A New York Reply Affidavit is a legal document used in the state of New York to respond to a summons or complaint. It is a written statement under oath that is used to dispute the claims made by the plaintiff in the case. The affidavit must be signed by the defendant and sworn before a notary public. There are two types of New York Reply Affidavits: one for civil cases and another for criminal cases. In a civil case, the defendant is generally required to provide a detailed explanation of why they deny the plaintiff's allegations. In a criminal case, the defendant is generally required to provide a general denial of the charges, or to provide information about any defenses they may have.
