A New York Affidavit of Service is a sworn written statement by a person who has served legal documents, such as a summons, complaint, or motion. It is used to provide proof that legal documents were properly served and delivered to the other party in a legal case. There are three main types of New York Affidavit of Service: personal service, service by mail, and service by publication. For personal service, the server must personally deliver the documents to the other party, and then sign an affidavit of service to confirm that they have done so. For service by mail, the server must mail the documents to the other party, and then sign an affidavit to confirm that they have done so. For service by publication, the server must publish the documents in a newspaper of general circulation, and then sign an affidavit to confirm that they have done so. In all cases, the New York Affidavit of Service must be signed and notarized by the server and submitted to the court as proof of service. It should include information such as the date and time the documents were served, the name of the person served, and the method of service used.
