My partner is in the defence force and we have lived separately for over two years because of custody of children arrangements in place with my ex. He has just been offered a promotion which means more money but also means another 2 years interstate. We will be together for 7 years in a couple of months and desperately want to have children together but because he is interstate we put it off. We have decided that it's now best that we are back together because it was only supposed to be until the end of this year, but it would be silly to say no to a promotion that in the long run will help us better support our family. So I want to take my children to Sydney from Melbourne. Currently they see their biological dad every second weekend and half of holidays. I have offered him once a month (long weekends where possible) and all of term school holidays and 4 weeks at Christmas holidays which would give him an extra 20 nights per year. My 9-year-old wants to come, and he sees that his dad and dad's gf are trying to manipulate him and calling me a liar, etc. My 8-year-old, who has a mild disability ( autism spectrum) is falling for their promises of dirt bike riding, etc and keeps wavering back and forth. When he is with me he says he wants to go to Sydney but when he is with them he says he wants to stay. They do not acknowledge the autism and have never participated in any therapies or any school events at all for that matter. I just want some idea of my chances of family court granting me a relocation order if it gets that far? I would prefer not to take it to family court, but I need my family back together. I should note that he did allow me to move with them when they were 2 & 3, but we managed to get a posting back to Melbourne before they started school. I've always tried to keep the peace but this is really important to the health of my family, I've sacrificed a lot for my boys to have a meaningful relationship with their dad, and that would still happen from Sydney-But surely my happiness counts for something?
