This requires petitioning the Court for a modification of the Parenting Plan . There are minor modifications and major modifications. A minor modification is a small change such as a change in the dates of holiday visits. A major modification is a big change like a change in custody. The change does not get granted automatically. There is an initial hearing or threshold hearing where you must prove you have a good reason and adequate cause for the modification you are asking for. If you don’t meet the adequate cause threshold the judge will dismiss the case. If you get past the initial hearing the judge will schedule a trial date. For a major modification you will need to prove that there has been substantial change in the child’s or other parent’s life since the entry of the parenting plan and it is in the child’s best interests. For a minor modification you will need to prove that there has been a substantial change of circumstances in either parent’s life or the child’s life and the change is in the child’s best interests.
