The Short Version
An Arizona Personal Representative generally has 90 days after the Letters of Appointment are first issued to prepare the estate inventory.
The inventory identifies property owned by the decedent at death, its fair market value as of the date of death, whether it was community or separate property, and any mortgages, liens, or other encumbrances.
The Personal Representative may either file the inventory with the court or provide it as Arizona law and the probate rules require.
One of the Personal Representative’s earliest responsibilities is preparing the estate inventory. In Arizona, that generally means identifying probate assets and their date-of-death values within 90 days of appointment.
This guide explains what belongs on the inventory, what does not, and how to approach the task in an organized way.
The Game Rules At A Glance
- If You Find Something Later: Update the inventory with a supplementary inventory
- Time Limit: 90 days after your Letters of Appointment are first issued
- Your Mission: Build a reliable picture of the property the decedent owned at death
- For Each Asset: Record the date-of-death value, ownership character, and any attached debt or lien
Preparing the Probate Inventory
As Arizona’s Personal Representative, one of your first major responsibilities is preparing the inventory. Arizona law gives you 90 days to identify probate assets and state their values as of the date of death. Meeting that deadline matters because the inventory creates the official starting record for administration and helps everyone understand what the estate includes.
Your mission is to create a reliable snapshot of the property the decedent owned at death and its value at that time.
The inventory gives the Personal Representative, heirs or devisees, and other interested people a starting point for understanding the estate. Depending on how the inventory is handled, it may be filed with the court or delivered to the people required by Arizona law.
Why accuracy matters: An incomplete or careless inventory can create disputes, require corrections, and complicate later administration. A Personal Representative can also be liable for losses caused by a breach of fiduciary duty, so document how you arrived at important values and classifications.
The Rules of the Game: What to Hunt For and What to Ignore
Just like any good scavenger hunt, there are rules. You need to know what to include and, more importantly, what to leave out.
The “In-List”: What You’re Looking For
This is the scavenger-hunt part: identify the property, then figure out what evidence supports its ownership and date-of-death value.
- Bank and Financial Accounts: Gather statements showing the accounts and balances around the date of death.
- Vehicles: Record enough information to identify the vehicle and determine a supportable date-of-death value. Pricing guides can help, but unusual or collectible vehicles may need a more specialized valuation.
- Real Property: Identify each property and obtain support for its fair market value as of the date of death. Depending on the property and the estate, that may involve an appraisal, market analysis, or other reliable valuation evidence.
- Personal Property: Focus detail where value actually matters. Jewelry, art, collections, firearms, electronics, and other significant items may deserve individual treatment. You usually do not need a separate line item for every spatula.
- Business Interests and Investments: Identify ownership interests, stocks, investment accounts, and other financial assets, then determine what valuation information is appropriate.
- Unusual Assets: Business interests, collectibles, digital assets, cryptocurrency, firearms, and other specialized property may require additional documentation or professional guidance.
For each asset, also identify whether it was community or separate property and the type and amount of any mortgage, lien, or other encumbrance.
The “No-Fly Zone”: Don’t Guess Based on the Asset’s Name
One of the easiest inventory mistakes is deciding that something automatically belongs on — or off — the inventory without first checking how it was owned.
Before classifying an asset, look at the actual paperwork:
- How was the property titled?
- Was there a beneficiary designation?
- Was there a survivorship provision?
- Was the property owned by a trust?
- Did the decedent own all of it or only an interest?
- Was it community or separate property?
A beneficiary designation, joint ownership, trust ownership, or another transfer mechanism may change how an asset is handled after death.
The practical rule is simple: verify the ownership and transfer documents before deciding how the asset should be treated.
If the answer is unclear, flag it instead of guessing.
