How to Respond to Construction Subcontract Agreement Disputes

New York Lien Law Section 34 grants subcontractors a right to file a mechanics lien against the property if they are not paid for labor, materials, or services. However, this right is forfeited if the subcontract contains a waiver of lien rights that is signed before or concurrent with payment. Courts in New York have upheld broad waiver language, so the specific wording in your agreement is critical. Many subcontracts require a final waiver of all lien rights as a condition of final payment, which is enforceable; the risk arises when preliminary waivers are demanded before partial payments are made. From a strategic standpoint, subcontractors should negotiate for conditional waivers, meaning the lien right is waived only upon actual receipt of funds, not upon invoice or submission of a waiver form.

Retainage, the amount withheld from each payment (typically 5 to 10 percent), is standard in construction but creates cash flow strain for subcontractors. Your agreement should specify when retainage is released, whether it is released upon substantial completion or only upon final project completion, and what conditions must be met for release. Disputes often arise when a general contractor retains funds indefinitely or uses retainage as leverage to force the subcontractor to correct alleged defects. New York courts have found that unreasonable withholding of retainage may constitute a breach of the implied covenant of good faith and fair dealing, but the burden of proving unreasonableness falls on the subcontractor. Clarify in writing the release schedule and any objective milestones tied to retainage release.

A robust change order clause should require that any change to scope, schedule, or cost be documented in writing and signed by authorized representatives before the work is performed. Many subcontracts allow the general contractor to unilaterally direct changes, with the subcontractor's compensation to be determined later, which shifts risk to the subcontractor. In practice, these cases are rarely as clean as the contract suggests. A subcontractor who performs work without a signed change order and then disputes the compensation faces an uphill battle in proving the value of the work or that it fell outside the original scope. Require explicit authorization and written confirmation of any change before proceeding.

New York General Obligations Law Section 5322 prohibits indemnification for a contractor's own negligence in construction contracts. This means a subcontract clause requiring the subcontractor to indemnify the general contractor for the general contractor's own negligence is void and unenforceable. However, the statute applies only to construction contracts and does not eliminate indemnification for the subcontractor's own negligence or for comparative negligence scenarios. Courts have found that indemnification for comparative negligence (where both parties are partially at fault) may be enforceable if the language is explicit. Negotiate for mutual indemnification tied to comparative fault, and ensure insurance requirements align with the indemnity obligation. Related practice areas, such as agency agreements and risk allocation structures, can inform how indemnity obligations interact with project governance.

Your agreement should specify the types and limits of insurance required (general liability, workers compensation, builder's risk, etc.), who is the named insured, and whether the subcontractor's policy must name the general contractor or project owner as an additional insured. Many disputes arise when a claim occurs and the subcontractor's insurance does not cover the loss or does not name the required additional insureds. Obtain proof of insurance before commencing work, and verify that the certificate of insurance matches your contract requirements. Do not rely on verbal assurances or generic certificates; require a detailed certificate that specifies coverage limits, policy numbers, and endorsements.
