A New York Certificate of Discontinuance of Business is a document that legally confirms the termination of a business in New York. This document is filed with the New York Department of State to provide public notice that the business is no longer operating in the state. The certificate is generally filed as part of the dissolution process for a business. There are two main types of New York Certificate of Discontinuance of Business: Certificate of Discontinuance of Domestic Business and Certificate of Discontinuance of Foreign Business. The Certificate of Discontinuance of Domestic Business is filed by a business that is incorporated or registered in New York and is ceasing operations in the state. The Certificate of Discontinuance of Foreign Business is filed by a business that was formed outside of New York and has been conducting business in the state, but is now dissolving its presence in the state. The Certificate of Discontinuance of Business must be signed, notarized, and filed with the New York Department of State to be valid.
