A durable power of attorney is an agent appointed by you that can handle your financial accounts and property in the event that you become incapacitated. This means that he can continue to make payments to utility companies, pay credit card bills and manage bank accounts on your behalf. Without this special power of attorney, a court will have to appoint a guardian, which takes time. Make sure that your agent for this agreement is a person you trust, as he will have full control over your financial life.
