Hi, thanks for your question. Whose name is ***** ***** in and has their been a court approved financial settlement?
Thank you for your question
My name is ***** ***** I have been a family lawyer for more than 30 years.
If your new partner moves in then your ex cannot force her to leave UNLESS your ex is there an you are not.
At that point your partner would have no right to remain in the property when asked to leave.
So assuming that your ex is not living in the property (if so then NO your new partner cannot live with you) then the gamble is how often will she attend the property when you are now there to force your new partner to leave
Please ask if you need further details
