This is an action of contract for commissions upon rent collected and sales of land belonging to the defendant’s testator. The services were rendered upon a written contract and the amount of the charge is not disputed. The case is here upon the defendant’s exception to the refusal of the Superior Court to rule that the plaintiff was estopped from maintaining this action, and that is the only question before us. The case was presented to the Superior Court upon an auditor’s report and certain evidence to be taken as agreed facts with power to draw inferences, so that the question stated in a different form is whether we can say as matter of law that the Superior Court was wrong in finding that the plaintiff was not estopped.

The defendant is ancillary administrator, his intestate’s executrix being the widow in England. It appears that the plain"tiff had paid over the rent and the proceeds of one sale to the testator during his lifetime, without deduction, and being called on by the defendant for an account of rents received, presented one in which nothing was said as to commissions. The plaintiff’s statement was accepted, he paid the money, and the defendant tendered releases of all claims for rent, reciting that the sums received were the sums due as the executrix’s share of the rents, profits and income of the real estate upon an accounting *242together. There were two accounts involved, and the plaintiff, professing to wish releases on separate papers, offered two to the defendant for signature, saying that they were substantially in the form, drawn by the defendant, and the defendant executed them without noticing that the mention of an accounting together had been left out. Other land was sold through the plaintiff in the same month. Afterwards the plaintiff, who thus far had been purposely silent as to commissions, sent in his bill. The auditor found that the plaintiff had waived any claim for compensation, but the Superior Court found the other way.

It is manifest that the first inclination of a tribunal of fact would be to find for the defendant, as the auditor did. We shall not undertake to say that in all the facts of the case enough might not have been found to warrant that conclusion, although the consideration was executed and there was no release. See Gingrass v. Iron Cliffs Co. 48 Mich. 413; Oil Co. v. Van Etten, 107 U. S. 325. But whether that be so or not, we cannot say that the judge of the Superior Court was wrong. We cannot say that he was not warranted in finding that the defendant was at arm’s length with the plaintiff, in finding that the defendant did not rely upon the plaintiff’s statement as to the contents of the substituted releases and must be charged with knowledge of the altered form of the documents which he signed and probably read. Proceeding upon the same grounds, the judge might have found that the plaintiff, in the figures which he gave and in his silence as to a counterclaim, was standing on his rights as an adverse party dealing with people with whom his relations were avowedly unpleasant, that he was at liberty to present his claim when he chose, and that the defendant was entitled to assume nothing more than that the account was a true account of the plaintiff’s receipts. The judge might have found that there was no reliance in fact upon the plaintiff’s conduct other than that specifically mentioned and agreed to in the exceptions. For all that appears the defendant may have been chargeable with notice of his intestate’s contract. It is to be observed that the largest items in the plaintiff’s charge are commissions on sales, while the account and releases dealt only with rents. See further Ryan v. Rand, 6 Foster, 12. Payment of the full rent by the plaintiff after making his contract with the testator did *243not necessarily import that there was not a counterclaim even in respect of that. Moulton v. McOwen, 103 Mass. 587, 598.

It is not argued that the judge was bound by the finding of the auditor, if that question were open on the exception. Connolly v. Sullivan, 173 Mass. 1. Emerson v. Patch, 129 Mass. 299. Hamilton v. Boston Port & Seamen’s Aid Society, 126 Mass. 407. Peru Steel & Iron Co. v. Whipple File & Steel Manuf. Co. 109 Mass. 464, 466. Compare Goodell v. Goodell, 173 Mass. 140, 146.

Exceptions overruled.
