Plaintiffs assign error of the trial court in hearing this cause as a proceeding in equity and assert that the demurrer of plaintiffs to the defendant’s answer should have been sustained. Error is also predicated upon the entry of the decree in favor of respondent.

*258 Section 390, Or. L., provides, among other things, that in an action at law where the defendant is entitled to relief, arising ont of facts requiring the interposition of a court of equity, and material to his defense, he may set such matters up by answer without the necessity of filing a complaint on the equity side of the court. The application of this provision in this suit is challenged by the plaintiffs.

There is no dispute but that after the execution of the contract of sale was executed by plaintiff and defendant, in order for the defendant Roberts to obtain a loan on the land, which was for the benefit of Cop-pock and was to satisfy the payment for the land to the extent of the loan, that the plaintiffs by mutual consent of the parties assigned the contract of sale to defendant Roberts in order that it might be shown that there was a clear title to the land in him.

At the time of the assignment it was agreed between the parties that Roberts would execute with plaintiffs a new contract of sale of the land similar in all respects to the former contract, covering conditions of sale as formerly stipulated in the contract assigned to Roberts. Such new contract of sale was to be executed and delivered as soon as a loan, then being negotiated by Roberts from the California Joint Stock Land Bank of San Francisco, could be secured.

At the time of the commencement of the action at law the situation was that the plaintiffs claimed a rescission of the contract of sale of'the farm, while the defendant claimed that the contract was practically suspended during the time of making the loan, and that according to the written stipulations of the parties, made at the time the arrangements for the loan were perfected, a new contract similar to the *259 old one should he executed and delivered to plaintiffs and be in full force and effect. The effect of defendant’s answer was to secure a reinstatement of the terms of the original contract of sale. In this condition the controversy between the plaintiffs and defendant could not be tried or adjusted without bringing- into the case the matter of reinstatement of the original contract, or in form the execution of the new contract of sale.

If the claim of defendant is true, he is entitled to the relief of having the original contract of sale reinstated. Such relief arose out of facts requiring the interposition of a court of equity. They were material to the defendant’s defense. A new contract of sale, pursuant to the written agreement of the parties made on July 20, 1922, paving the way for obtaining the loan, could not be adjudged in an action at law. The enforcement of the contract between the parties, which was to serve their purpose during the interim between the time the contract of sale was assigned to Roberts and the time when the loan would be secured, could only be obtained in a suit in equity: 25 R. C. L. 202, § 2; Acton v. Lamberson, 102 Or. 472, 483 (202 Pac. 421, 202 Pac. 732); Crossen v. Campbell, 102 Or. 666 (202 Pac. 745); James v. Wards, 96 Or. 667 (190 Pac. 1105); Lind v. Boulin, 97 Or. 332 (190 Pac. 1103); Mendelsohn v. Mendelsohn, 104 Or. 281, 287 (207 Pac. 158); Gellert v. Bank of Cal. Nat. Assn., 107 Or. 162, 184 (214 Pac. 377); Anderson v. Hurlbert, 109 Or. 284 (219 Pac. 1092). There was no error in overruling plaintiff’s demurrer to defendant’s answer.

In order for plaintiffs to prevail it was necessary for them to sustain their contention that a mutual rescission of the contract of sale took place at *260 the time of a conversation between the parties at Dr. Pemberton’s office in Salem, Oregon.

Dr. Pemberton, as a witness for plaintiffs, testified thus in relation to such discourse:

“ * * there was two or three propositions. None of them very definite, none of them accepted and none of them very clear, but finally Mr. Roberts told him to make a list of his stock and implements and what improvements he had put on the place and come back and they would talk it over and have some kind of a settlement.”

The plaintiff, Charles B. Coppock, as a witness testified to the effect, that in the fall of 1921, the situation was such that he could not meet his obligations on account of the crops being poor. He was then owing the defendant, in addition to the balance of the price of the land, $1,000 which Roberts had paid on a tractor to use upon the farm, interest due and taxes paid by Roberts amounting to $2,513, for which he gave Roberts an unsecured note. “I asked to be released from the contract, and get a settlement.” Roberts said he would think the matter over. Cop-pock further stated: “I told him that inasmuch as he had agreed to deliver me a contract at the time the loan was made, I didn’t feel like I wanted to go ahead. I told him I had lost confidence in him and didn’t want to go ahead.” “I was afraid to say anything to him for fear he would attach everything I had and leave these other men (creditors) out in the cold. So I went and put the chattel mortgage on the stock.” Roberts said he was going away to the coast. The next time he saw him Roberts said the only thing he had to do, was for him to go ahead with the contract, just as it read. When he told Roberts about the chattel mortgage, Roberts was *261 “put out.” “I told him I would move off the place and give him my stock and implements, if he would come on and take it, I would move off and give it to him. * * He didn’t ever come out to the place after that.” Coppock states: “I haven’t seen Mr. Roberts since that to do any business with him.” (Referring to the conversation with reference to the chattel mortgage.) The testimony does not show that Coppock and Roberts ever consummated any settlement or arrangement after the circumstances mentioned transpired.

