The State-Line Trap: Challenges with the M&A Broker Exemption

You have worked the deal for nine months. The seller is in Colorado, the buyer is a private equity group out of Chicago, and the deal is a stock purchase with a slice of rollover equity. Diligence is done, your success fee is papered, and your firm sits squarely inside the 2023 federal M&A broker exemption.

Then, three days before closing, the buyer’s counsel sends an email raising a “small compliance question” — confirming your firm’s broker-dealer registration status in Illinois. The tone is polite. The implication is not.

That is the State-Line Trap. The question her lawyer is really asking is whether anyone has to pay you at all.

For a generation of business brokers and M&A advisors, the codification of Section 15(b)(13) of the Securities Exchange Act felt like a regulatory finish line. It is not. The gap between the federal answer and the state answer can be where fee disputes live.

What the Federal Exemption Solved — And What It Did Not

In December 2022, Congress amended the Exchange Act to create a binding federal exemption for qualifying M&A brokers, effective March 29, 2023 (Cornell LII, 2023). To qualify, the transaction must involve an “eligible privately held company” — generally one with prior-year EBITDA under $25 million or revenues under $250 million — and the buyer must reasonably be expected to control and actively operate the business after closing (Nelson Mullins, 2023). That replaced years of reliance on a 2014 SEC staff no-action letter with a statute.

But the statute is narrow in two ways. First, it is conditional. The exemption disappears if the broker has custody of funds or securities, can bind a party, provides debt or equity financing for the buyer, facilitates a sale to a passive buyer, deals in a public-company security (including a public company carve out), or violates any of several other excluded-activity rules (Cornell LII, 2023).

Second — and this is the part too many advisors miss — Section 15(b)(13) does not preempt state law. Congress preserved state authority over broker-dealer activity inside state borders (Nelson Mullins, 2023). Federal comfort does not equal state-law safety.

The Patchwork Begins the Moment a Deal Crosses a Border

State “blue sky” laws are fiercely independent. The North American Securities Administrators Association adopted an updated Model Rule in May 2024 to align state-level M&A relief with the new federal exemption (Transworld M&A, 2024), but a model rule is just a model. According to a list maintained by the IBBA, roughly 23 states have adopted some form of M&A-specific exemption (IBBA, 2025) — leaving close to half the country without a clear safe harbor. Among adopting states, the language is not identical, size thresholds do not always match the federal rule, and notice-filing requirements vary.

And almost no deal is single-state anymore. A seller may be organized in Colorado, operate in Arizona, and own real estate in Texas. The buyer may be a search fund in California backed by New York capital. A broker can enter a single mandate and create touchpoints with several state regimes without realizing it – simply sending out deal teasers and other marketing materials may create a nexus with a particular state. “The company is here” is usually the wrong starting point; the better question is where the transaction activity, the parties, and the compensation structure actually connect to state law.

It Is Not Only a Securities Question

The State-Line Trap is not just a blue sky problem. In several states, the sale of a business overlaps with real-estate licensing rules that can sweep in transactions feeling nothing like property brokerage.

In Florida, state law defines “real estate” broadly enough to include business enterprises, so brokering the sale of a business generally requires a Florida real estate license, in the absence of FINRA registration (EPGD Business Law, 2023).
In California, business-broker activity is typically conducted by a licensed real estate broker or a FINRA-registered broker-dealer (BizBuySell, n.d.).
In Texas, there is no standalone business-broker license, but a real estate license is generally required to collect a commission whenever a transaction includes real estate or a lease assignment, in the absence of FINRA registration (TABB, n.d.).

These rules sit alongside state securities law, not underneath it. An advisor can satisfy the federal M&A broker exemption, satisfy a state’s M&A securities exemption, and still have a real-estate licensing problem in the state where the business real estate — or the lease — sits.

Why the Trap Springs At or After Closing

Few advisors lose sleep over this while a deal is live. Everyone is rowing the same direction, and no one wants to derail momentum with a licensing debate. That changes the moment the wire is about to hit.

Sellers and counsel sometimes look harder at the largest line items on the closing statement — including the success fee. When an earn-out underperforms, parties look for leverage. And when a deal produces litigation, opposing counsel will examine every premise of every contract — including the advisor’s authority to charge a fee in the first place.

That is when the engagement letter becomes a target. Section 29(b) of the Exchange Act provides that contracts made in violation of the Act “shall be void,” and state blue sky laws contain analogous rescission provisions (San Diego County Bar Association, 2015). If a court determines the advisor needed to be registered in a relevant state and was not, the engagement letter may be voidable, and even fees already paid can be subject to clawback.

The usual fallback — quantum meruit — is not a reliable parachute. Courts are often reluctant to award equitable recovery for services a statute treats as unlawfully performed without the required registration (San Diego County Bar Association, 2015). The danger is not that every deal creates a registration problem; it is that the question is easy to ignore until there is a dispute, and by then the advisor’s leverage is gone.

Better Questions to Ask Before You Engage a New Client

The safe response is not panic. It is better intake. Before accepting a mandate, run through a few unglamorous questions:

Where are the seller, the likely buyer universe, and the likely sources of capital located?
In which states will teasers, CIMs, and outreach actually be sent?
Is consideration likely to be all cash at closing, or does it include rollover equity, a seller note notes, or an earn out?
Does the deal involve owned real estate, a lease assignment, or licensed premises?
If a state connected to the deal has its own M&A exemption, does this transaction actually fit it — including any size thresholds, notice filings, or compensation rules?

Those questions will not answer everything, but they will usually tell you whether you are in a routine lane or walking toward a state-line problem.

Three Paths Through

Once the questions are answered, the response is a structural choice. Advisors who do M&A work tend to fall into one of three lanes.

The first is staying inside the federal exemption on deals that genuinely fit it — single-state, eligible privately held companies, with no real estate triggering a state license. Section 15(b)(13) was built for these deals, and for many Main Street brokers it is enough. The discipline is making sure each deal really fits before relying on it.

The second is state-by-state compliance: maintaining real estate licenses where required, making M&A notice filings where required, and tracking state exemption conditions deal by deal. This works, but it scales poorly. Every new state becomes another item on the checklist, and a missed filing can be the same problem as no filing.

The third is registering as, or affiliating with, a FINRA-member broker-dealer. This is the most comprehensive path because it does not try to dodge the state-line question — it answers it. A FINRA-member firm registers with the SEC on Form BD and with each state where it does business through the Central Registration Depository; its M&A representatives register through Form U4 in the same system. Most states accept registration through CRD, though a handful, including California, require additional direct filings (Kroll, 2024). A properly registered firm and its reps can then transact deals of all types across state lines without depending on whether a particular state has adopted the federal exemption — the licensing requirement has been satisfied directly, not navigated around.

None of these lanes is right for everyone. Many brokers spend their careers in lane one. Others graduate from lane two to lane three as their deals grow larger, more complex, and occasionally fall outside of the federal exemption (e.g. growth equity and minority recapitalizations). The mistake is not picking the wrong lane — it is operating as if the choice has not been made.

The Bottom Line for Working Brokers

The federal M&A broker exemption was a real improvement. It just did not answer all the questions.

Treat Section 15(b)(13) as one part of the analysis, not the whole analysis. If deal marketing efforts and/or the transaction parties cross state borders, and/or a deal involves real estate, state law deserves attention at the front end — and your firm’s licensing posture should be a deliberate choice, not the byproduct of having read a headline about a federal exemption.

The best time to solve the state-line problem is when everyone still wants the deal. The worst time is when the deal is done, the leverage is gone, and your fee has become the next item someone wants to renegotiate.
