Beneficiary Designations: The Silent Estate Plan
Your IRA, 401(k), and life insurance don't care what your will says. Here's how to keep the form on file from undoing your entire estate plan.
Your IRA, 401(k), and life insurance don't care what your will says. Here's how to keep the form on file from undoing your entire estate plan.
Why the form wins
IRAs, 401(k)s, life insurance, annuities, and TOD/POD accounts pass by contract — not by will, not by trust (unless the trust is specifically named). Whatever's on the form is what happens. Period. You can spend $6,000 on a beautiful estate plan and still have your 401(k) go to your ex-spouse from 1998 because nobody ever pulled the form.
The classic disaster
Ex-spouse still on the 401(k) form. Deceased parent still listed. The estate listed as beneficiary (which forces a 5-year IRA payout and higher taxes for heirs). One old form can undo a $5,000 estate plan.
Primary vs contingent
Primary receives if alive. Contingent receives if primary is not. Missing contingents is the most common gap — and when it costs the most.
Per stirpes vs per capita
If a beneficiary predeceases you, 'per stirpes' passes their share to their children. 'Per capita' redistributes among surviving beneficiaries. Pick deliberately — most people never do.
Should I name my trust as beneficiary?
Sometimes — usually when children are minors, have special needs, or you want distribution control. It's more complex and can affect the payout stretch. Do it with an estate attorney, not from a website form.
What's the 10-year rule?
Non-spouse beneficiaries of IRAs (post-2019) must generally empty the inherited account within 10 years. Certain 'eligible designated beneficiaries' (spouse, minor child, disabled, chronically ill) can still stretch over life expectancy.
Never name a minor without a custodian
A minor can't legally receive the money directly. Without a trust or custodian named, the court appoints one — slow, public, and expensive.
The audit worksheet
Every 3 years — or after every marriage, divorce, birth, death, or job change — pull up: Traditional IRA · Roth IRA · 401(k)/403(b) · pension survivor election · life insurance (personal AND employer group) · HSA · brokerage TOD/POD · checking/savings POD. For each: Custodian / Primary / Contingent / Date Verified. Copy stored where: ______.
The ex-wife on the 401(k)
Gary divorced Linda in 2002 and remarried Diane in 2005. When Gary died in 2024, his will left everything to Diane, his trust was funded, his IRA correctly named Diane — but his 401(k), a rollover from age 27, still named Linda from 1998. By federal ERISA law the plan administrator paid the named beneficiary: Linda got $410,000. Diane got nothing. In some states an ex-spouse designation is auto-revoked at divorce; ERISA 401(k)s are federal, and state auto-revocation doesn't apply.
The day a divorce is final, walk to HR and update every beneficiary form. Then verify again a year later. If a form hasn't been reviewed in three years, treat it as wrong until proven right.
