Comments and advice here can be helpful, but always check with your attorney.
Someone in this thread suggested to title your kid's car is their name only.
I am not an attorney, and I am not advising anyone. My insurance agents in this state and in another state (I live in 2 states and have assets in both states) told me that I can be held liable for any auto accident that my college age child has because I pay the college bills. Even though my 21 yo child paid cash for the car, titled it in their name only, and insured it in their name only, and the auto insurance bills are sent to my child's full-time apartment address and ins. bills are paid by my child. (it's totally absurd that I'm liable, but that's another thread)
So, if you have questions/concerns about asset protection consult an attorney or an appropriate professional. And, thanks everyone for the discussion as this topic is important to us all.
