What is the role called of a person appointed to enter into a contract on behalf of another?

The role of a person appointed to enter into a contract on behalf of another is referred to as an agent. An agent acts on behalf of another party, known as the principal, to carry out specific tasks or make decisions. This arrangement allows the agent to execute actions, such as signing contracts, negotiating terms, and completing transactions, which the principal may not be able to do directly for various reasons, such as absence or expertise.

The concept of agency is foundational in both legal and business contexts, as it establishes a framework for delegating authority and responsibilities. Importantly, the agent must act in the best interest of the principal, following the guidelines or instructions provided, ensuring that the principal's needs and objectives are met effectively.

In contrast, roles such as executor, principal, or trustee involve different functions and responsibilities. An executor is typically responsible for administering a deceased person's estate according to their will. The principal is the party that delegates authority to the agent. A trustee manages assets on behalf of beneficiaries, often under a trust arrangement. Understanding these distinctions highlights the unique role of the agent in contractual and legal settings.
