Joint account, separate own accounts, and we also do multiple accounts for different purposes though a lot of people don't.
Our income goes into our own accounts. Child benefit goes into joint account.
Major budget spreadsheet is agreed by both of us and maintained at home as often as needed (we review it at least every six months, usually more often, as changes come up). It is recorded month by month and is forecast ahead up to a year depending on when we know changes are due.
I put a note on my phone (my current cheap Nokia will only let me do very short reminders, but I make it work) showing the balance left in my account, total spending still planned for the month, all the individual things that I know are either spent or going to be spent including cheques obviously, and then I adjust it almost every day - I usually phone my bank on the way in to work on the bus and edit the reminder to show how I'm doing. That way I can't get complacent when my pay goes in because I know that every penny is accounted for already!
As soon as my pay goes in to my account, standing orders go out to the joint account for household bills, holiday account, ds's savings account, car saver account, non-monthly spending account, and the contingency account. What's left in my account is for me to spend. The same for dh, we have an equal amount of spending money, but his income is much less, so his contribution to the joint account is small, and he pays into an ISA for a pension separately whereas mine is deducted from my pay. DH does the food shopping, so a weekly standing order from the joint account pays back into his account.
The non-monthly spending account covers ds's after school activities and clubs, school lunches, hair for all of us, clothes for me and ds, Christmas, all birthday presents and holiday childcare-type activities - it's quite substantial. Holiday account covers holidays including fuel costs to visit family. Contingency account we aim to build up towards 6 months slush fund against loss of job, but we haven't got there yet as we also use it to replace things that break.
