I have a joint residency order with my ex, our daughter lives with her mum from monday to friday and with us from friday to monday.
My eldest (12) said that she wanted to change her living arrangements around so that she was with our household monday to friday and at her mothers friday to monday.
Her mother has always agreed that the choice was hers to make, she wouldn't try and stop her etc. Of course that only applied until my daughter actually made the choice then all hell broke loose. Her mother refused point blank to allow it, wouldn't even consider it. After a couple of weeks she allowed contact after school one day a week and her boyfriend would pick her up on his way home from work. Which was fine until his working day got so short that we would only be home from school for an hour and a half before he would show up to take her to her mums. It wasn't working.
Mother still refused to let the requested change happen, so off to court we went. All the fun of background checks and CAFCASS interviews and several hearings in court later and we have a variation to the existing order where my daughter is the one in charge of where she stays and when!
My ex went full retard then, threatening to harm herself if my daughter didn't give up the court case, took her laptop away and threatened to sell it to pay some solicitors fees, etc, proper evil cow stuff.
Had a decent bundle of paperwork to dump on the ex in court, abusive messages, threats against my wife, the rag like school jumpers she would send my daughter to school in, stacks of it. And the judge didn't want to see any of it, he went straight to the fact that he could make any order he wanted and if a 12 year old girl decides to ignore it there isn't a damn thing anybody can do about it!
Been 7 months from start to finish (eldest was hoping to be home before the baby was born but her mother dragged it out as long as she could for "reasons"*) but yesterday it was all finished. My ex now has to let my daughter have what she's always told her she could have.
Finally got all my babies under one roof
Sooooo Happy. 
* my ex hasn't lifted a finger in 26 years, she wanted to hold on to her ticket as long as possible.
