When should I contact a lawyer to recieve back childsupport because my Ex will be recieving a Inheritence?

There is a New Jersey law that requires the Executor of an estate to do a child support judgment search, and if they fail to pay the back judgment, the Executor becomes responsible.  You should get a copy of the probated will from the county in which the person died.  The Probate clerk will be able to either provide you with a copy of everything in the file, or direct you as to how to get that.  Look on the documents and see if ther eis an attorney that assisted with the probate, and if there is, send notice to that attorney now.  Send a Certified letter with the green card receipt, and keep that receipt.  Make sure that the amount of your outstanding child support has been confirmed either through probation, or by a judgment.  You do not need ot hire a lawyer to get this money for you, it is a New Jersey law that the executor has to pay it to you.
