Living Will
A legal document that sets out the medical care an individual, or the principal, wants or does not want in the event that they become incapable of doing it themselves.
Investopedia Commentary
A living will is used by people whose wishes will be met should they reach a point when they are no longer able to make the decisions for themselves. For example, if a person obtained life-threatening injuries, or was incapacitated as a result of some terminal illness, the decisions about their health care will be theirs as long as they have a living will. Without one the decision becomes the responsibility of spouses, family members or other third parties.
