Answer:
Fred will win because the right to receive payment could be validly assigned.
Step-by-step explanation:
all contract gives room for some certain rights and duties. By an obligation, the individual whose right it is to receive payment will transfer the right to collect that same payment from the same person (obligor) to any other person (third person).
Going by the question above Belinda, the well-known portrait painter is the obligee who transfers the right to receive payments from the obligors to a third party named Fred who is stands as an assistant. It was clearly stated in the question that “Belinda also assigned to Fred the right to receive payment from Harry. Neither the contract Belinda had with Harry nor the contract she had with Michelle expressly prohibited assignment or delegation of contractual rights and duties.”
Going by this above statement then one can confirm it very clear that the payment could be assigned and receiving the payment is within Fred’s right.
