You can pay a lawyer to draft a perfect will and still send money to the wrong person. The reason surprises most people: beneficiary designations on your retirement accounts and life insurance override whatever your will says. A quick audit is one of the highest-value, lowest-effort moves in personal finance, and 2026 is a good year to do it.
Why beneficiary forms trump your will
When you open a 401(k), IRA, or life insurance policy, you name a beneficiary. At death, those assets pass directly to whoever is listed, bypassing your will and the probate process entirely. If your will leaves everything to your current spouse but an old 401(k) still names an ex, the ex inherits. The will does not fix it. This is why stale designations cause some of the most painful and avoidable inheritance disputes.
Accounts that use beneficiary designations
- Retirement accounts: 401(k), 403(b), traditional and Roth IRAs.
- Life insurance: both employer-provided and individual policies.
- Bank and brokerage accounts: via payable-on-death or transfer-on-death designations.
- Annuities and HSAs: which also pass by named beneficiary.
The 10-year rule that reshapes inheritance
Naming the right person is only half the job; how they inherit matters too. Under current rules, most non-spouse beneficiaries must fully distribute an inherited IRA within 10 years. That can force a large taxable withdrawal into your heir's peak earning years. Knowing this lets you plan, perhaps by doing Roth conversions during your lifetime so heirs inherit tax-free dollars instead.
Do not forget contingent beneficiaries
- Primary beneficiary: the first person in line to inherit.
- Contingent beneficiary: who inherits if the primary has already died.
- Why it matters: without a contingent, assets can fall back into probate, the very outcome designations are meant to avoid.
Do not overlook digital assets
Modern estates include online accounts, cryptocurrency, and other digital property that traditional forms never contemplated. Make sure your plan includes instructions and access provisions for these, since a crypto wallet with no recovery plan can be lost forever regardless of what any beneficiary form says.
Your 15-minute audit checklist
- Log into every retirement, insurance, and brokerage account and read the named beneficiary.
- Update anything naming an ex-spouse, a deceased relative, or no one at all.
- Add contingent beneficiaries wherever they are missing.
- Confirm minor children are not named directly, which can trigger court oversight.
- Document digital assets and how a trusted person can access them.
- Repeat the review after any marriage, divorce, birth, or death in the family.
Bottom line
Beneficiary designations are the silent controllers of a large share of most people's wealth, and they are astonishingly easy to neglect. A short annual review ensures your money goes exactly where you intend, spares your family a legal fight, and coordinates with the tax rules that govern inherited accounts. Few financial tasks deliver this much protection for so little time.
