OP - for starters - do not agree to anything related to financials without getting advice.
Do NOT put the house on the market, or go along with any proposed sales.
As your earning power is different, your share of marital assets can be more than 50%.
Secondly - you also don’t have to agree to 50/50 child arrangements split. Not at this point anyway.
When my H (now ex) said he wanted 50/50 - and at that point I also was a SAHM for years - I said he’ll need to actually demonstrate it works, that he can do it.
I also said it’ll have to mean ALL child related tasks - not just the fun bits. So - I was going to make a list of everything involved - medical, clothing, footware, playdates, activities, supplies, crafts, mental load, etc and he was going to take half of it as HIS responsibility.
He didn’t think about it before - but when i laid it out - he realised he can’t really take it on with his job.
And in general - i said i will fight for what is best for the kids and he’ll have to prove in court it’s better for kids to be with a nanny rather than me. He knew i meant it.
With my ex - it wasn’t an attempt to avoid maintenance - it was because he was scared to lose his kids.
So - i suggested a flexible schedule that will give him quality time, taking into account his work pattern. And i have always been flexible to facilitate contact.
Next point - depending on his income - you may be able to get some maintenance while you are re-entering workforce and while your youngest is in primary.
As much as possible - the court tries to leave divorcing spouses in similar financial position. Which includes assets, and takes into account pensions and earning potential.
So - his ability to get a mortgage post split, for eg - is something you won’t have as your income will be lower and you’ll be only part time while youngest in small. This are some of the reasons women get a larger than 50% share of assets, for eg.
He may also need to pay child maintenance - if he is above CMS threshold.
There are many nuances to the financial settlements - so - don’t assume the worst just yet, and don’t agree anything.
Tell him - it’ll all have to be done properly with solicitors involved.
Don't let him bully you into anything!!!!
He probably will try - they all do.
