CC 3146 - Implied consent of owner.
Art. 3146. Implied consent of owner.
But this tacit consent must be inferred from circumstances, so strong as to have [leave] no doubt of the owner's intention; as if he was present at the making of the contract,* or if he himself delivered to the creditor the thing pawned.
*Note error in English translation of French text; "present at the making of the contract" should be "a witness to the act of pledge."
