This suit has for its main object the reformation of a deed executed by complainant and others who are made defendants, to the defendant Joseph Keith. All other relief sought is incidental to and dependent upon such reformation. The controversy is outlined by the following prominent facts: J oseph and Susan Keith, both now deceased, Avere parents of complainant and defendant Joseph Keith and- of William Keith ay ho died leaving as his heirs the other defendants herein. In 1868 lands of the estate of Joseph Keith consisting of a large tract in one body Avere by proceedings in the probate court partitioned between his Avid-oav and the three children to each of AAdiom was assigned a tract described in the commissioners’ report by metes and bounds. The northernmost tract which the commissioners numbered "4” and estimated at 717 acres Avas allotted to defendant Joseph Keith. Adjoining and south of number 4 lay a tract numbered 3, estimated at 410 acres aaíiícIi avrs set apart to Susan Keith, the Avid-oav. This tract numbered 3 lay partly in section 9 and Avas bisected by the section line forming the southern boundary of that section. To complainant Avas assigned *446a tract adjoining her mother’s, and which at one point extended northward so- as to include-ten acres in the southern part of section 9. In 1884 complainant and William Keith received a conveyance from their mother of tract number 3, and William dying his title passed to his four children, one of whom sold her interest to complainant who thereupon claimed an undivided interest of five-eights in that tract. In March, 1892, Susan Keith died, and defendant Joseph Keith thereafter set up a claim to an interest in tract 3, basing- it - upon the cobtention that the conveyance from his mother to complainant and William was procured by undue influence, and he urged also that the tract originally allotted to him was smaller than the commissioners estimated it to be.- Through his attorney, W. P. -Oden, he proposed by letters to- complainant to accept in settlement of his claim a part of tract 3 which in the letter'was designated as follows: “A strip about 150 yards wide down to the section or U: S. land line along and parallel with his the whole length from Mrs. Butts’ to the river. This would be a strip 150 yards wide or about that off the north side of what you and your brother William got a deed to from your mother in 1884, making his corner to the section line instead of to a made line which he claims was- a mistake in the surveyor.” Further negotiations resulted in the signing- and acknowledging by complainant and her co-owners, of a conveyance to defendant Joseph Keith of land, the description of which is to be gathered from the following recital, viz.: “Know all men by these presents that we Sarah E. Woodruff, Lucius J. Keith, Emma O. Keith, Susie J. Ryder and her husband, Jesse W. Ryder, for and in consideration of an exchange of whatever right title and interest we or either of us now own jointly severally either by and under deed executed by Susan Keith, deceased, dated the 28th of June, 1884, or as heirs at law7 or devisees of the estate of Susan Keith, or otherwise, in or to any and all the lands lying and being in sections eight and nine north of the United States land line running east and *447west between said, sections eight and nine and-.sections sixteen and seventeen, the -same being -intended to include all the lands in'said sections eight-and'nine and north of said east and west United States land line that was alloted or set1 apart to said Susan Keith in the partition and division of the estate of’ her husband Joseph Keith, deceased, as shown by the records Of same, and for the purpose of quieting disputes and settling threatened litigation,' we do remise, release; quitclaim, and hereby convey to Joseph Keith all otir right title and interest and"claim in: and to the above described land containing one hundred and five acres, rn-ore or less; situated in township-20, range three east in said State and county, the s'ame being in'exchange for'the right; title and interest the said Joseph Keith may have as an heir at law or devisee in-the-estate of Susan Keith, deceased, or in any other- wise in and to the following described lands: any and al! lands that were allotted to 'said Susan Keith in the partition and division of the estate of -her husband, Joseph Keith, deceased, that lies in sections sixteen and seventeen south of the United' States land line running east and west -between said sections sixteen and seventeen and sections eight and nine as shown by the records of the same containing three hundred and five acres, more or less/-’ etc. Joseph Keith about the same time executed his deed conveying all his interest in such of the Susan Keith lands as lay south of the section line mentioning its quantity as 305 acres, more or less. The deed of complainant and others- to him was left in the hands of Jesse W. Ryder for delivery, and before its delivery Ryder found that the section line was further south than had been supposed and thereupon by agreement with him Joseph Keith executed another deed reciting the mistake and conveying back to complainant 'and her co-grantors a strip two and a half chains wide lying immediately north of the section line. About a year thereafter complainaint discovered that by the deeds as thus made Joseph Keith had obtained considerably more than 105 acres of the Susan Keith tract, and conceiving also that he had in the same way obtained *448title to part of the ten acres in section 9 which she had owned in severalty, she filed this bill to so reform the deed to him as to restrict its operation to 105 acres in a strip along the north side of the Susan Keith tract particularly described by a plat exhibited in the bill.
