Appellees brought this action against appellant to recover possession of and to quiet their title to the real estate described in the complaint. Appellant’s demurrer to the amended complaint was overruled. Appellant filed a cross-complaint in two paragraphs-, and appellees’ demurrer to same was sus*154tained. Upon leave .granted, appellant filed an amended second paragraph of cross-complaint, to which appellees’ demurrer for want of facts was sustained. Appellant refusing to plead further, judgment was rendered in favor of appellees. The rulings of the court on the demurrers are assigned as errors.
It appears from the amended complaint, that in 1886, appellant and one Isabelle Lacy were husband and wife, it being the second marriage of each; that said Isabelle was the owner of eighty acres of land in Howard county, Indiana, and that, each being of an age when no children would likely be born to them, and said Isabelle having no children and no father or mother or brother or sister living, and having raised appellee, Della Rains, they were desirous of making a marriage settlement of the respective property rights of each in case of the death of either, and for the purpose of carrying into effect such settlement appellant and Isabelle Leach, his wife, on the 11th day of August, 1886, executed a deed conveying said eighty acres of real estate to a trustee. It was set forth in said deed that the same was made for the express purpose of having the grantee convey the east half of said real estate to appellant, and the west half to Isabelle Leach, his wife, “to the intent that, when said conveyances are made, each shall accept the same in full satisfaction and discharge of any interest either has in the tract conveyed to the other by virtue of the marital relations existing between them, and it is agreed and understood that in consideration of the making of said conveyances each of the grantors hereto does release any and all interest in the tract so conveyed to the other which now or might hereafter exist on account of the marital relations of the two.” That, in accordance with said trust, the trustee, on the 11th day of August, 1886, executed a warranty deed conveying the *155east half of said eighty acres to appellant. It was recited in said deed that appellant, the grantee, should receive and accept said real estate “in lieu of any interest he has or may have in the real estate this day conveyed to Isabelle Leach, hik wife, either as her heir, or by virtue of the marital relations existing between them, under the statutes of Indiana, and the said Lewis Leach does hereby receive and accept this conveyance in lieu of and in full satisfaction of any and all claims on or interest in the real estate this day so conveyed to Isabelle Leach, his wife, that he has or may have as her heir, or by virtue of their being husband and wife: provided that she accept the tract so conveyed to her in lieu of her interest as his wife in the tract herein conveyed to him;” that appellant accepted said deed on said terms, and took and held possession of said real estate from the date of said deed, and has received the rents and profits thereof continuously until the commencement of this action. On the same day, August 11, 1886, said trustee, in accordance with said trust executed a warranty deed, conveying the west half of said eighty acres to Isabelle Leach. It was recited in said deed that “said Isabelle Leach shall receive and accept said conveyance in lieu of any intérest she has or may have by virtue of her being the wife of Lewis Leach [appellant] in the real estate this day conveyed to him,' and she does receive and accept the same in lieu of her interest in the same by virtue of her being the wife of said Lewis Leach [appellant].” Said Isabelle Leach accepted said conveyance and took and held possession of said real estate conveyed to her until when she died, intestate, the owner of said forty acres, leaving surviving her, appellant, her husband, and nephews and nieces, but^ no children or their descendants. It is clear, under the facts stated in the'amended complaint, that appel*156lant would, unless prevented by the deeds set forth, take the forty acres in controversy, under section 2651, Burns’ R. S. 1894 (2490, R.’ S. 1881), which provides that “if a husband or wife die intestate, leaving no child and no father or mother, the whole of his or her property, real and personal, shall go to the survivor.”
