Understanding Liens and Their Priority in Arizona Real Estate

Last updated: April 2026

For aspiring real estate professionals in the Grand Canyon State, mastering the concept of encumbrances is a non-negotiable step toward passing the state licensing exam. Among the most critical encumbrances to understand are liens. A lien is a legal claim or right against a property by a creditor as security for a debt. Knowing how liens are classified, how they are enforced, and, most importantly, the order in which they are paid (lien priority) is essential for your exam and your future fiduciary duties to clients.

If you are looking for a broader overview of the testing requirements, be sure to review our Complete Arizona Exam Guide. In this mini-article, we will dive deep into the mechanics of liens, Arizona-specific statutes, and the "first in time, first in right" doctrine.

Classifying Liens in Arizona

Before understanding priority, you must understand the categories of liens tested on the Arizona real estate exam. Liens are generally classified in two ways: by how they are created (voluntary vs. involuntary) and by what they attach to (specific vs. general).

Voluntary vs. Involuntary Liens

Voluntary Liens: Created intentionally by the property owner's actions. The most common example is a mortgage or a Deed of Trust. When a buyer takes out a loan to purchase a home in Phoenix, they voluntarily allow the lender to place a lien on the property.
Involuntary Liens: Created by law without the owner's consent. These can be statutory (created by state law, such as property taxes) or equitable (created by a court order, such as a judgment lien).

Specific vs. General Liens

Specific Liens: Attach only to a single, specific parcel of real estate. Examples include property tax liens, mechanic's liens, and mortgages.
General Liens: Attach to all of the debtor's property, both real and personal. Examples include IRS income tax liens and judgment liens awarded by a court.

The Golden Rule: "First in Time, First in Right"

In Arizona, the general rule of lien priority is established by the date and time a lien is recorded in the county recorder's office where the property is located. This is known as the "first in time, first in right" principle.

For example, if a homeowner takes out a primary mortgage (recorded on January 1, 2023) and later takes out a Home Equity Line of Credit (recorded on June 1, 2024), the primary mortgage has priority. If the property is foreclosed upon, the primary mortgage gets paid in full before the HELOC lender sees a single dime.

The "Super Priority" Exceptions

The Arizona real estate exam will heavily test the exceptions to the "first in time" rule. Certain liens are granted statutory priority over all other recorded liens, regardless of when they were filed.

Property Taxes (Ad Valorem Taxes): Under Arizona Revised Statutes (ARS), ad valorem property taxes are the highest priority lien. Even if a mortgage was recorded five years before the tax bill was issued, the property tax lien jumps to the front of the line.
Special Assessments: Charges for local municipal improvements (like paving a dirt road or installing sewer lines) also hold super priority, sitting right alongside general property taxes.

Mechanic's Liens and the "Relation Back" Doctrine

A mechanic’s lien is an involuntary, specific lien filed by contractors, subcontractors, or material suppliers who have not been paid for improving a property. Arizona law (ARS Title 33) provides a unique twist on priority for mechanic's liens called the relation back doctrine.

In Arizona, the priority of a mechanic's lien does not depend on the date it is recorded. Instead, it "relates back" to the date the labor or materials were first supplied to the job site.

Exam Tip: To validly file a mechanic's lien in Arizona, a contractor must serve a Preliminary 20-Day Notice to the owner, lender, and general contractor within 20 days of first supplying labor or materials. Once the project is completed, they typically have 120 days to record the actual lien.

Real-World Scenario: The Foreclosure Waterfall

To truly grasp lien priority, you must understand how funds are distributed after a foreclosure sale. Let's look at a practical scenario. Imagine a property in Scottsdale is sold at a foreclosure auction for $350,000. The property has the following encumbrances:

First Deed of Trust (Recorded 2018): $280,000
Unpaid Property Taxes (Assessed 2024): $12,000
Mechanic's Lien (Work started Jan 2023, recorded May 2023): $25,000
Second Mortgage (Recorded March 2023): $40,000

Here is how the $350,000 is distributed based on Arizona lien priority laws:

Foreclosure Payout Waterfall ($350k Total Proceeds)

The Breakdown:

Property Taxes ($12,000): Paid first due to super priority. (Remaining funds: $338,000)
1st Deed of Trust ($280,000): Paid second as it was recorded in 2018. (Remaining funds: $58,000)
Mechanic's Lien ($25,000): Paid third. Even though it was recorded in May 2023, it relates back to January 2023 (when work started), putting it ahead of the second mortgage. (Remaining funds: $33,000)
Second Mortgage ($33,000): Gets the remaining $33,000. Because the funds ran out, they suffer a $7,000 deficiency. The lien is wiped from the property, though they may sue the borrower personally for the difference.

Other Notable Arizona Liens

Judgment Liens

A judgment lien is a general, involuntary lien created by a court decree. In Arizona (ARS § 33-964), a recorded judgment lien remains valid for 10 years and can be renewed. It attaches to all real property owned by the debtor in the county where the judgment is recorded.

HOA Assessment Liens

Arizona has robust Homeowner's Association communities. Under ARS § 33-1807, an HOA has an automatic lien on a property for unpaid assessments. However, HOA liens are generally subordinate to property taxes and the first deed of trust.

Studying for the Exam

When preparing for your exam, ensure you can quickly identify whether a lien is general or specific, and voluntary or involuntary. Just as you must strictly adhere to the rules outlined in Arizona real estate ethics and standards, you must strictly apply the statutory rules of priority to exam questions.

Because lien priority questions often involve dates and math, they can be tricky. We highly recommend reviewing our practice test strategies to learn how to diagram timeline questions. Additionally, remember that while liens are financial encumbrances, non-financial encumbrances (like easements or restrictions required for ADA compliance in real estate) also affect property transferability and are heavily tested.

Frequently Asked Questions (FAQs)

1. Does an IRS tax lien supersede an Arizona property tax lien?

No. Ad valorem property taxes and special municipal assessments hold the highest priority in Arizona. Even a federal IRS income tax lien is subordinate to local property tax liens.

2. How long does a judgment lien last in Arizona?

In Arizona, a judgment lien is valid for 10 years from the date it is recorded. It can be renewed for additional 10-year periods if the renewal is filed before the original lien expires.

3. What happens to junior liens if a foreclosure sale doesn't generate enough money to pay them?

If foreclosure proceeds run out before reaching junior lienholders, those liens are generally extinguished (wiped out) from the property title. The creditor loses their security interest in the home, though they may still attempt to pursue the debtor personally for the unpaid debt (an unsecured deficiency judgment).

4. What is a Preliminary 20-Day Notice in Arizona?

It is a mandatory legal notice that contractors, subcontractors, and materialmen must send to the property owner, general contractor, and lender within 20 days of first providing labor or materials. If they fail to serve this notice, they lose their right to file a valid mechanic's lien later.

5. Are HOA liens superior to a first mortgage in Arizona?

Generally, no. Under Arizona law, HOA assessment liens are subordinate to (lower priority than) property taxes, special assessments, and a recorded first mortgage or first deed of trust.
