Article 1984

The depositary cannot demand that the depositor prove his ownership of the thing deposited.

Nevertheless, should he discover that the thing has been stolen and who its true owner is, he must advise the latter of the deposit.

If the owner, in spite of such information, does not claim it within the period of one month, the depositary shall be relieved of all responsibility by returning the thing deposited to the depositor.

If the depositary has reasonable grounds to believe that the thing has not been lawfully acquired by the depositor, the former may return the same. (1771a)
