12 common will mistakes that will cost your family

After enough probate cases, the mistakes start to repeat. Most of them aren't the dramatic "child A vs child B going to court" kind. They're small and avoidable, and they cost the estate time, money, and family peace.

Here are the twelve we see most.

1. Beneficiary forms that override the will

The single most expensive mistake. You write a careful will leaving everything to your spouse, and your $400k IRA goes to your ex-wife from 2018 because the beneficiary form on the IRA still names her. The will doesn't override the form. The ex takes the IRA.

Fix: Audit every retirement account, life insurance policy, TOD/POD account every 2-3 years and after every major life event.

2. Witnesses who are also beneficiaries

If a beneficiary witnesses your will, their gift may be voided. The will is still valid; the gift to the witness isn't.

Fix: Use neutral witnesses — coworkers, neighbors, friends not in the will.

3. No self-proving affidavit

Without one, your witnesses may have to be tracked down years later to testify in probate. If one has moved or died, your will faces complications.

Fix: Notarize a self-proving affidavit at the time of signing. Available in CA, NY, TX, and most other states. Trustwise wills include it by default.

4. Naming a minor as a direct beneficiary

A 12-year-old inheriting $200k of life insurance triggers a court-appointed conservatorship — slow, expensive, not what you wanted.

Fix: Name a custodian under the Uniform Transfers to Minors Act (UTMA), or name a testamentary trust with a trustee.

5. Stale executor or guardian nominations

Your nominated executor is your sister, who died last year. You haven't updated. Now there's no clear authority.

Fix: Always name an alternate. Review every 3-5 years.

6. Specific bequests of items you no longer own

You leave "my 2018 Honda" to your nephew, then sold the Honda last year. The gift "adeems" — fails. Your nephew gets nothing in its place.

Fix: Either keep specific bequests current, or use general language ("the proceeds from the sale of any vehicle I own at death").

7. No residuary clause

The will has specific bequests but doesn't say what happens to "everything else." That residuary defaults to intestacy — meaning state law decides, which may not match your wishes.

Fix: Always include a residuary clause that distributes the remainder of the estate by percentage among your main beneficiaries.

8. Vague charity names

"$10,000 to the cancer society" is ambiguous. American Cancer Society? Susan G. Komen? A local one? Probate delay until the court figures it out.

Fix: Use the charity's full legal name and EIN. Most charities have a "leave us in your will" page with the exact wording.

9. Joint titling that defeats the will

You leave "all my property to my children" — but your home is jointly titled with your second spouse. The home passes to your spouse outside the will, and your kids get nothing there.

Fix: Reconcile titling and beneficiary forms with your will. If you want assets to flow per the will, don't joint-title them.

10. Old will that contradicts a new one

You signed a will in 2010, signed another in 2020, but didn't formally revoke the old one. Both surface in probate. Family fights ensue.

Fix: Every new will should explicitly revoke prior ones. The standard language: "I revoke all prior wills and codicils." Destroy the old original after the new one is signed.

11. Hiding the will

The will is in a safe deposit box only you can open. You die. Your family can't access the box without probate. Probate can't start without the will.

Fix: Keep the original in a fireproof home safe with the executor knowing the combination, or in a safe deposit box where the executor has joint access.

12. No will at all

About 60% of American adults don't have one. The state's intestacy statute decides everything: who inherits, in what proportions, who's appointed as guardian for minor children, who serves as administrator. Almost never matches what you'd choose.

Fix: A 20-minute will that names beneficiaries, an executor, and (for parents) a guardian solves this entirely.

Honorable mentions

Holographic wills (handwritten). Some states recognize them; many don't. Even where they're valid, they invite probate fights. Use a typed, witnessed will.

Codicils piled on codicils. Small amendments are fine, but stacking five codicils makes a will hard to interpret. After the second codicil, just sign a new will.

Out-of-date addresses. People move; beneficiaries get hard to find. Keep a separate address list with the will, updated annually.

Forgetting digital assets. Email accounts, photo libraries, crypto, password managers. Without RUFADAA-compliant authorization in the will, your executor may not be able to access them. (Trustwise wills include this clause by default.)

Not telling anyone. A perfectly drafted will is useless if no one knows it exists. Tell your executor where it is. Tell your alternate too.

The 30-minute audit

Pull out your will. Walk through each item:

• [ ] Beneficiary forms updated within last 2 years
• [ ] Witnesses are not beneficiaries
• [ ] Self-proving affidavit notarized
• [ ] No specific bequests of disposed-of items
• [ ] Residuary clause exists
• [ ] Charity names complete with legal entity + EIN
• [ ] Joint titling matches will intent
• [ ] Most recent will is the only one (old ones destroyed)
• [ ] Original is accessible to executor
• [ ] Executor and alternate both nominated and notified
• [ ] Digital-asset authorization included
• [ ] Minor children handled via testamentary trust

If everything checks out: you've avoided 95% of the probate disasters we see. If not: most of these are 5-minute fixes if you catch them while you're alive.
