Cool I'm sorry it ended this way. Now go back to the solicitor and get the division of assets, child support and custody sorted out. With the lockdown about to end, he will get busy. You can do most of this on the telephone. Your top priority now is to protect your children. Why not see if you can stay in the house, at least for a while? Get those locks changed tomorrow before he decides to move back in. Much harder to get him out than keep him out.

3 adult children
Divorced - he was a serial adulterer
