Car Car finance

I just need to know. My late wife bord a care in 2019. Now I found out there was no credit life insurance or any insurance on the car besides comprehensive insurance. Can a bank sell a car worth that amount without any assurance. What if the car was a total loss. And further more when investigating these things I found that paperwork was filled in and we were not married in community of property. When the car was purchased I was present and my late wife definitely did not state that we we out of community of property. Is there anything I can do?
