A California legal professional has sued payment platform PayPal Inc. for violating attorney-client privilege by allowing credit card companies to reverse attorney fee transactions.

Todd White, a paralegal based in San Diego, has brought claims of breach of contract, fraud and unlawful business practices against the company after a client asked a credit card company to cancel the payment of attorney fees to White on PayPal, according to the complaint filed Friday in the U.S. District Court for the Northern District of California. The purchaser asked to rescind the charge, reporting “problems with the payment.”
