AIS Answer: People often do cash the insurance claim check and keep the money and as long as the check is written out to you, you can cash it. Whether you can keep it is up to the agreement you may have signed with the insurance company.
If your vehicle is damaged and needs repairs (isn’t written off as a loss) the insurance company in good faith has written you a check to cover the repair of the vehicle and it’s a smart idea to use the money to fix the damage.
In some instances an insurance company will write you a check for the total payoff (actual cash value) of your vehicle in the case of a totaled automobile. This is of course a check you personally cash and can choose to put it towards a new vehicle or keep the money for something else.
