The opinion of the court was delivered by
Hoyt, J.This was an action of ejectment. In his complaint plaintiff claimed title in fee without in any way deraigning his title. Defendant for answer denied generally, and further pleaded that he held the premises in question by virtue of a sale thereof under a decree of foreclosure of a certain mortgage made by one Sheil, who at the time of the execution of said mortgage and of the sale thereunder, was the owner in fee.
Upon the trial, plaintiff introduced certain deeds showing a chain of title ending in Sheil, the maker of said mortgage, and also a trust deed made by said Sheil to him soon after the sale in said foreclosure proceedings, and a quitclaim deed from said Sheil made long after, and just before the commencement of this suit. Defendant, to meet the prima■ facie case thus presented, put in evidence the record and proceedings in said foreclosure suit, to show title, and also proved certain acts and statements of said Sheil, done and made at and after the sale under said decree of foreclosure, which in equity would estop said Sheil from afterwards asserting title adverse to said sale.
Plaintiff in his argument here practically concedes that, if said record and proceedings were properly in evidence, they constituted a good defense. He likewise practically concedes, that the acts and declarations of said Sheil, proved as aforesaid, were sufficient, if rightfully in the case, to constitute an estoppel in pais, and thus a perfect defense. Plaintiff, however, objected to the introduction of the said record and proceedings on various grounds, *193and tbe main contention here bas been npon errors assigned upon exceptions to the ruling of the court below, in admitting the same in evidence against such objections. He also objected to the admission of proof tending to establish said equitable estoppel, and has duly assigned error to the action of the court thereon.
Plaintiff’s first objection to said record was that the subpoena to bring in the defendant to answer the complaint was served by the sheriff of the county and not by the United States marshal, or his deputy, or by any person appointed by the court to make such service, and cites § 2 of the civil practice act, as amended by the laws of 1871. We think, however, that the general provisions of said section was controlled by the special provisions of § 66 of the same act as thus amended; and that by virtue of said last-named section the sheriff was authorized to make the service in question. Nor can we agree with the further contention of the plaintiff that even although the sheriff was authorized to make the service, his certificate as to the fact of such service was not proof thereof, as such facts should have been shown by affidavit. We think that under said section the sheriff was not only-authorized to make such service, but also that the return thereof could be by certificate as in other cases. The service and proof thereof were sufficient, and the court obtained jurisdiction, and having jurisdiction of the subject-matter and of the parties, most of the further objections urged by plaintiff were clearly mere irregularities, which could only be taken advantage of by appeal. See Freeman on Judgments (3d ed.), § 126; Peck v. Strauss, 33 Cal. 678.
Plaintiff further urges that there was such a departure from the terms of the decree, and from the course and practice of the court, in making the sale under said decree, as to make such sale void. But we think there were no such errors as would oust the court of jurisdiction; and this being’so, it follows that the order confirming the sale con-*194eluded inquiry into the irregularities attending the same, if any there were. See Borer on Judicial Sales, §§ 113, 115; Voorhees v. Jackson, 10 Pet. 449. The record and proceedings were properly admitted in evidence, and the errors assigned thereon are not well taken.
The ground of the plaintiff’s objection to the proof of the equitable estoppel was that the defendant could not be permitted to introduce evidence of this kind without having pleaded it in his answer, and cites several cases holding that in an action at law equitable defenses must be set up in the answer. This is perhaps true as a general proposition, and under the circumstances of the cases cited, it was doubtless correctly so ruled.
Had the plaintiff in this action set out fully his chain of title, so that it would have appeared that he claimed under said Sheil, it might have been necessary for defendant, in order that he might show acts of said Sheil, to have set out the same in his answer. But when, as in this case, a defendant is not at all advised as to the source of the plaintiff’s title, he can content himself with a general denial, and thereunder introduce any legal evidence that tends to defeat the title of the plaintiff, as shown by his proofs. Anyotherrule would work great hardship to a defendant, while the enforcement of said rule cannot work hardship to a plaintiff, as he can, if be so desires, so shape his complaint as to compel defendant to fully disclose his defense in his answer. Said rule is not only in accord with our ideas of propriety and justice, but is also abundantly sustained by the authorities. Kirk v. Hamilton, 102 U. S. 68, was a case of ejectment like the one at bar, and was brought in a court where the distinction between legal and equitable defenses is more clearly defined than in this state; yet in that case evidence of an equitable estoppel, much like the one proved in this case, was admitted under the plea of not guilty, and the action of said court in thus ruling was sustained by the supreme court of the United States in an exhaustive opin*195ion by Justice Hablan concurred in by tbe entire court. See also Mather v. Hutchinson, 25 Wis. 27.
Tbe court below properly admitted proof of tbe equitable estoppel, and tbe record and proceedings in tbe foreclosure case were also properly in evidence, and as one constituted a complete legal defense, and tbe other estopped plaintiff from asserting any title that be might have bad, tbe court bad double warrant for directing a verdict for tbe defendant and entering judgment thereon; and its action in so doing must be affirmed, and it is so ordered.
