Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
How old are the chidlren and what is the current contact pattern?
When is the next Child Protection Conference?
Is the first one prior to his release?
Then that is when you make the decision.
By then you will have the necessary details AND have had the chance to hear whether or not she will indeed carry on with the relationship no matter what.
After that meeting you can prepare an application for a Child arrangement Order stating that the children live with you and spend time with her in the safety of a Child Contact Centre
This will be an urgent application meaning that mediation will not be necessary - and you can then issue it the day you collect the children so that there is no accusation f abduction.
The form you need is a C100 and the fee is £215
I hope that this is of assistance - please ask if you need further details
