A power of attorney (POA) is a legal document in which the principal (you) designates another person (called the agent or attorney-in-fact) to act on your behalf. It becomes useful when a person is incapacitated or is absent for extended periods of time while working abroad, attending training in a different state, etc. The document authorizes the agent to make either a limited or broader set of decisions. Power of attorney can be limited in scope to a specific transaction, to an area of business, or it can be broad enough to encompass many aspects of principal’s life.
