An expression of intent which an agent makes in the name of the principal within the scope of his delegated power takes effect directly to the principal.
If an expression of intent which is required to be made to the principal is made to his agent, the provision of the preceding paragraph shall be mutatis mutandis applied.

The effectiveness of an expression of intent made by or to an agent is not impaired by the fact that he is limited in the capacity to make juridical acts.

If the effectiveness of an expression of intent of an agent is impaired by the lack of intent, by fraud, or by duress, or by knowledge, or by culpable ignorance of certain circumstances, the existence of the fact shall be determined with regard to the agent.
But if the agent derives his authority from a juridical act and the expression of intent was made following the definite instructions of the principal, the existence of the fact shall be determined with regard to the principal.

Without the consent of the principal, an agent shall not make a juridical act in the name of his principal with himself in his own name, nor shall he, as an agent of a third party, make a juridical act in the name of the principal with such third party, except when the juridical act consists exclusively in the performance of an obligation.

The limitation or withdrawal of the delegated power shall not be a valid defense against any bona fide third party, except the ignorance of the third party is due to his fault.

The delegated power is terminated in accordance with the legal relation from which it is delegated.
The delegated power may be withdrawn for the duration of the legal relation from which it is delegated, except when according to the nature of the legal relation it can not be withdrawn.

At the termination or withdrawal of the delegated power, the agent shall return the written delegation of agency to the party who gave it; he has no right to retain it.

If one who has no delegated power to make a juridical act as an agent of another person, he is liable for the injury to the bona fide other party.
