Short answer: Divorce automatically revokes most provisions favoring your ex-spouse - in your will, POA, and many beneficiary designations - under Idaho Code § 15-2-804. But the statute has gaps (notably employer retirement plans), so we recommend that you update everything directly. And nothing changes until the decree is final.
What Idaho's statute does at divorce: § 15-2-804 treats your ex - and your ex's relatives - as having predeceased you for purposes of revocable transfers: gifts in wills and revocable trusts, beneficiary designations, and appointments as personal representative, trustee, or agent are revoked, and joint tenancies with the ex are severed into tenancy in common. It's a sensible safety net for people who never update their documents.
Where the safety net has holes:
- Employer retirement plans (401(k)s, employer life insurance): federal ERISA law preempts the Idaho statute - the plan pays the named ex-spouse. Idaho gives your heirs a lawsuit to claw it back; your heirs would rather have the right name on the form.
- Irrevocable designations, property settlements, and anything your divorce decree requires you to maintain (e.g., life insurance for child support security) are unaffected - follow the decree.
- Timing: the statute operates at the final decree. During separation and a pending divorce, your estranged spouse remains your heir, your agent, and your beneficiary. If incapacity or death strikes mid-divorce, the person you're divorcing may hold every lever.
The practical checklist at separation or filing: new will and (if any) trust amendment; new financial POA and Advance Care Planning Document naming someone other than your spouse; beneficiary updates on everything not restricted by court rules during the case (ask your family law attorney first - automatic temporary orders can limit changes); and after the decree, a full audit including the ERISA accounts the statute can't reach.
Because we practice both family law and estate planning, we can handle the divorce and the re-planning as one coordinated engagement - most family law firms simply don't, and the gap is where these problems live.
