Legal Question in Family Law in Nevada

Well, it depends. If he has anything to get (if he's a hobo living in a cardboard box there is not much to do, really), the usual course is to either sign up through the D.A., wait, and hope for the best, or hire private counsel to file a motion to reduce arrears to judgment, plus interest, penalties, and fees. I suggest starting with a bit of reading, for example, http://willicklawgroup.com/interest-penalties/, plus the child support and some other pages on that same site, and then call to ask specific questions, go over the facts, and consider setting up a consultation or hiring counsel for collections.
