Answer:
The insured must submit written proof of the loss suffered (the reason of filing the claim).
Explanation:
Usually insurance companies have 30 calendar days to respond to a claim, (although that time may vary on some states).
Therefore if you have't received a response from them after one month, you should provide written proof that supports your claim, since the only excuse that the insurance company could give you, is that their investigation about the incident resulting in the claim is not over.
