The pledgee may stipulate the benefit of the pledge for themselves, provided that its duration is specified by time or by an act, and it is calculated as part of the debt, whether the debt arises from a sale or from a loan. If it is not calculated as part of the debt, stipulating such stipulation shall be prohibited where the debt arises from a loan, but shall be permissible where it arises from a deferred payment, provided that such condition is stipulated in the sale contract.
