delivered the opinion of the Court.
The case of Dennis vs Warder, &c., (3 B. Monroe, 173,) in which a judgment in ejectment in favor of Warder, the plaintiff, was reversed by this Court, is referred fo'for á statement .of the’preliminary facts of the present case, and of the nature-of Warder’s claim. It now appears, that before the -reversal of that judgment, Warder entered'upon the'possession of the land -in contest, of. which, he claimed one fifth'as the share of his wife in the estate descended from her father, Moses Moss;, and that upon a bill filed by him against the devisees of Nelly Moss,.who had purchased the same land from the executor of said Moses, he obtained' a decree setting apart one fifth .of the tract-to. hini by m'etes and bounds, and also for rents, against the devisees of Nelly Moss, and a *515purchaser from them. To review and reverse this decree, and to obtain a release of the title of Warder and wife, are the principal objects of the present consolidated suits, in which by the original, and amended, and cross bills, all the devisees and the purchaser above referred to unite. .
Among other errors assigned in the bill of review, it is ■alledged that Mrs. Warder, whose interest Warder claims,should have been made a party, but was. not, and that-upon the pleadings and evidence in the case, he was entitled. tó no. decree. The subsequent reversal of the judgment in ejectment, and the equity growing out of the fact that Warder and wife stood by and permitted the sale by the executor, to Nelly Moss, and delivered the possession to her and received the benefit of the sale'in the occupation of another tract of land purchased with a part of the proceeds, and conveyed to Kendall Moss, for the separate use of Mrs. Warder, are specifically set up and relied upon. And the case is made out, that while Mrs, Warder enjoys the benefit of the land purchased for her by her share in the proceeds of the tract now in contest, her husband, from whom, on account of ill treatment, she has separated, holds one fifth of the land in contest as her interest therein, by descent from her father, and-in opposition to the sale of the'latter tract by the executor, in which he and his wife had long acquiesced, and of which they had both had, and the wife still has the benefir. And it also appears that by the decree sought to be reviewed, he obtained rents for the tract now in dispute, for-the same years during'which he occupied the other tract, after having expelled his wife therefrom..
Mrs. Warder, by her answer in the present case, filed without oath or privy examination, professes a willingness to confirm the sale by the executor, of the land now in contest, fearing that if that sale be defeated, the settlement of the other tract upon her and her children, may be endangered, or at least that they may be madeiiable to damages. But Warder resists the equity set up in the bill, on the'ground that his acquiescence in the sale, by the executor, of the land now in contest, was caused by a mistake under which all parties labored, that this land, *516which'was- acquired after the date of the will of MoseuMoss, was-subject-to the power'of sale therein conferred-on the executor.
Decree of the Chancellor. M complainant asking equity-will be required' .first todO equity.The Chancellor was of opinion that Warder was nob estopped from-asserting title to-the land; because of the common mistake with regard to the power of the execu-tor, and'gave relief no farther than by reducing the amount of rents as-formerly decreed, and perpetually enjoining the collection of the excess-.-
It may be true that there was- a common mistake or delusion among all parties interested, with regard to thepower of'the executor to sell the land- in question. But if the fact that Warder’s acquiescence in the sale under-this common delusion; should prevent a decree against him for a title; w-e are inclined to t.hink this acquiescence, coupled-with the-fact that the'proceeds of the sale went to the benefit of himself and' his wife, through whom alone he claims title, should preelude him from all claim to the aid of a-Court of Equity in establishing his claim, or any right growing out of it in opposition to the sale, unless it were against persons who had deceived him. And even if his-claim-were not absolutely precluded inequity, it could 6nly be entertained there upon the terms of his complying, on his part, with the-principle of equity which would require him to make compensation to the extent of the loss which he might impose by the assertion of title in opposition-to the sale which he had encouraged. He- has intimated no offer or willingness to do this-; and it seems certain that he had no equity in favor of his claim to rents from the land now in contest, for the time-during which-he-was enjoying the other tract which had been purchased with the proceeds of his and his wife’s interest in this.
