What does agency law primarily concern?

Agency law primarily concerns the relationship between a principal and an agent, focusing on how one party (the agent) is authorized to act on behalf of another party (the principal). This legal framework establishes the rights, duties, and obligations that arise from this relationship. It encompasses how the agent can bind the principal to contracts and act in the principal's best interests, reflecting the trust placed in the agent.

The core of agency law involves understanding the authority granted to the agent and the limitations of that authority. It also addresses the consequences arising when an agent acts within or outside their authority. Thus, the emphasis on the act of authorizing another to represent or act on one's behalf is what makes this aspect of law central to agency law.

In contrast, the other choices focus on different legal concepts. Legal representation by an attorney pertains to the attorney-client relationship, enforcement of contracts relates to contract law principles, and ownership rights deal with property law. Each of these areas is distinct and does not capture the essence of agency law as effectively as the correct answer does.
