Subcontractor Agreement — United States

Overview

A subcontractor agreement is the contract under which a general contractor (or another prime contractor) engages a subcontractor to perform a defined portion of work on a project — most commonly construction, but the structure applies equally to any layered service arrangement (e.g. a marketing agency subcontracting a specialist). US law treats this relationship as a business-to-business contract governed by the general common law of contracts and, for the sale of any goods component, Article 2 of the Uniform Commercial Code (UCC), which is adopted with local variations in 49 states (Louisiana, a civil-law-influenced jurisdiction, has adopted only part of the UCC). There is no federal statute specifically regulating subcontractor relationships, but construction subcontracting is shaped heavily by state mechanic's lien statutes, prompt-payment statutes, and licensing requirements that vary significantly and must be checked against the governing state and the state where the project is located (which may differ from the parties' home states). When to use it: whenever a contractor needs to delegate a defined scope of the work it owes to its own client (the project owner or a higher-tier contractor) to a specialized subcontractor, while remaining responsible to the owner for the overall project. Parties: the contractor (the party that engaged the subcontractor, and who typically remains directly responsible to the project owner) and the subcontractor (performing the delegated scope). Flow-down clauses: a well-drafted subcontractor agreement typically "flows down" relevant obligations from the prime contract (the contractor's agreement with the project owner) so the subcontractor is bound by the same schedule, quality, and compliance requirements the contractor owes upstream — the subcontract should reference and, where appropriate, attach or incorporate the relevant prime contract terms. Mechanic's liens and lien waivers: in most states, a subcontractor who is not paid can file a mechanic's lien against the property to secure payment, which can cloud title and disrupt the owner's financing or sale — contractors commonly require lien waivers from subcontractors (conditional, tied to actual receipt of payment, versus unconditional) as a condition of each progress payment; the specific form and effect of lien waivers is set by state statute and varies significantly. Insurance and indemnification: contractors typically require the subcontractor to carry commercial general liability, workers' compensation (mandatory in nearly every state for any employer with employees), and often builder's risk or professional liability insurance, and to indemnify the contractor for claims arising from the subcontractor's work — though many states restrict or void broad-form indemnification clauses that would require a subcontractor to indemnify the contractor for the contractor's own negligence ("anti-indemnity statutes"), so this clause must be checked against the state where the project is located. Payment terms: many states have prompt-payment statutes imposing specific payment timelines and interest penalties for late payment on construction contracts, which can override a contract's own payment schedule if it is less protective than the statute requires. Common pitfalls: failing to flow down the prime contract's key obligations; using a broad-form indemnification clause that is void under the project state's anti-indemnity statute; overlooking state-specific lien-waiver form requirements; and not confirming the subcontractor holds any required state or local contractor's license for the trade and jurisdiction, which can affect the enforceability of the subcontract itself in several states.
