Thanks for your reply.
As residency and contact have changed since the shared care agreement was entered into, does this mean it is unenforceable unless I go to court where a sheriff would have regard to the agreement and any new circumstances?
Could you also confirm if a shared care agreement can only be altered by a court order (the shared care agreement I entered into with ex was done my mutual agreement and not by a court order). The agreement was registered in the Books of Council and Session. There is an article on GOV.UK website that states a shared care agreement registered in BCS is a legally binding agreement and can only be varied by a court order. I was given this information by the Citizens Advice Bureau.
