Book III: Different ways of acquiring property

The mandatary is bound to perform the mandate for as long as he remains in charge of it, and is liable for any damages that may result from his non-performance. He is likewise bound to complete the thing begun on the death of the principal, if there is peril in the house.

The mandatary is liable not only for fraud, but also for the faults he commits in his management. Nevertheless, liability for faults is applied less rigorously to one whose mandate is gratuitous than to one who receives a salary.

Every agent is bound to render an account of his management, and to account to the principal for all that he has received by virtue of his power of attorney, even if what he would have received had not been due to the principal.

The mandatary is liable for the person he has substituted in the management: 1° when he has not received the power to substitute anyone; 2° when this power has been conferred on him without the designation of a person, and the person he has chosen was notoriously incapable or insolvent. In all cases, the principal may act directly against the person whom the agent has substituted.

When there are several proxies or agents established by the same deed, there is solidarity between them only insofar as it is expressed.

The agent shall owe interest on the sums which he has employed for his use from the date of such employment; and on those of which he is in arrears from the day on which he is put in default.

An agent who has given the party with whom he contracts in that capacity sufficient knowledge of his powers is not bound by any guarantee for what has been done beyond that, if he has not personally submitted to it.
