At the end of a divorce case, the judge signs a court order to make it final. The order will say who gets what property. It will also include decisions about the custody of any children involved, and whether one person will pay the other child support or maintenance.
Sometimes, a person needs to make a change to that order. For example, if they lost their job, they may need to change their child support. Or, if one person decides to move to another county or state, it could affect custody.
To change a divorce order, you need to file a motion. But keep in mind that there are limits to how a divorce order can be changed. For example, the judge has to base custody decisions on the best interests of the child.
You should file your motion as soon as possible. The sooner you do, the better your chance of success.
