delivered the opinion of the Court:

The grounds advanced in the bill of review as evidencing the invalidity of the decrees complained of in this case are these: (1) That the complainants in the proceedings for partition had no present estate in the property which could be the subject of partition; (2) That, under the will of her husband, the appellant was the life tenant in possession of the whole of the said property for life in her own right, and the complainant had simply a remainder; (3) That there was no estate in common, joint tenancy or coparcenary existing between the complainants and the appellant which could be the subject of partition, and that, therefore, as it is claimed, the court was without jurisdiction to decree a partition; (4) That the appellant having, in the first instance, set up an exclusive right and title in herself, the court of equity was without authority to try that title, and was thereupon ousted of its jurisdiction, and had no right to proceed thereafter. Three of these propositions, as is apparent, present the question of the validity of the will.of Charles C. Smith as an effective instrument to convey real estate; for the exclusive right and title depended upon by the appellant are only given, if at all, by that will. If *352that will was ineffectual to dispose of realty, then the allegation of the original bill of complaint that Smith had died intestate, is true so far as concerns his real estate. And the fourth proposition raises the question of the power of a court of equity to proceed in a suit for partition, when the answer denies the existence of the community of title which is set up in the bill of complaint as the basis of the suit, and on the contrary claims exclusive right and title in the defendant, or in one or more of several defendants.

It is also urged in the appeal before us that, even if the sale should not be vacated as to the purchaser Winslow, the fund realized from it should be held by the trustees as a trust fund for the exclusive benefit of the appellant for the term of her life, inasmuch as she was entitled to a life estate in the property.

It is not apparent how the question of the validity of the will of Charles C. Smith, as a conveyance of real estate, can be passed upon under this bill of review; nor is it apparent how it can be determined under it that the appellant was the sole owner of the property for life, or that the complainants in the original bill had no present right or title which would entitle them to partition. All these questions may have been passed upon in the original suit; and we must assume that they were, since they were all distinctly put in issue, and no doubt were the subject of testimony in that cause. No part of that testimony appears here, and could not well have been introduced under a mere bill of review. The right of the complainants in that suit to partition depended in great measure upon the adjudication of these questions; and if they were not adjudicated correctly, which we can not assume, that would have been only error, to be remedied, if at all, by appeal.

The question in the case — and it is the question to which counsel have very properly addressed their arguments — is that of the jurisdiction of the court of equity to proceed in the suit for partition after the averment in the answer of *353the present appellant that she claimed the whole life interest for herself exclusively, and that, the complainants had no present estate in the property entitling them to partition. For if the jurisdiction was thereupon ousted, it would seem necessarily to follow that all the subsequent proceedings were null and void. But if, on the other hand, the jurisdiction was not thereby ousted and the court of equity had the right to examine into the issues raised and to determine their validity or sufficiency, then, of course, the subsequent proceedings would, at most, be only erroneous, and not void. As no appeal was taken in the case, we are justified in assuming that the court of equity examined all the issues raised, and upon the testimony correctly decided against the claims of the present appellant. And it only remains for us to ascertain whether, in our opinion, it had the jurisdiction so to do.

■ That the mere suggestion or claim of adverse title in an .answer is of itself sufficient to oust the jurisdiction of a court of equity in a partition suit, even though the claim be spurious and the suggestion be without foundation in fact .or in truth, is a proposition that we must regard as wholly inadmissible. It is not consonant with reason, and it is not supported by any authority.

The general rule, it is very true, is well settled that questions of title will not be tried in a suit for partition, and that, where land appears to be held adversely to a complainant, who seeks partition of it, he must establish his title by proceedings at common law before equity will proceed to entertain his suit for partition. And in courts of equity when a controversy over a title is developed in a suit for partition, it is the usual course either to dismiss the bill without prejudice to the right of the complainant to renew it after he has established his title at law, or, more frequently, perhaps, to hold the cause for a reasonable time until action at law can have been had, after which the court of equity will proceed with the cause. But the very statement of *354the rule shows that there must be a question of title to be tried before the court of equity will suspend its action; and the mere averment of a defendant in his answer adverse to the complainant’s right does not make a question of title although it may lay the foundation for it. Proof is required to show that the claim of title is fair and reasonable, and not a mere sham intended to delay and embarrass the complainant, and while the court of equity may not decide a bona fide claim of title, when it has been raised, it is entitled to satisfy itself that the claim is made bona fide and is such as would, if supported by sufficient evidence, be a good and valid claim. If a defendant, sued in a partition suit, sets up a claim of exclusive right in himself by adverse possession, and he shows that such adverse possession has continued only for eighteen years, when the statute requires an adverse possession of twenty years to give title; or if a defendant avers exclusive right in himself by virtue of an instrument of writing which on its face utterly fails to show any such right, as, for example, in the case of a will attested only by two witnesses when the law peremptorily requires attestation by at least three witnesses in order to make such will valid as to real estate; assuredly such allegation of adverse right can not avail the party making it, since almost in the same breath he alleges the right and shows that it has no existence in fact and no just foundation in law.

