Opinion op the Court by
Judge CarrollReversing.
Appellants are the owners of a lot, with a store building thereon, in the city -of Lebanon. Appellee owns the adjoining lot. Both lots were formerly owned by one Ben Spalding, and the parties to this litigation acquired their respective lots by various conveyances. For a eonsderable time, the buildings oh both lots extended back the same distance from Main street; the dividing wall between them being recognized as a joint or partnership wall. After-wards, appellants’ vendors increased the depth of their store building by extending the division wall on the line between the lots, and erected a wall two stories in height above the ground. The extension of the partnership wall between the two buildings was *513made by tbe appellants’ vendors at their own expense, with the expectation, belief, and assurance that, when appellee or his vendors should extend their building and use the wall erected by appellants’ vendors for the purpose of building on or to it, they would contribute their share of the expense of erecting, it, or pay to appellants one-half of the value of the wall so taken • and used at the time it should be used. Appellee acquired title to his lot in 1881, and since then at various times he has extended the store building on his lot, until the storeroom now, reaches to the end of the wall erected by appellants’ vendors, and is using and utilizing the wall as the eastern wall of his building. Appellee refusing to contribute anything to the expense of erecting the wall made by appellants’ vendors, or pay any part of the value of the wall used by him, they brought this action, seeking to recover from appellee one-half the value of the wall erected by their vendors and used by him. To their petition a demurrer was sustained, and judgment entered dismissing it.
The statement of the facts heretofore made is taken from the petition, and for the purposes of this appeal must be accepted as true. There was no written or other agreement between any of the parties concerning the erection or use of this partition wall, so that the question to be decided may be thus stated: Will a person, who uses for his own convenience and benefit an adjoining wall erected by another person, be required to contribute to the vendee of the person erecting the wall one-half, or his fair proportion of the cost thereof? The center of the wall erected by appellants’ vendors was the dividing line between their lot and the adjoining lot, now owned by appellee, and it may be conceded that, at *514any time before appellee took possession of the wall or commenced to use it as a party or partnership wall, it might have been removed by 'the persons who erected it or their vendees. Appellants, under the conveyances, became entitled to all the rights in the wall that their vendors had; in other words, their status was the same as if the wall had been erected by them. So that the question, when narrowed down, resolves itself into this: If A. erects a wall, the center line of which is the dividing line between his property and that of B.’s, and afterwards B. uses the wall without any agreement or arrangement, written or otherwise, to contribute to the expense of erecting the wall, will the mere fact that B. is using it as one of the walls of the building erected by him entitle A. to recover from B. his proportionate cost of the wall?
When appellee built up to this wall, and used it as one of the exterior walls of his building, appropriating to himself the use of the wall, and enjoying the benefits of the labor and money expended by the persons who. erected it, it would seem fair and just thát he should be required to contribute toward the cost thereof. Numerous questions concerning party walls ‘have come before the courts, and in many material particulars there is wide conflict and difference in the opinions concerning the rights and liabilities of the persons-who erected the walls and those who use them. Generally, party walls are erected under an agreement as to their use, and in many states are regulated by statute, and often an issue has arisen as to whether these agreements are personal to the parties or covenants-running with ‘the land and enforeible by and against remote vendees '•'of the'persons who made the agreement at the time *515the wall was built. There was po privity of contract respecting this wall between appellants and appellee; nor can it fairly be said that appellee had any connection with the “expectation, assurance, and belief” existing in the mind of appellants’ remote vendor when he erected this wall. But, back of this, there stands out in support of appellants’ claim the substantial fact that appellee has appropriated to his own use a part of this party wall erected by appellants’ vendors, without having paid anything therefor. So that, aside from any of the distinctions that involve the law of party walls in obscurity and doubt, there remains the proposition strongly put in behalf of appellants that justice and fair dealing demand that appellee should contribute towards the payment of a wall that he has used to his advantage and benefit. Indeed, it might with propriety be said that the question here involved partakes more of the nature of a suit for contribution than one involving the doctrine of party walls. Placing the case upon ■this ground simplifies very much the question to be disposed of. -We need not inquire into the law concerning covenants running with the land, as it bears upon the question of party walls ; nor is it necessary to attempt to reconcile the conflicting decisions touching the rights of remote vendees in respect to them. There is authority founded in reason and justice that requires a person who uses a party wall, in the .absence of any agreement or contract, -to contribute ,hds fair proportion of the cost.thereof to .the.person erecting the wall, or,,to put it in another and perhaps a better way, to pay a reasonable price for .the use of the wall.
