A new frontier in civil unions: A notary public in Brazil has sanctioned a three-person union among a man and two women, reports the BBC. The three don't appear to be publicity seekers out to take a stand—in fact, this happened months ago and just came to light this week. The trio has lived together in Rio for three years, sharing the humdrum stuff of life like a joint checking account to pay the bills. They sought the union for legal protection in case one of the three dies.
