In insurances where the premium is deducted either on the basis of salaries or on the basis of the number of persons or things covered by the contract, it may be stipulated that, for any error or omission in the declarations used as a basis for fixing the premium, the insured must pay, in addition to the amount of the premium, compensation which may in no case exceed 50% of the omitted premium.
It may also be stipulated that where the errors or omissions are fraudulent by their nature, extent or repetition, the insurer is entitled to repeat the claims paid, independently of the payment of the indemnity provided for above.
