A power of attorney is one of the most important legal documents a senior can have in place before a health crisis occurs. It designates a trusted person — the “agent” or “attorney-in-fact” — to act on the senior’s behalf in financial, legal, or medical matters.

Texas recognizes two main types: a Durable Power of Attorney for finances and property, and a Medical Power of Attorney (also called a healthcare proxy) for healthcare decisions. “Durable” means the document remains valid even if the principal becomes mentally incapacitated — critical for elder care situations.

A POA can only be executed by someone who is legally competent at the time of signing. Once a person loses decision-making capacity without a POA in place, the only legal recourse is often a court-ordered guardianship — a more expensive, slower, and less private process.

In Texas, a Durable Power of Attorney must be signed before a notary public. A Medical Power of Attorney requires two disinterested witnesses. Family members acting under POA are legally obligated to act in the principal’s best interests — not their own.
