Yes, unless you file an injured spouse form.

Form 8379 is filed by one spouse (the injured spouse) on a jointly filed tax return when the joint overpayment was (or is expected to be) applied (offset) to a past-due obligation of the other spouse. By filing Form 8379, the injured spouse may be able to get back his or her share of the joint refund.
