My husband has had consent orders finalised through family the court since 2013. The orders are a standard alternate weekend, half school holidays. His daughter has just started high school and the holidays in June and December are now 3 and 7 weeks respectively. Therefore, the weekends alter after June and December rather than follow alternate as they have due her being at the primary school that had even holidays. His ex-wife is referring to the 'alternate' definition, therefore, whoever has the child on the last weekend before the school holidays, the alternate parent has the child on return to school (orders are null and void on holidays). Due to my husband's work commitments, he needs the weekends to remain as they are and have asked if he was to forgo a weekend to bring it in line. She refuses and refers to the orders. She doesn't work and hasn't since 2013 What can we do to get the weekends back on track ?
