All provisions of a will made prior to a testator's final divorce or the annulment of the testator's marriage in which no provision is made in contemplation of such event shall take effect as if the former spouse had predeceased the testator, and the provisions of Code Section 53-4-64 shall not apply with respect to the descendants of the former spouse who are not also descendants of the testator. If the testator remarries the former spouse and the testator has not revoked or amended the will that was made prior to the divorce or annulment, the remarriage shall not result in the revocation of the will and the provisions of the will that were revoked solely due to the application of this Code section shall be revived.
