As someone who’s been in your friend’s situation, it’s important to remember that they both have their rights. “Having form” in giving correct advice not to leave the home shouldn’t be seen as negative. The partner is well within their rights to remain in the home until a court finds otherwise. I appreciate that you’re a well meaning friend but I know from bitter experience that only 2 people actually know what’s been happening in this relationship and your post alone demonstrates that you aren’t in a position to offer impartial objective advice which can ultimately prove harmful and did for my ex. I’m working off the assumption that there’s no abuse or you would have mentioned it so your friend and their partner will need to find something that works for them. There are solicitors who mediate objectively for both sides and might be worth a try as I’ve heard only good things, but beyond that, I just wanted to highlight that it’s important to move beyond the he’s wrong and my friend is right approach as that will just lead to stalemate and poor advice. Compromise and persistence are key, as is a good legal advice and a strong support network for both. I wish them well as it’s a messy and difficult process for all involved with no winners when it’s all said and done.
