Your will says your current spouse gets everything. Your 401(k) says your ex-spouse gets $400,000. Your ex-spouse gets $400,000.
That is not a hypothetical edge case. The beneficiary form you filled out in ten minutes during onboarding — or during the bleary first week after launching your business — legally overrides whatever your will says about that account. Wills govern assets that pass through probate. Beneficiary designations bypass probate entirely, which means they also bypass your will. When the two conflict, the designation wins, every time.
This matters more for business owners than for anyone else, because you have more accounts than anyone else: a Solo 401(k) or SEP IRA, maybe an old employer 401(k) still sitting at a former custodian, business and personal life insurance (possibly tied to a buy-sell agreement), business bank accounts, an HSA, possibly annuities. Each one carries its own form, its own primary and contingent beneficiaries, and its own opportunity to send money to the wrong person. This post walks through the account-by-account audit that closes those gaps.
Why the Form Beats the Will
When you open a retirement account, buy life insurance, or add a payable-on-death registration to a bank account, you sign a contract with the custodian. That contract says: when I die, pay this account to the person named here. Courts treat that as a binding instruction that operates independently of your estate plan.
The practical consequences cut three ways:
Speed. Assets with valid beneficiary designations typically transfer in weeks, directly from custodian to beneficiary, with no court involvement. Assets without one — titled in your name alone — go through probate, a months- or years-long process during which a court validates the will and settles debts, taxes, and fees first. Fidelity notes that probate costs commonly total 2% to 5% of the assets passing through it. A designation is the cheapest probate-avoidance tool you own.
Certainty. A designation names a person. Probate invites interpretation — and disagreement among surviving family members about what you intended. The form leaves no room for argument.
Risk. Because the designation wins conflicts silently, an outdated form is worse than no estate plan at all: it creates the illusion of a plan while directing money somewhere you no longer want it to go. Fewer than one in four Americans even has an estate plan, according to Caring.com's 2025 wills study — and among those who do, stale beneficiary forms are one of the most common ways the plan fails in practice.
The Account-by-Account Audit
Set aside an hour, log in to every custodian, and check each account below. For each one, confirm three things: a primary beneficiary is named, a contingent (backup) beneficiary is named, and both names still reflect your wishes.
1. Retirement accounts: Solo 401(k), SEP IRA, traditional and Roth IRAs
These are usually your largest beneficiary-designated assets, and the rules around them are the strictest.
- Employer-plan spousal rights carry over. In a traditional employer 401(k) governed by ERISA, your spouse is automatically the beneficiary unless they sign a written waiver consenting to someone else. Solo 401(k)s have more flexibility, but many plan documents still default to the spouse. If you are married and want a non-spouse primary beneficiary on any 401(k), verify the plan's spousal-consent rules before assuming the form you filed controls.
- IRAs follow state law. In community-property states, naming someone other than your spouse as an IRA beneficiary may require your spouse's written consent. In common-law states you generally have more freedom — but check your state's rules rather than assuming.
- Old employer plans count. That 401(k) from the job you left six years ago has its own beneficiary form, still on file with the old custodian. It does not sync with anything. Either roll it over (which lets you set fresh designations) or log in and update it where it sits.
- Remember the tax character. Whoever inherits a pre-tax account pays income tax on withdrawals, and most non-spouse beneficiaries must empty an inherited IRA or 401(k) within 10 years under the SECURE Act. A Roth account passes income-tax-free. That difference can reasonably change who you name on which account — for example, leaving pre-tax accounts to a spouse in a lower bracket and Roth accounts to children. Coordinate the designations with the tax picture, not in isolation.
2. Life insurance: personal, business, and buy-sell policies
Business owners often carry three overlapping layers of coverage, each with its own beneficiary — and each serving a different purpose.
- Personal policies protect your family. Name individuals (or a trust, discussed below), not "my estate" — naming your estate routes the payout through probate and exposes it to creditor claims in many states, defeating the point of the designation.
- Key-person policies are owned by the business to cushion the loss of someone critical. The beneficiary should be the business itself. If you personally are the insured key person, make sure the business — not your family — is the beneficiary, or the company you built gets no protection from the policy it paid for.
- Buy-sell funding policies exist so surviving partners can buy out a deceased owner's share. The beneficiary structure must match the agreement: in a cross-purchase arrangement each owner typically owns policies on the others; in an entity-purchase (redemption) arrangement the business owns them. A buy-sell agreement rewritten five years ago with insurance beneficiaries never updated to match is a lawsuit waiting for a funeral. Review the agreement and the policies side by side.
Also check employer-provided group life from any W-2 job (current or former) and any policy held inside a trust — trust-owned policies should name the trust, and the trust document then controls distribution.
3. Bank accounts: payable on death (POD)
Most banks let you add a POD registration so the account passes directly to a named person. This is worth doing on both personal and business accounts — a sole proprietor's business checking account with no POD designation and no surviving joint owner can freeze at death, leaving bills unpaid and employees in limbo while the estate sorts itself out.
