A Power Of Attorney (POA) or letter of attorney is a written authorization to represent or act on another’s behalf in private affairs, business, or some other legal matter, sometimes against the wishes of the other. The person authorizing the other to act is the principal, grantor, or donor (of the power). A Power of Attorney is not an instrument of transfer in regard to any right, title or interest in an immovable property. A Power Of Attorney, or letter of attorney, is a document that authorizes another person, known as the agent or attorney-in-facts€” usually a legally competent relative or close friend over 18 years old-to handle any combination of financial, legal and health care decisions. A power of attorney is also referred to as a POA. Generally, one chooses a POA as a provision if he or she becomes incapacitated.
