Things are getting close to coming to a head and I'm trying to get my ducks in a row. When a friend split from her husband a few years ago, our other friend who is a solicitor advised getting a legal agreement in place to save hassle going forward and to avoid having to constantly ask her Exh for money for things or to make arrangements. The idea being that there would be a legal plan in place that both parties had signed up to. I like that idea, primarily because a complete inability to communicate with each other while in the marriage doesn't bode well for doing so when separated. We have two DC, ages 15 & 12. I would want them with me post separation as much as possible but am aware that could end up being 50/50 if that's what he pushes for. House will be sold and equity split. If it's 50/50 there will be no maintenance due but I know that I'll end up paying for most of their stuff and that we will be supporting them if they go to uni. Ideally, I want to minimise the discussions about money post-split but not end up covering for him financially when he's already the higher earner by some way. I have no idea how much legal fees would cost. And I'm wondering if it's worth it?
