Verbatim from the Royal Gazette / Office of the Council of State
English translation
A declaration of intention is voidable if made under a mistake as to a quality of the person. Mistake under paragraph one must be a mistake as to the quality of the person which is considered as essential in the ordinary dealings, and without which such juristic act would have not been made.
