1555. Payment may be made by any person, even if he is a third person with respect to the obligation; the creditor may be put in default by the offer of a third person to perform the obligation in the name of the debtor, provided the offer is made for the benefit of the debtor and not merely to change creditors.
A creditor may not be compelled to take payment from a third person, however, if he has an interest in having the obligation performed by the debtor personally.