POD designations cost nothing, take minutes at the branch or online, and do not give the beneficiary any access while you are alive. There is no reason a sole-proprietor business account should lack one.
4. Brokerage accounts: transfer on death (TOD)
Taxable brokerage accounts work the same way through TOD registration: name the beneficiaries, and the account transfers outside probate. If you hold business reserves or a personal portfolio in a taxable account with no TOD and no joint owner, add one.
One caution: TOD registrations and joint ownership interact. If the account is jointly owned with right of survivorship, the surviving joint owner takes the whole account regardless of the TOD form. Make sure the titling and the designation tell the same story.
5. HSAs and annuities
- HSAs accept beneficiary designations, and the tax treatment makes the choice matter enormously: a spouse beneficiary can treat your HSA as their own and keep the triple tax advantage, while a non-spouse beneficiary generally receives the balance as taxable income in the year of your death. If your HSA has grown into a real asset, the designation deserves the same attention as your IRA's.
- Annuity contracts have their own beneficiary provisions, sometimes with options (lump sum vs. continued payments) that beneficiaries must elect. Confirm the named beneficiary and make sure your family knows the contract exists — an annuity nobody knows about pays nobody.
6. 529 plans and business interests
A 529 account has an owner (you) and a beneficiary (the student), plus a successor owner you should name so control of the account — not just its funds — passes smoothly. And while operating agreements and buy-sell provisions (not beneficiary forms) usually govern what happens to your ownership stake, confirm the agreement actually addresses death: who can buy, at what price, funded how. An ownership interest with no transfer plan is the business equivalent of an account with no beneficiary.
Five Designation Mistakes That Undo Estate Plans
As you audit, watch for these specific failure modes:
1. No contingent beneficiary. If your primary beneficiary dies before you — or at the same time — and the contingent line is blank, the account typically reverts to your estate and goes through probate. Always name at least one backup. This single blank line is probably the most common beneficiary-designation defect in existence.
2. No per stirpes instruction. Suppose you name your three children as equal beneficiaries, and one of them dies before you, leaving kids of their own. Without a per stirpes designation, the deceased child's share is usually redistributed among your surviving children — your grandchildren from that child get nothing. With per stirpes, the deceased child's share passes to their descendants. Not every custodian offers the option on every form, so check the actual form language; where it is available and matches your intent, elect it explicitly.
3. Minor children named directly. Children under 18 (19 or 21 in some states) cannot take title to retirement accounts or insurance proceeds in their own names. Name a minor directly and a court must appoint a guardian or conservator to manage the money until adulthood — an expensive, supervised process. The standard fix is naming a trust for the child's benefit, with a trustee and distribution terms you choose. A related trap: naming a custodian under UTMA/UGMA works for some assets but generally cannot receive IRA or 401(k) proceeds properly.
4. A special-needs beneficiary named directly. An outright inheritance can disqualify someone from means-tested government benefits. Families in this situation typically route the inheritance through a special-needs trust instead. This is genuinely attorney territory — the rules are state-specific and the cost of error is someone's benefits.
5. Relying on divorce to fix stale forms. Divorce decrees generally do not rewrite beneficiary designations. You must file new forms with each custodian after the divorce is final. Some states have laws auto-revoking ex-spouse designations, but federal law preempts those statutes for ERISA-governed employer plans — meaning the auto-revoke you are counting on may not apply to your largest account. Never rely on it. After a divorce, re-file every form: retirement accounts at every custodian, every life insurance policy, POD and TOD registrations, the HSA, annuities. Treat it as a checklist, not an assumption.
Build the Review Habit
Beneficiary designations are not set-and-forget. Review them on two triggers:
- Life events, immediately: marriage, divorce, birth or adoption of a child, death of a named beneficiary, a new business entity or buy-sell agreement, a move to or from a community-property state, a major change in an account's value.
- Calendar, every two to three years: even with no life changes, custodians merge, plan documents get restated, and state law moves. A brief review on a fixed schedule catches drift.
Make the audit repeatable by keeping a one-page beneficiary inventory alongside your financial records: every account, its custodian, the primary and contingent beneficiaries named, the date last verified, and where the confirmation lives. Store it with your will and operating agreements — not in your head — and tell your executor where to find it. The inventory turns a dreaded project into a fifteen-minute check, because next time you are verifying rather than discovering.
One caution on that inventory: it is a roadmap to your accounts. Keep it somewhere secure — with your estate-planning documents, not in an unlabeled spreadsheet on a shared drive.
Keep Your Financial Records Organized
A beneficiary audit is really a recordkeeping project: scattered accounts, forgotten forms, and outdated instructions are all failures of financial organization, not of intent. The owners who complete the audit in an hour are the ones who already know where every account lives and can pull up any form on demand.