Appellant insists that “his right of heirship to the land in controversy is not barred by the deed he and his wife executed, conveying the eighty acres to the trustee.” It would seem clear, however, that the language that “each of the grantors does release any and all interest in the tract so conveyed to the other, which is now or might hereafter exist on account of the marital relations of the two,” was comprehensive enough to include the right to inherit as heir under the provisions of section 2651, Burns’ R. S. 1894 (2490, R. S. 1881). Heirship, under said section, depends upon the marital relations, and if that relation did not exist at the time of the death, the survivor could not inherit as heir, or otherwise. Heirship of the survivor exists, therefore, on account of the marital relation of the two at the time of the death of the other. The language of the deed made by appellant and wife to their trustee therefore was comprehensive enough to, and did, authorize the trustee to insert the release contained in the deed to appellant of any interest he might have in the forty acres in controversy as heir of his wife or by virtue of the marital relation existing between them. But we are not required to depend alone on the language of the deed to the trustee, for as the three deeds were executed at the same time and relate to the same subject-matter and were part of the same transaction, they must, therefore, be construed together. Burns v. Singer Mfg. Co., 87 Ind. 541, 547, and cases cited; Ireland v. Montgomery, 34 Ind. 174; Schmueckle v. Waters, 125 Ind. 265, 267; Durland v. Pitcairn, 51 *157Ind. 426, 444; Cunningham v. Gwinn, 4 Blackf. 341; Sutton v. Bickwith, 68 Mich. 303, 36 N. W. 79, 13 Am. St. 344, and note p. 351.
It is expressly slated in the deed to appellant, that he accepts the same in lieu of, and in full satisfaction of, any claims or interest in the real estate conveyed to his wife, that he has or may have as her heir, or by virtue of the marital relation existing between them; and by his acceptance of said deed and taking possession of said real estate he became and is bound by these conditions in like manner as if he had signed an agreement containing the same. Street v. Chapman, 29 Ind. 142; Smith v. Hollett, 34 Ind. 519; Fairbanks v. Meyers, 98 Ind. 92, 97, 98; Chicago, etc., R.W. Co. v. Derkes, 103 Ind. 520, 523, 524, and cases cited; Thiebaud, Tr., v. Union Furniture Co., 143 Ind. 340, 344.
Construing said deeds together, it is evident that appellant not only released his rights in said forty acres, under section 2642, Burns’ R. S. 1894 (2485, R. S. 1881), but also his rights under section 2651, Burns’ R. S. 1894 (2490, R. S. 1881).
In Glass v. Davis, 118 Ind. 593, cited by appellant, the real estate was conveyed to the wife during coverture as her jointure in the lands of her husband. The court held that the one-third in fee, which the wife takes in the lands of her deceased husband under sections 2640, 2652, Burns’ R. S. 1894 (2483, 2491, R. S. 1881,) was intended to take' the place of the dower to which she was entitled before the passage of the statute, and that the jointure had the same effect on the interest the wife takes under our statute that it had on her dower interest; and that, as jointure merely barred a wife’s right to dower, it only barred her right under the section of the statute giving her said one-third, and not her right as heir under section 2651 (2490), supra. In this case the conveyance was in lieu *158of appellant’s interest in said forty acres as heir of his wife or by virtue of the marital relation between them, and not in lieu of the one-third, as in Glass v. Davis, supra. That case is, therefore, not in point here.
It is next contended by appellant that no title passed by the deed of appellant and wife to the trustee, and that his wife died the owner of the eighty acres of land, for the reason that he could not legally consent to^his wife’s conveyance of her real estate to a trustee upon the express ' condition that one-half thereof should be reconveyed to him, and that she should be barred of all interest therein as wife and heir; that the wife would be the loser in suen a transaction. A married woman may, through the intervention of a trustee, convey her seperate real estate to her husband as a gift, or fora valuable consideration, subject to be avoided for fraud or undue influence on his part. Johnson v. Rockwell, 12 Ind. 76, 79, 80; Hetrick v. Hetrick, 13 Ind. 44, 45; Note to Turner v. Shaw, 9 Am. St. 323, 326; Boyd v. De La Montagnie, 73 N. Y. 498, 502, 29 Am. Rep. 197; Darlington’s Appeal, 86 Pa. St. 512, 519, 520, 27 Am. Rep. 726; Scarborough v. Watkins, 9 Mon. (Ky.) 540, 547, 548, 50 Am. Dec. 528; Jenne v. Marble, 37 Mich. 319, 322; 14 Am. & Eng. Ency. of Law, 559; Reeve’s Dom. Rel., p. 98; Schouler’s Dom. Rel., section 190.
The deed of appellant and wife was executed in all respects as required by the laws of this State, and was sufficient to convey the eighty acres to said trustee. A married woman is authorized to convey her separate real estate by deed in which her husband shall join. Sections 3340, 6961, 6962, Burns’ R. S. 1894 (2921, 5116, 5117, R. S. 1881).
