How to Make a Will in Utah: 9 Critical Mistakes to Avoid

Utah Code § 75-2-502 is clear: a will must be signed by the testator in the presence of two adult witnesses, who then sign in each other's presence. Both steps matter. Miss either, and probate courts have grounds to reject the document outright.

Every time I've seen a will challenged in probate, the first thing the opposing attorney checks is the witness line. A Utah couple who used their adult children as witnesses — both of whom were named beneficiaries — created a dispute that took 14 months to resolve. Utah generally follows the "interested witness" rule: a beneficiary can serve as a witness, but their bequest may be voided or reduced to what they'd receive intestate. Don't test that rule.

Two co-workers, neighbors, or friends who will receive nothing from the estate. That's your witness list. Simple. No exceptions worth taking.

Utah does recognize holographic wills — entirely handwritten and signed by the testator, with no witnesses required — under Utah Code § 75-2-502(b). That sounds like a shortcut, but it's a narrow legal exception with real limits.

The entire document must be in the testator's handwriting. Printed portions, typed fill-in-the-blank forms with handwritten answers, or a mix of handwriting and preprinted text can destroy holographic status. Courts have rejected wills where a testator used a printed template and filled in the blanks by hand. The printed language contaminated the document.

Worth knowing: even a valid holographic will can invite credibility disputes during probate. Someone will claim the handwriting isn't yours, or that you lacked capacity when you wrote it. A witnessed, formally executed will is harder to attack.

Utah requires "testamentary capacity" at the time of signing. That means you must understand: the nature of a will, the extent of your property, who your natural heirs are, and how the will distributes your assets. This is a lower bar than full legal competence — someone with early-stage dementia may still have capacity on a good day — but it's a bar you must clear at the moment of execution.

Clients who come to me after a contested will challenge almost always face the same fact pattern: an elderly testator signed a will close to death, with limited medical documentation of their mental state. The fix is straightforward: have your attorney document the capacity evaluation in writing at the signing meeting, and if there's any medical concern, get a contemporaneous physician statement.

No attorney can guarantee a will won't be challenged. But a documented capacity assessment makes that challenge far more expensive for the challenger to pursue.

A residuary clause catches everything your will didn't specifically name. Without one, any asset acquired after signing — a new bank account, an inheritance you received, a car you bought last spring — passes under Utah's intestacy laws, not your instructions. That may mean your estate goes to people you didn't intend to benefit.

Here's a concrete scenario: a Salt Lake City resident left specific bequests for her home, her retirement accounts, and her jewelry. She acquired a $40,000 investment account two years after signing. No residuary clause. That account passed to her estranged sibling under intestacy — not her three named friends. A single paragraph would have prevented it.

Standard language: "I give the rest, residue, and remainder of my estate to [named beneficiary]." Every will needs it.

This is where estate planning gets genuinely complicated, and where the most dollars are often at stake. Retirement accounts, life insurance policies, jointly held property, and payable-on-death bank accounts all transfer by beneficiary designation or operation of law — your will has no authority over them.

A Provo-area man updated his will after a divorce, correctly removing his ex-wife. He forgot to update the beneficiary designation on his $280,000 401(k). The ex-wife received the account. The will was irrelevant to that asset. Courts have consistently upheld beneficiary designations over contradictory will language — as established under federal ERISA law for retirement accounts, state courts have little discretion here.

Review every beneficiary designation every time your will changes. Treat them as part of the same document, even though legally they're not.

• 401(k), IRA, and employer pension accounts
• Life insurance policies
• Jointly titled real estate (with right of survivorship)
• Payable-on-death (POD) bank and brokerage accounts
• Transfer-on-death (TOD) vehicle titles — Utah allows these

If your sole beneficiary dies before you and you named no contingent (backup) beneficiary, the bequest lapses. In Utah, lapsed gifts generally fall into the residuary estate — but only if you have a residuary clause. No residuary clause, no contingent beneficiary? That share goes through intestacy.

Utah does have an anti-lapse statute under the Uniform Probate Code that saves certain gifts to descendants who predecease you — but it only applies to gifts to grandparents or closer relatives, and it doesn't apply to all relationships. Don't rely on it. Name a contingent beneficiary for every significant bequest. Takes thirty seconds to add one line; saves months of probate uncertainty.

A valid, perfectly executed will locked in a safe deposit box that your executor can't access until after probate — which requires a court order to open — is a real problem. Honestly, this is where most people go wrong after they do everything else right. The will exists. No one can get to it.

Utah doesn't have a statewide will registry, but the Clerk of the District Court in your county will accept a will for safekeeping during your lifetime for a nominal fee (typically $10–$25). Alternatively, store the original with your estate planning attorney, give a copy to your executor, and tell your executor where the original lives. At minimum, store it in a fireproof home safe — and give your executor the combination now, not in the will.

Utah law has specific rules about what happens when life changes outpace your will. Divorce automatically revokes bequests and appointments made to your ex-spouse under Utah Code § 75-2-804 — but only for the ex-spouse, not their family members you may have named. Marriage after execution of a will doesn't automatically revoke it in Utah (unlike some states), but a new spouse may have elective share rights regardless.

A new child not mentioned in your will won't be entirely disinherited under Utah's pretermitted heir statute, but the remedy is unpredictable and the share may not match what you'd have intended. Update your will within 90 days of any of these events:

• Marriage or divorce
• Birth or adoption of a child
• Death of a named beneficiary or executor
• Significant change in assets (acquisition or sale of major property)
• Moving to or from Utah from another state
• Change in relationship with a named guardian for minor children

Utah allows — and estate planning attorneys strongly recommend — attaching a self-proving affidavit to your will at signing. This is a notarized statement from your witnesses confirming they watched you sign and that you appeared competent. It's authorized under Utah Code § 75-2-504.

Without it, your witnesses may need to appear in probate court to authenticate the will. Witnesses move, get sick, die. Finding someone who signed a document 15 years ago to testify is not always possible. The affidavit lets the will be admitted to probate without live testimony. Most Utah notaries can complete the affidavit at the signing appointment for $10–$25. There is no reasonable argument against doing this.

Utah's self-proving affidavit requirement follows the Uniform Probate Code, which has been adopted in whole or in part by the majority of U.S. states — though the specific form language varies, so use Utah's version.
