N.C. Gen. Stat. § 1-661

Nothing in this Article prohibits the parties from using, by mutual agreement, other forms of nonadversarial alternate dispute resolution, including mediation, to reach a settlement on any of the issues included in the collaborative law participation agreement. The parties' collaborative lawyers may also serve as counsel for any form of nonadversarial alternate dispute resolution pursued as part of the collaborative law participation agreement so long as it is not a proceeding as that term is defined in G.S. 1-642(10).
