Where the transfer relates solely to bare ownership or usufruct, deeds and declarations relating to gratuitous transfers must disclose the date and place of birth of the usufructuary; and, if the birth occurred outside France, this date must, in addition, be proven before registration.
Failing this, the highest duties that may be due to the Treasury shall be levied, except, as stated in article 1965 C, restitution of the overpayment on the representation of the birth certificate, in the event that the birth took place outside France.
