Affidavit of Affixture in Arizona: Mobile Home Estate Settlement

Retirement communities across Arizona — Sun City, Mesa, Apache Junction, many parts of Tucson — are home to large numbers of manufactured and mobile homes. When the owner of one of those homes dies, families frequently assume the property transfers the same way a site-built house would: through a deed, a title transfer, or a small estate affidavit for real property.

Sometimes it does. Sometimes it doesn't. The answer depends entirely on whether an Affidavit of Affixture was recorded before the owner's death — and that one document changes everything about how the estate is settled.

What the Affidavit of Affixture Does

Under A.R.S. § 42-15203, an Affidavit of Affixture is a legal instrument that converts a manufactured or mobile home from personal property into real property. Before the affidavit is recorded, a mobile home is legally the same as a motor vehicle — it carries an ADOT/MVD title and is tracked in the motor vehicle system. After the affidavit is recorded, the home is permanently attached to the land and becomes real estate, subject to a deed and the county assessor's property tax rolls.

The affidavit serves a specific function: it creates a single, unified piece of real property combining the structure and the land beneath it. This matters for financing (mortgages rather than chattel loans), for tax assessment (real property tax rather than personal property tax or vehicle registration), and for estate settlement.

Why This Matters for Estate Settlement

The legal classification of the mobile home at the time of death determines which path the estate takes:

If an Affidavit of Affixture was recorded before death: The home is real property. It transfers using the same processes as a site-built house — a Beneficiary Deed (if one was properly recorded), Community Property with Right of Survivorship procedures, or the Small Estate Affidavit of Succession to Real Property (if net equity is under $300,000 and 6 months have passed since death). The county recorder handles the title update.

If no Affidavit of Affixture was ever recorded: The home is still titled as personal property through the ADOT Motor Vehicle Division, just like a car. It must be transferred through MVD procedures — the Non-Probate Affidavit (ADOT Form 32-6901), the $7-per-section title fee, and the standard vehicle transfer process. The county recorder's office has no authority over this transfer; it belongs to MVD.

Attempting to transfer an unaffixed mobile home through a real estate deed will produce a clouded title. Title companies and title insurers will reject it, and lenders won't finance a buyer. The heirs will eventually have to undo the error and restart through MVD — costing time, money, and possibly a lost sale.

How to Determine If an Affidavit Was Recorded

Before doing anything with a mobile home in an Arizona estate, confirm its legal classification:

1. Check the county assessor's records. Most Arizona county assessors make parcel records searchable online. Look at how the property is classified — does the assessor treat the manufactured home as real property on the parcel, or is the land and the structure separately assessed?

2. Search the County Recorder's records. An Affidavit of Affixture, if recorded, would appear in the grantor-grantee index under the owner's name and parcel number. Many county recorders have online searches.

3. Check MVD records. If no Affidavit of Affixture was recorded, the mobile home should still appear in the MVD title system. Contact ADOT or check the Arizona MVD portal for information on mobile home titles.

4. Look at tax bills. If the manufactured home is taxed as real property through the county assessor (not as a vehicle), that's a strong indicator an Affidavit of Affixture was recorded.

If you're uncertain, check with the county assessor's office directly and ask them to confirm how the structure is classified for tax purposes.

What If No Affidavit of Affixture Exists

If no affidavit was ever recorded, the mobile home transfers through MVD like a vehicle:

• Wait 30 days after the date of death (same as other personal property under the small estate affidavit rules)
• Submit ADOT Form 32-6901 (Non-Probate Affidavit) to MVD
• Pay the $7-per-section title processing fee (most manufactured homes have two sections, so $14 total)
• The estate's total personal property must still be under the $200,000 limit for the non-probate affidavit to apply

One complication: if the mobile home sits on land the decedent also owned, the land and the structure transfer separately. The land transfers as real property through the appropriate real estate process (Beneficiary Deed, CPWROS, small estate affidavit, or probate). The structure transfers through MVD as personal property. Two separate chains of title, two separate transfer processes, two sets of forms.

This split creates a practical problem for selling the combined property after the estate settles. Buyers generally want to purchase the land and the structure together. If they're on separate title instruments (a real property deed and an MVD title), the sale requires coordinating both closings simultaneously, which some title companies find cumbersome.

Recording an Affidavit of Affixture as Part of Estate Settlement

If the estate includes a mobile home sitting on land the decedent owned, and the heirs intend to keep or sell the property together as a single real estate asset, they may be able to record an Affidavit of Affixture during the estate settlement process — after the structure's MVD title transfers to the heir and before the eventual sale.

This requires:

1. Transferring the MVD title to the heir (30-day wait, Non-Probate Affidavit process)
2. The heir then recording an Affidavit of Affixture with the County Assessor and County Recorder
3. The MVD title is cancelled and the structure becomes real property on the parcel

This is worth considering if the heirs plan to sell. Converting the home to real property before listing makes it easier to finance and insure, broadens the buyer pool, and simplifies the closing. It requires the heir to already hold the MVD title, so the vehicle transfer step must happen first.

The procedures and required forms differ slightly by county. In Maricopa and Pima counties, the county assessor's office manages this process. Check with the specific county assessor for their current form requirements and fees.

The Broader Context: Arizona's Manufactured Home Landscape

Arizona has one of the highest concentrations of manufactured housing in the United States, driven largely by the retirement community market and more affordable entry price points in rural areas. This means manufactured home estate settlement is not an edge case for Arizona — it's a routine part of the probate landscape.

The legal misclassification problem — heirs assuming a mobile home is real property when it isn't — comes up frequently enough that the When Someone Dies in Arizona — Estate Settlement Guide includes a dedicated asset categorization worksheet that walks through exactly this question. The worksheet directs users to check for an Affidavit of Affixture and routes them to either the MVD or the County Recorder based on the answer.

Getting this right before you file any paperwork or make any representations to a title company prevents the kind of title defect that can delay an estate settlement by months.
