2542. Where the insured has over-insured under an unvalued contract, a proportionate part of the premium is returnable.
The same applies in the case of over-insurance resulting from several contracts, if effected without the knowledge of the insured. But if the contracts have become effective at different times, and any of the contracts has, at any time, borne the entire risk or if an indemnity has been paid by the insurer in respect of the full sum insured thereby, no premium is returnable in respect of that contract.
