What legal document grants someone the authority to make decisions on behalf of another person?

The correct answer is Power of Attorney, which is a legal document that authorizes one person to act on behalf of another person in legal and financial matters. This document is essential for situations where the principal (the person granting the authority) may be unable to make decisions due to health issues, absence, or other circumstances.

With a Power of Attorney, the designated representative, often called the agent or attorney-in-fact, can perform specific tasks such as managing financial transactions, signing documents, or making legal decisions in the best interest of the principal. This authority can be limited to specific actions or can be broad, granting extensive powers.

The other choices do not pertain to the same legal context. A Power of Compliance typically relates to adherence to rules or standards rather than granting decision-making authority. A Lease Agreement is a contract between a landlord and tenant regarding the rental of property and does not confer decision-making power over another person. A Delegation Notice, while it may imply the transfer of certain tasks, is not a recognized legal instrument that grants authority like the Power of Attorney does.
