A. Every manager is an agent of the limited liability company for the purpose of its business, and the act of every manager, including the execution in the limited liability company name of any instrument for apparently carrying on the business of the limited liability company of which he is a manager, binds the limited liability company, unless the manager so acting lacks the authority to act for the limited liability company in the particular matter, and the person with whom he is dealing has knowledge of the fact that he has no such authority. The unauthorized acts of the manager shall bind the limited liability company as to persons acting in good faith who have no knowledge of the fact that the manager had no such authority.

B. Subject to the provisions of subsection A of this section and Section 2019.1 of this title, instruments and documents providing for the acquisition, mortgage, or disposition of real or personal property of the limited liability company shall be valid and binding upon the limited liability company if executed by one or more of its managers.
