Law of agency

Person representing another person in legal matters, and the laws enabling this

The law of agency is an area of commercial law dealing with a set of contractual, quasi-contractual and non-contractual fiduciary relationships that involve a person, called the agent, who is authorized to act on behalf of another (called the principal) to create legal relations with a third party. It may be referred to as the equal relationship between a principal and an agent whereby the principal, expressly or implicitly, authorizes the agent to work under their control and on their behalf. The agent is, thus, required to negotiate on behalf of the principal or bring them and third parties into a contractual relationship.
