If you manage property, oversee construction contracts, or defend premises liability claims in New York, 2026 brought a rule change that cannot be ignored. The AVOID Act—effective April 18, 2026—rewired how and when defendants must bring third parties into a lawsuit. Under amended provisions of New York’s Civil Practice Law & Rules (CPLR), specifically CPLR § 1007(b), third-party complaints must now be filed within 90 days of serving the initial answer. For slip-and-fall cases involving multiple responsible parties—property owners, maintenance contractors, general contractors, and property management firms—the new york impleader deadline avoid act slip fall liability 2026 framework means that missing a cutoff no longer results in a judicial scolding. It results in the permanent loss of the right to bring a third-party claim.
What the AVOID Act Changed About Impleader in New York
Impleader is the procedural mechanism by which a defendant brings an additional party—called a third-party defendant—into existing litigation, typically to seek indemnification or contribution. Before April 18, 2026, New York courts applied a discretionary balancing test when evaluating late impleader motions. Judges weighed factors such as prejudice to existing parties, the stage of litigation, and the strength of the proposed third-party claim. Defense counsel learned to exploit this flexibility, filing impleader motions late in discovery with reasonable hopes of judicial approval if the delay could be justified.
The AVOID Act ended that era. Under CPLR § 1007(b), effective April 18, 2026, defendants must file third-party complaints within 90 days of serving the initial answer. Once that deadline passes, the right to implead is forfeited—full stop. Courts no longer have authority to grant relief based on equitable arguments about discovery complexity or counsel’s workload. This is the core of what practitioners in the premises and construction liability space have described as a fundamental paradigm shift: the impleader right is now a use-it-or-lose-it entitlement with a hard expiration date tied directly to a specific filing event.
