Hi SD - Sweden is simple in that regard - 50-50 split of goods, no alimony, possibly child support, but only for 2 years, until d16 is 18. Of course I will support d16 further.
Getting unmarried is as simple as signing a form when both agree and sending this to the local court, plus a small processing fee. Sweden ascribes no special status to marriage taxwise, and everyone files individually. Gender is irrelevant.
Legally divorced is simple - it is more the emotional and practical stuff to follow that concerns me. I think I've already done a lot of grieving, though perhaps something hidden will emerge. A new person deserves to be loved on a clean background.