Your Essential Action Checklist
Start Early
- Secure estate property
- Gather bank, investment, title, deed, vehicle, and insurance records
- Photograph significant personal property
- Start one asset-tracking spreadsheet or inventory list
- Identify how each asset was owned at death
Build the Values
- Obtain support for real-property values
- Determine vehicle values
- Document valuable personal property
- Gather statements showing financial-account values around the date of death
- Flag assets that may require an appraiser or other specialist
Before the 90-Day Deadline
- Prepare the complete inventory
- Confirm community or separate property status
- Record mortgages, liens, and other encumbrances
- Decide whether the inventory will be filed with the court or delivered under Rule 50
- If it is delivered instead of filed, complete the required proof of notice
What Happens When the Hunt is Over
Once you’ve completed your draft inventory, send it to your legal team for review. They’ll help finalize it and provide execution instructions. Arizona gives you a choice (A.R.S. § 14-3706 and Arizona Rule of Probate Procedure 50). You can file the original inventory with the court and send copies only to interested persons who ask. Or you can choose not to file it — in which case you must mail or deliver a copy to each heir (in an estate with no will) or each devisee (if a will was probated), plus anyone else with an interest who requests it.
If you mail or deliver instead of filing, you still have to file a proof of notice with the court identifying everyone who received it, and how and when they received it. Arizona does not require the inventory itself to be notarized. The 90-day clock runs from the date your Letters were first issued.
Special Note: You still have to do the inventory, even if you are the only heir and you are also the Personal Representative. Arizona law excuses only two people: a special administrator, and a successor who takes over after someone else already finished it (A.R.S. § 14-3706).
Being the only heir makes handing out the property easier. It does not get you out of the inventory. Your legal team needs a full asset list anyway — for sales, transfers, banks, title companies, and taxes.
Managing Risks and Complications
Common Pitfalls to Avoid:
- Missing the 90-day deadline (can result in court sanctions)
- Undervaluing assets (potential breach of fiduciary duty)
- Including non-probate assets (creates confusion and delays)
- Failing to update inventory when new assets are discovered
- Poor documentation of asset distributions
When to Contact Your Legal Team Immediately:
- You discover significant assets not previously known
- Family disputes arise over asset valuations or distributions
- You’re unsure whether an asset is probate or non-probate
- The 90-day deadline is approaching, and the inventory isn’t complete
- You receive unexpected claims against the estate
PLOT TWISTS: When Your Scavenger Hunt Gets Complicated
The Mystery Asset:
Six months in, you discover a storage unit full of vintage comic books. File a supplemental inventory. Arizona law expects this.
The Family Feud:
Sister thinks Mom’s ring is worth $10,000. You got it appraised at $800. Document everything. Get it in writing. Keep your attorney in the loop.
The Ticking Clock:
Day 85 and you’re still waiting on that property appraisal? Call your attorney immediately. Extensions exist, but you have to ask before the deadline passes. Arizona’s probate rules let the personal representative file a motion for additional time, and that motion has to be filed before the 90 days runs out — not after. The motion has to say why more time is needed and how much.
Why Accuracy Matters
Your inventory isn’t just paperwork—it’s the foundation for the entire probate process. It affects:
- Heirs and Devisees: It gives them a clearer picture of the property being administered.
- Estate Administration: It creates a starting point for tracking sales, transfers, distributions, and later-discovered assets.
- Disputes: Good valuations and supporting records make it easier to explain how the Personal Representative reached a decision.
- Your Own Records: Statements, appraisals, photographs, and valuation notes create a paper trail if questions come up later.
Keeping detailed records (valuations, appraisals, bank statements, and photos) protects you from disputes and shows you’ve acted diligently.
Your Next Steps
Start with the asset list.
Gather the records you already have, identify the property you know about, and mark anything whose ownership or value is uncertain.
Then work through the gaps one by one.
You do not need every answer on day one, but you do need to start early enough to deal with appraisals, missing records, unusual assets, or other issues before the 90-day deadline.
Final Thought: Finish the Hunt, Then Keep the Map
The inventory does not have to solve every question about the estate. Its job is to create a reliable picture of what the decedent owned, what those assets were worth at death, and what still needs attention.
And if something turns up later, Arizona has a process for updating the inventory. The important part is to keep the records organized and correct the picture when new information appears.
Happy hunting — just remember that the goal is not to catalog every spatula in the house. It is to build an inventory you can explain and support.
