Car in Ex's name - can he take it?

I was legally divorced in 2/2011. We never had an equitable distribution hearing. My ex lost his job around the time the divorce was legal. The car I drive is still in his name. It is a Toyota Highlander 2008 - with no payments. This was my car during the marriage, separation, and has been in my possession since the divorce. He kept stalling on putting it in his name. Now he wants to sell the car and get half of the proceeds. Can he take my car? He left the marriage without having to pay alimony or anything. I would at least like to keep my car. Thank You
