Principal (Agency Law)

A principal is a person or entity who authorizes another party, called an agent, to act on their behalf. The principal holds the underlying authority, sets the limits of the agent's role, and bears legal responsibility for the agent's authorized actions.

How a principal works

A principal-agent relationship is created when one party grants another the authority to act in their name. That authority can be broad or narrow, written or implied, and temporary or ongoing.

The principal defines the scope of the agent's authority. Any agreements or decisions the agent makes within that scope are generally binding on the principal. The relationship ends when the task is complete, the authorization is revoked, or the principal dies or becomes incapacitated, depending on the type of authority granted.

Key characteristics

• Legal capacity to delegate: The principal must have the legal authority to delegate. A minor generally cannot serve as a principal in a binding legal arrangement.
• Accountability for authorized actions: Third parties dealing with an agent in good faith can generally hold the principal to those dealings.
• Control over scope: The principal defines the limits of the agent's authority through a written document, oral agreement, or the circumstances of the relationship.
• Right to revoke: The principal can typically terminate the agency relationship at any time, unless the authority is coupled with an interest that limits the principal's right to revoke.

Common uses

• Power of attorney: The person who creates a power of attorney is the principal. They authorize an agent (also called an attorney-in-fact) to manage financial or healthcare decisions on their behalf.
• Business agency relationships: A business owner who hires a sales representative to negotiate contracts is the principal. Any binding agreement the representative signs within their authorized scope is enforceable against the owner.
• Real estate transactions: A property seller who engages a real estate broker is the principal. The broker acts as agent, but the seller retains ownership and final decision-making authority.
• Corporate settings: Shareholders are sometimes described as principals who delegate management authority to officers and directors.

Related terms

FAQs about principal

Can a principal be liable for actions the agent took without permission?

Yes, in some cases. If a third party reasonably believed the agent had authority, the principal may be bound by those actions even without actual authorization. Documenting the scope of authority in writing is one of the most important protections a principal can put in place.

What happens to a power of attorney if the principal becomes incapacitated?

A standard power of attorney terminates automatically upon the principal's incapacity. A durable power of attorney is drafted specifically to survive incapacity and is the appropriate choice for long-term estate planning.
