On the 8th day of September, 1909, one Chance, as grantor, executed and delivered' to F. A. Heilman and B. E. Heilman, as joint grantees, a deed of conveyance to a certain quarter section of land situated in Sanborn county, this state. F. A. Heilman and B.> E. Heilman were then husband and wife, residing in the state of Illinois. Thereafter, in 1910, F. A. Heil-man, the husband, as plaintiff, 'brought this action against his wife, B. E. Heihnan, as defendant, to‘ exclude her from any right, title, and' interest in said real estate, on the alleged ground that he had paid the entire consideration o’f $6,400 for said land, that the defendant paid no part of said consideration, and that the name of B. E. Heilman had been wrongfully and fraudulently inserted in said deed as a joint grantee. After the service of the complaint F. A. Heilman died, and U. S. Evans, his executor, was substituted as party plaintiff. Defendant made answer, alleging that prior to the purchase of the said South Dakota land she ■had an interest in certain- land owned by her husband in the state of Illinois; that her husband desired to- sell the Illinois land and invest a portion of the proceeds in the 'South Dakota land; that defendant refused to sign the deed to the Illinois land, and that to induce defendant to sign said deed and to surrender and convey her rights and interests in the Illinois land it was agreed ■between her husband and herself that the South Dakota land should be deeded to them jointly; and that in pursuance of such agreement, and not otherwise, she signed the deed ■ to the Illinois land, and the deed to the South Dakota land was made to F, A. Heilman and B. E. Pleiknan as joint grantees, and that by reason thereof defendant is the owner of an undivided one-half interest in said South Dakota land. The trial court made findings and rendered judgment in favor of defendant, from which plaintiff appeals.
[1] It is urged that the evidence is not sufficient to sustain the *502findings. We are of the view that the findings are supported by the evidence. The trial court, among others, made the findings, that defendant refused to sign away her dower interest in the Illinois land unless she received some protection in lieu thereof,, and then it was agreed between defendant and her husband that,, ■if she would sign the .deed to Illinois land, the proceeds of the' sale would be invested in South Dakota land, and the title taken jointly in their names. It is specifically contended that there is. no evidence that defendant had a dower interest in the said Illinois land of her husband. Sections io and u, c. 41, Rev. Stat. of 111. 1911, were offered and received in evidence. We are of the view that these sections show that a surviving wife has a dower interest in the lands of her deceased husband under the laws of the state of Illinois.
.[2] It is also contended by appellant that respondent is-estopped to claim title to the land in question under the said deed from Chance on the ground that a party cannot take any beneficial interest under a will and at the same time set up any right or claim of his own, even if it is otherwise legal and well-founded, which shall defeat or in any way prevent the full effect and. operation of every part of .the will.' It" appears that F. A. Heilman made a will .and codicil whereby defendant was devised the use of certain homestead property in Illinois during her life, or so long as she remained unmarried, and also a money legacy payable annually, so long as- she remained unmarried, which said •devise and legacy were ¡in lieu of dower in her husband’s land. Defendant has not filed any renunciation of the will and codicil of her husband, but is accepting and receiving the property of said decedent under and by virtue of said will and codicil, and has elected to take thereunder. Section 10, c. 41, Rev. Stat. of Ill. 1911, provides that:
“Any devise of land, or estate therein, or any * * * provision made by tire will of a'deceased husband or wife for a surviving wife or husband, shall, unless otherwise expressed in the will, bar the dower of such survivor in the lands of the deceased, unless such survivor shall elect to and does -renounce the benefit of such devise or other provision, in which case he or she shall be entitled to> dower in the -lands and to one-third (1-3) of the personal estate after the payment of all debts.”.
*503Section ii of said chapter 41 also provides that any one entitled to an election under the preceding section shall be deemed to have elected to take such devise or other provision unless within one year he or she shall make written renunciation of such devise or other provision under the will. Appellant therefore contends that, by reason of the premises and the provisions of the Illinois statutes aforesaid, defendant is estopped to claim -title under said deed to the South Dakota land. We are of the opinion that ithis contention is not well founded. The defendant is not claiming title to an undivided one-ha-lf interest in the South Dakota lands under the said will, neither is she claiming it as dower in her -husband’s real estate of which he died possessed; but she claims to own absolute title in' herself of an undivided one-half interest in the South Dakota land, under a deed in force and effect prior to his death and prior to the taking effect of -the will. The will and' codicil do not specifically describe the South Dakota lands, but the -will and codicil -refer to the lands of the decedent as “my real estate,” and the executor is given full power to sell and convey all “my real estate.” This will and codicil do not purport to dispose of or devise the one-half interests in -the South Dakota lands owned by respondent, but by its terms, “my real estate,” only disposes of thé interest therein of decedent at the time of his -death. The claiming and owning by respondent of the title to an undivided one-half interest in and to the South Dakota lands under the -deed from -Chance in no- manner conflicts with any part or provision of said will or codicil. The provisions of sections 10 and 11 of said chapter 41, Rev. Stats, of Illinois, are not applicable to the circumstances of this case.
[3] The defendant called as a witness one Heidt, a son of defendant 'by a former husband. Heidt was permitted to testify, over -the objections of plaintiff, as to the -conversations he had with R. A. Heilman at the time the Illinois land was sold and the deed of conveyance made therefor. The objection and -contention- was made that Heidt was an- incompetent and interested witness under -section 486, Code Civ. Proc. We are -of the view that this contention is not tenable. Heidt is not a party to this action, and can in no manner be bound by any judgment enteren therein. He is n-o-t an -heir of R. A. Heilman, and may never be an heir of defendant, as -defendant has no heirs while she is liv*504ing, and she may outlive -her said son. To make a party an incompetent witness under section 486, such party must have a present, certain, and vested interest in the subject-matter of the suit, and the interest of prospective heirs is too remote to render them incompetent to testify as to transactions with incompetent persons from whom they would naturally inherit. Jones, Ev. §§ 775-791; Ekern v. Erickson, 37 S. D. 300, 157 N. W. 1062. The defendant, B. E. Heilman, was an incompetent witness to testify in relation to transactions with E. A. Heilman in relation to the' subject-matter of this suit, but during her life her son was not; he had no present or vested interest therein.
Finding no error in the record, the judgment and order appealed from are affirmed.
