“We have a will, so we’re covered.” We hear some version of that in a lot of first meetings, and it’s said with real relief. Getting a will signed is a meaningful step, and if you’ve done it, you’ve done more than most people.
Here’s what often surprises families: a will controls far less than they think. It doesn’t decide who receives your 401(k) or your life insurance. It doesn’t override the way your house or your bank accounts are titled. And it does nothing at all if you’re alive but unable to make decisions. These estate planning blind spots tend to stay hidden until the moment the plan is tested, which is exactly when your family can least afford a surprise.
And sometimes the will itself isn’t what the family thinks it is. Before we get to the four blind spots, that’s worth a quick check.
This guide walks through the four gaps we see most often and ends with a mini-audit checklist you can complete in about 20 minutes with your documents in front of you.
Before the four blind spots
Is your will actually signed?
It happens more often than you’d expect. A family meets with an attorney, reviews the draft, means to come back to sign it, and life gets in the way. Years later, the will in the file drawer is an unsigned draft, and everyone believes it’s done.
In Arizona, a typed will generally must be signed by you and by two witnesses to be valid. A will entirely in your own handwriting and signed by you can also qualify.[11] Notarization isn’t required, but a self-proving affidavit signed with a notary can make probate smoother.
An unsigned will generally carries no legal weight. Your estate is handled as if you had no will at all: Arizona’s intestacy law decides who inherits,[12] the court decides who administers the estate, and any wishes you wrote down, such as who should raise your children, may not be followed. Take a minute to find your original and look at the signature page.
The Short Version
A will is one piece of the plan
Most of what you own may pass outside your will entirely, through beneficiary forms and account titling. A complete plan coordinates all of it and also covers the years when you might need someone to act for you.
- Beneficiary formsGenerally override your will
- Joint & TOD titlingPasses outside your will
- IncapacityA will has no authority while you’re living
- Review rhythmEvery 3–5 years or after a life event
Key takeaways
- Start with the basics: a will that was drafted but never signed and witnessed generally has no legal effect.
- Retirement accounts, life insurance and annuities pass to whoever is named on the beneficiary form, even if your will says something different.
- Joint ownership, transfer-on-death registrations and Arizona beneficiary deeds also move assets outside your will, and a trust only controls the assets actually titled to it.
- A will only speaks at death. Without durable and health care powers of attorney, your family may need a court to act for you if you become incapacitated.
- Plans go stale. Divorce, remarriage, grown children, a move or a change in tax law can quietly turn a good plan into the wrong one.
- The fix is usually paperwork, not a crisis. A short, regular review catches most of these gaps while they’re still easy to correct.
Blind spot 1: Beneficiary designations that override your will
For many households, the largest assets aren’t the house or the checking account. They’re the 401(k), the IRA, the life insurance policy and perhaps an annuity. Every one of those passes by contract, not by will. When you die, the plan administrator or insurance company pays whoever is named on the beneficiary form on file. Your will isn’t consulted.
The U.S. Supreme Court made this point sharply in Kennedy v. Plan Administrator for DuPont. A former wife had waived her interest in her ex-husband’s retirement plan in their divorce decree, but he never changed the beneficiary form. The Court held the plan was right to pay her, because the plan documents and the form controlled.[1]
Arizona law automatically revokes many beneficiary designations in favor of a former spouse after divorce,[2] but that protection generally doesn’t reach employer plans governed by federal law, such as most 401(k)s and group life insurance.[3] The form is what counts.
Where beneficiary designations go wrong
An ex-spouse or a deceased person is still named. Forms are often completed once, at hire or at purchase, and never revisited.
No contingent beneficiary. If the primary beneficiary dies first and there’s no backup, the account may default to your estate and go through probate.
Your estate is named as beneficiary. That pulls an asset that could have passed directly back into probate. For an inherited IRA, it can also shorten the time your heirs have to withdraw the money, which can raise the tax cost.[4]
A minor child is named outright. Insurance companies and custodians generally won’t pay a large sum directly to a minor, so a court-supervised arrangement may be needed until the child reaches adulthood, and the child may then receive everything at once. Naming a trust or a custodian for the child usually works better.
The form doesn’t match the plan. If your will or trust divides everything equally among three children but your IRA names only one, the IRA follows the form.
One more detail for married savers: most 401(k) and other employer plans require your spouse to be the beneficiary unless your spouse signs a written waiver,[5] and in a community property state like Arizona, naming someone other than your spouse on an account built with marital earnings can raise questions of its own. Those rules are worth working through with your attorney.
Blind spot 2: Asset titling that works against your plan
Titling is how an asset is legally owned, and it often decides where the asset goes before your will is ever read. Here’s a quick map of what typically controls each type of asset:
| Asset or ownership type | What usually decides who receives it | Does your will control it? |
|---|---|---|
| 401(k), IRA, 403(b) | Beneficiary designation | No |
| Life insurance, annuities | Beneficiary designation | No, unless your estate is named |
| Bank or brokerage account with POD or TOD | The named payable-on-death or transfer-on-death beneficiary | No |
| Joint tenancy or community property with right of survivorship | The surviving owner | No |
| Home with a recorded Arizona beneficiary deed | The beneficiary named on the deed | No |
| Assets titled to your revocable trust | The terms of your trust | No, the trust controls |
| Assets in your name alone, with no beneficiary | Your will, through probate | Yes |
General illustration only. How a specific asset passes depends on its documents, how it’s titled and state law.