It is settled law that parties in contemplation of marriage can, by contract, settle the rights that each shall have in their own and each other’s property dur*159ing their married life, and that the survivor shall not inherit or take any of the property of the other or any interest therein. McNutt v. McNutt, 116 Ind. 545, and eases cited; Bowen v. Swander, 121 Ind. 164, 168; Wiseman v. Wiseman, 73 Ind. 112; Shaffer v. Matthews, 77 Ind. 83; Richards v. Richards, 17 Ind. 636; Houghton v. Houghton, 14 Ind. 505; Garver v. Miller, 16 Ohio St. 527; 14 Am. and Eng. Ency. of Law, 539; 5 Am. and Eng. Ency of Law, 909.
It follows that, if the deeds in this case had been executed before the marriage of appellant and his wife, that the same would have been binding on both parties. Appellant’s capacity to contract was not impaired by the marriage. He possessed the same power to contract after his marriage as before. He could release his right in the property of his wife during the marriage and his right to inherit from her afterwards, the same after his marriage as before. Wright v. Jones, 105 Ind. 17; Huffman v. Copeland, 139 Ind. 221.
In Wright v. Jones, supra, it was held that when a husband, to secure a life estate in the homestead owned by his wife, verbally promises to relinquish his claim to all other interest in her property, and she, in consideration of that promise, undertakes to vest such life estate in him, the agreement is valid. The court said: “If the husband prefers a life estate in a particular piece of property, and to secure the desired estate promises to accept such a life estate and to relinquish his claim as to all other interest in his wife’s property, and she, in consideration of that promise, undertakes to vest that life estate in him, the agreement is valid, because it possesses all the essential features of a contract. If the contract were carried into effect by the execution of a deed, it would, as it seems to us, be impossible to impeach it. No ground upon which it could be impeached occurs to us, and none has been *160suggested. The difference between the case we have put by way of illustration and the real case consists simply in the method of vesting the life estate in the husband. In the supposed case the method is assumed . to be by deed, while in the real case it is by will. * *
* Once it is granted that, such a contract is valid, then it must follow that the method of vesting the estate is not of controlling importance.” The right of inheritance under the statute may be waived by the husband by an agreement either antenuptial or post-nuptial, or may be restrained by some estoppel which he has imposed upon himself. Roach v. White, 94 Ind. 510; Huffman v. Copeland, supra, pp. 225, 226, 231.
Counsel for appellant, however, insist that a married woman has no power to release her right to inherit the land of her husband, and that, as “appellant’s wife was not barred of heirship in the land conveyed to her husband if she outlived him, he is not barred from inheriting her lands, the agreements being mutual. If such agreement fail as to one of the parties it must fail as to both.” Citing Daubenspeck, Admr., v. Biggs, Admr., 71 Ind. 255, and 1 Wharton on Contracts, section 523. The case cited only holds that the evidence did not establish the antenuptial contract alleged, while the doctrine stated in Wharton only applies to executory contracts, when a promise is the consideration for a promise. In this case the contract is not executory, but was executed, and each party has accepted the deeds. After the deeds were accepted nothing remained to be done by either party. Each party had done all that he agreed to do and all that was intended to be done. Appellant did not make a mere promise to execute in the future a contract releasing his right to inherit said real estate from his wife, but by the execution and acceptance of the deeds he released his right to inherit. When the *161deeds were delivered, this was accomplished, so far as he was concerned. His wife then held the real estate conveyed to her free from his right to inherit the same, or any part thereof. The release by appellant’s wife of her interest, by virtue of the marital relation between them, in the real estate conveyed to him, was not the sole consideration for his release of the real estate conveyed to her. The forty acres conveyed to him formed a greater part, if not all, the consideration for his release. Even if, as contended by appellant, his wife did not have the power to bar her light to inherit the real estate conveyed to him, and she could have inherited the same if she had survived him, his relinquishment of his right as heir to the real estate conveyed to her is not ineffective for that reason, but the same is valid and binding upon him until vacated or set aside. Appellant, having taken possession of the real estate at the time of the conveyance to him, and held possession and received the income and profits thereof for more than ten years, until the death of his wife, is not now in a position to claim that his release, in consideration of which he acquired from his wife title in fee simple to said real estate, is ineffective for any purpose.
