Contract for sale lacks legal form; promise of sale must be in written document signed by both parties to be valid.

The court dismissed the request for review, ruling that a contract for the sale of real estate is void if not executed as a written document signed by both parties. The plaintiff argued for the contract's validity despite its informal execution, while the defendant maintained strict adherence to the Civil Code's formal requirements. The court held that without the mandatory written form, the agreement lacks legal effect and cannot be enforced.
