JPMorgan Chase will pay $136 million — including $693,013 to Louisiana — to settle claims that it used illegal tactics to go after delinquent credit card borrowers.

The Consumer Financial Protection Bureau alleged the bank illegally relied on robo-signing — signing mass quantities of documents without verifying the data in those accounts — and provided inaccurate information to third-party debt collectors when it sold the accounts.

The bureau also said Chase filed misleading lawsuits using inaccurate information to obtain debt collection judgments — on accounts that were paid off, discharged in bankruptcy or otherwise were uncollectable.

“Chase sold bad credit card debt and robo-signed documents in violation of law,” CFPB Director Richard Cordray said.

Under the terms of the agreement, JPMorgan Chase & Co. will refund at least $50 million to affected consumers and pay $136 million in fines to the bureau, 47 states and District of Columbia. The bank will permanently halt collecting on 528,000 accounts.

It will have to pay a separate $30 million penalty to the Office of the Comptroller of Currency.

“Consumers in Louisiana and across the country were subject to collections actions based on information that was incorrect or just out-and-out wrong,” Louisiana Attorney General Buddy Caldwell said.

“We are glad to see that the practices have stopped, and I believe this action is appropriate to hold the company accountable for its past practices, provide restitution to harmed consumers and ensure that it does not happen again.”

The agreement also will include changes to the way Chase will collect delinquent accounts. Any accounts that Chase sells to debt collection agencies will be unable to be resold to other agencies.

Chase also will have to verify individually any account it sells to a debt collection agency confirming the debts are valid, and it will have to notify the delinquent customer that the debt was sold, among other changes.

JPMorgan had reached a similar, earlier agreement with federal regulators regarding its debt collection practices in 2013. The New York bank has refunded more than $50 million to consumers under that order.

“We are pleased to resolve these legacy issues,” the bank said in a statement.

Federal regulators and state attorneys general said that while this settlement was against Chase, other banks and collection agencies used similar practices as well.

Illinois Attorney General Lisa Madigan said the agreement “could be used as a template to reform the debt collection industry.”

The three states that were not part of the settlement were California, Mississippi and Wyoming. California has litigation pending against JPMorgan.
