Change an Existing Montana Family Court Order

FamilyCourtHelp is an independent educational platform. It is not a court, law firm, government agency, or government partner. 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 Montana family court order is not permanent, but changing one is its own filing in the District 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 Montana publishes for this.

Frequently asked questions

Do I start a new case to change my order?

Usually not. A modification is normally filed inside the existing case, and the other parent has to be served with it. Check the official Montana instructions above for how this state handles it.

What counts as enough of a change?

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.

How much does it cost to file a family case in Montana?

Dissolution filing fee: ~$170. If you cannot afford the fee, ask the clerk about a fee waiver or indigency application; every state has a process for requesting one.
