No, a person with power of attorney does not typically override a will. The power of attorney is a legal document that grants someone (the agent or attorney-in-fact) the authority to make decisions and act on behalf of another person (the principal) in financial, legal, or other matters. The power of attorney ceases to have effect upon the death of the principal.

On the other hand, a will is a legal document that outlines how a person’s assets and estate should be distributed after their death. The instructions in a will generally take precedence over the decisions made by someone with power of attorney. After a person passes away, the will is typically submitted to probate, a legal process in which the court validates the will and ensures its proper administration.
