Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
What has the pattern of contact been until now?
Can the child remain at the same school?
Prior to this week what overnight contact had the father had with the children?
Is the father proposing to move?
Assuming his name is ***** ***** birth certificate then the father has as much right to have the child in his care as the mother does.
On that basis I am afraid that your daughter and her ex are going to have to negotiate on the arrangements that are made for the children - using Family mediation
www.familymediationcouncil.org.uk if need be.
If no agreement can be reached and the father refuses to return the child then your daughter can apply to the court for an Order that the child spends the majority of time in her care.
The fact that the father has no suitable accommodation - and him having the child means separating two small children makes it unlikely that the Court would in fact endorse what the father is asking for.
At 7 your grandson is too young for his wishes to have ant great weight as he is too young to understand all the ramifications involved.
The starting point is for your daughter to make arrangements to start mediation
I hope that this is of assistance - please ask if you need further details
You are most welcome - I hope all goes well?
