Likely outcome

Hello all posted recently on other boards and received v helpful advice. Would now like advice please on finances. Do hope by the way to be able to reciprocate in the future!
Here goes its a bit complicated...
Me and h are both 50 been together since 19 met at uni. We were two kids who were in love. Moving on we now have children of 17 and 14. Our relationship has been crap since we had kids. Not really sure why. I had bad pregnancies and 2 caesareans and postnatal depression. He always really wanted children to be honest more than me. Since birth of first things changed balance of power and control shifted to him. With my agreement he went all out for the career and income and managed it! I thought I was looking after house and children for good of us all - the family. Have never been able to rely on him to look after kids at all so its all been down to me.Felt like being a single parent for long time before we split.
Years down the line now we have been separated for 5 years going through divorce. He has been living with new partner last 2 years. Kids have stayed with me - what a surprise.
Hope anyone is still reading! Heres the bare bones.
X2b salary approx £57K car provided fuel paid for services etc, phone and mobile and computer paid for.
My income 15k part time still doingjob I was in 20 years ago. His pension CETV £186k mine £88k. Equity in FMH about £150k. He has bought house since split which he now rents out. About £30k equity. X and np are currently renting 4 bed house. Can't understand why they need a house this large have no kids between them and only ever have maximum 2 both boys stopping over for 'contact'.
Anyway x2b intends us to go to court. My last offer to him was- I will give you £30k and accept CSA rates. No spousal maintencnce or pension split. No claim on other house. And he said no. So he has filed for ancillary relief. Any opinions please sorry for such a long post!

the bare bones of it all is that nearly all assets pay, pensions, houses anything of value is put into the pot and then shared out starting 50/50 you have kids so your share rises to possibley 65/35 in your favour + maint for kids.

NO cash to change hands untill the court has agreed its fare as the reprocussions can and will be felt long after, like my 8 years

If you go to court, he will have to declare all assets, regardless of what he 'thinks' is his. You are still married I assume?

I think you could expect a 65%-35% or 70%-30% split in your favour. Certainly not less than 50-50% judging by what's been posted on this site.

His housing needs are met, (don't worry about him renting a big house, his needs are met, which frees up your MH for you and the kids) this gives you a better bargaining power, since he already owns elsewhere.

Courts sometimes offset Pensions in exchange for a greater percentage of the house. By the time you reach retirement, the kids would've gone, and you could then downsize.
