N.C. Gen. Stat. § 1A-1, Rule 44.1: Determination of foreign law.

A party who intends to raise an issue concerning the law of a foreign country shall give notice by pleadings or by other reasonable written notice. The court, in determining foreign law, may consider any relevant material or source, including testimony, whether or not submitted by a party or admissible under Chapter 8 of the General Statutes and State law. The court's determination shall be treated as a ruling on a question of law. (1995, c. 389, s. 5.)
