Claim in enrichment

A person who, under the provisions of sections 973, 974 and 976, suffers a loss of rights, may require, in the cases governed by sections 973 and 974 from the finder, in the cases governed by section 976 from the municipality of the location of the finding, the surrender of what has been obtained as a result of the change of rights, in accordance with the provisions on the surrender of unjust enrichment. The claim is extinguished on the expiry of three years after the ownership devolves to the finder or the municipality, unless it is judicially asserted prior to this.
