468. An application relating to acquisitive prescription of an immovable must be supported by a recent statement, certified by the registrar, setting out the rights registered in the land register. It must also be supported by a copy of or an extract from the cadastral plan or, if the immovable is not immatriculated or is a part of a lot, by a technical description of the immovable and the related plan, both prepared by a land surveyor. If a construction has been erected on the immovable, a location certificate must also be attached.
The court that is to determine the right of ownership may, even on its own initiative, order a determination of the boundaries of the immovable if the accuracy of the plan is contested by the owners of the adjoining immovables.
