Whatever he does, don’t leave the house without advice.
I went through divorce nearly 20 years ago, we split on good terms and she (and the kids moved in with her b/f) – I kept the house, although it was pretty much +100% owned by the Building Society (late 80’s crash).
We never paid for advice, just had the solicitor draw up the legals’ – and no CSA since either – I’ve always paid whatever was needed.
But it does need both sides to want to – lucky she’d seen the CSA from the other side, with her b/f’s ex 🙂
EDIT – and we split up the stuff using a combination of which side of the family had bought it and/or who needed it – only arguement was over the dishwasher.
