.W. 2d 380, 384, as follows:
“As the holder of the vendor’s lien and superior title they had a right to rescind the conveyance upon default by the defendants. Whether or not they did rescind the contract of sale will depend on their intentions, as well as their acts and conduct in the premises. In order to constitute a rescission there must be an election on the part of the holder of the superior title to so rescind, and in order for there to be such an election there must be an intention to so elect. 29 Tex. Jur. 920.”
Under the facts in this case, however, we believe the trial court was warranted in concluding that there was a rescission as a matter of law. Webster was dead at the time suit was filed. Spann executed an affidavit that sheds no light and adds nothing to the recital of facts in the deed of conveyance. Rescission is a unilateral right resting with the holder of the notes. Having the right to rescind and to recover all of the land to which his lien attached in the absence of anything to the contrary, we think it would naturally be presumed that he did intend to rescind and exercise all the rights to which he was entitled. The conveyance from Spann back to Webster purported to convey all of the 103.7 acre tract and in fact described it as “being the identical tract of land conveyed to Howard Spann by W. R. Sherrod et al by deed shown of record.” Of course the lien held by Webster was valid and subsisting as to the entire tract including the mineral interest.
While we have found no authority squarely passing on the question here involved we think a brief reference to some well-established principles will be helpful.
The courts of our state have long been committed to the proposition that a deed conveying land and reserving a lien for the unpaid purchase money is treated as an executory contract that will ripen into a title in the purchaser when he has performed his obligation to pay the purchase money. It is accordingly held that when the vendee refuses to pay the vendor may claim an immediate rescission and recover the land. That right *415is not waived by an agreement for the extension of the time of payment except during the period of extension. Lanier v. Faust, 81 Tex. 186, 16 S.W. 994.
Where the vendee defaults in the payment of the purchase price there are several remedies available to the vendor. He may file a suit for debt and foreclosure. He may file a suit in trespass to try title to recover the land thereby effecting a rescission. Rescission may be accomplished by agreement between the parties. Vendor may also rescind by reentering upon the land and taking possession thereof, or by executing a deed to some third party which may amount to a repudiation of the sale to the original vendee. Admittedly in a situation of this kind where the rights of the subvendee are involved, those rights may not be prejudiced either by foreclosure or rescission. The subvendee would have the right in equity to pay off the indebtedness or have a marshalling of the assets, namely, as in this case, that the surface and one-half of the minerals be devoted to the extinguishment of the debt before application of the lien to his 50-acre mineral interest. R. B. Spencer & Co. v. May, 78 S.W. 2d 665, wr. ref.
Although a subsequent vendee is not a necessary party to the lien foreclosure his right to become the owner of the legal title by paying the purchase price is not cut off by the suit. He could intervene and tender the amount of the indebtedness and even after judgment in the foreclosure suit he could accomplish the same result by tendering the proper amount provided he acts within a reasonable length of time. State v. Forest Lawn Lot Owners Ass’n., 152 Tex. 41, 254 S.W. 2d 87; Howell v. Townsend, Tex. Civ. App., 217 S.W. 975, wr. ref.; Wier v. Yates, Tex. Civ. App., 237 S.W. 623, wr. ref.
So the problem here really comes down to the question of whether or not the burden is upon the lienholder to give notice to the subvendee of his intention to rescind or whether it is the subvendee’s obligation to make the necessary inquiry himself. The decision necessarily works some hardship on one or the other of the adverse parties.
The theory of Whiteside is that the vendor must bring home notice to the subvendee of his intention to rescind and that there is no obligation on the subvendee to make inquiry as to whether or not the original vendee has paid the purchase price and acquired title, thus in turn making the title of the subvendee secure.
*416Petitioner takes the position that the subvendee must have adequate notice of the vendor’s rescission of the original contract for the sale of the land where the vendor does not resort to judicial action. In support of that contention he cites several decisions by this court which we shall discuss briefly.
In Phillips v. Herndon, 78 Tex. 378, 14 S.W. 857, the court held that the vendor was not entitled to rescind the sale to his vendee without giving notice of his intention so to do. The same situation obtained in Heirs of Reddin v. Smith, 65 Tex. 26. Neither of the above decisions concern the rights of a subvendee.
