When it comes to construction projects in Arizona, contractors and suppliers often face challenges in ensuring they receive timely payment for their services. Fortunately, the mechanic’s lien is a powerful legal tool that can help protect the rights and interests of those involved in construction projects. In this article, we will explore the mechanics lien arizona, its purpose, how it works, and the steps involved in filing one. Whether you are a contractor, subcontractor, or supplier, understanding mechanics liens is crucial for safeguarding your financial interests.

What is a Mechanics Lien?

A mechanics lien, also known as a construction lien or contractor’s lien, is a legal claim placed on a property by contractors, subcontractors, or suppliers who have not been paid for their work or materials supplied. It provides a security interest in the property and serves as collateral for the unpaid debt. By filing a mechanics lien, these parties can assert their right to payment and potentially foreclose on the property if necessary.

The Purpose of Mechanics Liens

The primary purpose of a mechanics lien is to protect the rights of contractors, subcontractors, and suppliers by ensuring they receive payment for the labor and materials provided on a construction project. Mechanics liens help level the playing field and prevent unjust enrichment of property owners who might otherwise refuse or delay payment.

Mechanics Lien vs. Contractual Remedies

Unlike contractual remedies, which typically involve lengthy and expensive legal battles, mechanics liens provide a more direct and efficient way to secure payment. While contractual remedies require proving a breach of contract, mechanics liens create a security interest in the property itself, making it a powerful tool for recovering payment.

Understanding Mechanics Lien Arizona Laws

In Arizona, mechanics liens are governed by specific statutes outlined in the Arizona Revised Statutes (ARS) Title 33, Chapter 9. These laws define the rights and obligations of parties involved in construction projects, ensuring a fair and balanced approach to resolving payment disputes.

Eligibility to File a Mechanics Lien Arizona

To be eligible to file a mechanics lien in Arizona, you must have provided labor, materials, or professional services to improve the property. This includes general contractors, subcontractors, suppliers, architects, engineers, and other professionals involved in the construction process.

Preparing and Filing a Mechanics Lien

To initiate the mechanics lien process, you must prepare a preliminary twenty-day notice, which informs the property owner, general contractor, and other interested parties about your involvement and potential lien rights. This notice must be served within twenty days of starting work or supplying materials.

After serving the preliminary notice, you can proceed with filing the mechanics lien itself. This involves preparing the lien document, including the description of work or materials provided, the amount owed, and the property information. The lien must be filed with the county recorder’s office in the county where the property is located.

Serving a Preliminary Twenty-Day Notice

The preliminary twenty-day notice is a critical step in the mechanics lien process. It serves as a formal notification to the property owner that you have a potential lien claim and alerts them to the need for prompt payment. Failing to serve this notice within the specified timeframe can jeopardize your right to file a mechanics lien.

Deadlines for Filing a Mechanics Lien

In Arizona, you have a limited timeframe to file a mechanics lien after completing work or supplying materials. Generally, the deadline is 120 days from the last day you provided labor or materials. However, if a notice of completion or notice of termination is filed, the deadline may be shortened to 60 days.

Enforcement of Mechanics Liens

If the property owner fails to make payment after a mechanics lien has been filed, you have the option to enforce the lien through a foreclosure action. This legal process allows you to recover the debt by selling the property and using the proceeds to satisfy the lien amount.

Resolving Disputes and Removing Mechanics Liens

Disputes related to mechanics liens can arise during the construction project. It’s important to communicate and negotiate with all parties involved to find a resolution. If a dispute cannot be resolved amicably, legal action may be necessary to remove the mechanics lien or enforce its payment.

Release of Mechanics Liens

Once you have been paid in full, it is essential to release the mechanics lien promptly. Failing to do so can cause unnecessary delays and complications for the property owner. You can release the lien by preparing a lien release document and recording it with the county recorder’s office.

The Importance of Consulting an Attorney

Navigating the mechanics lien process in Arizona can be complex, and any missteps can have serious consequences. Therefore, it is advisable to consult an experienced construction attorney who can guide you through the process, ensure compliance with the law, and protect your rights and interests.


Mechanics liens play a vital role in protecting the rights of contractors, subcontractors, and suppliers involved in construction projects in Arizona. By understanding the mechanics lien process and following the necessary steps, you can secure your right to payment and protect your financial interests. Remember to consult with a knowledgeable attorney to ensure compliance with the law and maximize your chances of a successful outcome.
