In California, judgments are issued in family law cases. Judgments typically terminate most aspects of the case. However, modifications can be sought, particularly for matters related to custody or enforcement. It is completely within your rights to seek a modification. If one party petitions to modify a judgment, it can indeed be challenged or opposed by the other party. The process follows procedures similar to those used during the initial hearing.nnBoth parties have the opportunity to present their arguments, and the judge may encourage them to try to reach an agreement outside of court. If necessary, additional evidence may be presented, and an evidentiary hearing may be held, similar to a trial on the specific issue in question. Know that modifying a judgment may be particularly challenging, especially if both parties initially agreed to the terms or if there are no substantial changes in circumstances.
