We organize and link to publicly available resources published by courts and government agencies. Official requirements may change. Always confirm current requirements with the applicable court or clerk.
A Massachusetts family court order is not permanent, but changing one is its own filing in the Probate and Family Court, normally inside the case that produced the original order.
Courts generally want to see that something real has changed since the last order, not simply that you have changed your mind. For support, an updated financial affidavit almost always rides along with the request. The official documents below are what Massachusetts publishes for this.

Usually not. A modification is normally filed inside the existing case, and the other parent has to be served with it. Check the official Massachusetts instructions above for how this state handles it.
Courts look for a real, lasting change in circumstances, such as a significant income change, a move, or a serious change in the child's needs. The judge decides whether your facts clear the bar.
