1. Core Elements and Burden of Proof
To prevail in a construction payment claim, you must establish four foundational elements:
(1) a valid contract or agreement to perform work or supply materials;
(2) performance of that work or delivery of materials in accordance with the contract;
(3) the other party's breach, typically by non-payment or underpayment; and
(4) quantifiable damages resulting from the breach.
The burden rests on the claimant throughout. Courts do not presume payment or infer damages; you must present evidence that proves each element by a preponderance of the evidence.
| Element | What You Must Show | Common Defense |
|---|---|---|
| Valid Contract | Written agreement, email chain, or conduct showing mutual assent to terms and price | No meeting of minds; oral agreement unenforceable |
| Performance | Work completed, materials delivered, or services rendered as promised; invoices, photos, timesheets | Work deficient, incomplete, or non-conforming; counterclaim for repair costs |
| Breach | Proof of non-payment, partial payment, or payment refusal; demand letter or prior communication | Payment made; dispute over amount or scope; set-off claim |
| Damages | Invoice amount, contract price, or cost of materials; documentation linking non-payment to loss | Damages speculative, inflated, or unrelated to breach |
In New York contract disputes, courts apply the objective theory of contract formation. If the defendant argues no enforceable agreement existed, you must present evidence of mutual assent, such as a signed contract or email confirmations. Vague pricing, undefined scope, or conflicting communications can undermine your burden. The defendant may also assert an affirmative defense such as payment made, set-off rights, or a counterclaim for defective work, which shifts the evidentiary focus mid-dispute.
2. Documentation and Evidence Preservation
Your strongest position depends on preserving a contemporaneous written record. Begin documenting before work starts and continue through completion and payment. Preserve all contracts, change orders, invoices, delivery receipts, photographs, time records, and communications with the other party. Courts in New York place substantial weight on documentary evidence, particularly invoices and lien notices that comply with statutory requirements.
Mechanics' lien claims in New York require strict compliance with notice and filing deadlines. If you are a subcontractor or material supplier, you must serve a notice of non-payment within a specified window (often 30 days after first furnishing labor or materials to the project), and file a lien statement with the county clerk within defined timeframes. Failure to provide timely notice or file within the statutory deadline bars your lien claim entirely, even if the underlying debt is valid. This procedural defect is not forgivable; courts do not grant relief for late filings absent extraordinary circumstances.
Retain invoices showing the date, description, quantity, and price of work or materials. Email chains and text messages that reference performance or payment disputes are admissible and often persuasive. Photographs of completed work and material deliveries corroborate your account. Time records and equipment logs establish the scope and duration of work. If payment was partial, retain evidence of what was paid and when, so you can calculate the shortfall with precision. The defendant's payment records, bank statements, or canceled checks are equally important; if the defendant claims payment was made, you need documentary proof to dispute that claim.
3. Procedural Posture and Timing
Construction payment claims may proceed as breach of contract actions, unjust enrichment claims, or mechanic's lien foreclosures, depending on the parties and facts. Each path carries different deadlines, filing requirements, and remedies. The statute of limitations for breach of contract in New York is generally six years from the date of breach; however, mechanic's lien claims are subject to much shorter filing windows. If you delay in asserting your claim, you risk losing the right to a lien, even if the underlying contract claim survives.
New York Small Claims and Contract Actions
If your claim is under $5,000, you may file in Small Claims Court, where procedures are simplified and no attorney is required. For claims exceeding $5,000, you file in Supreme Court or County Court as a breach of contract action. In Supreme Court, you must serve the defendant with a summons and complaint, and the defendant has 30 days to respond. Discovery follows, often spanning months. Many construction disputes settle during discovery once both parties exchange invoices, photographs, and communications. If settlement fails, the case proceeds toward trial or summary judgment, where the judge or jury evaluates your evidence against the defendant's defenses.
Mechanic'S Lien Claims and Foreclosure
A mechanic's lien is a statutory claim that attaches to the property on which you performed work or supplied materials. In New York, a general contractor or subcontractor must file the lien within 90 days after the last date materials were furnished or labor was performed. A material supplier has 120 days. These deadlines are absolute; missing them forecloses your lien remedy. Once filed, the lien remains on record and can pressure settlement, but you must then file a foreclosure action within two years to enforce it. Lien foreclosure is a separate lawsuit in which you seek a judgment to sell the property and satisfy your claim from the proceeds.
4. Common Defenses and Counterattacks
Expect the defendant to raise defenses that challenge your burden of proof or assert affirmative claims that reduce recovery. The most frequent defenses are non-payment denials, work deficiency claims, payment-made assertions, and set-off arguments. Understanding these defenses helps you anticipate weaknesses in your evidence and bolster your documentation before litigation begins.
Non-payment denial occurs when the defendant claims payment was made or disputes the amount owed. If you have no written record of payment and the defendant produces a bank statement or canceled check, the burden shifts to you to explain the discrepancy. Maintain a payment ledger showing every payment received, the date, amount, and method. Work deficiency is a potent defense: the defendant may argue that work was incomplete or performed below contract standards. To counter this, preserve photographs and testimony from job site inspections, written communications acknowledging satisfactory performance, and any final sign-offs that document what was completed. Set-off claims allow the defendant to reduce what they owe by the cost of defects. This defense does not eliminate your claim but may reduce recovery.
Statute of limitations defenses rarely bar construction payment claims within the six-year window, but mechanic's lien claims face much tighter filing deadlines that courts enforce strictly. If you miss the 90-day or 120-day window to file a lien, that remedy is lost regardless of the underlying contract claim's viability. Procedural defects in notice or service can also bar recovery if the defendant raises them promptly.
5. Strategic Considerations and Next Steps
Before initiating litigation or filing a lien, evaluate whether your documentation meets the burden of proof for each element. Review your contract and confirm the scope, price, and payment terms are clear. Calculate damages precisely: identify the invoice amount, any partial payments, and the outstanding balance. If the defendant raises a deficiency claim, assess whether you can rebut it with photographs or communications.
Timing is critical. If you plan to pursue a mechanic's lien, file it within the statutory window (90 or 120 days, depending on your role). Do not assume the lien can wait; once the deadline passes, it is gone. If you are negotiating with the defendant, document every communication and send a formal demand letter before filing. This letter creates evidence of breach and may support a claim for attorney fees if your contract includes a prevailing-party clause.