One of the earliest cases in support of this doctrine is Campbell v. Meiser, 4 Johns, Ch. 335, 8 Am. Dec. *516570, where Chancellor Kent, writing held that where one owner rebuilt a party wall that was used by the adjacent owner, the latter might be required to contribute to the expense of its erection, saying. “I have not found any adjudged case in point, but it appears to me that this 'case falls within the reasonable and equitable doctrine of contribution, which exists in the common law, and is bottomed and fixed on general principles of justice.” Looking in the same direction is Day v. Caton, 119 Mass. 513, 29 Am. Rep. 347, where the court held that, although a promise to pay for a party wall would not be implied from the fact that the builder, with the knowledge of the adjacent owner, erected the wall, yet such promise might be inferred from the fact that the person erecting the wall undertook and completed it with the expectation that the adjacent owner would pay for it. In Sanders v. Martin, 2 Lea (Tenn.) 213, 31 Am. Rep. 598, the facts were very similar to those here presented. Sanders and Martin owned adjoining lots in the city of Memphis, separated by a party wall. The houses were two stories high without any cellar. Sanders erected a three-story brick house on his lot, and used the party wall, raising it one story higher. He also, with the consent of Martin, made a cellar, which necessitated underpinning the party wall by a wall of the same thickness, one half on his lot and the other half on the lot of Martin. Sanders expected thát, when Martin came to use the cellar and raise his house higher, he would contribute one-half the actual cost of these improvements. After-wards Martin erected a building on his lot, using in its construction the wall erected by Sanders. Thereupon Sanders brought an action for contribution against Martin. In the opinion, the court said: *517“The common law is singularly obscure on this subject, and the decisions few, conflicting, and unsatisfactory. It seems certain that the common law does not recognize the right of the owner of land to compel the owner of an adjoining lot to build a party wall; nor can either demand contribution from the other for a wall erected in whole or in part on the land of such other person, nor for any incidental benefit the latter may derive from a wall erected entirely on the land of the builder. The authorities stop short of the case before us, and that is, whether, after the wall has been underpinned and raised in height by one for his own convenience, he can claim contribution from the co-owner when the latter' actually uses these additions. In the forum of conscience the answer would at once be that the latter ought to pay the former for the benefit received by his- labor and expenditure. The argument of the learned counsel for the defendants is that this court is governed by the law, not by principles of' abstract right; that the defendant Martin is not entitled' to treat any erection made by a third party on his own land as his own; and, in fine, that the client stands upon the letter of the law, and claims all he can get. If one owner can rebuild a party wall, which has become dangerous, and compel contribution, it is clearly upon the equitable and moral principle that the expenditure is for the benefit of both, and that the right of easement is a sufficient basis upon which to justify interference and raise an implied contract. The same basis exists where a wall is added to and actually used. If both of these parties had dug their cellars and added additional stories to their houses at the same time, although only one of them built the addition to the party wall, a promise by the other to pay for the moiety of the *518wall would bé implied. Is there any reason in law why the same implied promise would not arise where, after the addition had been made by one, the wall was used by the other? The relation of the parties created by the joint easement in the new wall would seem to be as efficient in the case of an addition to the wall as in the case of rebuilding the same wall. Upon the case made in the bill, if established by the testimony, the complainant is entitled to relief. The measure of relief, however, is not the cost of the additions to the wall, but the moiety of the value of the additions at the time they were actually used by the defendants. They might never have been used, in which ease no contribution whatever could be had. They might have been erectéd when the work for some reason exceptionally costly, and used wheh the wall could have been done at half price, or when the wall itself had become clilipidated by time. Martin, cannot be called upon to pay more than half the value of the wall when used. ’ ’ In Willford v. Gerhard, 22 Ky. Law Rep. 203, 56 S. W. 416, the coiirt quoted with approval Campbell v. Mesier, and Sanders v. Martin, and upheld the doctrine of contribution in cases of party walls.
The conclusion we have reached is not free from doubt, and is contrary to the views held by a réspeetable number of courts; but we are of the opinion that a person who uses a wall erected on the dividing line by the ownér of the adjacent lot should pay a reasonable and fair price for the use thereof, estimated as of the time when the user'takes place. And this, although neither he nor his véndor was a party to the erection of the wall, and made no agreement, express or implied, concerning it.
*519The judgment is reversed, with directions to proceed in conformity with this opinion.
