Looking for some advice. My partner has a very toxic relationship with his ex, going on 8 years! There has been lots of parental alienation to the point that the eldest now has severe emotional problems and refuses contact. The relationship with the youngest is fine. Contact had been chipped away by mum so we went to court to firm up arrangements, which solidified an over night stay once a week and every other weekend. 3 days after the court order was granted, ex has informed us her and the children are moving 4 hours away. She promised better contact and said she would try to improve her behaviour and the co-parenting relationship, but has straight away become difficult and controlling again, booking holidays over his weekends etc. How strong would a prohibited step order be in our case? If she's being obstructive 30mins away, we fear the increased distance is only going to make things worse, and potentially damage the relationship with youngest, and no hopes of reconciliation with the eldest.
