An unlicensed NYC home improvement contractor cannot sue you for payment and cannot enforce a mechanic's lien against your home, even if the work was actually performed. This is well-settled law in New York, repeatedly reaffirmed by the Appellate Division, most recently in 2024. The bar applies to kitchens, bathrooms, and full gut renovations alike, and it reaches both general contractors and subcontractors. If you're staring down a demand letter, a summons, or a lien, you ha

You bought a Midtown dental practice for $2.4 million based on three years of patient-visit reports and revenue summaries the seller swore were pulled straight from the practice-management software. Four months after closing, you discover the reports were doctored. Half the "active" patients hadn't been in the chair in five years. The hygienist tells you the seller spent the last two years padding the numbers to make the practice look sellable. You're sitting on a loan you ca

You're the general contractor on a $6.4 million adaptive reuse of a Long Island City warehouse. The owner promised a permit-ready site by March. The permits didn't drop until August, your steel supplier ran into tariff-driven backorders, and now you're staring at five extra months of trailer rentals, superintendent salaries, and escalated concrete pricing. When you ask the owner to pay for the delay, they point to a single sentence buried in Article 8: "Contractor shall not b

Updated October 22, 2026 Your best distributor just walked away from a five-year supply contract with your Long Island City manufacturing business. When you press for a reason, you learn a competitor flew the distributor's owner to a resort in Miami, offered richer terms, and promised to cover any breach-of-contract damages. You have a signed agreement, a lost customer, and a rival who knew exactly what they were doing. This is the classic setup for a tortious interference wi

Your company spent eighteen months courting a Midtown food distributor and finally landed a five-year exclusive supply agreement. The ink was barely dry when a competitor swooped in — offering the distributor a sweetheart side deal, indemnity against any breach exposure, and a promise to cover liquidated damages. Three weeks later, your distributor terminates for “convenience.” That's not just hard-nosed selling. In New York, orchestrating someone else's breach can be a busin

You hired a contractor last spring to gut-renovate the parlor floor of your Prospect Heights brownstone. The kitchen is half-finished, the invoices are stacking up, and now the contractor is threatening to sue you for the $220,000 he says you still owe. Then you check the New York City license database and find nothing under his name. If you're dealing with an unlicensed home improvement contractor in NYC, the leverage in the dispute may have just shifted dramatically — and n

Your top account executive resigned on a Tuesday. By the following Monday, she'd joined a competitor two blocks north on Sixth Avenue. Within 90 days, four of your enterprise clients — collectively worth $3.8 million in annual revenue — terminated their three-year contracts and moved to her new employer. That's not just an unlucky quarter. That may be tortious interference with contract in New York — and it's one of the most powerful business torts available to companies oper

Your general contractor just handed you a certificate of substantial completion for the $3.2 million gut renovation of your Tribeca loft. The kitchen is functional, but the primary bath still leaks, the HVAC won't hold temperature above the third floor, and the elevator hasn't passed its final DOB inspection. The GC wants final payment and release of the $320,000 retainage. You think the job isn't done. Substantial completion in New York construction contracts is one of the m

Your top salesperson resigns on a Friday and, by Wednesday, three of your biggest Manhattan clients call to cancel their contracts. You dig in and learn the salesperson's new employer — a direct competitor across town — knew about your written agreements, saw copies of your pricing, and told your clients you were about to lose a key vendor and couldn't perform. You've got signed contracts. You've got damages. And you've got a competitor who deliberately blew up your book of b

You're in the middle of a $1.4 million gut renovation of a Cobble Hill brownstone. The relationship with your general contractor has collapsed over a change order dispute, and you've withheld the final $180,000 until the punch list is finished. Two weeks later, a $1.1 million mechanic's lien lands on your title report — six times what you actually owe, padded with fictional "lost profits," phantom overhead, and materials that never showed up on site. You feel cornered. You sh

