A New York Affidavit of Service (After Commencement) is a sworn statement that a legal document has been served to an individual party or parties. It is used to prove that the document was served legally and to satisfy the law’s requirements that the document be served in a particular manner. There are two types of New York Affidavit of Service (After Commencement): personal service and substituted service. Personal service is when a legal document is served directly to the party by an individual who is not a party to the action. The individual serving the document must be at least 18 years of age and must have a valid New York State ID. The affidavit must be completed by the server, who must include details such as the date and time the document was served, the name of the person served, and how it was served (in person, by mail, etc.). Substituted service is when a legal document is served to someone other than the party, such as an adult relative or an employee of the business or organization where the party is employed. The affidavit must be completed by the server, who must include details such as the date and time the document was served, the name of the person served, and how it was served (by mail, left with an adult relative, etc.). In both cases, the New York Affidavit of Service (After Commencement) must be signed under penalty of perjury and notarized. It must then be filed with the court and served on the parties.
