Broker Commission Disputes in New York Commercial Real Estate: Procuring Cause, Licensing, and Litigation Strategy

You're a commercial broker who spent eight months walking a hedge fund through every available Class A floor in Midtown. You introduced them to your client's Park Avenue tower, ran the tours, drafted the term sheet — and then the landlord cut you out and closed the lease through an in-house leasing agent. The commission you were counting on, somewhere north of $400,000, isn't coming. Broker commission disputes in New York commercial real estate happen exactly like this, and the rules that decide who gets paid are stricter and more particular than most participants realize.

On the other side of the table, owners and developers regularly get hit with commission demands from brokers they barely remember meeting — sometimes a year or more after a deal closes. Both sides need to understand the same playbook. At Yassi Law, we litigate broker commission disputes in New York from Manhattan office leases to Long Island industrial sales, and the patterns are remarkably consistent.

When can a New York commercial real estate broker sue for an unpaid commission?

A broker can sue for a commission in New York only if she was duly licensed at the time the services were rendered and there was an agreement — express or implied — to pay her. Both pieces matter, and missing either one is fatal.

The licensing requirement comes from Real Property Law § 442-d, which bars any action to recover compensation for services as a real estate broker or salesperson unless the plaintiff was a duly licensed broker on the date the cause of action arose. Courts apply this strictly. If you were operating under an expired license, or your sponsoring broker's license had lapsed, you can lose a meritorious case at the pleading stage. The New York Department of State licenses tens of thousands of real estate brokers and salespersons, and verifying the status of every individual and entity in the commission chain is one of the first things experienced commercial litigators do.

The agreement requirement is more flexible than people think. Real estate brokerage contracts in New York generally do not have to be in writing. General Obligations Law § 5-701(a)(10) — the statute of frauds provision that catches business-opportunity finders and intermediaries — expressly carves out licensed real estate brokers. That means an oral commission deal can be enforceable, and a course of dealing can create an implied contract. Owners who think a handshake doesn't count are often surprised when a broker walks into court with emails, tour sheets, and a cooperating-broker confirmation and survives a motion to dismiss.

Under established New York law, a broker has earned her fee when she produces a buyer ready, willing, and able to purchase on the seller's terms. Closing is not required. If the seller walks away after that point, the commission is still owed.

What does it take to prove you were the “ procuring cause” of a deal?

You have to show a direct and proximate link between your introduction of the buyer and the consummation of the transaction. Procuring cause is the doctrine that decides who actually earned the commission when more than one broker has touched a deal — and in NYC commercial real estate, that's most deals.

The procuring cause analysis is fact-intensive. New York courts look at who first introduced the buyer to the property, who provided the buyer with material information, who participated in negotiations, and whether the broker was active throughout — or whether the broker abandoned the deal and someone else picked it up months later on different terms. A broker who simply hands over a name and disappears for six months while another broker closes a restructured transaction usually loses. A broker who runs tours, prepares letters of intent, and shepherds the buyer through diligence usually wins, even if she isn't in the room at signing.

Most parties miss that procuring cause does not require the broker to be present at closing or even to be the one who finalized the price. What it requires is that the broker set in motion the chain of events that led, without significant break, to the deal that ultimately closed. When a deal is restructured — say, a sale becomes a ground lease, or a buyer assigns rights to an affiliate — careful litigation often turns on whether the closed transaction is the same deal the broker originated or something materially new.

How do exclusive listing agreements change broker commission disputes?

Exclusive listings shift the risk dramatically in the broker's favor, but only if the contract language is precise. There are two very different types of exclusive arrangements, and they produce different outcomes in commission litigation.

An exclusive right to sell entitles the broker to a commission no matter who finds the buyer — even if the owner finds the buyer herself, walking in off the street. An exclusive agency bars the owner from using a different broker, but the owner can still close a deal with a buyer she found independently and pay nothing. Experienced commercial litigators watch for the precise wording of the listing because owners and brokers often use the terms interchangeably in conversation, but the difference can be hundreds of thousands of dollars when the deal closes.

Two other clauses matter constantly in commercial litigation over commissions. The first is a tail or extension provision — the protected-buyer clause — which gives the broker a commission if a buyer she introduced during the listing period closes within a defined window after the listing expires. Tail periods commonly run 90, 180, or 365 days. The second is a registration requirement, which obligates the broker to identify protected buyers in writing before expiration. If your tail clause requires a written buyer list and you didn't send one, the clause won't save you.

What defenses can a seller or landlord raise against a commission claim?

Owners have a real toolkit, and the strongest defenses are usually the ones that target a specific element of the broker's prima facie case rather than going to credibility.

The most powerful defense is licensing. If the broker — or the individual salesperson who actually did the work — was not licensed when the services were performed, RPL § 442-d ends the case. The second is “not ready, willing, and able” — the buyer the broker produced was unable to perform, lacked financing, or imposed terms the seller never agreed to. A signed term sheet doesn't always equal a ready, willing, and able buyer; due-diligence walkaways and financing-contingency failures both create real openings for owners.

