When did you last look at the beneficiary on your 401(k)?
If the answer is “when I started the job” — that form is still your estate plan for that account. Not your Will. Not your intentions. That old form, exactly as you filled it out.
Why Beneficiary Designations Override Your Last Will
Life insurance policies, retirement accounts, IRAs and 401(k)s, payable-on-death bank accounts: these assets are designed to move outside your will entirely. They go directly to whoever is listed on the beneficiary form the moment you die.
It doesn’t matter what your Will says. The form is the instruction. And it goes exactly where it points.
This is not a flaw in the system. It is how the system is built. But it catches people off guard constantly, including people who believed they had planned carefully.
The Triggers Nobody Thinks About
Beneficiary forms go stale quietly, over time.
A job change years ago. You set up the new 401(k), filled out the form, moved on. A refinance to get a better rate. An account set up during a different chapter of your life. These feel like administrative tasks. Nobody flags them as estate planning decisions.
But a retirement account or life insurance policy set up during a job change years ago, if you meant to update it and life moved on, it still says what it said the day you filled it out.

If your family situation has changed — a remarriage, stepchildren, a new chapter — outdated forms carry more risk. Here is what blended families need to think through.
What to Do About It
Pull your beneficiary designations. All of them. Check who is listed on each one. Then ask one honest question: does this still reflect what I want?
Life insurance. Retirement accounts. Any account with a named beneficiary or a payable-on-death designation.
Then ask whether all of those point in the same direction as your Will.
