The form beats the will
A retirement account, a life-insurance policy, and an annuity all pass by beneficiary designation — a contract term telling the custodian who receives the asset at death. That designation controls regardless of what your will says. Courts have enforced this even where the result is plainly not what the deceased would have wanted: the U.S. Supreme Court held that a plan administrator must pay the beneficiary named in the plan documents, even an ex-spouse the participant had divorced, because the plan’s designation governs (Kennedy v. Plan Administrator for DuPont Savings & Investment Plan, 555 U.S. 285 (2009)). Your will cannot override a beneficiary form; only a new form can.
The mistakes that surface too late
These errors share a cruel trait: nothing reveals them until the owner has died and they can no longer be fixed.
- The stale designation. An ex-spouse, an estranged relative, or a person who has since died, still named. Some states revoke an ex-spouse designation automatically, but the rule varies and does not always apply to federally governed (ERISA) plans — do not rely on it.
- No contingent beneficiary. If the sole primary beneficiary has died and no backup is named, the account may fall to the plan’s default — often the estate — losing the ability to name a designated beneficiary and, with it, favorable payout options.
- Naming the estate. Naming your estate (or letting it default there) generally means there is no “designated beneficiary,” which can force a faster, less favorable payout and drag the account through probate.
- Naming a minor outright. A minor cannot legally control an inherited account; without a properly structured arrangement, a court-supervised guardianship may be required. Minors need a deliberate structure, not a bare designation.
- Forms that fight the plan. A retirement-account designation, a will, and a trust that each say something different about the same wishes create conflict the family untangles later. Consistency across all of them is the goal.
Primary and contingent, and keeping copies
Every account should name both a primary beneficiary and at least one contingent (backup) beneficiary, and you should keep a copy of each confirmed form. Custodians occasionally lose or mis-record designations; a confirmed copy in your records is the proof your family may need. Naming a trust as beneficiary is sometimes the right move — for a minor, a person with special needs, or for control — but it interacts with the 10-year rule and should be done with advice, not on the account form alone.
The beneficiary-audit checklist
Print this and work through every account that passes by designation. It collects nothing — it is a worksheet, not a form.
Beneficiary-designation audit
- List every account with a beneficiary form: each IRA, 401(k), 403(b), pension, life-insurance policy, and annuity.
- For each, confirm the primary beneficiary is current and intended.
- For each, confirm a contingent beneficiary is named.
- Check for anyone named who has died, divorced out of the family, or is estranged.
- Confirm no account defaults to “my estate” unless that is deliberate and advised.
- For any minor beneficiary, confirm a proper structure (not a bare designation) is in place.
- Check that the designations are consistent with your will and trust.
- Obtain and file a written confirmation of each designation from the custodian.
- Re-run this audit after every marriage, divorce, birth, or death in the family.

The controlling-designation principle is illustrated by Kennedy v. Plan Administrator for DuPont Savings & Investment Plan, 555 U.S. 285 (2009), linked to the opinion. State revocation-on-divorce statutes and their interaction with ERISA-governed plans vary; treat automatic revocation as unreliable and update forms directly. See our editorial standards.
