The note being in form a joint contract of husband and wife was, within the meaning of the statute, executed -with his written consent. Farthing v. Shields, 106 N. C., 289; Flaum v. Wallace, 103 N. C., 296. While she did not specifically charge her separate personal estate or enter into a contract in any way enforcible against her by merely signing such a note as is described in the record sent up, she did afterwards bind the land conveyed in the mortgage deed executed by her husband and herself. Farthing v. Shields, supra, at p. 299; Thurber v. LaRoque, 105 N. C., 301; Williams v. Walker, 111 N. C., 604. She might have so encumbered her own land to secure a debt of the husband created for and enuring solely to his benefit. Shinn v. Smith, 79 N. C., 310; Newhart v. Peters, 80 N. C., 166.
*201Here however it is found as a fact that the money which was the consideration of the note, was paid to her and was expended by her in building a house, which of course enhanced the value of the land sold. It was competent and pertinent as between*the parties- interested to enquire into the consideration. Flaum v. Wallace, supra; Jeffries v. Green, 79 N. C., 330.
The wife died, leaving as her only heir-at-law the infant petitioner, R. M. Freeman, Jr., who, with his next friend appointed by the Court, joins his father, R. M. Freeman, tenant by the curtesy, in the petition to sell the land. The sole question presented by the appeal is whether the mortgage debt, which is a lien upon the land, is to be first discharged out of the purchase money arising from the sale of the land, and then the present value of the husband’s life estate in the residue ascertained and paid to him, or whether the present value of his life estate in the whole fund is to be first determined and the whole, or so much of it as may be necessary, applied to the payment of the debt in exoneration of the interest of the heir-at-law. The wife was not surety for the husband and her infant heir-at-law cannot invoke the aid of the principle approved in Weil v. Thomas, 114 N. C., 197, for the reason that his mother did not mortgage her land to secure a debt created by the husband for his own benefit, but to procure money to be expended on the improvement of her separate real estate. The right of the wife to secure the payment of money expended in the improvement of her own land by conveying it by a mortgage deed, in which the husband joins and with privy examination of herself, cannot be questioned, as was said by the present Chief Justice in Jeffries v. Green, supra, “except upon the theory that a feme covert cannot sell or charge her separate estate for her own benefit or the improvement of her own property.”
*202The consideration of the debt having enured to the enhancement in value of the very tract of land now sold, it would be inequitable, when the purchase money comes into Court for division between her husband, as tenant by the curtesy, and her heirs-at-law, to devote so much of it as is due him in lieu of his life estate to the payment of the unpaid balances on the note, on the ground that she, as surety, had pledged her property for his debt. Atkinson v. Richardson, 74 N. C., 455. Such a ruling would be founded upon a theory clearly contradictory of the facts explicitly found by the Court as the basis of the decree.
