¶1John Stennett died intestate, March 30, 1913, seized of the NW y4 NE % of Section 34, the N i/2 SE % of Section 26, and the SW % NE % of Section 26, in Township ■ 86 N., of R. 34 W. of 5th P. M. His wife had departed this life some time before, and he left surviving the following children only: William J., Frank, Ruben J., and Charles M. Stennett. On December 11, 1911, the deceased entered into a contract with Ruben and Charles, wherein it was stipulated that:
*433“In consideration of the party of the first part (John Stennett) executing a warranty deed to the parties of the second part (Ruben and Charles), to the Southwest Quarter and the Southwest Quarter of the Northeast Quarter and the East Half of the Southeast Quarter of the Northwest Quarter of Section Thirty-four, Township Eighty-six North, Range Thirty-four West of the 5th P. M., Iowa, and the further consideration of the releasing of the parties of the second part from all claims now held against said parties of the second part by the party of the first part, the parties of the second part hereby agree upon their part to pay off and discharge the $2,500.00 mortgage to Mary E. Stevens, together with the interest from December 1st, 1911, and agree to pay the drainage taxes and assessments now levied or to be levied on said described land, and they further acknowledge said conveyance and settlement as a full advancement of each and all their interests in and to the estate of John Stennett, and hereby agree to release and relinquish at any time when called upon to do so by quitclaim deed or otherwise any and all interests which they may have in the estate of John Stennett at his death, hereby agreeing to quitclaim and relinquish to the legal heirs or devisees of John Stennett as the ease may be any and all interests in and to his real estate and personal property of which he may die seized or possessed, the intention being that the above conveyance shall be an advancement and full settlement of all the interests said parties of the second part may have in the estate of John Stennett at his death.”
¶2The sons also agreed to pay the expenses of such settlement by way of fees of $50 each to the respective attorneys. All three signed this agreement, and on the same day, John Stennett executed to Ruben and Charles a warranty deed conveying to them said land subject to the mortgage thereon, and reciting that “this deed is made as the advancement of the shares or interest the said grantees have or may have in the estate of the grantor”. On September 8, 1913, William *434and Frank caused to be served on Ruben and also on Charles a notice addressed to each separately and signed by both William and Frank, “requesting each to execute to them a quitclaim deed of real estate of which John Stennett died seized within 20 days thereof”, tendered to each $1.25 for the expense of so doing, and advised each that, upon failure to comply, action to quiet title would be brought, under Section 4226 of the Code. Thereupon, separate suits were begun against each of defendants, praying that title to said lands be quieted in William and Frank, and that the contract be specifically performed. These suits were consolidated, when Frank filed a petition of intervention, alleging that he was made plaintiff in said suits without his consent and would not prosecute as such, and further, that, about March 1, 1912, he entered into oral agreement with his father, John Stennett, by the terms of which he was to use and occupy the N y2 SE yl and the SW *4 NE y^ of said Section 26, known as the home place, during the life of said John Stennett, was to care for him and pay him $3.00 an acre, if his father should require same, and by which, if said intervener performed his part of said oral contract, the said real estate would be and become the property of this intervener upon the death of said John Stennett; and that he (the intervener) had fully performed his part of the contract, and prayed that title to said land be quieted in him against the other parties to the action. The answer of William put these allegations in issue and averred that Frank is estopped from claiming the entire 120 acres of land. Later, William amended the petition by alleging himself the owner of an undivided half interest in the- 160 acres, and prayed relief accordingly. The defendants, Ruben and Charles, alleged, among other things, that the deceased, prior to his death, revoked the contract with Ruben and Charles, and that it is void as against public policy, and was never delivered.

¶4The evidence of witnesses indicative of an unexecuted purpose o'f deceased to make a future disposition of the property “lends little countenance to the idea that he had already made such a definite and specific contract to convey as to prevent his changing his mind and refusing to carry out the arrangement if he saw fit”. Boeck v. Milke, supra; McDonald v. Basom, 102 Iowa 419.
