Chase recently stopped allowing customers to open joint credit cards. Instead, customers must open an individual account and add their spouse, partner, or anyone else as an authorized user.
As joint cardholders, both parties to the account are equally liable for the amount owed. However, the primary account holder is liable when there is an authorized user on the card.
Chase is not the first to pull the plug on joint credit cards. HSBC and Capital One both stopped offering joint credit cards in the past 10 years. American Express has never allowed joint account holders.
Bank of America, Wells Fargo, U.S. Bank and Discover still provide customers with the joint credit card option.
