When you think about divorce, you probably think of all of the emotions that come with it. In law, divorces are nothing more than the division of marriages on paper. Marriages are, at least in a legal sense, a kind of business arrangement. Marriage provides you with certain benefits, like tax deductions and certain protections, and divorce severs you from them.
The problem with divorce often happens when the emotional collides with the legal. It is very difficult to divorce without being emotional about the subject in some way, but when emotions run high and make it so that you can't make good decisions or won't negotiate, they're only hurting your case.
