Divorce and finances

Some of the threads on gay marriage have touched peripherally on the difficulty of coming up with a rational scheme for polygamous marriages - how to divide finances during divorces and so forth.

Which made me realize that I don’t really know anything about how that works in the first place. When two people divorce in the United States, in the absence of a pre-nup resolving the question, how are their finances divided? Does it depend on what’s in whose name? If a couple has a joint savings account, is it just divided down the middle? Is there any attention paid to who earned more money within the marriage, or who brought more assets to it in the first place? How does all that stuff work?

Most U.S. states are either “community property” or “equitable distribution” states. If you do a google search on those terms, I’m sure you will find plenty of information.

As well as plenty of ads for divorce lawyers.
