The CHIEF JUSTICE

delivered the opinion of the court.

It is true the record sued upon in this ease does show that defendant was not served with process, but it also shows his voluntary appearance by an attorney. If this appearance was authorized, it is as effective for the purposes of jurisdiction as an actual service of summons. When an attorney of a court of record appears in an action for one of the parties, his authority, in the absence of any proof to the contrary, will be presumed. A record which shows such an appearance will bind the party until it is proven that the attorney acted without authority.

Since the cases of Thompson v. Whitman, * and Knowles v. Gaslight and Coke Company, † it may be considered as settled in this court, that when a judgment rendered in one State is sued upon in another, the defendant may contradict the record to the extent of showing that in point of fact the court rendering the judgment did not have jurisdiction of his person. If such showing is made the action must fail, because a judgment obtained under such circumstances has uo effect outside of the State in which-it was rendered.

But if it appears on the face of the record that the court *455 did have jurisdiction, extrinsic evidence to contradict it is not admissible under a plea of mil tiel record. The office of pleading is to inform the court and the parties of the facts in issue; the court, that it may declare the law, and the parties, that they may know what to meet by their proof. Nul tiel record puts in issue only the fact of the existence of the record, and is met by the production of the record itself valid upon its face, or an exemplification duly authenticated under the act of Congress. A defence requiring evidence to contradict the record must necessarily admit that the record exists as a matter of fact, and seek relief by avoiding its effect. It should, therefore, be formally pleaded, in order that the facts upon which it is predicated may be admitted or put in issue. Under the common-law system of pleading this would be done by a speeial plea. The equivalent of such a plea is required under any system. The precise form in which the statement should be made will depend upon the practice of the court in which it is to be used, but it must be niade in some form. Defects appearing on the face of the record may be taken advantage of upon its production under a plea of nul tiel record, but those which require extrinsic evidence to make them apparent must be formally alleged before they can be proven. This we believe to be in accordance with the practice of all courts in which such defences have been allowed, and it is certainly the logical deduction from the elementar}7 principles of pleading. * In Knowles v. Gaslight and Coke Company, the issue was directly made by an averment of jurisdiction in the complaint and a denial .in the answer, and in Thompson v. Whitman by plea and replication.

It follows that, upon the pleadings in this case, judgment should have been given for the plaintiff’ after proof of the *456 record, showing as it did jurisdiction of the defendant by reason of his appearance by attorney. As both parties, however, submitted evidence without objection upon the question of the authority of the- attorney so to appear, we should have held them to a waiver of the proper pleadings to present that issue if it appeared affirmatively that this evidence had been considered and passed upon by the court below. Such, however, is not the case. Judgment- was given for the defendant upon the sole ground that it did not appear from the record or the evidence that summons had been served. This was error if the defendant had in fact voluntarily appeared. The record upon its face furnished evidence of such an appearance. The court did not find that this evidence was not in accordance with the facts.

The judgment of the Circuit Court is, therefore, reversed, and the cause remanded with instructions to award a venire de novo, and permit such amendments to the pleadings as may be necessary to present fairly for trial the real issues between the parties.

Reversed and remanded.
