We can not give you advice on it you should or should not sign the letter of consent but hope to explain why the insurance company is likely sending this to you. One reason that AAA auto insurance sent this is to verify that the driver of your car had permission to drive the vehicle at the time of the incident. If the driver did not have permission most insurance companies would not cover the claim.

The other reason for the form might be to find out if you gave permission to the son and also find out if he lives at your residence. If he does and you did not disclose him as a household member with a driver's license that needed to be added to your policy there could be consequences.

Speak with your car insurance agent at AAA to find out more specifics about the form. If you need more help you can get legal advice or contact your state's insurance regulator.
