I have seen your question. My name is David Salvaggio.  I head a law firm that devotes its practice exclusively to New Jersey Family Law matters.  It's all we do. The safest thing for you to do-- if you cannot reach an agreement with your ex-- is to have a formal motion properly prepared, filed and served as soon as possible so that the court can decide the issue. A good Family lawyer will need more information, before being able to help you.   To obtain further guidance, I recommend that you meet as soon as possible with a very experienced lawyer who devotes his/her practice exclusively to New Jersey Family Law matters such as yours. Go over your situation in detail with the attorney, get educated answers to your questions, and obtain expert guidance as to the best course of action. In my opinion, it will be well worth the cost of the meeting. Your question does not specify the town in which you live.  My firm's offices are located in Morristown, NJ (Morris County).  We handle cases in all of the counties in northern and central New Jersey.  Please feel free to take a look at our Firm Website (www.salvaggiolaw.com), which contains a lot of helpful information.
