Complainant insists that her demurrer should have been sustained: First. Because the decree of divorce is void, the district court of Jackson county not having jurisdiction, so as to hear, try and determine the case; and, second, That whatever effect the mortgage and contract referred to in said answer, might otherwise have, they are void, and have no effect: 1. Because they were made between husband and wife; and, 2. For a want of consideration. Other points are made, to which we may refer, but the foregoing embrace substantially, the main positions assumed by appellant. We shall notice them, as far as necessary, in the inverse order of their statement.
Is the mortgage and contract void for -want of consideration ? Under the Code, all contracts in writing import a consideration in the same manner as sealed instruments did before its passage. Section 975. It is claimed, however, that these instruments show upon their face a want of consideration. The argument is, that by the decree of October, 1853, the husband was bound to pay alimony to the same amount, as provided ¿for in the mortgage; that the decree was a lien upon all the land of the husband; *51■ and that the giving of the mortgage could,- therefore, give the wife no additional advantage'.
The essence and requisite of every consideration is,that it should create some benefit to the party promising, or some trouble, prejudice, or inconvenience to the party to whom the promise is made. Whenever, therefore, any injury to the one party, or any benefit to the other, springs from a consideration, it is sufficient to support a contract. Each party to a contract may, ordinarily, exercise his own discretion, as to the adequacy of the consideration ;. and if the agreement be made bona fide, it matters not how insignificant the benefit may apparently be to the promissor, or how slight the inconvenience or damage appear to be to the promisee, provided it be susceptible of legal estimation. Story on Contracts, section 431. Of course, however, if the inadequacy is so gross as to create a presumption of fraud, the contract founded thereon would not be enforced. But, even then, it is the fraud which is thereby indicated, and not the inadequacy of consideration, which invalidates the contract.
In this case, ir, seems to us, that the consideration does affirmatively appear, and is sufficiently adequate. In the first place, the husband undertook to pay the alimony in quarterly payments, instead of each week; and while he undertook to pay no more, yet he undertook and obligated himself to pay it in a different manner. We can avoII conceive, that if this Avould not resultan creating a trouble or inconvenience to the husband, it might create a benefit to the complainant, in that she Avould receive her anoney in larger sums, instead of a small pittance each Aveek. Then, again, by the decree, he was only bound to pay the costs of the proceeding for alimony, taxed at three dollars, whereas, by the settlement, he "was to pay the costs and charges in the prosecution of said claim; The charges ■here referred to mean, of course, more than the mere costs, and Ave suppose them to include attorney’s fees. If so, the consideration is shown. But .more than this, these promises were made upon a settlement of the difficulties *52.■ existing between these parties. There was a decree for divorce and for alimony, from which either party could appeal, or to set aside which motions might then have been made in the district court. As to these suits, the parties made a compromise and this settlement. As such, in the absence of fraud, so far as relates to the consideration, it should be sustained. Story on Contracts, section 4990, a.
¥e come then to the inquiry, whether the release and contract is void, for being made between husband and wife. In an equitable view, it 'seems to us, that the circumstances disclosed in the answer of respondent, are strongly opposed to the relief sought by complainant. It will be observed, that she filed her petition for alimony in September, 1853, which was within about six months from the time of the rendition of the decree for divorce. The -year within which she, by law, was allowed to appeal, had not then expired, nor had the time expired within which she might, under section 1835 of the Code, have moved to set aside the default entered against her. She then had notice of the decree, for her petition refers to, and is in fact, based upon it. So, the mortgage and relinquishment were executed in December, 1853, and before the expiration of the year. The answer avers that the husband, during his life time, complied with the conditions contained in the mortgage, by paying the amount thereby secured, and that his executor has, in like manner, complied since his death. The husband died in.1855, and then, for the first time, the decree of divorce is attacked, and an effort made to avoid the settlement made two years before, in his life time. Under such circumstances, it seems to us, that the equities are strongly in favor of respondent, and that nothing less than a strong and imperative rule of law, would justify us in disturbing a decree upon which the parties have freely and willingly acted, or in interfering with an agreement and settlement, made for the purpose of compromising their unhappy and unfortunate difficulties. Is there any such rule ? for if there is, it should be followed, whatever the consequences. The principles *53of the common law apply to declare contracts made between husband and wife, after marriage, a mere nullity, for there is deemed to be a positive incapacity in each, to contract with the other. And while courts of equity recognize this rule, they will, and do, under particular circumstances, give full effect and validity to such contracts. Story’s Eq. Jur., sec. 1372; 1 Fonb. Eq., B. 1, ch. 2, sec. 6; Bradish v. Gibbs, 3 Johns. Ch., 523.
