(a) If the estate is otherwise sufficient, property specifically devised is not used to satisfy rights to exempt property. Subject to this restriction, the surviving spouse, the guardians or conservators of the minor children, or children who are adults may select property of the estate as exempt property. The personal representative may make these selections if the surviving spouse, the children, or the guardians or conservators of the minor children are unable or fail to do so within a reasonable time or if there are no guardians or conservators of the minor children. The personal representative may execute an instrument or deed of distribution to establish the ownership of property taken as exempt property. The personal representative or any interested person aggrieved by any selection, determination, payment, proposed payment, or failure to act under this section may make application to the court for appropriate relief.

(b) The surviving spouse or the minor or dependent child, and the minor’s guardian or conservator acting for him, as the case may be, may claim a share of exempt property as provided in this part by filing in the court and mailing or delivering to the personal representative, if any, a claim for such share within eight months after the date of death, or within six months after the probate of the decedent‘s will, whichever limitation last expires.
