hello i can help you
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 long has he been out of the UK?
Is he definitely going to return?
Have you reported his latest threats to the police?
Will you have any warning that he is on his way back to the UK?
When was the last incidence of violence?
My apologies for the delay
You can apply for what is called a "Non Molestation Order" to prevent him from coming to your home
You can apply for an Order without him being notified and a temporary Order can be made - but there will then have to be another hearing where he will be able to object (not that he has a good case)
You can read more here
and you can get help form this charity
I hope that this is of assistance - please ask if you need further details
