A Maryland limited power of attorney form is used to select a representative to handle a sole financial decision or action. The activity can be anything monetary related and the agent is legally obligated to act in the principal’s best interests. The most common use for the document is to assign an agent to handle a real estate transaction. The form becomes null and void once the objective has been completed or as specified in the contract. Furthermore, the document does not have durability, meaning it does not remain valid if the principal should become incapacitated.