Arizona beneficiary deeds are authorized under A.R.S. § 33-405.[6]
Three titling problems come up again and again.
The unfunded trust. Many families pay to create a revocable living trust, sign it, and file it away without ever retitling the house or the accounts into the trust’s name. A trust can only manage what it owns. Anything left in your individual name may still require probate, which defeats much of the reason for having the trust. Accounts opened after the trust was signed are especially easy to miss.
“Convenience” joint accounts with a child. Adding an adult child to an account so they can help pay bills is common, and it can quietly disinherit their siblings, because the joint owner typically keeps the whole account at your death. It can also expose the account to that child’s creditors or divorce.
Property in another state. If you still own a cabin in Colorado or a rental in California in your own name, your family may face a second probate in that state. Titling it to your trust can often prevent that.
The cost of these gaps is rarely dramatic in a single moment. It shows up as months of court process, legal fees, frozen accounts while bills still come due, and occasionally a family conflict that didn’t need to happen.
Blind spot 3: No plan for incapacity
This is the gap most families never think about, because a will is about death. It has no authority while you’re alive. Yet a stroke, an accident or dementia can leave someone unable to manage money or make medical decisions for months or years.
Without the right documents, your spouse or children may not be able to access your accounts, sign your tax return, talk with your doctors or sell the house to fund your care. In Arizona, the alternative is often a court petition to appoint a conservator for your finances or a guardian for personal and medical decisions. That means filing fees, attorney fees, a court hearing, and ongoing reporting to the court. It’s public, it takes time, and the person the court appoints may not be the one you would have chosen.
The core incapacity documents
Durable financial power of attorney. Names someone to manage your finances if you can’t. “Durable” means it stays effective after you become incapacitated.
Health care power of attorney. Names someone to make medical decisions on your behalf.[7]
Living will. Records your wishes about end-of-life care so your family isn’t left guessing.[7]
Mental health care power of attorney. Arizona recognizes a separate document for mental health treatment decisions, which many plans leave out.[8]
HIPAA authorization. Lets the people you choose receive medical information, which they often need before they can step in at all.
A revocable trust also helps here, because a successor trustee can manage trust assets without going to court. And the documents need to be usable: some financial institutions are slow to honor older powers of attorney or ask for their own forms, so it’s worth confirming ahead of time that yours will be accepted. The Arizona Attorney General’s office offers free life care planning forms and guidance as a starting point.[9]
Blind spot 4: A plan written for a family you no longer are
An estate plan is a snapshot of your family and the law on the day you signed it. Both keep changing. Here are the moments that should send you back to your documents:
Family
Marriage, divorce or remarriage
Blended families in particular need deliberate planning so a surviving spouse and children from a prior marriage are each provided for.
Family
Children grow up
The guardian you named for toddlers may not be right for teenagers, and adult children may now be your best choice as executor or trustee.
Money
A sale, an inheritance or a new business
A significant change in assets can change which strategies make sense and whether your fiduciaries are equipped for the job.
Law
Tax law changes
Older trusts drafted for lower estate tax exemptions may divide assets in ways that no longer save tax and can cost heirs a step-up in basis.
That last point deserves attention right now. Federal law enacted in 2025 set the estate and gift tax exemption at $15 million per person for 2026, indexed for inflation going forward.[10] Many plans drafted ten or twenty years ago automatically split assets into separate trusts at the first spouse’s death, a structure built for a very different exemption. For some families those provisions still serve a purpose, such as protecting children from a prior marriage or shielding assets from creditors. For others they now add complexity and income tax cost without an estate tax benefit. It’s a question for your attorney, and an easy one to overlook.
Two other quiet problems: plans that leave everything to children outright at 18, and plans whose named executors or trustees have moved away, become ill or passed away. Neither is unusual, and both are simple to fix while you’re healthy.

Where I’d start this week
Justin Kauffman, CFP®, CEPA®
- Pull the beneficiary forms first. They’re usually the largest assets, the quickest to check and the easiest to fix, often with a single online form.
- Read your trust’s schedule of assets. Then compare it with your statements. The gap between the two is your funding to-do list.
- Have one conversation. Tell the people you’ve named that you’ve named them, and where to find what they’ll need.
Frequently asked questions
Does a beneficiary designation override my will?
Yes, in most cases. Retirement accounts, life insurance, annuities and accounts with payable-on-death or transfer-on-death designations pass directly to the people named on the form, regardless of what your will says.[1]
If I have a will, do I still need a trust?
Not always. A revocable living trust can help avoid probate, keep matters private and manage assets during incapacity, but it only works if assets are actually titled to it. Whether you need one depends on your assets, your family and where you own property.
What happens in Arizona if I become incapacitated without a power of attorney?
Your family may need to petition the court to appoint a conservator for your finances or a guardian for personal and medical decisions. The process takes time, involves legal costs and comes with ongoing court oversight.
How often should I review my estate plan?
A common guideline is every three to five years, and after any major life event such as marriage, divorce, a birth or death in the family, a move to another state, a business sale or a significant change in your assets or in the law.
