This motion is made by the defendants, Koch & Jacob, to open a judgment entered by default against them November 9, 1878. It is based upon an error of fact not arising upon the trial and falls, therefore, within section 1290 of the Code of Civil Procedure. By the terms of the contract of sale they were not to assume the mortgage in question ; and the covenant in the deed which imposed this liability upon them was a mutual mistake between the parties thereto, for the contract was in writing and there is nothing to show that there had been any change in its terms, in pursuance of which the. deed should have been drawn. Hot having the contract at hand when the foreclosure was had the defendants rightfully suffered a default, but when the discovery of the contract showed their non-liability for the deficiency they then had the right to resist the responsibility which they had unknowingly assumed. Suppose the recital of the amount of the mortgage in the deed had exceeded the amount of that named in the contract, would the former control and leave the defendants without any redress % There is no principle of equity that would sustain such a proposition. The defend; ants are entitled to their defense (Kilmer agt. Smith, 77 N. Y., 226). Nor can I understand how a stipulation, to which "these defendants were not parties, could change the order of payment of the liability of the defendants who were responsible for the deficiency.
According to the usual practice the liability was both joint and several, and I cannot understand from the papers submitted how the defendant Merritt has become a guarantor for these defendants. If he had paid the claim he might claim contribution, but he cannot insist, by virtue of any legal *228right, that a newly-discovered and meritorious defense may not he interposed to an alleged personal liability^ where the laches are satisfactorily explained and the foreclosure proceedings proper are not impugned or "delayed.
Motion granted on payment of costs; order to be settled, on notice, July twentieth at 11 a. m.
