Do most married people share bank accounts or keep their own separate ones? It seems that more often than not nuptials presume the shared marriage bed but discount keeping their money in the one place. Is there a benefit to this?

I guess if you're planning to fail in your marriage (and why wouldn't you - 3 out of 4 marriages fail these days) it may seem the most logical step. However, it may be costing you more for the privilege. It doesn't take an Einstein to calculate that two bank accounts will incur double the fees and taxes but what about the interest? Keeping one account with a reasonable balance will usually pay higher interest than two with smaller amounts.

Plus, it makes sense to keep things simple - you're on the same team anyway.