Plaintiffs also contend that, based upon Roberts’ failure to perform, they were entitled to rescind the contract. The failure claimed relates to an alleged guaranty of Roberts to have- a note of $4,250, executed by plaintiffs, in favor of Mrs. Retta J. Pemberton secured by a second mortgage on the farm, which is the subject of the contract of sale between Roberts and the Coppocks.

Mrs. Pemberton is not a party to this suit and the matter of the alleged guaranty cannot be adjudicated in this cause. Much of plaintiff’s testimony is directed to this matter which is outside of the case. There is no foundation for the contention that Roberts did not comply with the terms of his contract with the Coppocks. There is not a scintilla of testimony, to show that Roberts assented to the proposition made by Coppock, or made any “settlement” with him.

The word “settlement” in this connection, as used by Roberts, appears to have meant only that he was endeavoring to make some arrangement to provide for the payment, or collection of the amount due him from the Coppocks. There was no “settlement” contemplated or necessary in order to arrive at the *262 amount due Eoberts. That was all in writing and is not contested. In short, there was no meeting of the minds of the parties, or any mutual agreement for a rescission of the contract in question.

Dr. Pemberton, on cross-examination testified in relation to Mr. Coppock giving up the place to Eoberts that—“I think Mr. Coppock decided that he couldn’t make it go.”

In order to effect a rescission of a contract by a subsequent mutual agreement, it is essential that the contract to rescind should receive the assent of both or all the parties to the original contract. Just as in the making of a contract, so in a negotiation for its abrogation or termination, there must be a meeting of the minds of the parties in respect to the proposition that it shall be canceled and also in respect to any terms or conditions upon which the rescission is to be predicated: 13 C. J., p. 601, § 624; J. P. Gentry Co. v. Margolius & Co., 110 Tenn. 669 (75 S. W. 959). The request or offer of Coppock to rescind the contract had no effect whatever upon the contract itself, or the rights and obligations of the parties to the stipulation which they had made for the simple reason that the offer was not accepted, except it might be said that by making the proposition to be released from the contract, or for a mutual rescission of the same, Coppock assumed the validity of the contract at that time: 13 C. J., p. 600, § 621; O’Donnell v. Brand, 85 Wis. 97 (55 N. W. 154); Parks v. Elmore, 59 Wash. 584 (110 Pac. 381); Chadbourne v. Davis, 9 Colo. 581 (13 Pac. 721); A. Westman Merc. Co. v. Park, 2 Colo. App. 545 (31 Pac. 945); Whiting Foundry Equip. Co. v. Hirsch, 121 Ill. App. 373; Flynn v. Finch, 137 Iowa, 378 (114 N. W. 1058); Watson v. E. E. Naugle Tie Co., 159 *263 Midi. 174 (123 N. W. 589); Fripp v. Fripp, Rice Eq. (S. C.) 94.

Roberts could not have availed himself of a complete remedy in the law action which the plaintiffs commenced. The fact that he could have obtained some relief therein would not preclude him from obtaining complete relief in a court of equity. His legal remedy, in respect to the final relief and also the mode of securing it, would not have been as efficient as the remedy which he sought from a court of equity under Section 390, Or. L., and which such a court, under the circumstances of this case, could grant.

As said by Mr. Justice Harris in Pearson v. Richards, 106 Or. 79 (211 Pac. 167), at page 93 of the Report:

“The fact that a party can avail himself of a remedy in a court of law will not preclude him from obtaining relief in a court of equity unless the legal remedy in respect to the final relief and the mode of securing it, is as efficient as the remedy which a court of equity can afford under the same circumstances: South Portland Lumber Co. v. Munger, 36 Or. 457, 473 (54 Pac. 815, 60 Pac. 5); Hall v. Dunn, 52 Or. 475, 479 (97 Pac. 811, 25 L. R. A. (N. S.) 193); Butson v. Misz, 81 Or. 607, 613 (160 Pac. 530).”

The plaintiffs object to the provision in the decree requiring them to execute a new contract and which provides for paying interest annually upon $14,250. This, however, is not the case, as provision is made in the decree for a credit on the contract of $4,250 as of the date of November 22, 1921. This was on account of the note given by the Coppocks to Dr. Pemberton, which Roberts credited on the purchase price of the farm.

*264 Plaintiffs also suggest that they should be required to pay interest to the government on the $10,000 loan. Whenever the plaintiffs pay any part of the $10,000 loan to the government, that should be credited to them by Roberts. As yet they have paid no part of the loan, neither have they assumed payment thereof, although doubtless it was contemplated that the Cop-pocks would assume the $10,000 mortgage.

This cause was tried by the late Judge Bingham in his usual careful and painstaking manner. The decree is right and is affirmed. Affirmed.