You spent eight months negotiating a $3.8 million distribution contract with a Long Island manufacturer. The ink is dry, shipments are scheduled, and your sales team is celebrating. Then a competitor calls your buyer's CEO, offers a below-cost sweetheart price, and hints — falsely — that your certifications are about to be pulled. Two days later, your buyer cancels the deal "for cause."That's not aggressive competition. In New York, deliberately blowing up someone else's sign

You spent 14 months and $1.8 million turning a Carroll Gardens brownstone into your dream home. The GC handed you the keys in March. By August, the third-floor bathroom is leaking into the parlor ceiling, hairline cracks are spidering across the freshly plastered walls, and the "bespoke" white oak floors are cupping in six rooms. The contractor stopped returning calls two weeks ago. This is when most owners start asking about construction defect claims in New York — and most

Updated October 22, 2026 You own a mixed-use building in Brooklyn. You hired a general contractor to repoint the facade, collected a certificate of insurance, and filed it away. Then a subcontractor's worker fell from a scaffold, got seriously hurt, and sued you, not his employer. You sent the lawsuit to your own insurance company and expected a defense. Instead, you got a letter saying your policy excludes exactly this kind of claim. That letter is the action-over exclusion

You closed a $4 million supply deal with a Long Island distributor last spring. Three weeks before the first shipment, a competitor calls your distributor, offers slightly better terms, and hints that you're overleveraged. The distributor backs out. Your competitor lands the account. This is the exact scenario tortious interference with contract in New York was designed to punish, and if you can prove the elements, you can recover the profits you lost when your deal collapsed

You're an owner three months into a $2.4 million gut renovation of a Cobble Hill townhouse. The GC has blown through two milestone dates, deliveries stopped last week, and the site super hasn't shown up since Monday. You want the contractor gone. Or maybe you're on the other side — you're the contractor, the owner hasn't paid a $340,000 requisition for 82 days, and the architect keeps rejecting perfectly conforming work. You want to walk off the job. Terminating a constructio

Your top account manager just resigned to join a rival firm across the East River. Within two weeks, three of your biggest Manhattan clients — each locked into multi-year service agreements with your company — have suddenly "terminated for convenience." You dig deeper and learn your competitor knew about those contracts, promised those clients indemnity if they were sued for breaching, and even offered to pay their exit fees. In New York, that's not just aggressive competitio

Updated October 21, 2026 You wired $150,000 to a home improvement contractor in April for a full renovation of your Astoria two-family. He tore out the kitchen, framed one bathroom wall, then stopped answering the phone. When you check your bank statement, that deposit is gone, and so is he. Most NYC homeowners assume a stolen deposit is a lost cause, so they call their bank, file a police report, and give up. It isn't a lost cause. New York's home improvement deposit escrow

You spent eighteen months negotiating a $3.8 million supply contract with a Long Island distributor. The ink was barely dry when a competitor from Queens started calling your customer, spreading rumors about your credit, and offering below-cost pricing to blow up the deal. Two weeks later, your customer terminates. Your revenue projections collapse, your bank line tightens, and the competitor walks away with the business you built. This is where a claim for tortious interfere

Updated October 22, 2026 You paid a contractor $180,000 to gut-renovate the parlor floor of your Park Slope brownstone. Work started in March. By June, the framing was up, drywall was half-hung, and the crew stopped showing up. Phone calls go to voicemail. Text messages go unread. Meanwhile, two subcontractors just filed mechanic's liens against your home, and your family is living in a construction zone with no end in sight. Contractor abandonment in New York is one of the m

Updated October 22, 2026 You spent eight months negotiating a $4.2 million distribution agreement with a Long Island City manufacturer. Contracts were signed on a Tuesday. The following Monday, your competitor met with the manufacturer's owner, showed him a spreadsheet full of half-truths about your credit history, and by Wednesday the manufacturer sent you a termination letter. That's not just bad luck. It may be tortious interference with contract in New York, one of the mo
