In the case of a vague transfer of debt, that is to say, in the case of a transfer of debt where it is not stipulated whether the subject matter of the transfer is payable forthwith, if the debt is likewise payable forthwith by the transferor. If the debt is payable at some future definite date, the transfer is of the same nature, and payment must be made when the debt falls due. That is to say, the transferee takes from the transferor exactly the same type of money that was the subject of the transfer. He cannot, however, claim the identical money which has been paid. Silver money is transferred.
Payment is made in gold.
Silver money may be claimed from the transferor and not gold. Payment is made with goods and effects. The money which was the subject of the transfer may be claimed. If the subject matter of the transfer is paid, or it is transferred to some other person, or the person in whose favour the transfer is made liberates the transferee from the debt, or the person in whose favour the transfer is made makes a gift of the subject matter of the transfer or disposes of it as alms and the transferee accepts, he is liberated from the debt. In the event of the death of the person in whose favour the transfer is made, and of the transferee becoming his heir, the transfer becomes devoid of effect.
