If, prior to completion of the programme, the project owner assigns the rights it has in the programme, the assignee is substituted ipso jure, actively and passively, for it in the entire contract. The assignor is guarantor of the performance of the obligations placed on the project owner by the assigned contract.
Special mandates given to the developer continue between the developer and the assignee.
The developer may not substitute a third party for himself in the performance of the obligations he has entered into towards the project owner without the latter’s agreement.
The property development contract may only be relied on as against third parties from the date on which it is entered in the property register.
