(1) If the assumption of the debt is agreed between the third party and the obligor, its effectiveness is subject to ratification by the obligee. Ratification may only occur when the obligor or the third party has informed the obligee of the assumption of the debt. Until ratification, the parties may alter or cancel the contract.
(2) If ratification is refused, assumption of the debt is deemed not to have occurred. If the obligor or the third party demands, specifying a period of time, that the obligee make a declaration relating to the ratification, the ratification may only be declared before the end of the period of time; if it is not declared it is deemed to be refused.
(3) As long as the obligee has not granted ratification, then in case of doubt the transferee is obliged to the obligor to satisfy the obligee in good time. The same applies if the obligee refuses ratification.
