Easy. Just petition court for exactly that. A change of venue...its determined by where the child lives.
It's not necessarily automatic. You should show the custody order to the venue that issued the child support order.
If court will not accept a filing, request a change of venue. see link below
Request a change of venue, but you need a reason.
File a motion for change of venue. Why do you need it?
Change of Venue
No. You can appeal the court's decision but any custody case will usually be managed in the court of jurisdiction. You need to consult with an attorney in your area, one who specializes in custody and family law. You can file a petition for custody and/or a visitation schedule. Unless there is a question of fitness of the parent, courts seek to encourage healthy relationships with the child and both parents. You could visit the court and ask to speak with an advocate if you cannot afford to consult with an attorney.
Generally, no. But, there are circumstances under which other states can and have taken jurisdiction. The most common way is through the use of an allegation of abuse, though the claim need not be true. The court will rule on the side of caution in taking jurisdiction. By the time an allegation is disproved, if it's not true, the new state has jurisdiction under the UCJAA, thus achieving the same results. see link
Child support payments change or stop only by order of the venue that issued the order for support.
You file for a termination of support in the court where the original order was issued or if there was a change of venue due to the move, in that court. If you are not in arrears or the custodial parent has not filed for and been awarded an extended support modification, your petition for termination will be granted.
Requesting a CHANGE OF VENUE.
A motion for change of venue in the state of New Jersey Superior Court needs to be filed through the Chancery Division. The motion must be filed within ten days of notice.
You or your attorney will need to file a request for a change of venue. In most cases, there needs to be very expllicit reasons for a change of venue. The most common reasons for change of venue are that the judge is related to one of the litigants (you or your ex) or the jury has been over exposed to the story in the news. You will not normally have a jury case, so you will need to show that the judge is unable to hear and decide the case. This is difficult to do. In addition, you risk making the judge less than friendly to your cause or your side if your point is that he or she is incapable of being unbiased in this case. It is a slight slur to the judge when you clearly state that he or she can't do his job.
