There is no issue with moving back if your ex agrees. If she doesn''t you would need to apply for an occupation order (more legal fees?) and your occupation rights would be balanced against her rights to privacy and a family life, alternative accommodation available, the financial means of the parties to pay for accommodation and the way each party has behaved.
You can''t just force your way in, you don''t live there any more and it''s still your wife''s home. Your rights of ownership need to be balanced against your wife''s rights under human rights legislation to privacy and a family life. The factors that courts take into account
when granting an occupation order are outlined in s33(6) Family Law Act 1996;
What would you think if the positions were reversed? Lets say you were living in the house, and your wife moved out 2 years ago, you got a divorce and a Clean Break. Then 2 years later she just decided she wanted to move back?
I doubt you would be very happy with that situation, or welcome her with open arms? She says she is broke and has nowhere else to go, I expect your response would be "not my problem"?
No, I am sorry but unless your ex wife agrees, I don''t think you have a cat in hell''s chance.
