A New York Affidavit of Service is a document used to prove that legal documents were properly served on a party in the state of New York. It is typically required for court-related proceedings. The document must be signed before a notary public, and it must include the name of the person served, the date and time of service, the manner of service, and the name and address of the person who performed the service. There are two main types of New York Affidavit of Service: affidavit of personal service and affidavit of substituted service. An affidavit of personal service is used when legal documents are delivered to the person in person. An affidavit of substituted service is used when legal documents are delivered to a third party at the person's residence or place of business.
