Splitting pensions fairly

My ex partner and I separated in July 2022. We were married on 28th July 2015. We are both female, we both worked and on average earned the same. My ex partner works for the NHS. I did not know they were not contributing to their pension and as a result their pot is much smaller. Is there any case law relating to the choice to not contribute even though always working and how that is accounted for? There are no children and no one had to not work in the relationship

thank you

Did you live together before you married?
What other assets do you have between you?
What are your ages and incomes?
Are there any debts/loans to consider?
How much are the pensions worth (CETV)?
The pensions need to be seen in the context of the whole financial picture. Arguably you both benefited from the money that didn't go into the pension. It may be possible to offset disparity in pension provision against capital assets - ie swap future pension for cash now.
You could argue that only pension accrued during the relationship should be considered as part of the matrimonial pot. Depending on the size of the pot, you may need an actuary's report.
