WHEN YOU DIVORCE IS IT THE NEW JERSEY LAW THAT YOUR SPOUSE GETS HALF OF WHATEVER YOU HAVE WETHER THE SPOUSE HAS CONTRIBUTED OR IS NOT ON ANY DEEDS ?

There are a lot of special circumstances and no one answer fits all.  There should be equitable distribution, but what is equitable is not always half.  There needs to be some recognition of ownership of whatever property is the marital home, and the source of funds for other properties is relevant.  Were any of the assets inherited?  Any asset that is inherited, and does not become a joint asset is not subject to distribution
