The New York Certificate of Assumed Name is a document filed with the county clerk’s office in each of New York State’s 62 counties by business entities that are using a name other than their true legal name. The certificate is also known as a “Doing Business As” (DBA) or “Fictitious Name” filing. There are three types of New York Certificate of Assumed Name: (1) Business Certificate, (2) Limited Liability Company Certificate, and (3) Partnership Certificate. A Business Certificate is filed by a sole proprietorship, corporation, or partnership for the purpose of conducting business in the state of New York under an assumed name. A Limited Liability Company Certificate is used by a Limited Liability Company to conduct business under an assumed name. Finally, a Partnership Certificate is used by a partnership to conduct business under an assumed name. All New York Certificate of Assumed Name forms must include the name and address of the entity filing the certificate, the assumed name being used, and the county in which the certificate is being filed.
