delivered the opinion of the Court:
In July, 1844, Hubbard and Davis filed their bill in chancery against Egan, Blanchard and others, for the purpose of subjecting certain lands therein described to the payment of certain judgments obtained by Hubbard and Davis against Egan in the Municipal Court of Chicago. A large quantity of lands was described in said bill, and there were numerous defendants, besides Blanchard, who were distinctly charged with holding fraudulent titles under Egan. Blanchard, at that time, claimed title to a part of the lands described in the bill by virtue of a sale under a judgment against Egan in favor of one Church, rendered in 1837, at the same term of the same court at which Hubbard and Davis obtained their judgments. At this sale Blanchard, who was the assignee of the judgment, became the purchaser, and in 1840 received a sheriff’s deed. Subsequently he conveyed to Thomson, the complainant in this case. The only distinct allegation in the above mentioned bill of Hubbard and Davis affecting the title of Blanchard, who had not then conveyed to Thomson, was, that at the time when Hubbard and Davis obtained their judgments against Egan, and at the close of the term when said judgments were obtained, Egan was the owner of the lands described in their bill, which included the land bought by Blanchard. The bill, however, charges that Blanchard claims some right or title to a part of said lands in some way through Egan, and that he knew of complainant’s superior equity in said lands when he acquired his interest therein, and asks that he may set forth what title or claim he has. Blanchard did not answer the bill, and it was taken pro confesso as to him. In 1846 the court pronounced a decree ordering a sale of the lands to pay the Hubbard and Davis judgments. Under this *336decree the lands Avere sold in 1847, and the sale and deed having been subsequently reported to the court, they Avere approved, and a final order Avas pronounced confirming title in the purchasers, and decreeing that the deed of the commissioner be considered as a conveyance of the rights and interests of the defendants and each of them in the premises. This title has passed to the defendants in this proceeding, and the bill in this case Avas filed to set it aside as a cloud upon the title of complainant claiming under Blanchard, and being in possession. The superior court decreed in favor of the defendants and dismissed the bill. The complainant appealed.
It is urged by counsel for appellant that the decree pro confesso in the former suit, only established against him the allegations of the bill, and as there Avas no specific allegation to the effect that the title claimed by Blanchard Avas, for any reason, subject to the judgments in favor of Hubbard and Davis against Egan, the default of Blanchard admitted nothing to his prejudice, and the court had no right to decree the sale of Avhatever title he might have. It is insisted, in other Avords, that the bill did not bring Blanchard’s title before the court for adjudication, and that in attempting to adjudicate upon it, the court was exceeding its jurisdiction as to the subject matter, and its decree was Amid. On the first argument of this case Ave adopted this view, but a rehearing having been aAvarded, we have given the case further consideration, and are satisfied our first opinion was erroneous.
The difficulty in the reasoning of appellant’s counsel is, that they confound, and are obliged to confound, for the purposes of their argument, the difference between a decree merely erroneous and one void for want of jurisdiction. It may be conceded, for the purposes of this case, that the court should not, on the allegations in the bill of Hubbard and Davis, haArn decreed the sale of Blanchard’s title, though he was in default. It may be conceded that Blanchard might, in proper time, have brought that decree to this court and have *337hud it reversed. But, .nevertheless, it was not, as to Blandíanlas title, a void decree. The court had jurisdiction over him by due service of process, and the subject matter of the bill was one of ordinary chancery cognizance. The bill was filed to subject certain lands situate in the county where the court was held to the payment of certain judgments. Blanchard was in court by service, the land was under the jurisdiction of the court, the bill brought the question of its sale before the court for adjudication, and the decree which the court was asked to make, and did made, in regard to it, was but an exercise of the plainest of chancery powers. The power may have been improperly exercised. Neither the bill nor the proof may have justified the decree. Nevertheless, the naked power or jurisdiction to make it can not be denied. The bill alleged that the complainants had obtained certain judgments against Egan, that the lands in question belonged to him at the date of the judgments and at the expiration of the term when they were rendered. This allegation showed that the judgments had been a lien on the lands, and unless it should be made to appear that this lien was subject to some other paramount lien or equity, the land ought to be sold for their payment. Blanchard might have demurred to the bill on the ground that, so far as it related to him, there was no necessity shown by it for coming into a court of chancery. It disclosed no reason why the complainants had not sold under execution, since it did not allege such a title or claim of title in Blanchard as Avould have interfered with such sale, or haA'e clouded the title of the purchaser. It did not eAmn allege, in general terms, that Blanchard claimed a paramount title. He might, therefore, have demurred, and asked that, as to him, the bill be dismissed. Or he might have answered and have shown his superior equity in the lands, if he had any. One of these tAAro things he Avas bound to do, if he desired to protect his title. Not doing either, the court had the poAver to order the sale of the land, including his interest therein, although it Avould probably have declined to do so, if he had shown, by a demurrer, *338that there was ample remedy at law for the complainants, so far as concerned him.
