In Riverton Assocs. v. Knibb, 11 Misc 3d 14 (App Term, 1st Dept 2005) the granddaughter of the tenant of record moved into the apartment in 1991 to care for her infirm grandmother. The grandmother died in 1999. But instead of notifying the landlord, the granddaughter concealed her grandmother's death and went so far as to forge her grandmother's signature on two renewal leases. Nonetheless, in light of the granddaughter's persuasive showing of co-occupancy and because the granddaughter's misrepresentations were "relatively short-lived," "any fraud or irregularities committed in the aftermath of the grandmother's death cannot reasonably be said to have caused petitioner any discernible prejudice in the prosecution of its eviction claim."
