How to file through the authority

RSA 349:5 describes the filing itself: a certificate filed in the office of the secretary of state, signed by the proprietor or by the members of the partnership or association, stating the name under which the business is to be conducted, its principal place of business, a brief description of the kind of business, and the names and addresses of the principal parties.

Official sources and supporting excerptsSource: www.gencourt.state.nh.us official record · retrieved
  • Every sole proprietor doing business in this state under any name other than the sole proprietor's own name, and every partnership, trust or association doing business in this state shall register the trade name of such business, trust or association in the manner provided in RSA 349:5 and 349:6.
  • Every person, proprietorship, partnership, or association, as defined in RSA 349:1, engaged in the conduct of any business, enterprise, venture, or activity within the state of New Hampshire under a trade name, firm, or style shall, subject to the limitations hereinafter set forth, file in the office of the secretary of state a certificate signed by such person, proprietorship, or by the members of such partnership or association stating the name under which the business is to be conducted, the principal place of said business, and a brief description of the kind of business to be carried on with the names and addresses of the principal parties engaged therein.

The statute sets the registration fee at $50, paid to the secretary of state for filing the registration and issuing a certificate of registration.

Renewal, amendment, and abandonment

A registration takes effect on filing and continues for 5 years after the filing date unless it is withdrawn or discontinued earlier, and the registrant is required to reregister when that 5-year period expires.

  • Every person, proprietorship, partnership or association registered in accordance with the requirements of this subdivision shall be required to reregister at the time of the expiration of the 5-year period set forth in RSA 349:6.

Publication and notice

Publication could not be confirmed for all covered entity types. No requirement or exemption is asserted.

Next steps: self-file first

Start with the statute’s own checklist: the trade name, the principal place of business, a brief description of the business, and the names and addresses of the principal parties, then budget the $50 registration fee.

  • Every person, proprietorship, partnership, or association, as defined in RSA 349:1, engaged in the conduct of any business, enterprise, venture, or activity within the state of New Hampshire under a trade name, firm, or style shall, subject to the limitations hereinafter set forth, file in the office of the secretary of state a certificate signed by such person, proprietorship, or by the members of such partnership or association stating the name under which the business is to be conducted, the principal place of said business, and a brief description of the kind of business to be carried on with the names and addresses of the principal parties engaged therein.
  • There shall be paid to the secretary of state for filing of registration and issuance of certificate of registration a fee of $50.

Diary the 5-year term, because the statute requires reregistration at expiration and treats a registration that is not renewed as discontinued and the name as abandoned.
