Normally in a 12b6 motion, the court assumes the facts stated in the complaint are true for purposes of that motion only. There's no need to attach exhibits to prove their accuracy.
I'm not sure if that changes when a verified complaint is filed, but Tranquility may be able to shed some more light on that issue.
In the motion, has the opposing party challenged any of your facts as being false? Or are they merely asserting that the facts which you did allege do not create legal liability?
The opposing party has not challenged any of my complaint's facts as false but merely assert that they do not create legal liability.
