Article 149a of the Swiss Law on Debt Collection and Bankruptcy (SchKG) provides that claims based on a loss certificate become time-barred within 20 years after the date of its issuance. According to the transitional provisions, this time limit applies equally to loss certificates issued prior to the enactment of article 149a which came into force on 1 January 1997.1 Prior to that change in the law, claims based on loss certificates were not subject to prescription.
