Plain-English meaning

Living Will

An advance health-care document stating treatment preferences for specified incapacity or end-of-life circumstances.

Why the term matters

It gives clinicians and decision-makers evidence of the person's choices when direct communication is not possible.

Do not confuse it with

A living will concerns medical treatment; a last will and testament addresses property and probate after death.

Where you may see it

The term may appear in a signed will or trust, a court petition or order, a deed, an account or policy form, a fiduciary report, or correspondence from a tax or benefit agency. Read the defined-terms section and the complete sentence before deciding what role or action it describes.

Records that give the term context

  • the current living will and health-care agent document
  • notes of discussions with the agent and clinicians
  • the signed original will and every codicil
  • a list of assets showing title and beneficiary designations

What to verify

  • Which medical conditions trigger the instructions?
  • Who resolves uncertainty between written instructions and an agent?
  • Which assets would actually be controlled by the will?
  • What execution rules apply in the signing state?

Example without case advice

If a notice uses “living will,” first identify the person or property the word refers to, the document supplying the definition, and the deadline or decision attached to it. The same word can carry a different procedural effect in a trust, probate file, tax form, or account contract.

Sources to verify

Use the controlling court, agency, statute, provider record, or governing document before relying on a general explanation.
