Definition : Notice of loss

Written or oral statement that an insured sends to his insurer, claims adjuster or insurance broker serving as an intermediary, in relation to a loss likely to involve one of the guarantees of the insurance contract. It must be made by the insured, as soon as he becomes aware of the claim, or by any interested party. 

WARNING ! An insurer who has not been so notified, and thereby suffers injury, in such a case, may set up against the insured any clause of the policy providing for forfeiture of the right to indemnity in such a case.
