The short answer is “none.”
The Registered Agent has no position within the company, and no power. The Registered Agent’s job is to forward service of process to a Company’s designee, whether a Manager, Owners, Board or other authorized representative of the company.
Therefore, a Registered Agent cannot enter into a contract on behalf of the company.
A Registered Agent cannot issue “powers of attorney”.
A Registered Agent cannot even indicate who owns a company.
This is not to say that someone WITH power in a company, such as an owner, president, secretary or even attorney-in-fact, can also be the Registered Agent for the company. In such instances, the person wielding power on behalf of the company is doing so not as the company’s Registered Agent, but because of some other office or position within the company.
