You can have a perfectly drafted will and still have your largest assets pass to the wrong person. Here’s the trap that catches even careful, organized people.
The scenario. Tom, 48, divorced his first wife, Karen, and later remarried. He updated his will to leave everything to his new wife, Sofia — exactly what he thought he was supposed to do. But he never changed the beneficiary designation on his $480,000 401(k), which still named Karen. When Tom died unexpectedly, the 401(k) passed to Karen, his ex-wife, regardless of what his will said. Sofia’s only options were expensive, uncertain litigation.
The problems.
- An outdated beneficiary designation sent the largest single asset to an ex-spouse.
- The will could not — and legally cannot — override the 401(k) beneficiary form.
- The intended heir was left to consider costly, uncertain litigation.
The planning solution.
The core principle: beneficiary designations are non-probate transfers that pass outside your will and override it. Retirement accounts (401(k)s, IRAs, 403(b)s), life insurance, annuities, and any payable-on-death (POD) or transfer-on-death (TOD) account all pass by designation, not by will. If the form is wrong, the rest of your plan barely matters for that asset.
The practical fix is a comprehensive beneficiary audit. Pull every account and policy and confirm both the primary and the contingent (backup) beneficiary on each. Missing contingent beneficiaries are a common, costly oversight — if your only named beneficiary predeceases you, the asset can default to your estate and into probate.
Then update after every major life event: divorce, remarriage, the birth or adoption of a child, or the death of a named beneficiary. A worthwhile nuance: under federal ERISA rules, most employer-sponsored plans require your current spouse to be the beneficiary unless they consent in writing to someone else — another reason to review forms after any marriage or divorce. (Note that divorce does not always automatically remove an ex-spouse from a beneficiary form, especially on ERISA plans — you generally must change it yourself.)
Finally, coordinate the designations with your will and trust so every asset points in the same intended direction. Treat beneficiary forms as a core part of your estate plan, not an afterthought handled years ago at account opening.
Key takeaways.
- Beneficiary forms override your will; coordinate them deliberately.
- Confirm primary AND contingent beneficiaries on every account.
- Update forms after divorce, remarriage, births, and deaths.
