611.06(c) Signature by Joint Venture
Where a document must be signed by someone with legal authority to bind a joint venture, each party to the venture must sign. Although a joint venture has many attributes of a partnership, it is a special partnership, which is very limited in nature and scope. Generally, signature by each party to the joint venture is necessary.
In appropriate cases, a document filed by a joint venture may be signed by a general manager or other official rather than by each of the joint venturers, if the applicant or registrant states that the person who signed has legal authority to bind the joint venture under relevant state law.
