Auto insurance is a policy generated in the system, and the chapters on the policy he uses to print are all printed in advance.
This does not affect your claim.
After the auto insurance is generated in the system, as long as the insurance policy is issued, the auto insurance will be entered into the system and will not be changed.
This is legally binding.
If the insurance company refuses to pay, it will definitely use other reasons.
You won't refuse to pay the claim just because you haven't signed it.
But you'd better check whether your license plate number and engine number are correct, and what insurance is on it, and it's OK.
