My sister is getting divorced. She has been a SAHM with pretty much 100% care of her kids (18 months, 3.5) and is going to continue as the very much main carer. OH has his own business. They are early in the process but her and her OH are nowhere near in agreement on finances - they've had nothing but one totally failed mediation session.
OH is thinking from the perspective of splitting assets 50/50, but they don't have that much money between them and obviously it doesn't necessarily work that way with young children involved.
What should they do to push this on so that they are at least arguing in the right ballpark rather than from a widely differing perspective? Is this all about going to solicitors for advice, or are there calculators, books etc that would help them move it on without landing up in court? And how bad is the court option if you just can't reach agreement?
Thanks :(
