Hi Team, I am looking to vary a parenting order before the first two years are up and I first need to seek leave of the court for this to happen (the other side are opposing)

Im looking for anyone who may know how to meet the threshold for overturning section 139(a) COCA, the section requires you to prove there has been a material change to circumstances of- any party/Child to the previous proceedings.

Any one with some case law that gives me some thing to reference when a judge actually approves the courts leave

Cheers
