delivered the opinion of the court.
The trial court found that, though S. R. Templeton was ill when the oral agreement was entered into, he was' nevertheless competent to make a valid contract, and in this conclusion we fully concur, without setting out any of the testimony in support thereof.
The only.evidence offered tending to show the value of the interests in the mining claims, which the answer admits the deceased owned when the contract in question was entered into, was a copy of the inventory of his estate, showing an appraisement of such interests in the sum of $250. The defendants’ counsel did not call the appraisers as witnesses to prove their qualifications to express an opinion as to the value of such interests. Their estimate of the worth of the property as evidenced by the inventory cannot be much more competent than that of the county assessor, as noted in the assessment roll indicating his opinion thereof. If the undivided interests claimed by defendants as heirs were worth more than $100, the sum agreed to be paid therefor, witnesses undoubtedly would have been *67secured who would have so testified, but, in the absence of such testimony, we are satisfied that an adequate consideration was offered and accepted for the real property intended to be conveyed.
These preliminary questions having been settled in plaintiff’s favor, the important question to be considered is whether or not his possession of the mining claims constituted such a part performance of the terms of the agreement as to take the case out of the statute of frauds. The weight of authority supports the doctrine that an oral contract to convey real property, entered into between cotenants, whereby the purchaser takes possession of the interest of his vendor in the premises, will not be specifically enforced in equity: Pomeroy, Spec. Perf. § 121; Haines v. McGlone, 44 Ark. 79; Peckham v. Balch, 49 Mich. 179 (13 N. W. 506); Workman v. Guthrie, 29 Pa. 495 (72 Am. Dec. 654); Galbreath v. Galbreath, 5 Watts, 146. The reason for this rule lies in the fact that possession of real property under an oral contract for its purchase must be exclusive to operate as a bar to the statute (Hart v. Carroll, 85 Pa. 508), and as the possession by a tenant in common is presumed to be in favor and for the benefit of his cotenants (Morrill v. Morrill, 20 Or. 96, 25 Pac. 362, 11 L. R. A. 155, 23 Am. St. Rep. 95), it follows that one cannot, by purchase, secure the interests of the others except by a writing evidencing a transfer of the title. .It has been held, however, that where a cotenant owning a moiety of land receives from his cotenant the exclusive possession of the premises under an oral contract of purchase the specific performance of the agreement will be decreed: Peck v. Williams, 113 Ind. 256 (15 N. E. 270); Littlefield v. Littlefield, 51 Wis. 25 (7 N. W. 773). The cases to which attention has been called relate to the possession of real property taken by a cotenant in pursuance of an oral agreement to purchase the premises.
If, however, it be assumed that a stranger to the title can by such a contract take possession of an undivided interest in land, and enforce a specific performance of the oral agreement, we do not think plaintiff can exercise that right. The testimony shows that one A. C. Hausman, who was a tenant in common *68with S. B. Templeton and others in the mining claims, entered into a contract with plaintiff whereby the latter" was, without any payment to be made therefor, 'to prospect the mines for gold, and, if he discovered any, he had the privilege of erecting a stamp mill for the reduction of the ore to be extracted, and on the completion of the building furnished with suitable machinery he was to receive a deed conveying to him an undivided one half of the mining claims. In pursuance of this agreement, he, on June 6, 1902, began extending a tunnel into the IXL mine that had been commenced by the owners, and was working thereat June 29th of that year, when he entered into the contract with Templeton for the purchase of his interests in the mining claims. As a witness in his own behalf, plaintiff testified that he worked at the mine until Templeton became ill, when he sent word to Hausman that he would not do any more prospecting under the terms of their agreement, and that thereafter, having purchased Templeton’s interests, he immediately took possession thereof, and began to develop the mines as the owner of such interests, extending the tunnel 30 feet and making a cross-cut in the mine of nine feet. On cross-examination defendants’ counsel, referring to the contract entered into with Hausman, propounded the following question to plaintiff: “How long did you work under that agreement ?” to which he replied, “Until I bought Mr. Templeton’s interest.” It further appears from the testimony that two days prior to plaintiff’s purchase he sent a notice to Hausman of his intention to abandon the terms of their agreement. No evidence was offered tending to show that Hausman received such notice, and the fact that plaintiff continued developing the mine until he made the agreement with Templeton tends to show that he never surrendered his right of possession under the original contract with Hausman. To entitle a party to a specific performance, of an oral contract to convey real property it must affirmatively appear that the possession was taken in pursuance of and under the agreement alleged in the complaint: Brown v. Lord, 7 Or. 302; Sutton v. Myrick, 39 Ark. 424. It will be remembered that plaintiff was in possession of the mining claims under the Hausman contract, and *69that such possession was never relinquished, but merged into that assumed under the Templeton agreement. There was, therefore, not such a change of possession as to impart notice of plaintiffs right under the oral contract, and for this reason the decree is affirmed. Affirmed. .
