Kuwait Court of Cassation principle number 491

A challenge on grounds of absolute simulation. It must be explicit in its meaning that the apparent contract does not exist in reality. A challenge on grounds of collusion and fraud. It does not convey this. - A registered contract. Its priority over an unregistered contract. Proof of collusion between the parties to the latter contract to deprive the first purchaser does not alter this. The knowledge of the second purchaser who registered his sale contract does not constitute a presumption of simulation of the sale. Example.
