The bill in this case was filed to correct a mistake in a party-wall agreement, and to restrain the further prosecution of an ejectment suit brought against the grantee of complainants. The testimony on the hearing disclosed the following facts: Prior and up to the fall of 1893 the complainants (who are husband and wife) and the defendant owned adjoining parcels of land on the south side of East Main street in the city of Jackson. The complainants’ premises lay just east of the defendant’s. By the descriptions in their respective deeds the complainants’ lot had a frontage on Main street of 18 feet, and the defendant’s of 15 feet. The front portions of both parcels were covered by old wooden buildings, which directly adjoined each other, and had been occupied for business purposes for more than 20 years. During all of that period, each party and their grantors had possessed and occupied these buildings as their property without question or dispute as to the division line, and as though the line between these buildings was the true division line between their respective premises. In the fall of 1893 the complainants determined to join with one Neesley, who owned the lot next east of theirs, in building a modern brick building covering substantially both of their lots, and having a united frontage on Main street of about 46 feet. They tore down the old wooden buildings on the premises, and began excavating for the foundation walls.
The defendant resided at Rouse’s Point, N. Y., and left his property in general charge of his nephew, Frank Heaton, who resided in Jackson, and was defendant’s agent for the purpose of collecting the rents, making repairs, and overseeing this with defendant’s other real *207estate in Jackson. When the complainants began to make excavations and lay in said concrete and foundation, said Frank Heaton, who was about the premises overlooking the matter for the defendant, thought that complainants were crowding the foundation and wall over on defendant’s land, and forbade Mr. Lake, one of the contractors, from proceeding further with the work until the matter should be definitely understood. Mr. Lake, an experienced contractor, suggested that the parties make a party wall of it, and make a mutual agreement covering the subject, to which both Frank Heaton and the complainants assented, and such an agreement was orally made by Frank Heaton and Mr. Lake, acting for complainants, by which it was provided, among other things, that the wall should be a party wall, having its center on the line then determined upon, and marked by a nail driven in the sidewalk. This nail was to be, and actually was, 14 feet and 7-]- inches east from the east wall of Bennett’s building, located on the lot next west of the defendant’s. It was understood between Frank Heaton and the complainants that the oral agreement thus made should be put into the form of a written contract to be signed and executed by the parties. The complainants, however, did not wait for this to be done, but proceeded with the work of construction, and located the wall with its center at the point and on the line so agreed upon. This oral agreement was made some time in October, and, before any written agreement with reference to tho party wall was executed, the complainants and Neesley had completed the brick building. On the 7th day of November, 1893, a written contract was prepared by Judge Lewis M. Powell, which was finally executed by complainants and defendant, by Frank Heaton, his attorney-in-fact, on the 26th day of February, 1894. This contract located the west line of the party wall “fourteen feet seven and one-half inches easterly, by the line of Main street, from the east side of the brick wall of the adjoining building, owned by Charles E. Bennett.”
*208So far we have taken our statement from the brief of defendant’s counsel, from which it clearly appears: First, that there was an oral agreement that the center line of the division wall was to be 14 feet 7-J- inches from the east side of the Bennett building; second, that it in fact was so placed; third, that, after it was so placed, the party-wall agreement was executed, which did not accord with the parol agreement.
The testimony of the county surveyor establishes the fact that the division line as fixed by actual occupancy for more than the statutory period was still less favorable to the defendant than the parol agreement and actual location of the wall, and that by the parol agreement the defendant actually gained 3-J inches, and that, if the written contract is to stand, he will gain about 13|- inches. We are also convinced that the complainants and defendant’s agent understood, at the time of the execution of the written agreement, that it did not fix the boundary line different than it had been fixed by the oral agreement and actual location of the wall.
At the close of the testimony, complainants were permitted to amend their bill by adding an alternative prayer as follows:
“Or that the defendant be perpetually enjoined from maintaining the said ejectment suit, and that he be required to pay to complainants one-half the cost of such wall within a reasonable time, and that the center of such wall be declared to be the boundary line between the lands of said defendant and said William Breitmayer, and that the said written agreement be set aside and annulled.”
The circuit judge granted the relief prayed, and defendant appeals.
Defendant contends that by the amendment to the bill it was made multifarious. It is conceded that a bill may have a double aspect and an alternative prayer if the two prayers are not inconsistent, but it is claimed-that these prayers are inconsistent. We do not think *209the eases cited1 are controlling, and we do not discover any inconsistency in the prayers. Both the original bill and the amended prayer prayed for an injunction restraining the prosecution of the suit in ejectment, and prayed that the center line of the wall be declared tbe boundary line between the two properties. It is true, the original prayer was for a reformation of the instrument, and the amended prayer asks that it be set aside; but in either case it is asked that the legal rights of the parties to the property be declared in the same terms. The amendment was probably intended to meet a possible difficulty arising out of want of authority in the agent to execute any other than the agreement actually signed.
On the merits the equities are very clearly with the complainants. It is manifest that complainants did not intend to grant away the partition wall already constructed, nor did the agent of defendant understand that his principal was acquiring it.
It is contended that complainants are not entitled to relief, because they failed to ascertain the authority of defendant’s agent, which was in fact limited to the execution of the instrument as written. The complainants may have taken the risk of the agent’s authority, but in doing so they did not bind themselves to an undertaking to which they never intelligently assented, unless they are guilty of such culpable negligence as debars them, or are estopped by their conduct. We are satisfied that complainants should not be held barred by their negligence, inasmuch as no action by defendant with reference to the possession of this land has been induced by their laches. 2 Pom. Eq. Jur. § 856. Nor is there any element of estoppel. The defendant has parted with nothing on the strength of complainants’ mistake. Id. § 870. If the agreement were wholly canceled, the rights of the parties would be determined by their previous undisputed occu*210pancy and tbe verbal agreement, and the rights accorded by the decree are only those to which the complainants are entitled.
The decree is sufficiently favorable to defendant, and is affirmed, with costs.
