People often mix up a power of attorney with an executor, but they do different jobs at different times. A power of attorney lets one living person give another person legal authority to act on their behalf while they are still alive. An executor gets authority from a will and handles the person's estate only after death. That difference matters: a power of attorney usually ends when the person dies, and from that point on, the executor or a court-appointed personal representative takes over.

A power of attorney can be broad or limited. It may cover banking, bills, real estate, insurance, taxes, or other financial decisions. A durable power of attorney stays effective even if the person later becomes incapacitated. A separate medical document may be needed for health care choices, depending on how the paperwork is written.

This document can help keep life moving when someone is injured, hospitalized, or stranded by a sudden emergency. But it also creates an opening for abuse. The person named as agent has serious control over money and property, so the wrong choice can drain accounts, transfer assets, or pressure a vulnerable adult.

In Mississippi, the Mississippi Uniform Power of Attorney Act (2016), Miss. Code Ann. § 87-3-101 and following, sets out default rules for creation, agent duties, and acceptance. In an injury claim, an agent may be able to gather records, pay bills, or hire a lawyer - but cannot rewrite a will unless the law and document clearly allow it.
