A durable power of attorney is a role recognized by Arizona government and by other states in the nation. It’s a special form of authorization that allows a person to make decisions and act on behalf of someone else, even if the principal becomes ill or unable to communicate. Not everyone needs a durable power of attorney, and it’s essential to choose someone you trust when appointing someone to this role. In trust and estate law, a durable power of attorney has authority to make decisions on your behalf, manage your finances and real estate, and handle your personal healthcare matters in accordance with your stated wishes.
