Intent To File FAQ

Not sending an Arizona notice of intent to lien has no bearing on your lien claim since it is not required.

Mechanics Lien FAQ

An Arizona mechanics lien is an effective tool that helps make sure you will be paid for the construction materials and/or labor you supplied. It is a legal claim that guarantees payment for contractors.

This means that if you file a valid mechanics lien on a project you worked on in Arizona and weren’t paid for your work, you have the right to enforce the lien through a lawsuit. This enforcement action can either prompt the client to settle or force the sale of the property. The proceeds of the sale will be used to settle your unpaid bill.

With an Arizona mechanics lien, you have an interest in the improved property. When a mechanics lien is filed on the property you worked on, the property becomes collateral for uncollected payments.

Most parties who provide labor, services or materials for a construction project in Arizona pursuant to a contract may file a mechanics lien.¹

Design professionals who have a written contract with the property owner or have an oral or written contract with an architect who has a written contract with the property owner are covered by the right to lien.

Only parties who have a written contract with the owner-occupant of a property may file a lien against it.

Suppliers to suppliers cannot file an Arizona mechanics lien.

These are the steps to follow in filing an Arizona mechanics lien. 

Step 1: Ready the lien form and fill it out with all of the required information, which you can find below. A notary must acknowledge the signature of a party. Remember that notarizing the document is required in filing it. Many Arizona states are strict when it comes to the quality of the form submitted, so make sure that the copy you send is of good quality and without any unnecessary lines or images on it lest your filing be rejected.

Step 2: File the original notarized copy of the form with the clerk’s office in the county where the property is situated. 

  • The notarized form may be sent to the clerk’s office via mail or FedEx, or you can deliver it in person for recording. In some Arizona counties, you may e-record the document. 
  • If you are e-recording the lien form, the fees for filing and processing will be assessed before recording. On the recording platform, just select “Lien” and upload your lien and other required attachments. 
  • If you choose to send the lien via mail or FedEx or walking in with it, include the proper fees in your filing.

Call the county recorder to know the amount you have to pay. If you don’t pay the right amount of fees, your lien can be rejected. 

The fees are usually determined by the amount set for the first page plus the sum of the smaller amounts set for the succeeding pages. This means that the more pages you include in your filing, the higher the fee will be.  

Step 3: Ask for a stamped copy of your recorded lien. 

  • Include a self-addressed stamped envelope in your filing, along with the filing fee, in order to receive a copy of your recorded lien for you own records.

Step 4: Arizon law requires that you serve your mechanics lien on the owner of the property “within a reasonable amount of time” of filing. The best way to go about it is to serve the lien immediately.

An Arizona mechanics lien must be filed within 60 days of sending a Notice of Completion or within 120 days of project completion.² The claimant has up to 6 months after recording the lien to enforce it. 

An Arizona mechanics lien is effective for 6 months after it is filed.

Arizona requires the following pieces of information to appear on the mechanics lien form: 

  • A legal description of the lands and improvements subject to the lien
  • The name of the owner or reputed owner of the property, and the name of the person who employed the lienor and to whom materials or labor was delivered
  • If the contract is oral, a statement of the contract’s terms, time given and conditions; if it is written, a copy of the contract
  • A statement of the demand of the lienor after deducting credits and offsets
  • A statement of the date of the completion of the building or improvement, or any alteration or repair done
  • A statement of the date the 20-day Preliminary Notice was given; a copy of the notice and the proof of mailing should be attached to the lien

Arizona law dictates that a person required to have a valid license to furnish materials or labor but does not have one is not covered by lien rights.

Arizona has legislatively designed lien waiver forms which it requires claimants to use. Any lien waiver used that does not conform to the mandated design will be considered invalid.³

A lien release in Arizona is due within 20 days after the lien has been satisfied.

If a lien release is not filed within the time allowed, the lien claimant will be told to pay $1,000 and held liable to damages.

Arizona generally does not favor contingent payment clauses such as pay if paid and pay when paid ones. 

In order for these clauses to be enforceable, they must clearly and plainly state that the risk of non-payment by the owner is shifted to contractors.
