My son recently bought a house whose owner recently died of Covid. The owner left a van which currently sitting on my sons garage. Technically my son owns it as it was left in his property. How can we register the car?

Although, it was left on the property he needs the title signed over to his name. The other choice us the power of attorney. Try and see if you can find one of his family members will turn it over fo him. By the way whatever happens make sure it's thoroughly disinfected. Best

You would have to contact the dmv directly, this is a Google maps community review and information forum.
