By а general warranty deed executed on May 14, 1947, and recorded two days later, Petitioners, Luther T. McClung and wife, plaintiffs below, conveyed seventeen separate traсts of land totalling approximately 1,800 acres to Respondents, C. A. Lawrence and wife, defendants below. The general warranty clause was preceded by this reservation which also appears in the consideration clause of the deed:
“The grantors hereby reserving unto themselves one fourth of all of the oil, gas and/or minerals in on or uрon the above described land; however the grantees herein their heirs and assigns are hereby empowered and authorized to lease said land for oil gas or other minеrals without the joinder of the grantors herein in making any such lease or leases; and it is expressly stipulated that said grantors their heir or assigns shall not participate in any bonus or dеlay rentals paid grantees underany such lease or leases upon the leasing of said land the interest of the said grantors their heirs and assigns shall be and become a ⅜2 (onе thirty second) royalty interest under such leases it being the intention hereby to reserve and retain in said grantors a non participating ⅜2 royalty interest in and to the oil gas or other minerals in on or under the land hereby conveyed.
“TO HAVE AND TO HOLD the above described premises together with all and singular the rights and appurtenances thereto in anywise belonging unto the said C A Lаwrence and Mattie L Lawrence and unto their heirs and assigns forever; and we do hereby bind ourselves our heirs and assigns forever; and we do hereby bind ourselves our heirs executоrs and administrators to Warrant and Forever Defend all and singular the said premises unto the said C A Lawrence and Mattie L Lawrence and unto their heirs and assigns against every persоn whomsoever lawfully claiming or to claim the same or any part thereof.”
There were outstanding mineral and royalty interests in some of the tracts of land at the time of the сonveyance, the existence, but not the extent, of which appear to have been generally known to the parties. Many years later a controversy developed between them. Petitioners claimed they were entitled in all instances to an undivided ½2 royalty interest upon the leasing of the tracts by Respondents, and to establish such rights filed this suit in 1963. They sought a favorable construction of the deed in such respects and also sought its reformation upon the theory that by mutual mistake of the parties the deed failed to mаke clear that the reservation of the nonparticipating royalty interest was in addition to any prior reservations of minerals or royalties in, on or under any of the seрarate tracts. The answer of Respondents included pleas of limitation and laches in response to which Petitioners specially alleged that neither of them knew or should have known by the exercise of reasonable diligence that the deed did not conform to the agreement and intention of the parties until less than four years prior to the institution of the suit; and that they had been paid their full ½2 nonparticipating royalty interest under division orders executed by both parties or by Respondents alone. Petitioners movеd for a summary judgment upon their plea for reformation of the deed. Respondents moved for a summary judgment on the basis that such was barred by the four-year statute of limitation. The triаl court granted Respondents’ motion and the Court of Civil Appeals affirmed upon the twofold holding that the deed is unambiguous and should be construed favorably to Respondents under the rule of Duhig v. Peavy-Moore Lumber Co.,
It was held in
Duhig
that the grantor in a general warranty deed is estopped to claim title to an interest reserved therein when to permit him to do so would, in effect, breach his warranty with respect to the title and interest which the deed purports to convey. Miles v. Martin,
The contractual provisions which were determinative in
Scharbauer
and
Mc-Lain
are not present in the words of the deed here. The instrument does not require that it be provided in leases which Respondents were authorized to execute that Petitioners be paid ⅜2 of the royalties. To the contrary, the royalty interest provision is written in terms of a reservation of a nonpаrticipating royalty interest “in and to the oil gas or other minerals in on or under the land hereby conveyed,” and the interests would normally correspond, i. e., ¼ of the usual ⅛ royalty resеrvation. But in any event, the royalty interest reserved by Petitioners arises by virtue of the mineral reservation upon the leasing of the tracts of land by Respondents; as stated in the royalty clause, the reserved mineral interest of Petitioners “shall be and become a ⅜2 (one thirty second) royalty interest under such leases.” The problem here is that there werе outstanding mineral and royalty interests in some of the seventeen tracts of land, the nature and extent of which are not clear from the record. Under the rule of
Duhig,
and as to each separate tract, cf. Forrest v. Hanson,
As before noted, Petitioners alternatively sought a reformation of the deed upon allegations that by mutual mistake of the parties the instrument failed to clearly provide that the reservation of the royalty interest was in addition to any prior rеservations of minerals or royalties with respect to any of the separate tracts. Respondents’ motion for' summary judgment against Petitioners’ suit for reformation rested upon the fact that the deed was executed by Petitioners and filed for record in May, 1947, approximately sixteen years prior to the institution of the suit. It was the opinion of the Court оf Civil Appeals that as a matter of law Petitioners were charged with knowledge of the provisions of the deed from the date of its execution, and that limitation commenced to run against them from such date. Kahanek v. Kahanek,
It is so ordered.
