I think it is clearly worded:
Dd cannot be removed from care of FinallyFree123456789, the care of anyone instructed by FinallyFree123456789 or from school or nursery except for orders of the court.
Expires April 2019
DD cannot be removed from care of FinallyFree123456789
or anyone FinallyFree123456789 has given care and responsibility for the child, ie nanny, childminder, grandparent etc
and cannot be removed from school or nursery, presumably without the express signed permission of FinallyFree123456789
and this order is in force until April 2019 - or until another order is granted before that date
It is quite clear that this order supercedes all previous orders and arrangements.
FinallyFree123456789 needs to get some photocopies of this order and email and personally hand deliver them to the to school, Headmaster/Headmistress, Head Teacher, the school office, The Legal people at the school and the Governors etc and the local police and get it signed for at the police station. Make sure the Police understand what it means, a policeman hovering at the school would be useful on the day
Schools like to not get involved and often don't understand the implications of a Court order, they tend to live in a bubble. Send a copy, through several ways, to the Father so he can't pretend he doesn't understand or know about it, including to his work etc or ask the Court to do this too. Nip this in the bud otherwise it will go on and on
Stopping him taking the child is a whole lot easier that trying to get the child back, this can takes weeks/ months. If there is any attempt by the Father to take the child from the school go back to Court and ask for Power of Arrest to be added it, you may not get this at the first attempt but the Judge will have Father in before him, will make sure he understands the order and will explain in no uncertain terms what happens if he tries this again.
Please take this seriously