In McCrory v. Foster, 1 Iowa, 271, these principles were recognized, and it is there said, that courts of equity will, in such cases, guard with jealous care the rights of the wife; the husband will be held to the strictest fairness and integrity ; and the wife will not be deprived of her property, by any gift or transfer procured by fraud, circumvention, or undue, or improper influence. And while policy would dictate in such cases, that a trustee should be appointed, to protect and guard the interests of the wife, yet if none should be appointed, we know of no rule which declares such gifts or transfers void, in the absence of fraud or unfair dealing. If it be claimed that these rules have no application or place, in contracts or agreements of the character relied upon by respondent, and that such an agreement is void, by the rules of equity jurisprudence, we will view the question in another aspect. Our law recognizes the right of the wife to hold and control property in her own name. The obligations resulting from this relation, are by no means designed by the Code, to be ■weakened ; and yet, it is manifestly true, that the existence of the wife is not now, so completely as formerly, merged into that of the husband. Under certain circumstances, she may transact business in her own name; she may have a separate property, which she can hold exempt from the husband’s debts ; her personal property does not vest, as of course, in the husband; she may make a valid contract which purports to bind herself only; she may convey her interest in real estate in the same manner as other persons ; may act as executor independent of her husband ; and, finally, may receive grants or gifts of prop*54erty from her husband, ■withouttheintervention of trustees. Code, sections 1192, 1207, 1304, 1447, 1453.
Now, if by these provisions, privileges and rights are given to the wife, which she did not possess by the strict rules of the common law, what legal rule is violated, or what equitable principle infringed upon, if she is held to corresponding liability, upon contracts made during coverture? Or, to state the proposition in another form, if, under the principles ' of the common law, courts of equity did in some, and 'indeed in many instances, give full effect and validity to her contracts, why should she not be bound by her engagements, in the absence of fraud or unfair dealing, •under a statute which greatly enlarges her powers and privileges ? She can make a valid contract, which will bind herself only. This, it may bo said, has reference to contracts with third persons.. This is, perhaps, true to the extent, that if made with third persons, the same rule would govern the adjudication of her rights, which would govern contracts generally; whereas, if made with the husband, he would be held to the utmost good faith, and slight circumstances of fraud and circumvention, would be sufficient to declare it invalid.
But she is also given full power to convey her interest in real estate, in the • same manner as other persons; and can receive gifts and grants of property from her husband, withouttheintervention of trustees. If the husband, then, shall grant to her a portion of his real estate, as between them, it is good, without the intervention of trustees. There is, therefore, no rule which requires that the legal estate shall vest, or be vested, in a third person for her use. On the contrary, the statute expressly gives her the right to receive, and the husband the power to give or convey, in their own names directly — he being the grantor, and she receiving the whole estate, legal as well as equitable. If she conveys her interest in real estate to the husband, or if she shall release to him an inchoate right in his estate, for a consideration just and adequate, untainted by fraud, circumvention or improper influences, it seems to us, *55that in equity, she is bound by it. Having the power to convey her real estate, in the same manner .as other persons, no reason is perceived why she might not convoy it to her husband, and in return, or in consideration thereof, she receive from him a grant or conveyance of other property. If so, why may she not, for a money consideration, make or execute a release of her interest in his real estate?
In this case, there is nothing shown to impeach the fairness of the transaction or contract entered into on the 8th of December, 1853. It is not referred to in the bill, but is set up in the answer, and therein it is insisted to have been a fair and equitable arrangement. If so, it should be sustained. If, however, there was a want of fairness and fair dealing upon the part of the husband, it should be set aside. Such a contract may be assimilated to those made between a trustee and a cestui que trust, or principal and agent. Slight circumstances may be sufficient to justify the chancellor in declaring them invalid. They are not, however, in the absence of such showing, void.
The foregoing conclusions render it unnecessary to examine the question, whether the decree of divorce was void; as well as the further one, whether complainant can be allowed to contest its-validity, after she has voluntarily appeared in court, and, by a positive affirmative act, recognized its existence and force. Her bill for alimony was based and founded upon the fact, that her husband had filed his bill, and the prayer of it is, that the decree for a divorce may be so far modified as to give her alimony. Granting that the court decreeing the divorce had no jurisdiction over her person, and that the decree was therefore void, it is questionable, to say the least of it, whether she has not, by an appeal to the same court for alimony, based upon the proceedings which might not otherwise bind her, precluded herself from afterwards objecting to the jurisdiction. Rut as it is unnecessary, we intimate no further opinion upon this point in the case. Upon the other grounds stated, we think the decree below should be affirmed.
