Is it legal for a person with power of attorney to revoke that person's living will?

A person with power of attorney generally does not have the authority to revoke a living will unless specifically granted that power within the document or by the principal. A living will is a legal document outlining a person's wishes regarding medical treatment, and only the individual who created it can typically modify or revoke it. If the principal is incapacitated, the power of attorney may have to follow the directives outlined in the living will. It is important to consult legal counsel for specific situations, as laws can vary by jurisdiction.
