New York Residential Cooperative Unit Affidavit is a legal document that is used to transfer the ownership of a residential cooperative unit from one party to another. The affidavit is typically signed by the seller, and it outlines the terms and conditions of the sale and transfer of ownership. It also includes a statement of the seller's financial responsibility and warranty as to the title of the unit. There are two types of New York Residential Cooperative Unit Affidavit: the Disclosure Affidavit and the Limited Warranty Affidavit. The Disclosure Affidavit contains a detailed description of the unit, including the address, monthly maintenance fees, and any restrictions on the unit. The Limited Warranty Affidavit provides limited warranties to the buyer regarding the title of the unit, the existence of the unit, and the accuracy of the information provided in the Disclosure Affidavit.
