Question:
❓ Who actually inherits your 401(k) — the person named in your will, or the beneficiary form on the account?
A) The beneficiary form on the account.
B) Whoever’s named in your will — the will is the final word.
C) It’s split equally among your surviving children.
D) It goes into your estate and is distributed through probate.
✅ Answer: A)
The beneficiary form on the account.
Here’s why:
A will does not override your 401(k) beneficiary form. Whoever is named on the beneficiary form filed with your 401(k) inherits the account, no matter what your will says. That form controls the money directly, and the account passes outside of probate.
Your will governs a lot of things, but your 401(k) isn’t one of them. The beneficiary form you filled out when you opened the account decides who gets it—often a form you signed on your first day at a job and never looked at again.
Here’s how the two actually compare:
| Your will | Your 401(k) beneficiary form | |
|---|---|---|
| Controls your 401(k)? | No | Yes |
| Controls your house and belongings? | Yes | No |
| Goes through probate? | Yes | No—pays out directly |
| Can it be overridden by the other? | Yes—the form wins | No—it overrides the will |
| How fast does it pay out? | Months, after probate | Usually weeks, straight to the person named |
401(k)s come with an extra rule of their own: federal law makes your current spouse the automatic beneficiary. To name anyone else—even your own kids—your spouse has to sign a written, notarized waiver giving up that right.
The bigger danger is an outdated form. The classic case: someone gets divorced, updates their will, gets on with life, and never changes the 401(k) form still naming their ex. When they die, the ex inherits the whole account. One version of this went all the way to the U.S. Supreme Court—and the ex still won, because even a divorce decree where she’d given up any claim didn’t beat the form on file.
Why the others are not correct:
B) Whoever’s named in your will. The will feels like the final word, and for your house, car, and belongings it usually is. Retirement accounts with a named beneficiary are the exception—they pay out on their own, no matter what the will says.
C) Split equally among your children. An even split among your kids only happens if you actually name them that way on the form. Left alone, the account goes wherever the form points—which might be one child, an ex, or someone else.
D) Distributed through probate. Probate only comes into play when no valid beneficiary is on file. As long as a living person is named, the account skips probate and pays out directly to them.
Takeaway:
Your 401(k) goes to whoever is on the beneficiary form. Update that form after every marriage, divorce, or new baby—your will won’t do it for you.