Deficient as the bill may have been in allegations showing the necessity of bringing Blanchard into court, the purpose for which he was brought there was nevertheless apparent. The bill alleged that he claimed an interest in the lands, but that he had notice, when he acquired it, of complainant’s superior equity. He was thus informed that the bill sought, not only to have'the lands sold, but also to have his interest in them sold, unless he should show, by his answer, that he had such an interest as would make their sale unjust. The allegations of the bill were thus sufficient to bring before the court the subject matter upon which it decreed, to wit: the sale of the lands in payment of the complainants’ judgments.
Counsel for appellant cite numerous authorities for the purpose of showing that the decree was not an estoppel, so far as concerns the question whether the equity of Davis and Hubbard was superior to the title of Blanchard, because that question was not distinctly put in issue by the pleadings. But our decision is not based upon any ground of estoppel. The authorities' cited relate to cases in which the attempt has been made to conclude the parties to a suit as to some matter of fact, upon the ground that the fact has been determined in some former litigation between the same parties. We may concede that, in any suit which may arise, Blanchard should not be estopped from proving, as a matter of fact, that he had, when that decree was rendered, the superior instead of the inferior equity. His grantee may prove it in this case, but the difficulty is, it avails nothing when it is proved, because his title, whether superior or inferior, was sold under the decree. The question is not one of estoppel as to any facts found by the decree, but simply as to the effect of a sale ordered by the decree to be made. This question brings us back to the starting point—the naked question of jurisdiction over the person and the subject matter. On that we can come to but one conclusion.
*339The question is really not an open one in this court. In Finch v. Martin, 19 Ill. 111, several persons were made defendants, with the general averment that “ they claim or pretend to have some title or interest in the premises, which is fraudulent and void. ” There was a demurrer to the bill, and this court held that the allegation was sufficient, saying the defendants were bound to disclose their title, if they had any, and if they had none, they should disclaim. Prior to that decision, it had been the common practice, in bills filed for the purpose of having land sold, to make persons defendants, by a general allegation of this character, and ask that they be required to disclose their titles. This was constantly done in bills to foreclose mortgages and bills to subject lands to the payment of judgments, for the purpose of clearing the title and cutting off rights of redemption. This case in 19th 111. approved the practice, and it has now become a rule of property, under that decision, which it would be very wrong to shake. In that case the court held such a general allegation was good upon demurrer. In the bill filed by Hubbard and Davis, the positive allegation that the claim set up by Blanchard was “ fraudulent and void” was not made, as it was in the case in 19th 111. and in this opinion we have been disposed to concede that that bill was demurrable, on the ground that the inferiority of Blanchard’s title to the equity of the complainants was only argumentatively shown, and it did not appear, as against Blanchard, why the complainants’ remedy was not complete at law. But the case in 19th 111. is directly in point, as showing that where a party is brought into court for the purpose of permitting him to set up his title to real estate in which complainants claim an equity, he must appear and defend, if he has interests which he desires to protect. If the allegations of the bill are defective, or the relief asked can be had at law, he may, of course, demur; but if he fail to appear at all, and the court decrees the sale of his land, he can not be permitted to say the decree was void merely because the allegations as to his title were not positive or specific. "When the decree is *340collaterally assailed, it is sufficient to know tliat the defendants were in court by service or appearance; that the decree was one which a court of equity has power to makp, and that the subject matter upon which it operated was brought by the bill before the court for adjudication.
If in court by due service, as party to a bill praying a sale of lands in payment of certain judgments, on the ground that-the lands belonged to the judgment debtor, and if the bill showed upon its face that he claimed an interest which the complainant sought to subject to sale because of its inferior equity, and was made a party that he might disclose his interest, then the decree, however erroneous, is not void, and a sale under its authority is not a nullity.
The decree of the superior court dismissing the bill must be affirmed.
Decree affirmed.
