Reverse insurance
The retroactive insurance is an exception to the principle that insurance coverage is granted only for the future (principle of forward insurance). The reverse insurance is thus settled with the question of the start of insurance of an insurance contract . With reverse insurance, the technical and material start of a contract are placed before the formal start. This means that the period charged with the premium and the time at which the insurer bears the risk is before the time at which the contract is concluded.
If the insurer knows when concluding the contract that the possibility of an insured event is excluded, then he has no premium claim. If the policyholder knows in return that the damage has already occurred, he has no claim to benefits.
The reverse insurance is regulated in § 2 VVG Germany .
The concept of backward insurance is to be distinguished from that of backdating and that of reinsurance .