In this State, however, there are many contracts between husband and wife which are valid and may be enforced in equity if not at law. Rinn v. Rhodes, 93 Ind. 389; Wilson v. Wilson, 113 Ind. 415; Brown v. Rawlings, 72 Ind. 505; Hollowell v. Simonson, 21 Ind. 398; Goff v. Rogers, 71 Ind. 459; Procter v. Cole, 104 Ind. 373; Rose v. Rose, 93 Ind. 179; Behreley v. Behreley, 93 Ind. 255; Reed v. Beazley, 1 Blackf. 97; Dutton v. Dutton, 30 Ind. 452; Harrell v. Harrell, 117 Ind. 94; Barnett v. Harshbarger, 105 Ind. 410; Wright *162v. Jones, supra; Huffman v. Copeland, supra; Worth v. Patton, 5 Ind. App. 272.
It was a well settled rule before the enactment of statutes enlarging the rights of married women, that contracts between husband and wife concerning the separate estate of the wife were binding in equity. More v. Freeman, Bunb, 205; Livingston v. Livingston, 2 John. Ch. 537, 539. It is said in 2 Story’s Eq. Jurisprudence, section 1372, “Thus, for example, if a wife having a separate estate should bona fide enter into a contract with her husband to make him a certain allowance out of the income of such separate estate for a reasonable consideration, the contract, although void at law, would be obligatory, and would be enforced in equity. * * * So if a husband and wife for a bona fide and reasonable consideration should agree that he should purchase land and build a house thereon for her, and that she should pay him therefor out of the proceeds of her own real estate, if he should perform the contract on his side she also would be compelled to perform it on her side.”
It has been held that a contract between husband and wife, free from fraud or undue influence on his part, whereby she releases her right to inherit the property of the husband if she survives him, is valid. Dakin v. Dakin, 97 Mich. 284, 56 N. W. 562; Chittock v. Chittock, 101 Mich. 367, 59 N. W. 655; 1 Beach on Con., section 475; 2 Beach on Con., section 954. Such contracts on the part of the wife have been recognized as valid, and enforced in deeds and articles of separation. Thomas v. Brown, 10 Ohio St. 247; Garver v. Miller, supra; Farwell v. Johnston, 34 Mich. 342; Randall v. Randall, 37 Mich. 563; Bissell v. Taylor, 41 Mich. 702, 3 N. W. 194; Rhoades v. Davis, 51 Mich. 309, 16 N. W. 659; Robertson v. Robertson, 25 Ia. 350; Owens v. Bank, 31 Md. 325; Glenn v. Clark, 53 Md. 580; Dillinger’s Ap*163peal, 35 Pa. St. 357, 361; Reed v. Beazley, 1 Blackf. 97; Dutton v. Dutton, supra; Hilbish v. Hattle, 145 Ind. 59; Stewart on Marriage and Divorce, section 182-190.
However, as ‘the complaint is sufficient even if appellant’s wife did not have capacity to release her right to inherit the real estate conveyed to him, we need not and do not determine whether or not she has such power in this State. The court did not err in overruling appellant’s demurrer to the amended complaint. For the same reason the court did not err in sustaining the demurrer to the first paragraph of cross-complaint.
The amended second paragraph of cross-complaint alleges a series of transactions between appellant and his wife in her lifetime, upon which appellant claims there is due him a sum of money, and that the same is a lien on the real estate (describing the real estate. in controversy) which she owned at the time of her death. It is also alleged that his wife died intestate, leaving no father or mother or child or children or their descendants surviving her, but left appellant as her only heir at law. It is not alleged that appellees have or claim any adverse interest in said real estate, or in the estate of said deceased. No reason is given for making appellees parties to said paragraph.
It is well settled that a cross-complaint, like an original complaint, must state facts sufficient to entitle the pleader to some affirmative relief, and that it cannot be aided by the allegations of other pleadings in the action. Conger v. Miller, 104 Ind. 592, and cases cited; Masters v. Beckett, 83 Ind. 595; 5 Ency. of Pl. and Prac., 680, 681.
It follows that the court did not err in sustaining appellees’ demurrer to said amended second paragraph of cross-complaint.
There being no available error in the record, the judgment is affirmed.
