If you are filing a diminished value claim, you should file it as soon as possible. If you don’t file your claim within the right time frame, then you may lose your right to compensation.
It is important to note that if an auto insurance company rejects your claim or denies coverage, there is no statute of limitations on how long they have to pay out on the claim. What this means is that even if they reject or deny your claims today, they can still be required by law to pay out on those claims later down the road (depending on different state laws).
