The ubiquity of electronic data is making it harder for troubled couples to keep a secret stash—and it's sending divorce attorneys laughing all the way to the bank. 

The Journal's Veronica Dagger describes how the paper trail has evolved into a password-protected smartphone or Facebook page that attorneys use to glean evidence: 

"The numbers ... confirm that technology is playing a growing role in uncovering that double-dealing.

In 2010, 81% of the members in the American Academy of Matrimonial Lawyers said they had seen an increase over the past five years in the use of evidence from social-networking sites.

This year, 92% said that over the past three years, they have seen an increase in the number of cases using evidence taken from smartphones." 

Snooping has also gotten easier for couples cheating on each other because the data's so easy to trace. One LinkedIn profile led a suspicious husband to millions in hidden assets, while a forensic expert sees deceptive spouses set up PayPals account to fund their affair.
