A Missouri limited power of attorney form can be used to designate a representative to take care of your financial matters for a specific transaction or for a limited period of time. For instance, if there is a real estate transaction for which you are going to be away, you can appoint a person to sign on your behalf. There also may be an instance where you need someone to handle your finances for a short period of time while you are away on travel or deployed with the military.
