A power-of-attorney document includes the name of the individual designating the power, the details of the allowed power, such as financial or medical decisions, and the individual's signature and date, the Minnesota Judicial Branch explains. A power-of-attorney must have notarization.
A power-of-attorney form provides one person, called the agent, to act on the behalf of another person, called the principal, the Free Dictionary reports. A power-of-attorney may be necessary for someone who is unable to handle financial matters on his own, or it can give the agent the power to sign for the purchase or sale of real estate, notes the American Bar Association. The power-of-attorney can provide the agent temporary or permanent authority.
The exact requirements and abilities of a power-of-attorney can vary by state law, according to the American Bar Association. All 50 states accept power-of-attorney contracts, but some states require documentation that proves the person has power-of-attorney. All states have laws that state a power-of-attorney expires upon the death of the principal. When the agent learns of the principal's death, he may no longer act as the principal's agent. However, the agent can act on the principal's behalf if he has not yet learned of the principal's death, explains Legal Zoom.
