A New York Reply Affidavit is a type of sworn document filed in New York courts in response to a summons or complaint. It is a legal document that allows the responding party to state their defense or explanation in a suit. There are two types of New York Reply Affidavits: an Answer and a Counterclaim. An answer is a response to the plaintiff's allegations, while a counterclaim is a claim made by the defendant against the plaintiff. Both Answer and Counterclaim affidavits must include a sworn statement of truth and must be signed and notarized. The reply affidavit must be filed with the court within twenty days of receiving the summons or complaint.
