When Roger grants his best friend Louis authority to list and negotiate for his house, what type of agent is Louis considered?

When Roger grants Louis the authority to list and negotiate for his house, Louis is considered a special agent. A special agent is someone who is given specific authority to act on behalf of another person (the principal) for a particular task or transaction, in this case, the listing and selling of a house.

This type of agency is limited in scope, and the authority granted is confined to the task specified—in this situation, the sale of the property. Unlike a general agent who might have broader responsibilities and continuous authority over various matters, or a universal agent who has the authority to act on behalf of another across a wide range of affairs, Louis's role is specific to the real estate transaction at hand.

Implied agents are usually recognized through the context of the relationship and actions, but in this case, the relationship is clearly defined through the agreement. Thus, in the context of selling a home, Louis's role as a special agent highlights the limited and focused nature of the authority he has received from Roger.
