Update Your Estate Plan After Divorce in Idaho

Idaho law does some of this work for you automatically. Under Idaho Code § 15-2-508, the entry of your final divorce decree revokes every provision in your will that benefited your ex-spouse — distributions, appointments as executor, trustee nominations, guardianship designations. The law treats your ex-spouse as if they predeceased you.

Idaho Code § 15-2-804 extends that revocation to revocable trusts and payable-on-death accounts and severs joint tenancy on real estate, converting it to tenancy in common. A spouse-agent's authority under a power of attorney generally terminates when an action for dissolution, annulment, or legal separation is filed under Idaho Code § 15-12-110, unless the POA provides otherwise; review healthcare directives separately.

That's a lot of automatic protection. But "automatic" doesn't mean "sufficient," and relying on statutory revocation instead of actually updating your documents creates real problems.

Why Automatic Revocation Isn't Enough

Your contingent beneficiaries may not be who you want. When Idaho law treats your ex as predeceased, your estate passes to whoever is named as the contingent beneficiary in your will. If you never named a contingent — or if the contingent was your ex's family member — your estate could end up in probate court or go to people you didn't intend.

Institutions don't always know you're divorced. Your bank, insurance company, or trust custodian may not be aware that your divorce triggers automatic revocation under Idaho law. They may process a claim to your ex-spouse based on the documents on file, forcing your actual beneficiaries to hire an attorney and sue to recover the funds.

ERISA plans are not covered. The biggest gap: employer-sponsored retirement plans and group life insurance are governed by federal law, which generally preempts Idaho's automatic revocation statute for plan administration. Those plans generally follow the beneficiary designation on their records, subject to applicable plan or court-order requirements. (See the beneficiary update guide for details.)

What to Replace and When

Will

Draft a new post-divorce will. Even though Idaho automatically revokes your ex's share, a new will lets you:

• Name specific beneficiaries for your assets
• Designate a new personal representative (executor)
• Name guardians for minor children if something happens to you
• Account for any property settlement terms from your divorce

If you have minor children and no will, Idaho's intestacy laws determine who receives your estate and a court appoints a guardian — neither of which may match your preferences.

Revocable Living Trust

If you created a revocable trust during your marriage, Idaho Code § 15-2-804 revokes distributions to your ex and revokes their appointment as trustee. But you should execute a formal trust amendment (or complete restatement) that:

• Removes your ex as beneficiary and trustee
• Names a successor trustee
• Updates distribution provisions to reflect your post-divorce wishes
• Adjusts the trust to account for any property that was removed during the divorce settlement

Powers of Attorney

A spouse-agent's authority under a financial power of attorney generally terminates when an action for dissolution, annulment, or legal separation is filed under § 15-12-110, unless the POA provides otherwise. Review healthcare documents according to their terms. Revocation or termination isn't the same as replacement: execute new documents naming trusted agents so your choices are clear if you're incapacitated.

Execute a new durable financial power of attorney and a new healthcare directive (including a living will if you want one). Idaho's standard healthcare directive form allows you to name a healthcare agent, specify treatment preferences, and address end-of-life decisions.

Healthcare Directive / Living Will

If your ex-spouse was your designated healthcare proxy, review and revoke or replace that designation according to the directive's terms. If you don't name a replacement, Idaho's default decision-making hierarchy may apply — which may give authority to a parent, adult child, or sibling rather than the person you'd actually choose.

The Priority Order

1. Immediately: Execute new powers of attorney (financial + healthcare). You could be incapacitated tomorrow, and right now nobody has authority to act for you.
2. Within 30 days: Draft and sign a new will. If you have minor children, this is especially urgent for guardian designations.
3. Within 60 days: Amend or restate your revocable trust if you have one.
4. Ongoing: Update beneficiary designations on all employer-sponsored accounts (not covered by automatic revocation).

Do You Need an Attorney?

For a simple estate — no trusts, no business interests, no blended-family complications — you can use Idaho's statutory will form or an online will service. For anything involving trusts, significant assets, minor children from multiple relationships, or complex property settlements, an estate planning attorney provides drafting precision that templates can't match.

The Idaho After-Divorce Checklist includes an estate planning audit worksheet that maps every document to update, tracks which instruments are automatically revoked vs. which require manual action, and provides a timeline for completing each update.
