This subsection does not grant to any person the right to cancel a preneed funeral contract executed pursuant to Article 13D of Chapter 90 of the General Statutes, to prohibit the substitution of a preneed licensee as authorized under G.S.90-210.63, or to permit modification of preneed contracts under G.S.90-210.63A. If an individual is incompetent at the time of the decedent's death, the individual shall be treated as if he or she predeceased the decedent. An attending physician may certify the incompetence of an individual and the certification shall apply to the rights under this section only. Any individual under this section may waive his or her rights under this subsection by any written statement notarized by a notary public or signed by two witnesses.
