Sounds like a boon for lawyers:
A growing number of unmarried couples are seeking similar legal protections through cohabitation agreements. These legally-binding contracts, which are drawn up by an attorney, protect each person’s assets, address child custody issues and determine support obligations, much like prenuptial agreements do.
“We’ve seen a real dramatic increase,” said Ken Altshuler, president of the American Academy of Matrimonial Lawyers, or AAML. “A lot more people are delaying, or forgoing, marriage and people are realizing as you get older, you have more things to protect.”
I suppose this is a logical progression: In 1960, 72% of all adults ages 18 and older were married, and today just 51% are.
