A durable power of attorney is a comprehensive document that allows an individual to relinquish control of their affairs to an appointed agent. There are various reasons as to why an individual might want to allow an agent to manage their personal affairs, and it is possible that over time these reasons might change and a person's situation may require that changes be made to the durable power of attorney.
Power of attorney laws are in place to aid and protect the individual granting the power of attorney, not the individual acting as the agent. There are situations that can arise which may affect a durable power of attorney, such as an agent moving from the area and no longer being able to effectively administer the affairs of the principal, or perhaps the current agent has not been acting in the best interests of the principal. Regardless of the reason, a durable power of attorney can be revoked or changed as long as the principal is still mentally competent to act.
