No, only one owner is needed to close a joint account.

When closing a consumer checking, savings and money market accounts, your account will be placed in a “pending closure” status for 10 business days. During this time, we’ll allow pending deposits and debit card transactions, that you authorized prior to the closure request, to post to your account.

• If your account was closed with a negative balance, it will stay in a "pending to close" status after the 10 business days. It will only completely close once the balance is brought to zero or a positive balance.
• If you’re closing a credit card, you will still be responsible to pay any remaining balance. 

More information

Closed and pending closure accounts* are not accessible using online or mobile banking. This includes accessing statements, viewing the history, and other digital services.

* Exception: You can access newly closed mortgage accounts through online banking for approximately one week. After that, they will be visible but cannot be accessed until fully closed and removed. This could take up to one year.
