The New York Bulk Purchase of Index Number Agreement (CIV-AD-79) is an agreement between two or more parties that allows for the bulk purchase of index numbers from the NYS Department of State. The Index Number is an assigned number used to identify a document filed in a county clerk's office. The agreement allows parties to purchase a predetermined number of index numbers in bulk, which can then be used for filing documents in the county clerk's office. There are two types of the New York Bulk Purchase of Index Number Agreement (CIV-AD-79): an individual version and a business version. The individual version allows for the purchase of index numbers in bulk for one person or entity, while the business version allows for the purchase of index numbers in bulk for multiple entities. Both versions provide parties with the right to use the purchased index numbers to file documents in the county clerk's office.
