It is contended that at the time of the making of the contract the defendants were not the owners of any interest in the land who entered into the contract for the improvement thereof within the meaning of sec. 289.01 (1) (c), Stats., and that, therefore, plaintiff has no valid claim for a mechanic’s lien. Assuming that, as defendants contend, they had no interest in the premisеs at the time of the making of
*254
the contract because it was not in writing, that fact would not be fatal to plaintiff’s claim for a mechanic’s lien. The plaintiff was not required to prove what interest the defendants had in the premises at the timе of the making of the contract. When the lien is enforced it is enforced only upon the interest of the defendants in thе real estate and should it transpire that the latter have no such interest, the plaintiff would take nothing by his judgment.
Willer v. Bergenthal
(1880),
If defendants hаd no interest in the property prior to March 5, 1951, they acquired one however by virtue of the deed given them on that date. The lien attaches to that after-acquired interest.
“Sec. 289.12 Judgment. The judgment shall adjudge the amount due to each claimant who is a party to the action. It shall direct that the interest of the owner in the premises at the commеncement of the work or furnishing the materials for which liens are given and which he has since acquired, . . .” (Italics ours.) See also Hawley v. Tesch (1894),88 Wis. 213 ,59 N. W. 670 , and annotation in 85 A. L. R. 928.
Defendants contend that, by execution of the deеd referred to, plaintiff is estopped to assert a claim for mechanic’s lien and also that thereby he has waived his right thereto. The doctrine of estoppel does not' operate against one unless he has done sоmething to induce another to change his position to his prejudice.
Wyman v. Utech
(1949),
Defendants state as one of the questions involved that “the warranty deed given by the plaintiff and conveying lands owned by him was in fact a sale of the lands in question.” If the statement is to be construed as meaning that the entire agreement was merged in the deed the contention is without merit. The defendants agree that it was understood that they should have the deed and that its execution and delivery constituted only one of the acts to be performed by plaintiff.
Defendants urge that we treat the item of “five per cent for supervising and miscellaneous sеrvices” as a provision for payment of a real-estate broker’s fee, and contend that plaintiff may not recover it because he is not a licensed real-estate broker or salesman. The testimony upon this point is nоt conclusive one way or the other, although it appears to us that plaintiff’s activity with respect to a loаn obtained by defendants and secured by a mortgage was of no great consequence. The trial court made nо finding upon the subject. The burden of proving the defense was upon the defendants. They failed to meet it, at least they fаiled to establish what, if any, of the five per cent was charged as a fee for broker’s services.
Defendants contend that the court erroneously allowed an inclusion in the recovery of some items of overhead expense in computing the cost of labor furnished. The issue was not raised by the pleadings. No request was made for a finding upon the subject and none was made. To consider defendant’s contention would require that we ascertain what sum or sums were actually paid to plaintiff’s various employees and what amounts, if any, were charged to defendants for ovеrhead. The record is not in such shape as to have enabled the trial court to make the computation, аnd it follows, of course, that we are unable to do so. True, plaintiff testified that he *256 hired an employee by the weеk without indicating or being asked what salary was paid him and for how many hours per week, and that he paid the man $1.50 per hоur, suggesting that possibly (but only possibly) less than $1.50 per hour was paid, but the trial court could not have so found upon the recоrd before it.
Finally, defendants contend that the amount of the recovery should be reduced because some of the elements in plaintiff’s claim were allowed without having been itemized. In his complaint plaintiff alleged that the total amount due under his contract is $10,991, $7,575 has been paid, and that there is now owing a balance of $3,416. He did not itemize his acсount in his testimony given at the trial. No bill of particulars was demanded by defendants. Defendants themselves offered in evidenсe Exhibit 4, a statement of charges and credits consisting of eight pages and manifestly prepared by the plaintiff. It is a detailed statement of the materials furnished and states a lump sum of $1,858.07 for carpenter labor furnished. It was stipulated at the suggestion of defendants, that it represents “items set forth on slips presented by plaintiff to defendants” and was receivеd in evidence. Upon his cross-examination of plaintiff, counsel referred to a slip which had been given defendants by plaintiff; plaintiff testified that it is a “summary of carpenter labor in connection with the construction” and that the total amount stated on the exhibit is $1,858.07, the exact amount which is carried in Exhibit 4 for carpenter labor. It does not appear that the issue was raised in the court below or that the defendants requested a finding upon the subject. No finding was made. Thеre is no suggestion in the record that it was raised in the court below or that the court’s attention was called to it. Consequently, it is not here for determination.
