It turns out the kiss of death for marriages might be more like a poke.
A third of all divorce filings in 2011 contained the word "Facebook," according to Divorce Online. And more than 80 percent of U.S. divorce attorneys say social networking in divorce proceedings is on the rise, according to the American Academy of Matrimonial Lawyers.
Divorce lawyer Marian Rosen, who practices in Houston, said she's increasingly seen social media cited in divorce proceedings and child custody battles.
"We've had instances where they pull up Facebook in the course of a deposition," Rosen told ABC News, adding that in addition to proving infidelity, she's seen cases in which children's profiles are cited as evidence to suggest bad parenting. "Once it's out there for the world, it's very difficult … to erase from the past. There are going to be trails that can be followed."
