Firstly, when I say "the Court" I don't mean we'll automatically go to Court - but it if what solicitors will think of, if you're in the agreement stage, and will always consider.
So, the Court will always want to go for a 'clean break'. If it's for the kids, then it's not spousal maintenance anyway. It may be that you decide, or the Court decides, that the asset 50/50 split actually ISN'T the way forward after all because of what the kids need and they might award you more (and don't forget pensions, for the love of god) to ensure that you have enough readies to cover the kids' needs (fees, uni etc). You could be looking at a 65/35 split.
You too have a good earning capacity so spousal maintenance just won't be a thing I reckon.
Speak with a solicitor, get the lay of the land. I hope you can both figure it out without a need for too much input from sols, but high earners usually do require input from sols and IFAs, pensions people etc due to the sums involved - and that is the way it should be.
Ensure your financial order is first thing on your list, the rest can follow.
There's a good podcast I've heard, "No As We Planned". This isn't just about how to survive a divorce and bad behaviours etc, but they have legal people on, divorce coaches and relationship experts. It's an easy listen and some of it makes me absolutely howl with laughter - it wouldn't be a lot of people's first pick but it's been a revelation!
The Legal Queen is also good on insta/tiktok if you want some background to listen to and pick up on, but ideally you'll take your advice from a local and recommended solicitor who is used to dealing with high new worth people.
Good luck.
