N.C. Gen. Stat. § 22B-2: Contracts to improve real property.

A provision in any contract, subcontract, or purchase order for the improvement of real property in this State, or the providing of materials therefor, is void and against public policy if it makes the contract, subcontract, or purchase order subject to the laws of another state, or provides that the exclusive forum for any litigation, arbitration, or other dispute resolution process is located in another state.
