ALTHOUGH DOCUMENTARY EVIDENCE IS ADMISSIBLE NOTWITHSTANDING THE DEAD MAN’S STATUTE, HERE THE DECEDENT’S SIGNATURE ON THE GUARANTY WAS NOT AUTHENTICATED BY SOMEONE OTHER THAN AN INTERESTED WITNESS; THEREFORE PLAINTIFF’S MOTION FOR SUMMARY JUDGMENT ON THE GUARANTY SHOULD NOT HAVE BEEN GRANTED (FIRST DEPT).

The First Department, reversing (modifying) Supreme Court, determined the personal guaranty signed by decedent was not authenticated. Therefore plaintiff was not entitled to summary judgment on the guaranty:

We modify, however, with respect to the cause of action under the personal guaranty purportedly signed by the decedent, because although documentary evidence is admissible notwithstanding the dead man’s statute, it must be “authenticated by a source other than an interested witness’s testimony” … . Having failed to authenticate the guaranty through “a source other than an interested witness’s testimony,” plaintiff was not entitled to summary judgment on the guaranty. Galpern v Air Chefs, L.L.C., 2020 NY Slip Op 01021, First Dept 2-13-20
