It seems to be conceded that the proceedings in the probate court preliminary to the sale and conveyance of the land in controversy, by the administrator of the estate of Merritt to the grantor of the defendant, are so defective and irregular that they will not support a conveyance, and hence, that the administrator’s deed is void. If that deed is void, the legal title to an undivided half of the land was in Mrs. Clark until she conveyed to the plaintiff in 1870. The circuit court held that if the plaintiff or his agent procured the conveyance from Mrs. Clark by fraudulently representing to her that he desired it for the benefit of the grantee in the administrator’s deed, or those claiming under such grantee, and if Mrs. Clark executed the-conveyance with the intention and for the purpose of ratifying and confirming the title of those holding under the administrator’s deed, the conveyance to the plaintiff is void, and the title still remains in Mrs. Clark. We think that this is an error, and that at least the legal title passed to the plaintiff by virtue of such conveyance.
But, assuming that the plaintiff obtained his title by the fraudulent means just mentioned, is the defendant affected by that fact, and can he claim an equitable interest in the land in controversy by reason of the alleged-fraud ? We think this question has been determined by this court in the case of Onson v. Cown, 22 Wis., 329. That, also, was an action of ejectment. The defense was, that the land in controversy was school land ; that the defendant once held a certificate therefor from the state, which became forfeited for nonpayment of interest, and the land was resold to one Keyes ; that Larson, the grantor of the plaintiff, applied to Keyes to purchase the land, and stated that he desired to do so for the benefit of the defendant; and that thereupon Keyes assigned his certificate to' Larson, who paid for the land and took a patent therefor from the state. There *491bad been no previo as arrangement between Larson, and the defendant concerning the land. The answer contained a counterclaim, and demanded that the plaintiff be adjudged to convey the land to the defendant. This was held to be a good defense and counterclaim; and the facts therein stated having been proved, the plaintiff (who had notice of such facts when he took his conveyance) was compelled to convey the land, to which his grantor had thus fraudulently obtained title, to the defendant. There were some equities to be adjusted in that case which do not exist here. The principle applied in that case is thus stated in Perry on Trusts, § 172 : “ If a purchaser at auction or otherwise represents that he is purchasing or bidding for some other person, as for the debtor in a sale under an execution, or Eor the mortgagor in a sale under a foreclosure, or for the family under an executor’s or administrator's sale, and competition is thus prevented, and the sale is made on his own terms, equity will decree that such person shall be a trustee for the person for whom he represented that he was acting.”
It will be observed that conveyances thus obtained are not declared void, but are held to pass the legal estate to the grantee, but subject, in equity, to a trust in favor of him for whom the grantor professed to act, coextensive with his profession or representation in that behalf.
But it may be argued that it is quite immaterial in this case whether the conveyance to the -plaintiff be held void, or whether it be held valid to pass the legal title, with a trust ingrafted upon it in favor of the defendant, inasmuch as, in either case, the plaintiff must fail in his action; and hence¡ that the judgment should not be reversed because the court erred' in the instruction that the conveyance was void if obtained by means of the fraudulent representations stated in the charge. A little reflection will satisfy the mind that the argument is unsound. The error is not immaterial. “Were the conveyance to plaintiff void in the contingency mentioned, the question of the existence of such contingency would be one of fact for the j ury to *492determine, and would doubtless be available to tbe defendant, as a defense, under the pleadings. To prove that tbe conveyance under which the plaintiff claims title is void, is merely one method of proving that the title to the land in controversy is in some third party. This is strictly a legal defense, is admissible under the general denial, and, when proved, defeats the action.
But the conveyance being a valid one to pass the legal title to the plaintiff, the defense that it enures to the benefit of the defendant is purely an equitable defense, in that, if established, it results in the declaration and enforcement of a trust, which is a matter cognizable in courts of equity alone. The issue upon such a defense, if affirmative relief is demanded by the defendant, is triable by the court, unless the court shall order the same to be tried by a jury, as it may order questions of fact to be so tried in other equity cases, in its discretion. Tay. Stats., 1494, § 6. But in such case the verdict does not have the same force and effect as verdicts in actions at law. It is not binding upon the judgment of the court, and if unsatisfactory and against the weight of testimony, the court may set it aside and order a new trial of the issue, or may vacate the order awarding a jury trial, and decide the issue without the intervention of a jury. Jackman's Appeal, 26 Wis., 104. That the court should retain this plenary control over verdicts in equity cases where jury trials are awarded, is a material and valuable right of the parties. Hence, an error which results in depriving the court of that power, must necessarily be a material error.
The counsel for the defendant, evidently perceiving the difficulty, argue in their brief that in cases of fraud, equity and law have concurrent jurisdiction. In some cases of fraud this is true, but it is not true as a general proposition. We apprehend that the learned counsel would be at a loss how to proceed, in order to procure in an action at law a declaration and enforcement of the trust which may result to their client by *493reason of the alleged fraud of the plaintiff in procuring his conveyance.
The defense, being an equitable one, to be available in an action of ejectment, must be set up in the answer, and. be accompanied by a demand for such relief as the defendant supposes himself entitled to. Tay. Stats., 1667, § 7 (R. S., ch. 141, sec. 7). A mere equitable defense is not sufficient. There must be a counterclaim also. The statute was doubtless intended to avoid the difficulty suggested by Hand, J., in Dewey v. Hoag, 15 Barb., 365. He says: “I do not understand there is any equitable defense, simply as a defense, in an action of ejectment. The effect of that might be to keep the legal title and possession forever separate.” (p. 869.)
The court erred, therefore, in admitting, under the pleadings, testimony tending to show that the plaintiff procured his conveyance by representing to Mrs. Clark, his grantor, that he desired it for the benefit of the purchaser at the administrator’s sale, or those claiming under him. There must be a new trial; but, under the circumstances, the defendant should be permitted, on such terms as the circuit court shall deem just, to amend his answer só as to interpose such equitable defense and counterclaim.
The case of Kent v. Agard, 24 Wis., 378, does not conflict with the foregoing views. It was there held that in an action of ejectment a party may show, without specially pleading the fact, that a conveyance, absolute on its face, is a mortgage, and that the debt which it was given to secure has been paid. There is no doubt of the correctness of that decision; and it is perfectly clear that it is not applicable to this case.
