Ignore the criticism.
Whilst most women of your age (I am slightly older) worked at some point, I do know a few that didn’t, like you they had husbands in high paid careers. I also have relatives that are slightly older than you (late 60s and early 70s) who married at 19/20 like you, and then have never worked. It was fairly common back in the day.
In answer to your main question, yes you will get half of the joint pension value, put into a pension of your own. The calculations will be done by actuaries, and then you will probably be advised to see a Financial advisor to decide where exactly you put the pension money (you won’t get it as cash, but will be able to access the pension straight away given your age). Ignore anything your husband says to the contrary, he will get a shock when you both go into financial mediation (which I think is compulsory).
You also need to see how much state pension you have accrued, hopefully you claimed child benefit when the kids were young which would have given you NI credits. This could have a bearing on your final settlement too.
A close friend of my best friend is going through similar at moment, of interest as my best friend has lent her money whilst she is sorting divorce finances out, and thus is keen for them to reach a financial settlement and she get her money back.
It has taken a while, due to pensions being from local govt and slow to give valuations. They have had a number of financial mediation meetings together and apart with solicitors, to thrash out the details of the financial settlement. If that can’t be done, I believe it will go before a judge.
Unfortunately you will not get any of his inheritance. The friend of a friend above inherited a few months before they split, and she hasn’t been made to share it with ex husband.
Similar with income, you will be expected to earn it, but if the pension is large enough, you might get a decent monthly payment straight away.
Please get yourself some decent legal advise, that is crucial.
