On the third day of June, 1872, Houston McFarland and Sue B. McFarland were husband and wife, living together as such at Weston, Platte county, Missouri. On that day she borrowed from one John E. McFarland the sum of $450, for which she executed her personal note payable in three{ years from its date with interest at ten per cent per annum. On the twenty-fifth day of June, 1872, Sue B. McFarland purchased from George G. Pounds the land in controversy and received a deed therefor conveying to her the fee simple title thereto. On June 28, 1872, she mortgaged said property, her husband joining with her, to John E. McFarland to secure the payment of said note. By the mortgage, power of sale was vested in the mortgagee, John E. McFarland.
There is recited on the face of the mortgage with respect to the land the following, to wit: “The same being the sole and separate estate of the said Sue B. McFarland.” And in the certificate of acknowledgment the following, to wit: “And the said Sue B. McFarland, being by me first made acquainted with the contents of said instrument, upon an examination separate and apart from her said husband, acknowledged that she executed the same freely and without fear, *72compulsion, or undue influence of her said husband, and desires to convey her separate estate therein.”
There were born to Houston McFarland and wife two children only, Mary and Maggie, who were. fourteen and sixteen years of age, respectively, in 1872. On March 8, 1877, Sue B. McFarland died, leaving her husband tenant by the curtesy and said daughters surviving her, her only heirs at law.
On June 13, 1878, John E. McFarland, the mortgagee in said mortgage deed, sold said property under the power of sale therein contained authorizing him to sell, at which sale Houston McFarland became the purchaser at the price of $300, and on said day he received a deed for said land from said mortgagee. On September 6, 1879, Houston McFarland conveyed said land to Charles A. Hazen, who, on February 15, 1887, conveyed the land to the defendant, M. W. Hutchinson. «Houston McFarland died June 8, 1888.
Maggie McFarland married Arthur Q-. Meads and died prior to the institution of this suit without having issue born alive, leaving her sister, Mary F. Coekrill, who intermarried with C. B. Coekrill, her only heir at law.
When Hutchinson bought the property he had no knowledge of any claim by plaintiffs thereto. It was then practically vacant, no improvements being on it except a house of but little value. Since then he has put lasting and valuable improvements thereon, of the aggregate value of about $10,000.
On the thirty-first day of December, 1892, plaintiffs instituted this suit to redeem from the sale under said mortgage, on the ground that the title acquired by Houston McFarland by virtue of his purchase and deed under said mortgage sale was for the benefit of himself and his two daughters then living, he being tenant for life in possession, and his daughters remainder-men.
*73The court below dismissed the bill, and rendered final judgment against plaintiffs in favor of defendants for costs. Prom the judgment plaintiffs appealed.
There is nothing in the deed from Rounds to Mrs. McFarland, which can be construed as creating in her a separate estáte to the land in question; nor is any such contention made by defendants. Nor could she by any act of her own, or by any statement made in the mortgage, create a separate estate in the land in herself. The same is true with respect of the recital in the certificate of acknowledgment to the mortgage in which it is stated, “and she desires to" convey her separate estate therein,” that is, in the mortgage. Such recitals were inoperative to create a separate estate in her.
At the time she executed the note to John E. McFarland she did not own the land, nor does it appear that she owned any separate property; but notwithstanding such was the case, the subsequent acquirement by her by purchase of the land, the mortgage executed by her and her husband Houston McFarland thereon, to secure the payment of her debt, was a valid and binding mortgage. It has been repeatedly held by this court, that a mortgage executed by a married woman, her husband joining with her, although on land not her separate estate, is valid and binding, notwithstanding the note, the payment of which is secured by the mortgage, is void because of her coverture. Comings v. Leedy, 114 Mo. 454; Hagerman v. Sutton, 91 Mo. 519; Wilcox v. Todd, 64 Mo. 388; Meads v. Hutchinson, 111 Mo. 620.
The effect of the sale under the mortgage, the purchase by Houston McFarland of the land at the sale, and the execution of the deed to him by the mortgagee was to pass the legal title of the land to said McFarland, and the purchase by him must be deemed to have been *74made for the benefit of himself, and the remainder-men, if the latter had seen fit to pay their share of the purchase money within a reasonable length of time thereafter.
