Not split yet, but considering.
I have spent 20 years building up a pension when working, always paid at least minimum amount into it and switched to paying much more through salary sacrifice 6 months ago.
I'm the higher earner and I contribute considerably more into the family joint money every month. Dh not as career driven, works in a hobby job that he enjoys.
I've always done majority of childcare. Kids would likely live with me but obviously spend time with him if we split. I don't think he'd want 50/50, as he struggles having his kids alone, but if he does then of course he's entitled to see them and they would want to see dh.
I've nagged him for years about a pension, because he didn't have one (company didn't have a policy). He got one when it became compulsory for companies to offer one and he's paid minimum since.
At any point he could have changed careers, I said I'd support any retraining if he desired, but he was insistent on doing the niche hobby lower paid career so I've always accepted that although it's been a frustration of mine.
Will the courts ever take into account one party's previous pure reticence to be responsible and get a pension, when deciding on division of pension? He doesn't have much in his because he assumed at some point he'd buy a nest egg property with me that would look after him in old age. It's so frustrating and I don't want to lose my pension because of his complete inability to be an adult.
