Kuwait Court of Cassation principle number 967

An unjust enrichment action is time-barred upon the lapse of three years from the day on which the person who sustained damage learns of his right to compensation, or upon the expiry of fifteen years from the day on which that right arises, whichever period expires earlier. What matters for commencement of limitation is the actual knowledge of the person who sustained damage of his right. This is not established until the day the final judgment of nullity is rendered.