In Huffman v. Mulkey, 78 Tex. 556, 14 S.W. 1029, Evans conveyed to Parman reserving vendor’s lien; Parman conveyed to Evans and Huffman who were partners in a mercantile business. The court held that if Evans knew of and recognized the validity of the deed to himself and Huffman and authorized the same he could not resist the right of Huffman to recover any interest in the land which the facts may entitle him to, even though the notes of Parman were past due when the deed was made to Evans and Huffman and although Evans was in possession of the land.
In Tom v. Wollhoefer, 61 Tex. 277, the court observed that “Parties dealing with the vendee before his part of the contract has been complied with, do so with full knowledge of the vendor’s rights, and cannot ordinarily be heard to complain, if, by reason of default on the part of the purchaser, their contracts with him are rendered of no avail.” The court held, however, that there were such equities in favor of a mortgagee of the purchaser as to prevent a rescission without a recognition of the mortgagee’s rights against the property.
None of these cases, we think, bear out petitioner’s contention that a subvendee must have notice of the vendor’s intention to rescind.
In the principal case relied upon by the Court of Civil Appeals, Revard et al. v. Wood et al., Tex. Civ. App., 156 S.W. 2d 561, wr. ref. w.o.m., the subvendee was not made a party to the foreclosure suit and the court held that it was not necessary that she be made a party. She merely contended that since the notes that she had executed to the original vendee were barred at the time of her suit by the 4-year statute of limitation and since she was not made a party to the foreclosure suit she was vested with *417the superior title to the portion of the land that she had bought. The court points out that had she used due diligence in setting up her equity and tendering the amount due on the original vendor’s lien notes that she might have obtained relief but not so after waiting 15 years, long after the notes are barred and without tendering the amount due.
In Williams v. Coleman-Fulton Pasture Co. et al., Tex. Civ. App., 157 S.W. 2d 995, wr. ref. w.o.m., a subvendee was held not to be a necessary party to proceedings to foreclose a vendor’s lien and his equitable right to complete payment of the purchase price and acquire title was barred by laches after 18 years had elapsed from the time of entry of the foreclosure judgment during which time oil was discovered and being produced therefrom.
Howell v. Townsend, Tex. Civ. App., 217 S.W. 975, wr. ref., holds that the original vendor is not required to make subvendees parties to a suit for foreclosure of the vendor’s lien but that the subvendee must protect his own equities in the land and this is true for the reason that the original vendee has no right to force any third person into the contract with his vendor.
In summary we say that the authorities hold in this state that in a foreclosure a subvendee is not a necessary party, but that he may step into the shoes of his defaulting vendee, tender the amount due and recover the title provided he acts within a reasonable length of time.
We see no reason for not applying the same rule to this case where there has been a rescission instead of a foreclosure. The result has been the same. The notice given constructively by a judgment in foreclosure is no more effective than the recording of the deed of reconveyance. We think 27 years is more than a reasonable time for Whiteside to have acted. While the record does not show the discovery or production of oil on the premises yet it does show a lease was executed by Bell and others to the Atlantic Refining Company in 1951. At any rate, aside from the discovery of oil we know as a matter of common knowledge that in such period of time land values have increased greatly in all sections of the state.
The consideration recited in the mineral deed from Spann to Whiteside’s vendor was $50.00. While the price paid by Whiteside is not shown there is no reason to believe that this property had *418increased substantially in value in the few months between these two conveyances in 1919. Whiteside knew at the time of his purchase that the entire tract was burdened with the outstanding purchase money lien and subject to foreclosure or the rescission of any other rights legally vested in the holder of the notes and lien. Twenty-seven years have elapsed since the deed from Spann to Webster was placed of record. In the meantime A. L. Webster in 1945 conveyed the land to Bell reserving an undivided one-half interest in the minerals for a term of 20 years. Webster died in 1946. The rights of third parties have intervened. The facts that Whiteside had paid the state and county taxes for all of these years and that his name was to be found in the tax collector’s records do not constitute notice, actual or constructive, and will not serve to bolster his claim.
Laches is defined as “an unexcused delay in asserting rights during a period of time in which adverse rights have been acquired under circumstances that make it inequitable to displace such adverse rights for the benefit of those who are bound by the delay;” 30 C.J.S., Equity, § 112.
We are of the opinion that under the facts before us it would be inequitable to recognize the validity of Whiteside’s claim. He is barred by the operation of laches and we so hold.
The judgments of the trial court and the Court of Civil Appeals are affirmed.