The third major defense is the absence of an agreement. When the owner never signed a listing, never countersigned a commission letter, and never expressly agreed to pay, the broker has to fall back on an implied contract or quantum meruit — both fact-intensive theories that don't survive every summary judgment motion under CPLR § 3212. The fourth is failure of a condition. Many commission agreements say the fee is “due upon closing” or “earned only if the lease is fully executed.” If the parties drafted a condition precedent, New York courts enforce it, and a broker who relies solely on the common-law ready-willing-and-able doctrine will lose to clear contractual language making closing a condition.

A fifth defense, used carefully, is procuring-cause break — the argument that even if the broker did introduce the buyer, the deal that closed was a new transaction after an abandonment. Owners who change material terms, change parties, or close with a different entity months later sometimes have a credible argument that the broker's chain of causation snapped.

How should you litigate or settle a broker commission dispute in NYC courts?

The right venue and the right early motion can change the economics of a broker commission dispute more than anything else. Most of these cases land in New York County Supreme Court because that's where the property or the brokerage is located, with Kings, Queens, Nassau, and Suffolk Supreme handling the rest. Commissions that clear the dollar threshold and meet the subject-matter criteria for the Commercial Division belong there, where you'll get a judge who handles complex business cases all day.

Three procedural moves come up repeatedly. The first is an expedited discovery push to get the deal documents — the closing binder, the lease, the broker registration emails, the internal correspondence between in-house leasing and outside brokers. These cases are won and lost on documents, not testimony. The second is a targeted summary judgment motion. When the listing agreement is unambiguous and licensing is clean, brokers can sometimes win commission on summary judgment without a trial. When the agreement is missing or the procuring-cause chain is broken, owners can knock the case out the same way.

The third move is collection planning. A broker who wins a $750,000 commission judgment against an owner who has already refinanced and moved sale proceeds offshore has won nothing. In the right facts — typically where there's evidence the defendant is dissipating assets — prejudgment attachment under CPLR § 6201 can freeze property before judgment. And when an owner is preparing to close a sale that will leave nothing behind for the broker, a preliminary injunction or TRO may be available to protect specific proceeds.

ADR is the other strategic decision. Many brokerage agreements — particularly REBNY co-brokerage forms and large national brokerage standard contracts — contain arbitration clauses. Commercial arbitration through the American Arbitration Association can be faster than Supreme Court, but you give up some procedural tools, and arbitrator selection matters enormously. If your dispute is going to arbitration, our guide to selecting an AAA arbitrator is worth reading before you strike names off the list.

For brokers and owners deciding whether to fight or settle, the realistic numbers usually come into focus once both sides see the documents. Brokers with strong written agreements and clean procuring-cause facts often settle for 70–90% of the disputed commission. Brokers relying on oral agreements and disputed causation often settle for far less. Owners facing exclusive-right-to-sell agreements with airtight tail clauses tend to pay close to face value because they have no real defense. Choosing experienced commercial litigation counsel who has tried these cases — not just papered them — is what separates a good outcome from a forced settlement.

Frequently Asked Questions

Do broker commission agreements need to be in writing in New York?

No. New York's statute of frauds in GOL § 5-701(a)(10) excludes licensed real estate brokers, so an oral or implied agreement to pay a real estate commission is generally enforceable. That said, written agreements eliminate enormous amounts of litigation risk, and any commercial broker who works on a handshake is taking on unnecessary exposure.

What is the statute of limitations on a broker commission claim in New York?

Most broker commission claims sound in contract and are subject to the six-year statute of limitations under CPLR § 213(2). The clock generally starts when the commission becomes due — often when the deal closes or, under New York's ready-willing-and-able doctrine, when the broker has produced a buyer prepared to purchase on the seller's terms, even if closing never occurs.

Can an unlicensed person collect a finder's fee for a NYC commercial real estate deal?

Generally no. RPL § 442-d bars an unlicensed person from suing for compensation for services that constitute real estate brokerage, and courts construe “brokerage services” broadly enough to swallow most finder's-fee arrangements involving the negotiation or procurement of a real estate transaction. Calling yourself a “consultant” doesn't avoid the licensing requirement when the actual work was brokering.

What happens if the deal closes months after the listing agreement expires?

It depends on whether the listing had a tail or protected-buyer clause and whether the broker complied with its conditions. A well-drafted exclusive listing typically gives the broker a defined window — often 90 to 365 days — to claim commission on buyers she introduced during the term, sometimes conditioned on registering those buyers in writing before expiration.

The Bottom Line

Broker commission disputes in New York commercial real estate turn on three questions: was the broker licensed, was there an agreement, and was the broker the procuring cause of the deal that actually closed? Whether you're the broker chasing an unpaid fee or the owner facing a commission demand, the contract language and the document trail will determine the outcome long before anyone takes the witness stand.
