New York construction litigation has long been defined by the interplay between the Labor Law and third-party practice. When a worker is injured on a job site and sues under Labor Law § 240 or § 241, the general contractor and property owner typically face near-absolute liability under those statutes. Their primary avenue for risk transfer is impleading the subcontractor whose employee was injured, pursuing contractual indemnification and the sub's failure to procure insurance as required by their subcontract. That avenue is still available under the AVOID Act, but it now comes with a strict deadline that fundamentally changes how construction defendants must operate from the moment they are served.
The Labor Law framework and why impleader matters
Labor Law § 240(1) imposes absolute liability on general contractors and property owners for gravity-related injuries to construction workers. The statute does not permit comparative fault defenses. If a worker falls from a scaffold, the GC and owner are liable, period. Labor Law § 241(6) operates similarly for regulatory violations. The result is that construction defendants routinely have no viable defense to the underlying Labor Law claim and must rely on risk transfer through impleader to manage their exposure.
Before the AVOID Act, that impleader could happen at any point before trial. Defense counsel would answer the complaint, gather information, and eventually file a third-party complaint against the relevant subcontractors, sometimes months or even years after the action began. The AVOID Act ends that practice. Once you serve your answer, the clock starts, and courts will enforce the deadline.
The deadline for construction claims
Under CPLR § 1007(b), a defendant has 90 days from serving its answer to file a third-party summons and complaint. That window applies to all third-party claims, whether grounded in contractual indemnification, failure to procure insurance, or any other theory. Without a court order, no third-party complaint may be filed after that 90-day period.
That 90-day window sounds workable until you consider what must happen within it: identifying all subcontractors with any potential involvement in the accident, locating the relevant subcontracts, confirming that enforceable indemnification and insurance-procurement language exists, verifying the sub's insurance coverage against contract requirements, and preparing and filing the third-party complaint. On a large project with dozens of subs, multiple scopes, and project records held by various parties, 90 days can disappear quickly.
For details on how these deadlines apply to specific dates and circumstances, use the deadline calculator.
The contractual chain and the 90-day window
Construction subcontracts typically require the subcontractor to indemnify the GC and owner for claims arising from the sub's work, and to name them as additional insureds on the sub's commercial general liability policy. These provisions are the foundation of risk transfer in the Labor Law context. But they are only as useful as the GC's ability to locate and rely on them under deadline pressure.
The AVOID Act creates an operational forcing function. Within 90 days of being served, a GC must be able to:
- Identify which subcontractor's employee was injured and which subcontract governs the relationship.
- Confirm that the subcontract contains an enforceable indemnification clause. New York law is strict about indemnification language; broad form indemnity against the indemnitee's own negligence must be explicit.
- Verify that the sub maintained the required insurance and that the GC is properly named as an additional insured on the applicable policy.
- Confirm that the sub's insurer received timely notice of the claim.
- Prepare and file the third-party complaint.
Any failure in that chain forfeits the GC's impleader rights. The sub and its insurer benefit without contributing to the plaintiff's recovery. The GC absorbs the entire verdict.
The note-of-issue provision
One of the sharpest provisions in the AVOID Act is the restriction on filing third-party complaints after the note of issue. Under CPLR § 1007(c), once the note of issue is filed, a third-party complaint may only be filed upon a showing of good cause or that filing is in the interest of justice. This is not an absolute bar, but it is a meaningful threshold: defendants who have allowed the deadline to pass cannot simply invoke the post-note-of-issue exception as a routine matter.
For construction litigators managing active dockets, this rule requires proactive monitoring. Cases move to note-of-issue status faster than defendants sometimes expect, particularly in active courthouses. A defendant who is tracking the 90-day deadline but is not monitoring the case calendar may find that the note of issue was filed earlier than anticipated, creating an additional hurdle to impleader.
Documentation urgency: contracts and certificates of insurance
The AVOID Act has transformed COI and contract documentation from a routine records-management function into a front-line liability issue. A GC that cannot locate a subcontract within days of service cannot evaluate its indemnification rights. A GC whose COI files are incomplete cannot confirm that its additional insured coverage is in place. Both failures directly translate into forfeited risk-transfer rights under the 90-day window.
The practical implication is that construction firms need to treat contract and insurance documentation as litigation-readiness infrastructure. COI tracking and contract accessibility are no longer back-office concerns; they are pre-litigation compliance requirements.
Platforms like TrustLayer automate COI verification across subcontractor networks, flagging expired certificates and coverage gaps against your specific contract requirements before a claim arises, so that when you are served under the AVOID Act your documentation is already in order.
The compliance checklist provides a structured 10-step process for auditing your current documentation posture and identifying gaps before you are served. The contract audit playbook walks through reviewing subcontract indemnification provisions systematically.
Subcontractors as subsequent defendants
When a general contractor successfully impleads a subcontractor, that sub becomes a third-party defendant with its own potential third-party claims against sub-subcontractors or other parties. Under CPLR § 1007(b), the sub as a subsequent defendant has the same 90-day window from serving its own answer to file further third-party complaints.
For specialty contractors who are routinely impleaded in construction cases, this means maintaining the same documentation readiness as GCs. A sub that cannot locate its sub-subcontracts quickly after being impleaded may lose its own risk-transfer rights within the same 90-day framework.
Practical steps for construction defendants
The AVOID Act demands that construction firms treat litigation preparation as an ongoing operational function, not a reactive response to service. The following steps reflect current best practice.
First, audit every active case immediately. For any pending matter in which a third-party complaint has not been filed, determine whether the 90-day period has passed or is approaching. Use the deadline calculator to run this analysis systematically.
Second, build a 48-hour response protocol for new service. When a new lawsuit arrives, the first two business days should be consumed entirely by identifying the relevant subcontractors, locating the governing contracts, confirming insurance requirements, and notifying both defense counsel and coverage counsel of the impleader deadline.
Third, assess your contract and COI management infrastructure against the standard the AVOID Act implicitly requires. If your firm cannot retrieve a specific subcontract within one business day of being served, you have a documentation gap that needs to close before the next claim arrives.
Fourth, brief your carriers. Defense counsel and coverage counsel need to be aligned on impleader decisions before the deadline. Carriers who are not familiar with the AVOID Act framework may not appreciate the urgency; raising it proactively is better than explaining a missed deadline after the fact.
The AVOID Act will expose documentation and process failures that previously remained invisible because defendants had time to paper over them. Construction firms that build the right workflows now will preserve their risk-transfer rights when claims arrive. Those that do not will absorb liability that their contracts were designed to shift.
The employer exception and its role in construction claims
One additional deadline merits attention in the construction context. Workers' Compensation Law § 11 normally bars Labor Law actions directly against employers, but an exception applies where the injured worker suffered a "grave injury" as defined by the statute. In those cases, the GC may have a viable third-party claim against the sub-employer even where no separate contractual indemnification claim exists.
Under CPLR § 1007(e), the employer exception provides 90 days from the later of: when the employer's identity becomes known, or when the defendant knows or should know the plaintiff sustained a grave injury. For construction defendants managing complex projects with numerous subs, the employer's identity may not be clear from the outset. Preserving the right to invoke this exception requires documenting when each relevant fact became known, so that the 90-day window can be measured accurately.
Use the deadline calculator to run the employer exception scenario. Where multiple theories exist against the same third party, all viable claims should be included in a single timely complaint.
