Unlike a general denial, verified denials must be specifically pleaded and substantiated by affidavit. If the defendant does not provide verification of a claim, then the plaintiff is released from the burden of proof. The specific defenses in Texas that must be verified include the following. (Tex. R. Civ. P. 93 and Tex. R. Civ. P. 185)
Just as it sounds, a general denial says that the defendant disagrees overall with the plaintiff’s claims. Instead of denying any specific allegation, the plaintiff denies everything alleged in the petition.
