This is a bill in equity for the specific performance of a contract made by a husband and wife to convey her separate property.
The alleged agreement is contained in a receipt given for part payment of the purchase money. This is no objection to its validity. The form of the memorandum is immaterial, if its contents adequately set forth the agreement. Barry v. Combe, 1 Pet. 640. Evans v. Prothero, 2 Macn. & Gord. 322. In this case the paper was signed by both of the parties sought to be charged, and the only objection made to it is, that the premises to be conveyed are not "sufficiently described. It is conceded to be in legal effect a contract to convey “ a house and lot of land situated on Amity Street, Lynn, Mass.” And the question is, whether such a description is void for uncertainty.
The strength of the argument against its validity is, that no particular house and lot are thereby identified; that the terms would be satisfied by the conveyance of any house and lot on that street; and that parties may enter into'a binding agreement to convey real estate which they do not own.
But this view leaves out of sight some important considerations. Mrs. Brown, being a married woman, was incapable of binding herself personally by a common contract. Her promise eould have no validity except so far as it related to her separate *547property actually owned by her at the time. This circumstance is of weight in determining whether this agreement referred in definitely to any estate on Amity Street, or definitely to some one which the wife might make a valid contract to convey. It is true that an agreement may be made to sell an estate which the vendor does not own, and he may be liable in damages at law for failing to perform it. But specific performance in equity would not be decreed in favor of a vendor who at the time of the bargain was not the owner of the estate which was the subject thereof, or had not the power to become the owner by legal or equitable proceedings. Tendring v. London, 3 Eq. Cas. Ab. 680. Mortlock v. Butter, 10 Ves. 315. Pipkin v. James, 1 Humph. 325.
We think that the presumption is strong that a description which actually corresponds with an estate owned by the contracting party is intended to apply to that particular estate, although couched in such general terms as to agree equally well with another estate which he does not own. This would be apparent if the memorandum related to personal property. For example, if a man made a written bargain to sell “ a horse,” and he then owned one horse only, we suppose that no one would doubt that the contract was to be construed to relate to that particular animal. This court has decreed specific performance of an agreement to convey “fifty shares of Providence & Worcester Railroad stock,” a description which does not identify any specific shares. Todd v. Taft, 7 Allen, 371. No more particular description is necessary under the statute of frauds, in a contract for the sale of real estate, than in one relating to personal property. In each, to constitute a bargain and sale, or a contract which will be specifically enforced in equity, the subject matter thereof must be identified.
In a deed, the words of description are, of course, intended to relate to an estate owned by the grantor. And, in our opinion, this is also the presumption in construing a contract for a future conveyance. If the party who enters into the agreement in fact owns a parcel answering to the description, and only one such, that must be regarded as the one to which th» description refera *548With the aid of this presumption, the words “ a house and lot ” on a street where the party who uses the language owns only one estate, are as definite and precise as the words “ my bouse and lot” would be; a description the sufficiency of which has been placed beyond all doubt by very numerous authorities. Bird v. Richardson, 8 Pick. 252. Phelps v. Sheldon, 13 Pick. 50. Atwood v. Cobb, 16 Pick. 227. In both cases the same extriiuic evidence must be resorted to, by the aid of which all uncertainty is removed. Where the words used are “ my estate ” in a particular locality, oral evidence is necessary to show what estate the vendor did own. A latent ambiguity always exists where the party owns two parcels, to each of which the description used is equally applicable.
In the present case the writing does not show that there is more than one house and lot on Amity Street. This fact was disclosed by the oral evidence at the trial; and the familiar rule would seem to apply, that parol evidence is admissible to explain and remove a latent ambiguity. If there had been only one house and lot on the street, there would have been no indefiniteness in the description. The supposed uncertainty having been created by parol, evidence of the same character may be resorted to for its removal. But, without relying much upon this consideration, we regard the fair construction of the words used to be, that they relate to a house and lot owned, at the time the memorandum was signed, by the parties who subscribed it. Thus interpreted, they are sufficiently certain, and the oral evidence is needed only to apply the description. This must be done by extrinsic evidence in every contract or conveyance, however minutely the boundaries of the estate may be set forth. The maxim, id certum est quod certum reddi potest, is the established rule of construction in suits for specific performance. The contract in the present cáse seems to us fairly within its application.
Farwell v. Mather, 10 Allen, 324, upon which the learned counsel for the defendant relies, was an action at law for damages, in which the insuperable difficulty was, that, by the terms of the memorandum, the nature of the estate was left uncertain. *549It was in fact a leasehold interest, but the words of the written contract were ambiguous, and might as well describe an estate in fee. An agreement to sell a house imports an agreement to convey the title thereof in fee. Hughes v. Parker, 8 M. & W. 244. The nature of the title to be conveyed in the present case is therefore free from doubt, and the description of the property is the only matter in controversy.
Murdock v. Anderson, 4 Jones Eq. 77, is certainly not easy to reconcile with the conclusion we adopt. But its authority is, in our opinion, outweighed by the considerations already stated, in further illustration of which one or two additional cases may be referred to. “ Philo Baldwin’s right in Donald Baldwin’s estate ” has been held a sufficient description to satisfy the statute of frauds. Nichols v. Johnson, 10 Conn. 192. “ Mr. Ogil vie’s house ” was deemed definite. enough, in a suit for specific performance. Ogilvie v. Foljambe, 3 Meriv. 53. And the following words in a letter were held to warrant a decree against the writer: “ I have sold the house, &c., in Newport,” (then follow the price and terms of payment,) “ the money to be paid as soon as the deeds can be had from Mr. Dease.” Owen v. Thomas, 3 Myl. & K. 353. See Fry on Specific Performance, §§ 209, 212.
Our conclusion is, that the plaintiffs are entitled to a decree for specific performance. Unless the parlies agree as to the terms of the deed and as to the payment of the purchase money, the case must be referred to a master to report the form of the conveyance and to ascertain the sum due on account of the purchase money. If any claim is made that interest should be charged upon the portion unpaid, he will also report all the facts relative thereto.
