1663. Where novation is effected by substitution of a new debtor, the new debtor may not set up against the creditor the defenses which he could have raised against the former debtor, nor the defenses which the former debtor had against the creditor, unless, in the latter case, he may invoke the nullity of the act that bound them.
Furthermore, hypothecs attached to the former claim may not be transferred to the property of the new debtor; nor may they be reserved upon the property of the former debtor without his consent. However, they may be transferred to property acquired from the former debtor by the new debtor, if the new debtor consents thereto.
