(a) The surviving spouse’s election of his elective share does not affect the share of the surviving spouse under the provisions of the decedent‘s will or intestate succession unless the surviving spouse also expressly renounces in the petition for an elective share the benefit of all or any of the provisions. If any provision is so renounced, the property or other benefit which would otherwise have passed to the surviving spouse thereunder is treated, subject to contribution under section 15-2-207(b), Idaho Code, as if the surviving spouse had predeceased the testator.
(b) A surviving spouse is entitled to homestead allowance and exempt property whether or not he elects to take an elective share and whether or not he renounces the benefits conferred upon him by the will except that, if it clearly appears from the will that a provision therein made for the surviving spouse was intended to be in lieu of these rights, he is not so entitled if he does not renounce the provision so made for him in the will.
