Get in early: sign a prenuptial disagreement before marriage so you don't have to worry about it after.
Arrange for a divorce to be held before you get married. It is a far neater way of doing things. Hold a touching ceremony for the whole family you will be breaking up: nobody will be able to stop themselves from crying at the traditional ceremony of the Taking Back of the Engagement Rings - but who will be able to wake for the excitement that is the Cutting of the Financial Cake?
(Oh yeah, and hold a wedding and stuff after too, I guess.)
If you prepare and do things right, it will only strengthen your marriage bonds. Although you might end up having make-up sex without having anything to make-up about, which is a bit too S and M for some... I guess.
