Certificate of Discontinuance of Business Conducted Under Assumed Name

Many business owners, who have sole proprietorships, are under the false pretense that once you are out of business, there is no formal paperwork that needs to be filed; this is not so.

If you are a sole proprietor and are discontinuing your business you must file a "Certificate of Discontinuance of Business Conducted Under Assumed Name for an Individual."

As some businesses grow, and small partnerships end, many business owners are unaware that if the business partnership they formed is discontinued, they have to file a "Certificate of Discontinuance of Business Conducted Under Assumed Name for Partners."

  • No fee for filing a Certificate of Discontinuance.
  • Only the original discontinuance certificate must be submitted for filing. No additional copies necessary.
  • Must identify original certificate and amended certificate(s) (by BN#), if any, previously filed.
  • Must specify the date on which the discontinuance occurred or the conditions under which the business is conducted, changed so that the filing of a certificate is no longer required.
  • If partnership, must be executed by a majority of the persons named in the original certificate or the amended certificate last previously filed;
    • In the case of a corporation, by an officer of the corporation;
    • In the case of a limited partnership, by a general partner of the limited partnership; or
    • In the case of a limited liability company, by a member or manager of the limited liability company, or by an attorney-in-fact or authorized person for such corporation, limited partnership, or limited liability company, as the case may be.
  • If any partner is deceased, the discontinuance certificate shall so state and may be executed by a majority of the survivors, or by the executor or administrator (who has obtained letters testamentary or letters of administration) of a deceased person named in the original certificate or last previously filed amended certificate(s) as the only person conducting or transacting the business. If such signatures cannot be obtained, any such signatures may be dispensed with by order of the Supreme Court, Nassau County. Death certificate not required.
