Because you have a child to consider his financial standing is 100% your business - you need to understand how you’re going to fund your child’s childhood and beyond to be able to make informed decisions for yourself (your work, property cos it’ll effect things like what sort of mortgages you’ll be able to access with his predicted retirement date, if you wanted a loan for an extension, etc etc). I don’t mean this nastily but he’s not only going to lose a lot of “wealth” (eg assets whether it’s property, vehicles, pensions) but also possibly income with alimony and child support (albeit youngest has nearly aged out of this?) so you really need to know. It doesn’t mean getting involved in their drama and who said what or who is wrong, you just need to see the numbers for your own financial planning.need to think carefully about how I broach the subject as I’ve stayed out of the divorce stuff so far out of fear!!
Do you have a savvy friend to run this stuff past and to support you through it all? Your dad seems involved from your previous comment, maybe discuss this stuff with him too if you feel comfortable? You defs need to shake off any shame or guilt for asking as it determines the course of your life! And ngl a bloke who’s at the end of his working life about to lose at least half his assets, take on some ongoing financial obligations, has 3 financial dependents, and pay out at least 2 years worth of legal fees isn’t exactly a gold digger’s cup of tea so disregard those comments.
