Who must file a business certificate?
Massachusetts General Laws Chapter 110, 5 states that any person conducting business under any title or business name other than the real name of the person conducting the business must file a certificate. A person is defined as an individual, a partnership, or a corporation.


Exemptions to filing are allowed under 6 if the corporation is doing business in its true corporate name, or if a partnership is doing business under any title which includes the true surname of any partner. Certain other exemptions exist for trusts and limited partnerships.
