My ex has previously been having dcs at weekends.
He has now changed to being self employed and wants to decide access on a week-by-week basis depending on which days are most suitable for him.
This is unworkable for me, in that the dcs need stability and routine (after a horrible year of him being very unreliable and hardly seeing them). They also need to have their extra curricular classes arranged, which he refuses to help out out with and I think (in fact am sure) he would not take them. I would have to give him my important dates in advance (appointments etc) in the hope that he would take this into consideration and could not plan certain things in advance.
I would also have to deal with him to make the arrangements and can imagine the resulting rows when I disagreed with the offered dates.
AIBU to say that he must now go and arrange access formally? I think this ad hoc arrangement would not be approved in court?
