(a) If a second will which, had it remained effective at death, would have revoked the first will in whole or in part, is thereafter revoked by acts under Section 43-8-136, the first will is revoked in whole or in part unless it is evident from the circumstances of the revocation of the second will or from testator’s contemporary or subsequent declarations in writing, signed by the testator and attested as prescribed in Section 43-8-131, that he or she intended the first will to take effect as executed.
(b) If a second will which, had it remained effective at death, would have revoked the first will in whole or in part, is thereafter revoked by a third will, the first will is revoked in whole or in part, except to the extent it appears from the terms of the third will that the testator intended the first will to take effect.
