The New York RP-5217 Sale Correction Form-Transmitt To CORPS By County Director is a form used by county directors to report changes to real estate transactions in the state of New York. This form is required for any corrections to information previously reported to the Office of Real Property Services (CORPS) as part of the Real Property Transfer Report (RP-5217). There are three types of RP-5217 Sale Correction Forms: RP-5217-C (Correction Form), RP-5217-A (Additional Property Form), and RP-5217-S (Substitute Form). All three forms must be completed and submitted to CORPS by the county director to make changes to real estate transactions. The form requires details such as the address of the property, the names of the buyers and sellers, and the amount of the sale. Correcting changes on the RP-5217 Sale Correction Form is necessary to ensure accuracy of the real estate transaction and to avoid any penalties or fees.
