This is a suit in equity by alleged tenants of real estate against the mortgagee and the owner of the equity of redemption, wherein the plaintiffs offer to take over the mortgage and seek to restrain its threatened foreclosure and to obtain recognition of their rights as tenants. The case was heard by a judge of the Superior Court, who made findings of fact and entered a decree dismissing the bill. The plaintiffs’ appeal brings the case here.
The evidence is not reported and therefore the findings of fact must be accepted as final. The question is whether the decree rightly was entered on the facts found. First Baptist Society in Brookfield v. Dexter, 193 Mass. 187, 189.
The premises here in question, together with adjoining premises, were owned by Mrs. Hayes and one Brosnan as tenants in common. The husband of Mrs. Hayes collected rents, made repairs, and paid taxes and mortgage interest. In 1917 Brosnan was adjudged to be insane and his temporary guardian permitted Hayes to continue as before. In October, 1919, Hayes executed a lease of a part of the premises here in question to one of the plaintiffs for a term of five years from November 1, 1919, and on March 1, 1920, he executed a lease of another part for a term of five years from that date to the other plaintiff. The guardian of Brosnan did not authorize these leases and, as soon as he knew of them, wrote to the tenants that he had not signed nor assented to the leases and that they must govern themselves accordingly. On March 24, 1920, the defendant Charles H. Wentworth bought the undivided half of the property previously owned by Brosnan and by partition proceedings became the sole owner of the prem*379ises here in question on September 21, 1921. Hayes continued to collect rents and make disbursements on account of the property until May, 1921, and thereafter a receiver had charge until November, 1921. The plaintiffs regularly paid the rent as reserved in their leases to Hayes and the receiver.
Charles H. Wentworth had an accounting with Hayes and with the receiver wherein the amount of rent received monthly from each of the plaintiffs was stated. There is nothing to indicate that he knew that the plaintiffs were claiming to hold as lessees under written leases. The facts found do not require that inference. His acceptance of rent without knowledge of the existence of the leases or of the claims of the plaintiffs does not make thé leases valid as to him. There are no facts found which constitute as matter of law ratification or approval of the leases by Charles H. Wentworth. Cases like Nelson Theatre Co. v. Nelson, 216 Mass. 30, and Gross v. Cohen, 236 Mass. 468, are clearly distinguishable. The finding of fact in the case at bar is that there was no ratification. The plaintiffs were in occupation of their respective tenements and would be expected to pay for the use. Mere acceptance of rent by the defendants does not constitute ratification of the leases. Lamson v. Coulson, 234 Mass. 288, 296.
There is nothing in this record which prevents the defendants from asserting their rights. In order to work an estoppel, one must be induced by the conduct of another to do something which otherwise would not have been done and which has resulted in his harm and that the other knew or had reasonable cause to know that such consequences might follow. Whether estoppel exists, or not, is a question of fact where more than one inference is possible. Boston & Albany Railroad v. Reardon, 226 Mass. 286, 291. The entry of the decree dismissing the bill imports a drawing of all rational inferences against the plaintiffs so far as necessary to that result.
Decree affirmed with costs.
