In matters of expropriation in the public interest, registration duties or land registration tax levied on amicable acquisitions made prior to the declaration of public interest are refunded when, within the time limits set by Article R196-1 of the Book of Tax Procedures, it is proven that the properties acquired are covered by this declaration of public interest or by the transferability order. The restitution of rights may only apply to the portion of the properties that has been recognised as necessary for the execution of the works.