Thus in 1 Washburn, Real Property [5 Ed.], 129, it is said: “If a tenant for life purchase in an outstanding incumbrance upon an estate, it is regarded as having been done for the benefit of the reversioner as well as himself, if the latter will contribute his proportion of the sum paid therefor.” Allen v. DeGroodt, 105 Mo. 442; Meads v. Hutchinson, supra; Hinters v. Hinters, 114 Mo. 26; Dillinger v. Kelley, 84 Mo. 561.
It follows from what has been said that the plaintiff Mrs. Cockrill has the right to redeem from the mortgagee’s sale, unless she is estopped from so doing by reason of the recitals in the mortgage, and the'certificate of acknowledgment heretofore quoted, or she has forfeited her right to redeem by reason of her own laches, or that she should not be permitted to do so against defendants who claim to be innocent purchasers in good faith without any notice of her equity, if any she had. Of these in their order.
While it is conceded by defendants that as a general rule a married woman is not estopped by matters in pais, it is contended that this does not license her to commit a fraud to the injury of others, and that her acts and representations which do deceive others to their injury will preclude her from asserting her claim against those who have acted on her representations and admissions.
We have already said that Mrs. McFarland did not own a separate estate in the land in question. Therefore she was not estopped, nor is plaintiff who claims under her estopped, by the recitals in the mortgage from claiming the land. It has been held that recitals in a deed made by a married woman do not estop her or *75those claiming under her. Crenshaw v. Creek, 52 Mo. 98; Hempstead v. Easton, 33 Mo. 142. Moreover, estoppel is not pleaded in the answer, which is absolutely necessary when relied upon in pais as a defense. Throckmorton v. Pence, 121 Mo. 50, and authorities cited.
The legal title to the land passed to Houston McFarland by the mortgagee’s deed of June 13, 1878 (Meads v. Hutchinson, supra), at which time the cause of action of plaintiff and her sister Maggie accrued. One of them was then about twenty, and the other about twenty-two years of age, both of legal capacity to sue (section 1, page 466, Genl. Statutes, 1865), yet this suit was not instituted for about fourteen years thereafter, to wit, December 31, 1892. Since Hutchinson’s purchase of the property he has greatly improved it and its value has largely increased. Would it be equitable to allow plaintiff who has for so long a time slept upon her rights to now come in and redeem the property by paying a part, or even all, of the purchase money, with interest, paid for it by her father at the mortgagee’s sale, and wrest it from defendants who purchased it, and have improved it, in good faith.
It is true that from August 1, 1881, to October, 1892, there was an action pending for the possession of the land in which plaintiff and her sister Maggie were plaintiffs, against these same defendants, but even that does not impress us with the justness of plaintiff’s claim or relieve it of the unfavorable impression that its staleness is calculated to create upon a court of equity.
In Mandeville v. Solomon, 39 Cal. 125, it is said: “Equity does not deny to a tenant in common the right to purchase in an outstanding or adverse, claim to the common property; it, however, deals with the tenants after such a purchase is made. While it will not permit one of them to acquire such a title solely for his *76own benefit, or to the absolute exclusion of the other, it at the same time exacts of that other the exercise of reasonable diligence in making his election to participate in the benefit of the new acquisition; and having, upon its own principles of fair dealing, compelled the purchasing tenant to allow his cotenant this opportunity, the latter will not be permitted to equivocate or trifle with the position thus afforded him, or to make it a means of speculation for himself, by delaying, until the rise of the land, or some event yet in the future, shall determine his course. Unless he make his election to participate within a reasonable time, and contribute or offer to contribute his ratio of the consideration actually paid, he will be deemed to have repudiated the transaction and abandoned its benefits.” See note to Keech v. Sandford, 1 Wh. & T. Lead. Cas. in Eq., p. 70; Lee v. Fox, 6 Dana, 176; Weaver v. Wible, 25 Pa. St. 270; Lloyd v. Lynch, 28 Pa. St. 419.
The application of this just rule must be invoked in this case, and when this shall'have been done is decisive thereof. After plaintiff has for so long slept upon her rights, without any manifestation of a desire to share the burdens of the purchase by her father at the mortgagee’s sale, and thereby avail herself of its possible benefits, until the property has been improved and greatly enhanced in value, it would be inequitable to now permit her to do so. We therefore affirm the judgment.
