There was no residence order in place previously, it was a shared parenting schedule.
The former matrimonial home was sold (previously I was living in shared accommodation), so that freed up funds so I could get my own place. My daughter started staying for extended overnights and was requesting to stay longer, my ex was fine with this. eventually it was a week on a week off and my daughter was fine with that. the ex tried to unilaterally change the schedule by bullying me verbally, intimidating me, threatening to call the police. She refused to attend family mediation when I suggested it to discuss matters, even though I made all the appointments and attended my 1st appointment.
When her further bullying and threats didn't work, she applied for a sole residence order, depsite our daughter having a basically 50:50 shared care arrangement in place for 6 months.
When I first went to court, due to the inept actions of my solicitor/tapeworm (who was subsequently sacked) and a worse than useless biased judge, plus a biased duty CAFCASS officer, my daughters contact time with dad was reduced by 50%.
After it's all been sorted now, it works out that DD lives at mine for approx. 35% time per year, she wants to stay more but the only way to vary the time would be to take it back to court, something which would be financially and emotionally draining.
My ex is more than happy for DD to stay at mine more when it suits her - i.e. her social life, sometimes it seems that DD is more of a hinderance to her. Hopefully as DD grows up more and is able to voice her opinion more she will be able to make her decisions on her own steam...
