Beneficiary forms override your will. This is one of the most vital things to know about estate planning. It catches many families off guard. Retirement accounts like 401(k)s, IRAs, and pensions pass by beneficiary form, not by your will or trust. Life insurance, annuities, and payable-on-death bank accounts work the same way. The person listed on the account form gets the funds. It does not matter what your will or trust says.
Why Beneficiary Forms Take Priority
Under both federal and Arizona law, a beneficiary form on a financial account is a contract between you and the company. When you name someone on your 401(k) or life insurance policy, you give a direct order to the company holding those funds. That order beats anything in your will or trust.
Here is what this means in practice. Say your will says "everything goes to my children equally." But your ex-spouse is still on your IRA form. Your ex-spouse gets the IRA. Your children have very few legal options to fight this. Courts have upheld beneficiary forms even when they clearly clash with other estate planning papers.
Accounts That Pass by Beneficiary Form
These accounts skip your will and probate. They go straight to the named person on the form:
- 401(k) and 403(b) retirement plans
- Traditional and Roth IRAs
- Pensions and annuities
- Life insurance policies
- Payable-on-death (POD) bank accounts
- Transfer-on-death (TOD) investment and brokerage accounts
- Health savings accounts (HSAs)
Each of these accounts has its own form that you filled out when you opened it. If you have not checked those forms lately, they may still reflect choices you made years ago.
Common Mistakes That Cause Problems
These are the errors we see most often:
- Ex-spouse still listed. Arizona law does not always void a former spouse's claim on every type of account. ERISA (a federal law) governs employer plans like 401(k)s. Federal law does not remove an ex-spouse on its own. If your former spouse is still on your 401(k), they may inherit no matter what.
- A deceased person still listed. If your named person has passed and you did not update the form, the funds may go to a backup person you did not intend. Or they may default to your estate and go through probate.
- No one named. If the beneficiary line is blank or says "estate," the account goes through probate. That adds cost and delay.
- Forms clash with your trust. Your trust may spell out a detailed payout plan. But if accounts are not titled in the trust or do not name the trust, those assets follow the form instead.
How to Line Up Beneficiary Forms With Your Estate Plan
The names on your beneficiary forms outrank your will and even your trust. Your will only governs assets that do not have a living named person or other transfer method. Your trust only controls assets titled in the trust or that name the trust.
One approach that makes things simpler: name your trust as the beneficiary on accounts where it makes sense. This way, changes to your payout plan only need to happen in one place, your trust, rather than across dozens of forms. But naming a trust on a retirement account has specific tax effects. Talk to your attorney about this. For a deeper look, read our article on whether your trust should be the beneficiary of your IRA or 401(k).
Here is a simple way to get your forms in order:
- List every account that has a beneficiary form
- Ask each company for a copy of the current form
- Compare each form to your will and trust
- Update any forms that do not match your current wishes
- Keep copies of all updated forms in your estate planning binder
When to Review Your Beneficiary Forms
Review your forms whenever you go through a major life change. This includes marriage, divorce, the birth of a child, the death of a named person, or retirement. At minimum, check them once a year during your yearly estate plan review.
If you have not looked at your beneficiary forms in the last few years, that is a simple but strong place to start. Your estate planning attorney can help you audit all of your accounts. Together you can make sure the right people, or your trust, are named.
