Bills of exchange subscribed by minors are void as regards them, save for the respective rights of the parties, in accordance with Article 1352-4 of the Civil Code.
If the bill of exchange bears signatures of persons incapable of obligating themselves by bill of exchange, false signatures or signatures of imaginary persons or signatures which, for any other reason, cannot bind the persons who signed the bill of exchange, or in whose name it was signed, the obligations of the other signatories are no less valid.
Whoever signs a bill of exchange as the representative of a person for whom he had no authority to act, is himself obliged under the bill and, if he has paid, has the same rights as the purported principal would have had. The same applies to a representative who has exceeded his powers.
