What's the biggest mistake people often make when dealing with an insurance claim?

Biggest mistake people make when dealing with insurance claim is not documenting damage thoroughly, failing to understand policy, and accepting first low offer too quickly without proper evidence. Many claimants do not take photos and videos immediately after damage, do not keep receipts and inventory of belongings, and do not get independent repair estimates, making it hard to prove loss, similar to not organizing tools in Packout boxes and losing track. Other big mistakes include admitting fault or giving recorded statement without understanding coverage, not reporting claim promptly which can lead to denial, throwing away damaged items before adjuster inspects, and not reading policy to know what is covered and what exclusions exist like flood. People also make mistake of not keeping communication in writing and not following up, allowing claim to stall. Accepting first settlement offer which is often lowball without negotiating or consulting public adjuster or attorney for large claims is common mistake. Also failing to mitigate further damage, like not covering broken roof leading to more water damage, can reduce payout as policy requires mitigation. To avoid biggest mistake, document everything with photos, keep receipts, read policy, get independent estimates, communicate in writing, do not rush to accept first offer, and consider professional help for large claims to ensure fair settlement.
