Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Which part of the Uk is she in and how old is the child?
is the father named on the birth certificate?
Has he given a reason for what he is doing?
Is he actually cpable of caring form him overnight or is this designed simply to scare her?
In that case your friend needs to complete the form C100 here
and the EX160
https://www.stepchange.org/Portals/0/Clients/EX160_form.pdfasking for an Order that the child is returned to her care and that her ex cannot remove the child from her care
and take it to the court as soon as posisble - before 4 - and ask for an urgent immediate hearing.
Once she has the order she can ask the Police to help her recover the child
Please ask if you need further details
