A.R.S. 33-1008: Lien Waivers and the Four Required Forms

A lien waiver is the paper a contractor or supplier signs to give up the right to lien your property for a given payment. A.R.S. 33-1008 makes these waivers reliable by locking them to four standardized forms. If a waiver is not on one of those forms, it generally does not count. The most useful piece for a homeowner: a conditional waiver only takes effect once your payment actually clears the bank, so a signed waiver can never outrun the money.

The four required forms

The statute does two things at once. It blocks vague, after-the-fact attempts to wipe out lien rights, and it prescribes the exact forms that do work:

No oral or written statement purporting to waive, release, impair or otherwise adversely affect a lien is enforceable... unless the claimant executes and delivers a waiver and release that follows the forms set forth in this section.

There are four, sorted by two questions: is this a progress payment or the final payment, and is the waiver conditional or unconditional.

• Conditional waiver on progress payment and conditional waiver on final payment: effective only when the payment they reference actually clears.
• Unconditional waiver on progress payment and unconditional waiver on final payment: effective the moment they are signed, whether or not you have paid.

The difference is your whole protection. A conditional waiver says "I give up my lien for this payment, once the payment goes through." An unconditional waiver says "I give up my lien, period." You should ask for conditional waivers when you release a payment and collect unconditional waivers only after that payment has cleared.

How to use waivers when you pay

Use waivers as a swap: money for a signed release at every draw. The right sequence keeps you from paying out cash and still facing a lien.

For example, on a Scottsdale custom build with monthly draws, before you release the $60,000 March draw you collect a conditional waiver on progress payment from the contractor and the major subs. The check clears, then you collect matching unconditional waivers confirming they were paid. At the end, you exchange the final draw for an unconditional waiver on final payment from everyone. Done consistently, you reach the keys-handed-over moment with signed releases covering every dollar, and no one can lien the home for that work.

A waiver also helps clear a sub flagged by a twenty day notice : make that sub's waiver a condition of the next payment to your contractor.

How this connects to the rest of the lien rules

Waivers are the cleanup mechanism for the lien rights created by A.R.S. 33-981 . They pair naturally with your right to withhold payment under A.R.S. 33-994 : hold back the draw until the right waiver is in hand. If your home qualifies for the owner-occupied exemption in A.R.S. 33-1002 , subs are already mostly blocked, and waivers cover the rest.

Because an unconditional waiver gives up lien rights even if a check later bounces, never sign or accept one until the payment it covers has truly cleared, and use the conditional form everywhere else.
