How do you get a variation on a court order if you are non custodial parent?

To seek a variation on a court order as a non-custodial parent, you typically need to file a petition with the court that issued the original order. This petition should outline the reasons for the requested change, such as changes in circumstances or the welfare of the child. It may also require supporting documents and possibly a hearing where both parents can present their cases. It's advisable to consult a family law attorney to navigate the process effectively.
