With 143 million people potentially hit by Equifax Inc.'s data breach this week, there's no doubt there will lawsuits — a lot of them.

“You'll have suits in every state,” said Ben Meiselas, an attorney at Los Angeles-based Geragos & Geragos, which filed the first case in Oregon along with Michael Fuller of Olsen Daines in Portland, Oregon. Geragos & Geragos planned to file lawsuits in at least a dozen states within the next week, Meiselas said. “The full scope and magnitude is still being gathered, but it's obviously one of the largest data breaches ever and affects almost half the population of the United States. That's going to mean hundreds of lawsuits.”

Another class action was filed in Georgia, where Equifax is headquartered. On Friday, New York Attorney General Eric Schneiderman launched a formal investigation into the breach. There's also a good chance that all the Equifax lawsuits will get coordinated into multidistrict litigation.
