(1) An individual who fails to survive the decedent by one hundred twenty (120) hours is deemed to have predeceased the decedent for purposes of the homestead allowance, year's support allowance, exempt property, elective share and intestate succession, and the decedent's heirs are determined accordingly.
(2) A devisee who fails to survive the testator by one hundred twenty (120) hours is deemed to have predeceased the testator, unless the will of the decedent contains language dealing explicitly with simultaneous deaths or deaths in a common disaster or requiring that the devisee survive by a stated period of time in order to take under the will.
(3) If it is not established by clear and convincing evidence that an individual who would otherwise be an heir or devisee survived the decedent by one hundred twenty (120) hours, it is deemed that such individual failed to survive for the required period. This section is not to be applied if its application would result in property of any nature escheating to the state.
