Everyone except Tiger Woods knows marriage is a commitment. But moving in together? That’s just supposed to be funzy, right? Well sure, in the beginning — but if things go south, things can get nasty. Specifically, things.

It’s not so crazy to demystify the process and go into a shacking-up sitch with a clear idea of what you both want out of it — both short- and long-term. Maybe you won’t opt for a legal agreement, but guides and workbooks abound. It’s nothing but smart to take advantage.
