2511. It is not necessary that the insurable interest exist when the contract is made but it is necessary that it exist at the time of the loss.
The acquisition of an interest after a loss does not validate the insurance. However, where the property is insured lost or not lost, the insurance is valid although the insured may not have acquired his interest until after the loss provided that, at the time of making the contract, the insured was not aware of the loss.
