A living will, or directive to physicians, is a document that allows you to instruct your physicians not to use artificial methods to extend your life in the event you are diagnosed with a terminal or irreversible condition.
A question I often get asked is whether an advice directive signed in another state is considered valid in Texas. It is.
The Texas Health and Safety Code specifies that an advance directive or similar instrument validly executed in another state or jurisdiction will be given the same effect as an advance directive validly executed under the law of Texas. However, the statute does not authorize the administration, withholding, or withdrawal of health care otherwise prohibited by the laws of Texas.