The bill for a-partition and for rents, refers to and irn corporates with it the record .of the ejectment case as it existed when it was brought to this Court, and on which the Court said that Warder might be estopped in equity though not at law; and there was no suggestion either-in the suit for a division or in the ejectment case, that Warder’s acquiescence in the executor’s sale, was occa-* sioned- by ignorance or- mistake as to h-is rights. Upo» *517ihe face of his bill and exhibits, which showed all the facts adverse to his right, he was asserting a title which he could not assert in equity, and claiming relief contrary to justice and good conscience. The answers filed in that case make no objection to a division, and say nothing as to rents. But looking to the character and relative condition of the defendants, we are not satisfied that the answers should be regarded as sufficient to authorize a decree to which the complainant, on his own showing, had no right, since the consent or waiver of objection to the partition, seems to be conditional, except in the answer of the infant defendants, purporting to be filed by a guardian ad liLem, of whose appointment there is no proper evidence in the record. We are inclined to the opinion, therefore, that the original decree for partition and rents, might be reversed upon the general allegation that upon the pleadings and evidence, it is contrary to equity; and this is certainly so with regard to the decree for rents, which derives no aid from the answer.
The husband cannot, assert an interest in right of his wife in a Court of Equity, ■without making her a party.But if the decree' could not be reversed to any extent on the general assignment of error, we are of opinion that it is reversable on the ground that Mrs. Warder was not made a party. It is understood to be a rule of practice in equity, that the husband cannot, in that Court, assert an interest in right of his wife, without making her a party, if she be alive ; and an adherence to ,this rule would seem to have been peculiarly requisite in the present case, since it not only involves the appropriation to the husband of an interest claimed in right of the wife, but involves also, some hazard, if not actual injury to other-interests of the wife. Again, if the husband may defeat the executors sale in virtue and to the extent of his interest as husband in the title of his wife, it could scarcely be denied that upon the death of the husband or other termination of the marriage, the wife or her heirs, might defeat it entirely, and she ought to be bound by the divi* si,on assigning her interest to her husband, and ought,, therefore, to be a party to it. In this respect the defendants, as well as she herself, had an interest in her being a party, and had, therefore, a right to assign for error the-omission to bring her before the Court, But there arc *518other necessary parties who were not brought- before, the Court. ■One who was made a defendant's the bill on the-allegation that'he had acquired- the .interest .of some of the devisees.of Nelly Moss,-was not'served with pro* ce.ss and did not appear.'-. And ..moreover,' as the c.ornplainant.founds his claim upon the principle that the title S the entire tract descended from Moses Moss to his heirs', of whom Nelly Moss was but one,'it is obvious that her devisees and ail’claiming under her, represent but one' fifth of the title under which-the partition is claimed, arid- not'only Mrs.- Warder bu-t the three- other heirs .of Moses Moss; should have'been parties, in order; that the. question of t-itié and possession might be settled;
-The failure to máke the necessary parties m the original suit, held to be a sufficient ground of reversal on bill of review.The defendants in the decree have riot, in-their bill.of review, Telied specifically -upon the omission to make these parties defendants,.except as to-Mrs. Warder, 'But we are of opinion that the'omission to make her-a party is a sufficient' ground'of reversal, -and that for tbis'error, specifically assigned, the entire-decree should have been reversed,,and a decree rendered according to the .merits of the whole case, as disclosed in the original' suit, arid upon the subsequent bills and cross bills. .
As already intimated; we are of opinion that Warder had no equity upon the ease presented; against the'parties claiming under Nelly Moss, even if the fact of the gene-: ral mistake as to the power of the exéculor, set forth in 'his answer to-the bill of review, be taken as if alledged in-his. own bill for partition arid' re.hls, and as his-possession appears to have been wrongfully; obtained, - his bill sboúld'have bée'n dismissed,. but without prejudice,■ sofa ras the partition is'eoricerned. Whether the complainants in the'original and cross bills ar.e entitled to any further relief-than that of-.reveising the former decree and dismissing Warder’s -bill, .is a more serious .question.
■It is not shown that.Warder -was ignorant of any fact upon wh-ich’the right of himself and wife, ’or the. power of, the executor depended. He was hound to know the contents of the will.óf Moses Moss, and he should, have been advised of-its legal effect.- ' The sale of the- land was not made by-a stranger for his own benefit, and-' under assertion of title in himself, but by the executor, and *519for the benefit of the heirs or devisees of the former owner, and claiming' power to sell under the will. The heirs acquiesce in- this claim and in the sale made undent* The purchaser (one of the heirs) confiding in ' the powej: claimed and in the general acquiescence, pays a fair price which the heirs recieve, and of which the proper proportion was appropriated to the benefit of Warder and wife, and the whole or a part of that portion invested in land for the use of the wife, in which Warder for many years acquiesced. Can be when, after the separation of himself and wife, he professes to have discovered that the executor has no power to sell, defeat the sale to the extent of his interest,.on the ground that when it was made he erroneously supposed the executor had power under the will ? Who can say with absolute certainty, that he was actually in error on the subject, - or that if he had not been in error he would' have opposed the sale? Ilis acquiescence in the sale cannot be said to have been based exclusively on the erroneous supposition that the executor had power to make it, for the benefit was received directly by his 'wife, and indirectly by himself; and the arrangement by which a part of it was appropriated to the separate use of his wife, was rendered proper,by the circumstances, even if the direction of the will to that effect did not apply, and it might have been assented to by him, if he had been under no mistake. Besides, as' the-wife was entitled under the will, to other money besides the proceeds of the land, it cannot be assumed that Warder did not himself receive for his own use a-portion of the price.
