A durable power of attorney is a legal document that allows you to appoint an agent to represent you in your financial matters in case you are incapacitated. You could also make the decision to appoint an agent now if you are needing the help or assistance because of age, health or disability. You can place limits on the Power of Attorney. This is a way to protect yourself to make sure your bills, expenses and necessities are provided for and taken care of by someone you trust.
