A New York Affidavit of Service is a sworn document used in New York courts to prove that a party has been properly served with a legal document. It includes a declaration by the person who served the documents (the server) that the documents were delivered to the other party in accordance with the New York Rules of Civil Procedure. It also includes specific information about when, where, and how the documents were served. There are two types of New York Affidavit of Service: one for personal service and one for service by mail. For personal service, the server must provide detailed information about the time, date, and location of the service, as well as the name of the person who accepted service. For service by mail, the server must provide details about when the document was mailed, the type of mail used, and the address where it was mailed.
