On any construction job, knowing exactly who you owe and how much is what keeps payment problems from turning into liens. Preliminary notices tell you that upfront; lien waivers close the loop once you pay. This is how both work, what happens when you ignore them, and how APARBooks tracks the whole cycle.
What a preliminary notice is
A preliminary notice is a document sent by contractors, suppliers, or equipment lessors to inform a project owner about their work on a construction project. It is a proactive communication tool: it keeps every party in the payment chain informed and heads off payment problems before they start.
- Who receives it. The project owner, and often the lender, general contractor, and other top-tier parties in the payment chain.
- State requirements. Many states require subcontractors and suppliers to send a preliminary notice to preserve their right to file a mechanics lien if they are not paid.
- What it's called. Depending on the state, it may be a Notice to Owner (NTO), a Notice of Furnishing, a pre-lien notice, or a similar term.
- When it's sent. At the start of a project, before any payment disputes or due payments arise.
Why preliminary notices matter for general contractors
A general contractor running several projects and hundreds of transactions loses track of who is owed what. Preliminary notices pull that back into view:
- Timely payments. Everyone gets paid on schedule, which keeps cash flow steady.
- Legal protection. Fewer disputes and clear adherence to payment laws.
- Better project management. Payment communication stays organized.
- Transparency. Clear records of financial transactions build trust.
- Risk management. Problems get spotted early, while there is still time to fix them.
What ignoring preliminary notices costs
- Mechanics liens. An unpaid preliminary lien can become a mechanics lien on the property, complicating a sale or refinancing.
- Legal and financial costs. Ignoring liens leads to legal battles, lawyer fees, court expenses.
- Project delays. Lien disputes can stop work, adding delay and cost.
- Damaged relationships. Non-payment hurts relationships with subcontractors and suppliers and can affect future projects.
- Higher costs later. Future subcontractors may demand payment upfront.
- Reputation damage. Public disputes and liens make it harder to find partners or investors.
The lien release process, step by step
Once payments start, lien releases confirm that everyone is settled. The sequence usually runs:
- Obtain conditional releases. Get a conditional lien release from each subcontractor or supplier, stating that lien rights are conditionally waived until payment is received.
- Make the payment as the contract specifies.
- Secure unconditional releases. Once payment is confirmed, request an unconditional release waiving lien rights for the paid amount.
- Document and keep records of every payment and lien release. Records are what resolve disputes and prove compliance.
- Follow legal and compliance rules. Use the specific forms your state requires and meet the deadlines.
- Final inspection and release. Before final payment, inspect or approve the work, then get a final unconditional release covering all project work so there are no further claims.
How APARBooks tracks notices and waivers
APARBooks manages preliminary notices and payment obligations from start to finish. Before you issue any payment, APARBooks shows the relevant preliminary notices directly on the payment page, so you can confirm the status of every notice before proceeding.
After you make a payment, APARBooks can automatically generate a lien waiver confirming the subcontractor or supplier was paid in full and waives their lien rights.
APARBooks generates all four waiver and release forms, conditional and unconditional, for progress and final payments, with 13 specific versions to match local lien laws. You create and send them by print or email directly from the interface.
What you get

- State-specific compliance. 13 tailored waiver forms for state lien laws.
- The right release type. Conditional or unconditional, selected automatically for progress or final payments.

Frequently Asked Questions
What is a preliminary notice in construction?
A preliminary notice is a document sent by contractors, suppliers, or equipment lessors to inform a project owner about their work on a project. It keeps everyone in the payment chain informed and, in many states, preserves the sender's right to file a mechanics lien if they are not paid.
What are the four types of lien waiver?
Conditional waiver on a progress payment, unconditional waiver on a progress payment, conditional waiver on final payment, and unconditional waiver on final payment. A conditional waiver takes effect only once payment is received; an unconditional waiver takes effect on signing.
What happens if a general contractor ignores preliminary notices?
An unpaid claim can become a mechanics lien on the property, which complicates a sale or refinancing and can lead to legal costs, project delays, damaged relationships with subs and suppliers, and reputation damage.
How does APARBooks help manage lien waivers?
APARBooks shows relevant preliminary notices on the payment page before you pay, then automatically generates the matching lien waiver after payment. It offers 13 state-specific versions of the four waiver types and lets you send them by print or email.
When should a preliminary notice be sent?
At the beginning of a project, before any payment is due or disputed.
