CONTRIBUTED CONTENT: Getting divorced? Idaho law handles part of your estate plan automatically — but not all of it

Divorce is already a legal and emotional process with a long checklist. Updating an estate plan often falls to the bottom of that list — or off it entirely. Idaho law offers a safety net here that many people don’t know exists, but that safety net has real gaps, and relying on it completely can leave your plan in worse shape than you’d expect.

The Automatic Protection Idaho Law Provides 

Under Idaho Code § 15-2-804, when a marriage ends in divorce or annulment, Idaho law automatically revokes certain provisions in your existing estate planning documents that favor your former spouse — even if you never got around to updating the paperwork yourself. 

Specifically, this statute automatically cancels: 

• Gifts to your former spouse in your will, treating your ex as if they died before you for purposes of that inheritance. 

• Any power of appointment given to your former spouse in your governing documents. 

• Your former spouse’s nomination as executor, trustee, guardian, or conservator in your will or other governing instruments. 

• Beneficiary designations on many nonprobate assets, such as payable-on-death accounts, where your former spouse was named. 

In each case, the law treats your ex-spouse as though they didn’t survive you, so the gift or nomination passes to the next person in line under your documents, rather than to your former spouse by default. 

Where This Protection Doesn’t Reach 

This is the part that catches people off guard. Idaho’s automatic revocation statute has real limits, and several categories of assets and documents fall outside it entirely. 

Retirement accounts governed by federal law are a major exception. Employer-sponsored plans like a 401(k) are governed by ERISA, a federal law, and federal law generally preempts state revocation-by-divorce statutes for these accounts. The U.S. Supreme Court addressed this directly in Egelhoff v. Egelhoff, holding that ERISA plan administrators must pay benefits to whoever is named as beneficiary on the plan’s own records — regardless of what state divorce law says. In practice, this means if you don’t personally update the beneficiary form on your 401(k) after divorce, your ex-spouse can still receive the funds, even though Idaho’s statute would try to prevent it for other types of assets. 

Life insurance and IRAs deserve the same caution. Insurers and account custodians don’t always check state law before paying out — they often simply pay whoever is listed as beneficiary on file. Relying on the statute to catch an outdated form can mean a real delay, or a real fight, even if you’re ultimately in the right. 

Powers of attorney can be a gap too. If your ex-spouse was named as your agent, an outdated document on file can still create confusion for medical providers or institutions acting in good faith before anyone catches the error. 

Trusts you created together require separate attention. A joint revocable trust, or a trust naming your former spouse as co-trustee or beneficiary, often needs to be restructured entirely — this isn’t something the revocation statute automatically untangles cleanly, especially with jointly titled assets. 

What to Actually Do 

Treat Idaho’s automatic revocation statute as a backstop, not a plan. As soon as a divorce is finalized: 

• Update the beneficiary designations on every retirement account, life insurance policy, and payable-on-death account directly with the institution. 

• Execute a new will, and new financial and healthcare powers of attorney, naming new agents and beneficiaries. 

• Revisit any trust that named your former spouse in any role. 

• Update the guardianship nomination for minor children if it named your former spouse’s family members as alternates. 

• Idaho law provides a meaningful safety net, but it wasn’t designed to be your only plan. A short conversation with your attorney after a divorce is finalized can close the gaps the statute doesn’t reach.
