Michigan Compiled Laws, Chapter 449. Partnerships § 449.1104

Sec. 104. (a) A domestic limited partnership may transact its business under any assumed name or names other than its name as set forth in its certificate of limited partnership and a foreign limited partnership may transact its business under any assumed name or names other than the name under which it has registered in this state if not precluded from use by section 102(2), (3), (4), or (5),  1 and the same name may be assumed by 2 or more domestic or foreign limited partnerships participating together in any partnership or joint venture by filing with the administrator a certificate stating the name as set forth in the certificate of limited partnership, in the case of a domestic limited partnership, or under which it has registered in this state, in the case of a foreign limited partnership, and the assumed name under which the business is to be transacted. Such certificate shall be effective for a period expiring on December 31 of the fifth full calendar year following the year in which it was filed, unless sooner terminated by the filing with the administrator of a certificate of termination of assumed name or by the dissolution and the commencement of winding up of a domestic or foreign limited partnership or the filing with the administrator of a certificate of cancellation of registration of a foreign limited partnership. It may be extended for additional consecutive periods of 5 full calendar years each by the filing with the administrator of similar certificates not earlier than 90 days preceding the expiration of any such period. The administrator shall notify the limited partnership of the impending expiration of the certificate of assumed name no later than 90 days before the initial or subsequent 5-year period will expire. This section does not create substantive rights to the use of a particular assumed name.

(b) Each certificate filed pursuant to section 104(a)  2 shall be executed by at least 1 general partner.
