I work, he doesn't, no DC. We are married and both late 40s/early 50s.
One way or another ultimately I pay for everything but I earn a good salary so money is rarely a concern. I'm happy for DH to take on the domestic side of our marriage.
We have a joint account for bills which I pay into monthly based on expected annual costs (when he was working it was both of us pro-rata, now I cover it all.). I overpay so that builds up a decent savings buffer for holidays and emergencies.
I pay mortgage money into his account and he pays the mortage. We do it that way because it's a premium account which gives us travel and gadget insurance but he needs to run a minimum amount through his account each month to keep it.
We own equal shares in the house which has a decent amount of equity.
He runs the house, life admin etc. He puts grocery, shared travel, holidays etc on a joint credit card which I pay off each month. He'll decide who we use for insurance, utilities and so on and move the direct debits around as needed.
He gets £300 a month from me for personal spending and will just use the joint card if he needs anything more. I've asked him if he wants more cash in his own name but he says no, he doesn't usually spend it anyway and he's got access to plenty of money on the joint card and joint account if he needs it. Honestly, I think he feels a little like he shouldn't take it because I earn it, but I'm comfortable that even if most of the money is in my name should the worst happen he'll inherit it anyway, and if (god forbid) we go crazy and decide to divorce each other he will have a claim on my assets so I think he's protected for both scenarios even if the money's not in his own name.
We are both very low maintenance - we have one shared 16 year old car that does about 2k a year, high street/second hand clothes and personal grooming means keeping clean not maintaining an aesthetic image :) We sometimes spend money on travel but not recently for obvious reasons.
If we go out, stay in a hotel etc it'll go on the joint card so either one of us might "pay" at the time, but I'll pay the CC bill.
He has a hobby that involves a lot of kit but also has a strong second hand market, so he tends to fund the hobby by selling old kit and he enjoys that more than sitting on piles of stuff he doesn't use.
