Who signs an A/N/D/ petition and whether it is properly verified determines if the court has subject matter jurisdiction over the proceeding. Without subject matter jurisdiction, the court has no authority to act and any judgment entered is void. In re T.R.P., 360 N.C. 588 (2006). Because subject matter jurisdiction can be raised at any time, even for the first time on appeal, and it cannot be waived or consented to, a county could discover weeks, months, or years after the action is commenced that all its orders in the action are void. This is problematic for many reasons.
