The New York Affirmation of Non-Expiration of Statute of Limitations is a document that is used to extend the Statute of Limitations on a particular claim or action. This document is used to affirm that the Statute of Limitations will not expire on the claim or action, and that the claimant or plaintiff is still able to pursue the claim or action even though the Statute of Limitations has lapsed. There are four main types of New York Affirmation of Non-Expiration of Statute of Limitations: the Statute of Limitations Affidavit, the Acknowledgment of Service, the Certificate of Service, and the Notice of Intent to Sue. The Statute of Limitations Affidavit is used as evidence that the Statute of Limitations has not expired on the claim or action in question. The Acknowledgment of Service is a document that is signed by the defendant, acknowledging that they have been served with a document regarding the claim or action. The Certificate of Service is a document that is signed by the court clerk, confirming that the defendant was served with the required documents. The Notice of Intent to Sue is a document that is sent to the defendant to inform them of the claimant’s intent to pursue the claim or action.
