What happens to a 401(k) if it still names an ex-spouse as beneficiary?

✓ Accepted answer

If a 401(k) still names an ex-spouse as the primary beneficiary, that former spouse is typically entitled to receive the funds, overriding any contrary provisions in your current will.

• Automatic revocation statutes: In many US states and the UK, divorce does not automatically remove a former spouse from 401(k) beneficiary forms. The account will generally be paid to the ex-spouse unless you have formally updated the designation on the plan administrator's specific form.
• Plan documents control: The participant agreement of your 401(k) plan dictates the rules. Most plans prioritize the beneficiary form over a will or trust, meaning a will cannot legally redirect the retirement assets to a new beneficiary.
• Update the paperwork: To prevent unintended inheritance, you must submit a new beneficiary designation form directly to the plan provider or financial institution holding the account. This is a legal document that supersedes all other estate planning tools for that specific asset.
• Check for contingent beneficiaries: If the ex-spouse is listed as a contingent beneficiary only, the funds will pass to your primary beneficiary (such as a current spouse or trust). However, relying on secondary designations is risky if the primary status is not clearly updated.
• Review after major life events: Financial advisors recommend reviewing retirement account beneficiaries annually. This ensures your estate plan reflects your current wishes and prevents legal disputes that can delay asset distribution for months.