¶5The tendency of most of the evidence was to prove a purpose on the part of deceased that Frank should have the 120 acres. Such evidence, though proving a favorable disposition and an existing design to bestow the property on the claimant in the future, is entirely consistent with the nonexistence of any contract, and therefore not of much probative force. The testimony of but two witnesses bore directly thereon. One Srfford swore that he had lived on the farm before Frank returned; that he had a conversation with John Stennett, in the course of which he advised him (Stennett) “to get Frank and his wife back”; that deceased said to the witness, “The next time you see him, you have a talk with him and find out if he would come back”; that when he met Frank the next *436time, he told him what had occurred, and Frank responded that he had a better thing, and on being asked “What would you do?” said that “if he could get off up there, he would go down there and pay the old man $3.00 an acre for the land and keep him and his team as long as he lived, if he would get that place when the old man was through with it”. The witness testified further that he told John Stennett what Frank had said, to which the former responded that “if he would do that, he ought to have the place”, and said, “You tell Frank that”, and the witness informed Frank. It will be noticed that what the deceased said was that he ought to have the land if he would do that; but there was no agreement shown, even through this witness.
¶6The plaintiff’s ease, then, necessarily rests upon the testimony of one Ben Spore, who appears to have lived with deceased during the winter of 1911 and 1912, and testified to having been there when Frank talked with his father about moving back, and that “The old man told him that if he would come down there and take care of him the rest of his life, he would give him the 120 acres when he was through with it, the home place. He was to have $3.00 per acre provided that he called for it and Frank was not to pay for it until he asked for it. Frank told him he would come down under this condition.”
¶7Frank moved on the farm about the 2d of March, and the witness left the next day. He (the witness) testified further that the deceased used the term “the home place”, which was the 120 acres in controversy. On cross-examination, it appeared that this witness had been stopping with Ruben and Charles; that during the previous year and a half, he had been in six different states, drifting from place to place; and that, ever since he “grew up”, he had “wandered from one place to another”, except when he made his headquarters with Ruben and Charles. His credibility was further somewhat impaired by the testimony of William’s wife, that Spore *437had said to her at the time and place mentioned in questions to Spore, in response to an inquiry of him whether he had heard Frank ask or demand a deed to the home place of his father, that Grandpa answered, “Not by a damn sight; that any fool or stranger would come into the home place if he could get a deed to it; . . . that if Frank came back, he would have to come back as a renter.” Moreover, there is much in the record indicating the claim of Frank to have been an afterthought. Thus, he signed the notices demanding quitclaim deeds from Ruben and Charles to him and William, and made no objection to the statement of the attorney indicating that if quitclaim deeds could not be procured through another attorney, he would begin suit. He gave the attorney the description of the real estate, and, upon saying he could not qualify as surety on the bond of William as administrator of the 'estate of deceased, was informed by the attorney that he was owner of an undivided one half of the 160 acres left by his father, and immediately signed and qualified. Again, he agreed to continue in possession at a rental of $3.00 an acre and admitted owing a balance of $240 as rent for the year previous to his father’s death. ■ According to William, he expressed his dissatisfaction because the farm was not left to him, but did not mention any agreement with his father until in November, 1913, when he refused payment of rent. Frank insisted that he told William of the alleged agreement in the spring and testified to having agreed with Ruben and Charles that if their contract with deceased were broken, he would convey to them his interest in the 40 acres, and that they would quitclaim to him their interest in the 120 acres constituting the home place. Enough has been set out, without alluding to other items of evidence, to have justified the trial court in rejecting the intervener’s claim. If Mrs. Stennett is to be believed, Spore was impeached; for he was unable to recall whether he made the statement to her. Moreover, his mode of lifé was such as to throw doubt upon his *438credibility. Add to this the equivocal attitude of the intervener, and it may safely be said that the proof falls far short of being of the character exacted by the rules of evidence in such cases, and there was no error in dismissing the petition of intervention.

¶10*439It appeared that a twin brother of William’s died about ten years previous to the trial, and that a sister, Mary, departed this life in 1881, after having married. Though the law presumes, in the absence of evidence to the contrary, that an intestate has left heirs capable of succeeding to his estate, there is no presumption as to who they “are, and as all are single when young, this status will not be presumed to have been changed. But the sister had been married, and from this fact, the law raises the presumption that she left issue surviving. Skinner v. Fulton, supra; Faulkner v. Williman, (Ky.) 16 S. W. 352; Stinchfield v. Emerson, 52 Me. 465 (83 Am. Dec. 524); Posey v. Hanson, 10 App. D. C. 496. Whether this is a presumption of law or an inference to be drawn from the fact of marriage is not material to determine; for in either event, the record contains nothing tending to overcome it. The four sons were not shown to have been the only heirs.
