That's already the reality for some same-sex marriage pioneers: Gay and lesbian couples in unsuccessful domestic partnerships and those whose 2008 marriages didn't last have already learned the ropes in family court, where attorneys' fees can easily soar past $20,000.
Last month, the U.S. Supreme Court effectively overturned California's voter-approved ban on same-sex marriage and handed down a sweeping Defense of Marriage Act ruling that allows legally married gay and lesbian couples across the country to receive federal benefits.
With those landmark actions, legal experts are already warning same-sex couples that hard-fought civil rights can also come with hefty contractual consequences.