Equity w¡n üot P^1™.6 , ■ one but passively, to otheTufiay out an eironeoü^oí ^¿ionaf°g to withhold the 235V 2 VVem’. 150-1The equity against him arises, from the fact' that he knew that the purchaser relied upon the title to be conveyed by the executor,'and under that reliance paid' her money, that with this knowledge-he stood by, without question-ing.the. power or asserting any opposing claim, and that he and his wife received the benefit of the sale. The Court of equity will not permit a man knowingly, though but passively, to encourage another to lay out money under an erroneous opinion of title,.and after-wards to dispute or withhold the title: Dorn vs Spencer, (7 Vesey, 235;) and in the ease of Hundsley vs Chey*520ney, (2 Vern. 150,) a tenant in tail was held bound to make good the undertaking of her son or grand-son, in a treaty and agreement of marriage, to which she was privy, (and as stated in one report to which she was a subscribing witness,) on the ground that she did not mention that she had more than a life estate; and other cases similar in principle, are there referred to. The principle of these cases is, that the party against whom the relief was granted, was guilty of bad faith in not disclosing his title when he should have done it, and in afterwards attempting to defeat the transaction which was founded upon his silence. And the question now is, whether the principle applies with full force to the case where the party against whom relief is sought, though presumed to have known the facts on which his right is founded, may also be presumed to have been in fact ignorant of his right, and whether under such circumstances, his silence at the time will so affect his conscience as in the consideration of a Court of Equity, to preclude him from asserting his right when afterwards discovered. In the cases referred to, the party acquiring, received no benefit individually, from the transaction, but may be assumed not to have been ignorant of his own right, and to have knowingly abstained from asserting it. In the present case the party did receive some benefit, but was ignorant 'of his right, and therefore, cannot be said to have knowingly concealed it; and the facts on which it was founded, were as well known to the purchaser and all others concerned, as to himself.
—But a mere failure to assert title, of which the party was ignorant at the time of sale to another, will not affect the conscience of the party thus passive and bind, hint.Upon this analysis and comparison of the cases, we are of opinion that the one now before us is distinguishable in principle, from the others referred to, on the ground that the mere failure to assert a title of which Warder was ignorant at the time, could not affect his conscience so as to bind him to the sale, although under a like ignorance, he received a part of the benefit of it, and that he is not bound now to release or convey his title, though he is bound in equity to the extent at least of the benefit received by him from the sale, to compensate for the loss which he may occasion by defeating it. If he were out of possession, the Court might not only *521refuse its aid to gain it, but might restrain him from the , ° full benefit of his'legal remedy, -until he should make compensation. But as the Court cannot decree the title from him, we do not perceive that it can deprive him of t-he possession, which if wrongfully taken under .a judgment in ejectment, afterwards reversed., may be restored on motion, by the -Court of Law, but-cahn-ot be restored by the Court of Equity, unless the title itself could be reached in that Court. And if the complainants, though out-of -possession, might come into equity to be compensated for their loss and for an account, the bill is not framed with'that view, and does not entitle them to that relief.
Hord for plaintiffs: Beatty for defendants.Upon the whole -case, therefore, the devisees of Nelly Moss, and those-claiming under them, .have not shown themselves to be -at present entitled to any relief beyond-the reversal of Warder’s decree against, them for partition and rents, and the dismissal of his bill; end their bills and cross bills, so far-as they pray for any additional relief, should have been dismissed without prejudice..
Wherefore, the decree is reversed and the cause remanded, with directions to reverse the decree .-of Warder for partition and rents, arid to dismiss his bill -without prejudice, -and also to dismiss, without prejudice, the bills and cross bills -of the other parties, so far as they pray for relief beyond the review and reversal of the decree against them.
