Trade Name Certificates

Trade Name Certificates

Under Connecticut General Statute 35-1, "No person…shall conduct or transact business in this state, under any assumed name, or under any designation, name or style, corporate or otherwise, other than the real name or names of the person or person conducting or transacting such business, unless there has been filed, in the office of the town clerk in the town in which such business is or is to be conducted, a certificate, stating the name under which such business is being transacted and the full name and post-office address of each person conducting or transacting such business."

The cost for such a trade name certificate is $10.00. A copy of the form may be accessed here (pdf format, may be filled out before printing).  Please, do not pre-sign the trade name certificate.  The certificate must be signed in the presence of the Town Clerk staff OR by using a notary public.
