Any person who is insured with several insurers under several policies, for the same interest, against the same risk, must immediately inform each insurer of the other insurers.
At the time of such notification, the insured must indicate the name of the insurer with whom another insurance policy has been taken out and the sum insured.
Where several insurances against the same risk are taken out fraudulently or deceitfully, the penalties provided for in the first paragraph of article L. 121-3 shall apply.
When they are taken out without fraud, each of them produces its effects within the limits of the cover provided by the contract and in compliance with the provisions of article L. 121-1, regardless of the date on which the insurance was taken out. Within these limits, the beneficiary of the contract may obtain compensation for his losses from the insurer of his choice.
In relations between insurers, the contribution of each of them is determined by applying to the amount of the loss the ratio existing between the indemnity which it would have paid if it had been alone and the cumulative amount of the indemnities which would have been payable by each insurer if it had been alone.
