We first consider whether the trial court erred in dismissing the amended complaint on the grounds that Calvert Insurance Company *530is an excess insurer. Royal asserts that the trial court erred in deviating from the face of the pleadings by considering oral representations regarding the terms of Calvert’s liability policy with respect to an alleged $100,000 Self-Insured Retention Endorsement. Royal also argues that the motion to add Calvert as a necessary party, which alleged that Calvert insured the rental vehicle “for claims in excess of $100,000.00,” should not be considered because it was beyond the face of the complaint and amended complaint. Royal maintains that the trial court could not have made a correct conclusion of law regarding the meaning of the Calvert policy without examining the contents and language of the policy. Royal concludes that since no copy of the policy was entered into the record, the judge apparently relied upon counsel’s oral representations as to the terms and conditions of that policy.
Calvert argues that the Court properly considered that Calvert was an excess insurer because the motion to add Calvert as a necessary party was a part of the pleadings. Calvert alternatively argues that if this Court should determine that the pleadings should be limited to the complaint, then the motion to add Calvert as a party should be considered as part of the amended complaint, because “the nexus between the two [documents] is so intimate that it was proper for the trial court to consider the two documents in tandem when ruling . . . .” Finally, Calvert argues that if the trial court erroneously granted Calvert’s Rule 12(b)(6) motion based upon the motion to add Calvert, then the trial court’s ruling should be upheld as a Rule 12(c) motion for judgment on the pleadings.
On this record, we conclude that because the trial court considered evidence outside the pleadings, Calvert’s motion to dismiss should not have been granted and is reversed. In ruling on a motion to dismiss, a court properly may consider only evidence contained in or asserted in the pleadings. See American Angus Ass’n v. Sysco Corp., 865 F.Supp. 1174, 1175 (W.D.N.C. 1993); State of Tenn. on Behalf of Tennessee Dept. of Health and Environment v. Environmental Management Com’n of State of N.C., 78 N.C. App. 763, 765, 338 S.E.2d 781, 782 (1986). The motion to add Calvert as a party was not part of the pleadings and the statement in the motion that Calvert was an excess insurer should not have been considered. See W. Brian Howell, Shuford North Carolina Civil Practice and Procedure § 7-5 (4th Ed. 1992) (“. . . a motion is not considered a pleading, as indicated by the delineation between Rule 7(a) regarding pleadings and Rule 7(b) regarding motions.”). Accordingly, the *531trial court’s order dismissing the amended complaint pursuant to Rule 12(b)(6) was erroneous and is reversed. Based on our disposition of this issue, we need not address the remaining issues raised on appeal.
Reversed and remanded.
Judges WYNN and WALKER concur.
