North Carolina General Statutes Chapter 28A. Administration of Decedents' Estates § 28A-24-2. Requirement of survival by 120 hours

(a) Except as otherwise provided in this Article, where the title to property, the devolution of property, the right to elect an interest in property, or any other right or benefit depends upon an individual's survivorship of the death of another individual, an individual who is not established by clear and convincing evidence to have survived the other individual by at least 120 hours is deemed to have predeceased the other individual.

(b) If the language of the governing instrument disposes of property in such a way that two or more beneficiaries are designated to take alternatively by reason of surviving each other and it is not established by clear and convincing evidence that any such beneficiary has survived any other such beneficiary by at least 120 hours, the property shall be divided into as many equal shares as there are alternative beneficiaries, and these shares shall be distributed respectively to each such beneficiary's estate.

(c) If the language of the governing instrument disposes of property in such a way that it is to be distributed to the member or members of a class who survived an individual, each member of the class will be deemed to have survived that individual by at least 120 hours unless it is established by clear and convincing evidence that the individual survived the class member or members by at least 120 hours.
