C. W. Coffield?” The jury answered “Yes.” On other issues the jury found that the agreement was made before the Butler deed was executed; that Sorrells procured the Butler deed to Coffield pursuant to the agreement; that the agreement was never revoked by mutual consent of the parties; that Sorrells effected a sale of 30 acres of minerals under the land to a third party for $1200; and that the agreement was not conditioned on Sorrells “immediately and without waiting future oil development procuring a sale of a part of the minerals so as to reimburse C. W. Coffield.” (Italics ours.)
Thus it is clear that Sorrells chose to try his case on the theory that he was to become a “joint owner” of the land “as and when” sufficient mineral interest was sold to reimburse Coffield, which, as Sorrells testified, might happen “in 10 years or ten days or twenty years or 20 days.” So Sorrells’ rights here must be measured within the limits which he thus set for himself. Safety Casualty Co. v. Wright, 138 Texas, 492, 160 S. W. (2d) 238, 245, and authorities there cited.
That portion of the English Act for the Prevention of Frauds and Perjuries declaring that all trusts in land must be evidenced by writing signed by the party declaring the trust was not included in our Statute of Frauds, Art. 3995, R. S. 1925. Therefore, such trusts may be proved by parol in Texas. James v. Fulcrod, 5 Texas, 512, 55 Am. Dec. 743, is an early illustrative case.
However, we impose definite limitations.
Allen v. Allen, 101 Texas, 362, 107 S. W., 528, holds that the transaction cannot be proved if it conflicts with those sections of the Act which we did adopt. Other cases say that the transaction must be in harmony with general principles of law. In other words, a trust may arise only from an enforceable contract. Whittenburg et al v. Miller, 139 Texas, 586, 164 S. W. (2d) 497.
So, where one Peaden claimed he had taken title to certain minerals from one Dr. Clayton in trust for one Ancell and in support thereof testified, “George B. Ancell came to me and asked me to secure it for him upon the understanding that he would pay me, reimburse me, whatever amount I was out if it was within reason,” this court said: “Under our view not only was the evidence not clear, satisfactory and convincing but there is no evidence at all of the presence in the agreement of certain elements requisite to the creation of a parol trust. The weakness is not so much in the clarity of the evidence as it is
