New York’s AVOID Act: New CPLR 1007 Deadlines for Third-Party Claims in Construction Litigation
New York construction litigation frequently involves parties beyond those originally named in a lawsuit. An owner may sue a general contractor for defective work, even though the work at issue was performed by a subcontractor. A subcontractor may contend that another trade, supplier, or design professional actually caused the problem. These disputes frequently give rise to claims for contractual indemnification, contribution, or other forms of recovery among the various participants in the project.
New York’s new AVOID Act significantly changes the rules governing these third-party claims. Effective April 18, 2026, the Avoiding Vexatious Overuse of Impleading to Delay Act amended CPLR § 1007, which governs third-party practice, or "impleader," in New York. For actions subject to the new law, defendants generally have 90 days after serving their answer to file a third-party complaint without obtaining court approval. The new deadline makes the early evaluation of potential third-party claims, including claims for contractual indemnification and contribution, even more important for contractors, owners, developers, and others involved in New York construction litigation.
What Changed Under New York’s AVOID Act?
A defendant that believes another party may be liable for all or part of the plaintiff’s claim can bring that party into the lawsuit through a third-party action, a procedure known as “impleader.” Previously, CPLR § 1007 did not establish a specific deadline measured from the service of the defendant’s answer for commencing a third-party action. The AVOID Act changes that. Under CPLR § 1007(b), a defendant may not file a third-party summons and complaint more than 90 days after serving its answer unless the court orders otherwise. The same restriction applies to a third-party defendant that seeks to bring yet another potentially responsible party into the lawsuit.
The Act also shortened the time for service. Under amended CPLR § 1007(a), the third-party summons and complaint, together with the prior pleadings in the action, must be served on the third-party defendant within 20 days after filing. A copy of the third-party complaint must also be served on the plaintiff’s attorney within that same period.
These requirements apply to actions commenced on or after April 18, 2026.
Why Did New York Change the Third-Party Practice Rules?
The Legislature enacted the AVOID Act to address the use of late third-party claims as a source of delay in civil litigation. The legislative history explains that the Act was intended to establish time limits for impleading additional parties and prevent defendants from postponing the addition of known or identifiable parties in a manner that delays the underlying case.
The Act originally enacted in December 2025 contained a series of different deadlines depending upon the nature and sequence of the third-party claims. Before those provisions became effective, however, the Legislature enacted a chapter amendment to simplify the procedure. The final version of the Act replaced those varying deadlines with the general 90-day rule that is now contained in CPLR § 1007(b). The result is a much clearer timetable: absent a court order, third-party practice ordinarily must begin within 90 days after the party seeking impleader serves its answer.
Third-Party Claims After the Note of Issue
The AVOID Act also addresses attempts to add parties late in a case. Under CPLR § 1007(c), once a note of issue has been filed, a defendant or third-party defendant may not file a third-party summons and complaint unless the court permits it upon good cause shown or in the interest of justice. A third-party action filed in violation of that requirement may be severed or dismissed without prejudice.
This provision addresses a different concern than the 90-day rule. The filing of a note of issue generally represents that discovery has been completed and the case is ready for trial. Adding another party at that stage can result in additional pleadings, discovery, depositions, motion practice, and potentially significant delay. The AVOID Act therefore places increasingly greater restrictions on impleader as the litigation progresses.
What Does the AVOID Act Mean for Construction Litigation?
Although the AVOID Act applies to civil litigation generally, its impact can be particularly significant in construction cases because a single claim may implicate numerous parties and several levels of contracts. Consider an owner’s claim that water infiltration caused extensive damage to a building. The owner may sue only the general contractor, while responsibility for the alleged condition potentially involves the roofing subcontractor, window contractor, waterproofing contractor, mason, architect, or engineer. The general contractor’s potential claims against those parties may depend not only upon who performed the allegedly defective work, but also upon indemnification provisions and other risk-allocation terms contained in the project contracts.
The new law does not require a defendant to implead every potentially responsible party within 90 days or forever lose its substantive rights. CPLR § 1007 expressly permits a court to authorize a third-party complaint after the 90-day period. The significant change is procedural: after 90 days, impleader is no longer available as of right and requires court approval. That distinction is important. The expiration of the 90-day period does not itself extinguish an otherwise valid contractual indemnification or contribution claim. It does, however, affect whether and how that claim can be asserted against another party in the pending lawsuit.
The Bottom Line
The AVOID Act represents a significant change to New York third-party practice. For actions commenced on or after April 18, 2026, CPLR § 1007 now generally establishes three important procedural rules: a third-party complaint filed more than 90 days after service of an answer requires court approval; the third-party pleadings must generally be served within 20 days after filing; and impleader after the filing of a note of issue requires a showing of good cause or that allowing the claim is in the interest of justice.
For participants in construction projects, the practical effect is that third-party claims can no longer be treated as an issue that will necessarily be addressed later in discovery. When a construction lawsuit is filed, the contracts, project records, insurance requirements, and roles of the various project participants should be evaluated promptly to determine whether third-party practice is appropriate within the time permitted by CPLR § 1007.
