A man dies with a valid will leaving everything to his brother. His 401(k) pays his ex-wife. The will was drafted correctly. The lawyer did nothing wrong. The money went to the ex-wife anyway, because a form he filled out at a job years earlier had her name on it, and he never changed it.
That is not a glitch. It is how the system is built, and it happens constantly.
The Form Wins, Not the Will
A beneficiary is the person named to receive an account when the owner dies. Retirement accounts, life insurance policies and payable-on-death bank accounts each have their own form, and each pays whoever is on it.
Your will does not reach them. If your will says one thing and the form says another, the form pays out and the will never enters the conversation.
Why the Form Wins
These accounts are contracts. Part of the agreement names who gets paid. When you die, the institution reads its own document, pays that person, and closes the file. Your will is not part of that contract, so nobody reads it.
Federal law makes this even harder to escape at work. Many states have a law that cancels an ex-spouse's rights automatically the moment a divorce is final. In Egelhoff v. Egelhoff (2001), the Supreme Court held that ERISA, the federal law covering employer retirement and benefit plans, overrides those state laws. The ex-wife kept the pension and the life insurance.
It goes further. In Kennedy v. Plan Administrator for DuPont (2009), an ex-wife had already signed away her rights in the divorce decree. The plan paid her anyway, and the Supreme Court unanimously agreed it had to, because the form still named her and administrators follow the plan documents.
Both rulings stop at ERISA's edge, and ERISA covers employer plans only. Outside it, those state laws do work: on IRAs, on life insurance you bought yourself rather than through work, and on payable-on-death or transfer-on-death accounts at a bank or brokerage. About half the states have such a law, modeled on the Uniform Probate Code, so a divorce there can cancel an ex-spouse's name by itself. Do not lean on that. A rule that reaches some of your accounts in some states is no substitute for a current form.
There is an upside. An asset with a valid designation skips probate, the slow public court process that supervises a will. Money that passes by contract often reaches the person in weeks.
Where Your Forms Are Hiding
Go count yours. Workplace plans, including a 401(k), 403(b) or 457. Every IRA, traditional and Roth. Health savings accounts. Life insurance, including the policy from work you forgot about. Pensions and annuities.
Two more are easy to miss. A brokerage account can carry a transfer-on-death registration and a bank account a payable-on-death designation. Neither exists unless you asked for it, and an account without one goes into your estate.
Primary and Contingent
The primary beneficiary gets the money. The contingent beneficiary gets it only if every primary has already died.
Most people fill in the primary and skip the contingent. If your primary dies first and there is no backup name, the money falls to the plan's default order or to your estate, the outcome the form existed to prevent. Adding a contingent takes one line.
The Four Failures That Actually Happen
The ex-spouse is still named. This is the most common one by a wide margin, because divorce paperwork and benefits paperwork are handled by different people who never speak.
A minor child is named directly. No plan or insurer hands a check to an eight-year-old. A court appoints someone to manage it, which costs time and legal fees, and in most states the child takes full control at 18 or 21.
The estate is named. Now the asset goes through probate, sits exposed to creditors, and loses ground on taxes. An estate is not a person, so a retirement account left to one cannot use the slower payout schedule an individual beneficiary would get.
The form is blank or missing. The plan's own default order decides, and you may never have read it.
One more thing about that payout schedule. Under the SECURE Act, most non-spouse beneficiaries have to empty an inherited retirement account within ten years of the owner's death. The old lifetime stretch is gone for them. A surviving spouse has better options, including rolling the account into their own, and a minor child of the owner or a disabled beneficiary is treated differently again.
Your Spouse Might Already Be Named
For most employer retirement plans, federal law makes your spouse the default beneficiary. Naming anyone else, including your own children, requires your spouse's written consent, witnessed by a notary public or a plan representative. Your signature alone does nothing.
That rule comes with private-sector plans. Government and church employers sit outside ERISA, and many 403(b) and 457 plans belong to school districts, cities and churches. If you teach or work for the county, check your own plan's rules rather than assume.
IRAs work differently. There is no federal spousal consent requirement, so whoever you name is usually who gets paid. In community property states a spouse may still have a claim to part of what was earned during the marriage.
What to Do This Week
Six things should send you back to these forms: marriage, divorce, a birth or adoption, a death in the family, changing jobs, and your employer switching plan providers. That last one catches people, because designations sometimes fail to transfer and nobody tells you.
Log into each account today. Find the beneficiary section, usually under profile or settings rather than investments. Read what is there instead of what you remember entering. Screenshot it with the date visible. Then keep one list, somewhere your family can find it, of every account and who is named.
Some situations need a lawyer rather than a web form. If a beneficiary receives means-tested benefits such as Medicaid or SSI, money paid straight to them can cost those benefits, and a trust named on the form is the usual fix. Blended families, minor children and large estates are the other three. Even then the form controls, so point it at something built on purpose instead of a name you typed in a hurry.
