(1) If the sum insured considerably exceeds the value of the insured interest (insurable value), each contracting party may request that the sum insured be reduced with immediate effect in order to eliminate the overinsurance, thereby also reducing the premium proportionally.
(2) If the policyholder concludes the contract with the intention of gaining an illegal pecuniary benefit on account of the overinsurance, the contract is void; the insurer is entitled to the premium up until such time as he or she learned of the circumstances establishing nullity.
