How is a living will or health care power of attorney revoked?
By destroying the documents, by your agents, health care providers and family not to honor them, or by doing new ones. Make sure that all copies of a revoked (or amended) document are retrieved and replaced with copies of a new (or amended) document. We recommend keeping a copy of revoked directives, provided they are clearly marked “revoked.” This provides a history of your attention to this subject.
