1. (a) No person, except as provided in this subsection, 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 persons 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 or transacted, a certificate stating the name under which such business is or is to be conducted or transacted and the full name and post-office address of each person conducting or transacting such business or, in the case of a corporation or limited liability company using such an assumed name, its business name, business identification number and principal office address as reflected on the records of the Secretary of the State. Such certificate shall be executed by all of such persons or, in the case of a corporation or limited liability company, by an authorized officer thereof, and acknowledged before an authority qualified to administer oaths. Each town clerk shall keep an alphabetical index of the names of all persons filing such certificates and of all names or styles assumed as provided in this subsection and, for the indexing and filing of each such certificate, shall receive the statutory filing fee for documents established in section 7-34a, to be paid by the person filing such certificate. The Secretary of the State shall create an electronic system to collect from each town clerk the trade name index information required by this section. A town clerk shall be deemed to have complied with the index information requirement set forth in this subsection, if the Secretary determines that the index information provided by such town clerk contains all active trade name records on file with such clerk. A copy of any such certificate, certified by the town clerk in whose office the same has been filed, shall be presumptive evidence, in all courts in this state, of the facts contained in such certificate. The provisions of this subsection shall not prevent the lawful use of a partnership name or designation if such partnership name or designation includes the true surname of at least one of the persons composing such partnership. This subsection shall not apply to:

   1. (1) Any limited partnership, as defined in section 34-9, provided such limited partnership (A) has (i) filed a certificate as provided for in section 34-10, or (ii) registered with the Secretary of the State as provided in section 34-38g, and (B) conducts or transacts business under the name stated in the certificate or registered with the Secretary of the State, or (2) any limited liability company, as defined in section 34-243a, provided such limited liability company (A) has (i) filed articles or a certificate of organization as provided for in sections 34-243i and 34-247, or (ii) registered with the Secretary of the State as provided in sections 34-243m, 34-275a and 34-275b, and (B) conducts or transacts business under the name stated in the articles of organization or registered with the Secretary of the State. Any person conducting or transacting business in violation of the provisions of this subsection shall be fined not more than five hundred dollars or imprisoned not more than one year. Failure to comply with the provisions of this subsection shall be deemed to be an unfair or deceptive trade practice under subsection (a) of section 42-110b.

2. (b) No person shall use, in any printed advertisement, an assumed or fictitious name for the conduct of such person's business that includes the name of any municipality in this state in such a manner as to suggest that such person's business is located in such municipality unless:

   1. (1) Such person's business is, in fact, located in such municipality; or (2) such person includes in any such printed advertisement the complete street address of the location from which such person's business is actually conducted, including the city or town and, if located outside of Connecticut, the state in which such person's business is located. This subsection shall not apply to the use of (A) any trademark or service mark registered under the laws of this state or under federal law, (B) any such name that, when applied to the goods or services of such person's business, is merely descriptive of them, or (C) any such name that is merely a surname. A violation of the provisions of this subsection by a person conducting business under an assumed or fictitious name that includes the name of a municipality in this state shall be deemed an unfair or deceptive trade practice under subsection (a) of section 42-110b. Nothing in this subsection shall be construed to impose any liability on any publisher that relies on the written assurances of a person placing such printed advertisement that such person has authority to use any such assumed or fictitious name.
