Re: Formal Demand for Payment
Project Property: [PROJECT ADDRESS]
Invoice No.: [INVOICE NUMBER]
Outstanding Balance: $13,463.75
Dear [PROPERTY OWNER NAME(S)]:
This firm represents [CONTRACTOR NAME] (“Contractor”) concerning the unpaid balance arising from construction and improvement services performed at the property identified above (the “Property”).
Contractor completed the contracted work and subsequently addressed the corrective items the parties agreed Contractor would perform. Contractor notified you that the agreed-upon corrective items had been completed, and your subsequent written communication acknowledged completion of the corrective work.
After accounting for all payments received and adjustments previously authorized by Contractor, the outstanding balance is $13,463.75.
Accordingly, formal demand is hereby made for payment of $13,463.75 no later than 5:00 p.m. Arizona time on [PAYMENT DEADLINE].
Payment should be delivered to:
[CONTRACTOR NAME]
[PAYMENT ADDRESS]
[CITY, STATE ZIP CODE]
Payment may also be coordinated directly with Contractor by contacting [PHONE NUMBER] or [EMAIL ADDRESS].
Contractor will not provide a full release of its mechanic’s lien in exchange for less than the complete balance owed. Upon receipt and clearance of payment in full, Contractor will promptly execute and process the appropriate release of its lien in accordance with Arizona law.
If Contractor does not receive cleared payment in full by the deadline stated above, our client is prepared to pursue the dispute-resolution and collection remedies available under the parties’ agreement and applicable law. Such action may include commencing mediation, pursuing enforcement of Contractor’s mechanic’s lien within the applicable statutory period, asserting a breach-of-contract claim, and seeking all recoverable interest, attorney fees, costs, and other relief.
Nothing in this letter constitutes a waiver, modification, release, or limitation of any claim, lien, remedy, or legal right belonging to Contractor. All such rights and remedies are expressly reserved.
Please direct future communications concerning this demand to the undersigned.
Sincerely,
