North Carolina General Statutes Chapter 32A. Powers of Attorney § 32A-32. Duration of authorization; revocation

(a) An authorization to consent to health care for minor shall be automatically revoked as follows:

(b) An authorization to consent to health care for minor may be revoked at any time by the custodial parent making such authorization. The custodial parent may exercise such right of revocation by executing and acknowledging an instrument of revocation, by executing and acknowledging a subsequent authorization to consent to health care for the minor, or in any other manner in which the custodial parent is able to communicate the parent's intent to revoke. Such revocation shall become effective only upon communication by the custodial parent to the agent named in the revoked authorization.

(c) In the event of a disagreement regarding the health care for a minor child between two or more agents authorized pursuant to this Article to consent to and authorize health care for a minor, or between any such agent and a parent of the minor, whether or not the parent is a custodial parent, then any authorization to consent to health care for minor designating any person as an agent shall be revoked during the period of such disagreement, and the provisions of health care for the minor during such period shall be governed by the common law, the provisions of Article 1A of Chapter 90, and other provisions of law, as if no authorization to consent to health care for minor had been executed.

(d) An authorization to consent to health care for minor shall not be affected by the subsequent incapacity or mental incompetence of the custodial parent making such authorization.
