Marriage shouldn't be a government thing
That's the whole point of marriage these days for most people.
There should be this easy system:
His money
Her money
Their money
That is what I am going to do, if and when I get married [:(].
At the end of the month, we all pool together our salaries and decide on a certain percentage in order to pay off the bills/special occassions such as family vacations and Christmas.
And then the rest goes to him or her to be used to spend on stuff, so the other spouse doesn't get pissed you used your money to buy a $1000 dollar PC.
This makes divorce, if it does happen, much MUCH more easier.
But this is all lawless boundaries that I think the spouses should agree on, and if possible, sign on.
