Utah Probate Deadlines: The Complete Timeline Every Executor Must Know

Utah probate runs on a tightly defined set of legal deadlines. Miss the right ones and you can't open the estate, close it, or pass anything to heirs. Miss the wrong ones and you open yourself up to personal liability.

Here's every significant deadline in Utah probate, in the order it hits you.

Deadline 1: 120 Hours After Death — The Filing Wait

Before anyone can file a probate application in Utah, at least 120 hours (five calendar days) must pass from the decedent's date of death. This is the 120-hour rule, embedded in Utah's Uniform Probate Code.

The reason is simple: to prevent probate from being opened before it's certain the decedent is actually dead (historically relevant in cases of medical uncertainty) and to give close relatives who survived by only a short time the chance to fully predecease or survive for purposes of inheritance.

If a potential heir died within 120 hours of the decedent, Utah law treats that heir as having predeceased the decedent entirely — they inherit nothing, and their own heirs don't inherit through them from this estate.

You cannot shorten this wait. Even if you have all the forms ready and the filing fee in hand, no district court in Utah will accept a probate application filed before the 120-hour period has elapsed.

Deadline 2: Three Years After Death — The Statute of Limitations to File

At the other end of the timeline, Utah Code 75-3-107 sets a three-year statute of limitations on filing a standard informal or formal probate application. If more than three years have passed since the date of death, you cannot simply file a routine probate application.

Instead, the estate must pursue a "Determination of Heirs" proceeding — a more complex equitable action that typically requires an attorney and a court hearing. The longer you wait past three years, the harder it becomes to establish ownership, locate heirs, and clear titles.

The three-year clock starts on the date of death. It doesn't pause for ignorance of the law or family disagreements about who should be the executor.

Deadline 3: Thirty Days Before Using the Small Estate Affidavit

If the estate qualifies as a small estate — no real property, total assets under $100,000 excluding up to four vehicles — Utah law lets successors use a Small Estate Affidavit to collect assets directly from financial institutions without going through probate at all. But there's a mandatory 30-day waiting period from the date of death before this affidavit can be used.

This prevents immediate collection of assets before it's confirmed that no formal probate will be opened.

Deadline 4: Three Months After Appointment — The Inventory

Once you're appointed as personal representative (once the court issues Letters Testamentary or Letters of Administration), you have three months to prepare and complete a formal inventory of all estate assets. This is required under Utah Code 75-3-705 and includes fair market values for every item as of the date of death.

Three months sounds generous until you factor in delays in getting appraisals for real estate, tracking down investment statements from multiple institutions, and valuing business interests. Start the inventory process in your first week of appointment, not your last week before the deadline.

Deadline 5: Three-Month Creditor Window

After publishing notice to creditors in a newspaper of general circulation (running for three consecutive weeks), unknown creditors have three months from the date of first publication to file claims against the estate. Under Utah Code 75-3-801, claims filed after that window are forever barred.

For known creditors — those whose identity and debt you're aware of — you must mail written notice directly. They have 60 days from that mailing, or 90 days from first publication, whichever is later.

The creditor window is what determines the earliest you can safely distribute estate assets to heirs. You must wait until this window closes before making any distributions, or you become personally liable for creditor claims paid out of your own pocket.

Deadline 6: One Year After Death — The Absolute Bar

If the personal representative never publishes notice to creditors and never mails individual notice, Utah Code 75-3-803 provides a backstop: all claims against the estate are absolutely barred one year after the date of death, regardless of their validity.

This sounds like a way to avoid the creditor notice process, but it's not a strategy — it means the estate remains exposed and distributable for a full year, rather than the three months it takes to properly run the creditor notice process. Publishing notice is always faster.

Deadline 7: Four Months After Appointment — Earliest Estate Closing

Utah Code 75-3-1003 prohibits closing an informal probate estate earlier than four months after the personal representative's appointment. Even if everything else is wrapped up — creditors paid, inventory complete, taxes filed — you must wait the full four months.

Combined with the inventory deadline and creditor notice period, the practical minimum from appointment to closing is:

• Months 1–3: Complete inventory
• Months 1–3: Publish creditor notice, run the 90-day window
• Month 4: Close (assuming creditor window closed and all claims resolved)

Most Utah informal probate estates close between five and nine months after appointment when you account for real-world delays.

Deadline 8: One Year After Closing — Discharge Clock

After you file the Closing Statement, a final one-year clock runs. If no interested party files legal proceedings against you within that year, your appointment automatically terminates and you're discharged from personal liability as personal representative.

If someone does file a challenge within that year — contesting the accounting, claiming a distribution was improper, alleging creditor claims were paid in the wrong order — the clock stops and you remain personally exposed until the court resolves it.

The Risk of Letting Deadlines Slip

The most dangerous deadline is the three-year filing deadline. Families sometimes avoid probate out of inertia or family conflict, only to discover three years later that the decedent's home is titled to an estate that can no longer be probated through normal channels. This is common with investment properties or vacation cabins that no one is actively living in or selling.

If you inherited responsibility for settling an estate and time has already passed, the Utah Probate Process Guide explains both the standard informal probate process and when you need professional legal help — including for post-deadline situations.
