CC 1849     

Art. 1849.  Proof of simulation

In all cases, testimonial or other evidence may be admitted to prove the existence or a presumption of a simulation or to rebut such a presumption. Nevertheless, between the parties, a counterletter is required to prove that an act purporting to transfer immovable property is an absolute simulation, except when a simulation is presumed or as necessary to protect the rights of forced heirs.