To warrant a court in decreeing reformation of a conveyance arising from contract, it is not enough that a mistake has been made, or that the minds of the parties never met upon the subject of the conveyance, but it must appear from definite allegations and corresponding proof that there was an agreement between the parties, and the terms of the real agreement must be shown with such certainty as that the proven averments will form a basis for the decree in substantial conformity with the theory of the bill. — Alexander v. Caldwell, 55 Ala. 517; Turner v. Kelly, 70 Ala. 85; Smith v. Allen, 102 Ala. 406; Guilmartin v. Urquhart, 82 Ala. 570; Tyson v. Chestnut, 100 Ala. 571; 18 Ency. Pl. & Pr. 805. In recognition of this principle the amended bill alleges the land intended to be conveyed was a strip containing 105 acres along the north side of the Susan Keith tract and described definitely by the map exhibited. In the evidence it is shown that that strip was located by Milner, a civil engineer, who for that purpose surveyed the dividing line between the tracts of Susan and Joseph Keith according to his understanding of data found in the partitioning commissioners’ report. His survey corresponds to another which he testifies was correct and which Avas made by an engineer who has since died.
This evidence is opposed by the testimony of Civil Engineer EdAvards introduced by defendant Joseph Keith Avho surveyed the partitioning line according to his understanding of data furnished by the commissioners’ report. This survey of EdAvards agrees Avith that of Mil-ner only in running the partition line straight and starting it from the same point at its east end. Its Avestern terminus is considerably south of the Avestern terminus of Milner’s line, thus diminishing tract No. 3, and expanding number 4 as compared AAdth Milner’s survey.
*449To determine from this record whether either or.which of these differing surveys is correct might be difficult if not impossible, but to do so is unnecessary sin.ce testimony of defendant Jos. Keith, which is unimpeached and uncontradicted unless by weak and uncertain inference, and which must, therefore, be believed, is to effect that the Edward’s line has all along been recognized as the southern boundary of his tract and that he has possession of the land lying north of it since 1868. Accepting this as true it is inconceivable that Joseph Keith in seeking to increase his acreage would, have bargained for lands lie liad held so long, whether rightly or not, under the original allotment. Nor is it. probable that complainant or her co-grantors intended to convey such lands; yet the strip to which the bill would restrict their conveyance lies in large part north of the Edwards line and within the tract he had so held.
Wha.t other lands were intended to be included in that conveyance is unimportant, since under the rule referred to the court cannot by way of effecting the intention of parties establish a contract at variance with the one alleged to have been intended.
For like reasons no decree can properly be rendered for the further relinquishment by Joseph Keith of the Susan Keith lands,' for by complainant’s averments of the agreement in connection with the plat exhibited his relinquishment Avould have, to include all those lands excepting the strip located by Milner. According to the' conclusion we have stated, these averments have not been proved and the bill defines no other part of the Susan Keith tract in respect of which relief could be decreed consistently with what is alleged to have been intended by the parties.
We construe the conveyance by complainant and others to Joseph Keith as limited to lands in the Susan Keith tract and not as including in its description of lands conveyed any part of the ten acres in section 9 owned by complainant in severalty. Hence no relief is needed in respect of that ten acre tract.
*450The decree appealed from wall be reversed, and one wall be liere renrered dismissing the bill.
Reversed and rendered.