It is not for the parties to a suit, but for the court to determine the question of the jurisdiction of the latter. It is proper and often necessary for parties to raise the question of jurisdiction if they would avail themselves of any right to accrue to themselves therefrom; but to raise the question is not to determine it. Otherwise, every demurrer interposed on the ground that a complainant has failed to state a cause for equitable cognizance in his bill of complaint would be sufficient to oust the jurisdiction. Moreover, the practice which we believe has now become the prevailing practice in courts of equity, not to dismiss a bill of complaint *355when a bona fide question of title has been made, but to hold the cause for a reasonable time to allow opportunity for the determination of the question in a court of common law and thereafter to proceed with the suit for partition as the circumstances may warrant, is wholly inconsistent with the theory that the jurisdiction is ousted by an allegation of adverse title in a defendant. The utmost that can reasonably be said in that regard is that the exercise of the jurisdiction is suspended, not that the jurisdiction is absolutely ousted, when a legitimate question of title is made to appear.

If authority be needed in support of propositions of law so elementary and fundamental, authority is not wanting. See Willard v. Willard, 145 U. S. 116; McCall v. Carpenter, 18 How. 297; Parker v. Kane, 22 How. 1, 17; Weston v. Stoddard, 137 N. Y. 119; Marshal v. Crehore, 13 Met. 464; Nash v. Simpson, 78 Me. 142; Barnard v. Pope, 14 Mass. 434; Lloyd v. Gordon, 2 H. & McH. 254, 260; Tabler v. Wiseman, 2 Ohio St. 208; Overton v. Woolfolk, 6 Dana (Ky.) 374; Howey v. Goings, 13 Ill. 95, 108; Martin v. Walker, 58 Cal. 590.

Some of these cases, it is true, were decided under special statutes or special provisions of codes; but in each and all of them it was held or assumed as unquestionable law that a court of equity, wherein partition was sought, had, under the general principles of equity, the right to examine at least prima facie into the sufficiency of exclusive titles set up in bar of partition, and either to adjudicate them finally for itself or to remit them to a court of common law for adjudication. As pointed out in the case of Weston v. Stoddard 137 N. Y. 119, already cited, the general trend of judicial authority, independent of statutes, has been in the direction of the abrogation of the rule which required issues of title raised in suits in equity for partition to be remitted to a court of common law for trial, and of the substitution in the place of it of the right of the court of equity to hear and determine all the issues raised in the cause. At all events, we must regard it as beyond reasonable question *356that it is for the court itself, and not for the parties, to determine whether there is a question of title raised which would constitute a bar to its further proceeding. Having general jurisdiction of the subject matter as stated in the bill of complaint, it can not lose that jurisdiction by reason of objection to its exercise made by the defendant. The sufficiency of such objection, even if the objection calls in question the jurisdiction of the court, it is for the court itself to decide in the first instance, with the right to the defendant to have the decision reviewed on appeal. The case would be very different where the court was without jurisdiction from the beginning.

We conclude, therefore, that the court was not without jurisdiction to.render the decree which it rendered in this cause, whether the decree was in itself correct or erroneous; and that the bill of review, based upon the assumption of such want of jurisdiction, was rightly dismissed.

We do not mean, however, that anything that we have said here should be taken as precluding the appellant from establishing her rights, whatever they are, as against the fund in the hands of the trustees and under the control of the court. It is urged upon us by counsel for the appellant that “the decree of sale, being erroneous (as it is alleged), should be set aside, if not as to the purchaser, at all events as to the remaining appellees, and that the fund should be held as a trust fund for the appellant during her natural life.” But it is very clear that nothing of this kind can be done under a bill of review. The question is not whether the decree for sale was erroneous, but whether it was within the jurisdiction of the court to render it; and this question we have decided in the affirmative. If the decree was merely erroneous, and not. void for want of jurisdiction, it could and would have been corrected on appeal. But no appeal was taken.

The alternative remedy against the fund which the appellant seeks she can have in the original suit, to the extent to *357which she may be entitled, as long as the fund remains undisposed of and under the control of the court. It would seem that she is at least entitled to her dower interest. But the extent of that interest and the mode in which it should be secured to her, it is not for us here to prejudge. That question is still open to her in the court below in the original suit. At all .events it is not before us, and it is not competent for us to pass upon it at this time.

The decree of the Supreme Court of the District of Columbia dismissing the bill of review must be affirmed, with costs. And it is so ordered.
