Hi. I have been separated for 3 years from my de facto ( separation). Our kids are 8 and nearly 5. Our 8 year old has been going to school in the same place for 2.5 yrs. Both kids know the teachers, school rules, etc but my ex has now bought a house (but he's not paying child support) and wants to enrol both kids in the school he lives near (300m away). This makes it 12km away from me. He will not budge on wanting to move them and I would prefer the stability of having them in the same school they have known for so long. At this stage, it's the only thing that's stable in their lives :-( As school has only one week to go, what are my legal rights? He took me to mediation, but he said he will not change he his mind. Thank you.
