Business broker confidentiality: what you may share when referring a client

A business broker's confidentiality obligations come mainly from the listing agreement, agency duties under state law and any association code, and they usually bar disclosing a client's identity, sale plans or files without consent. Before referring a client anywhere, get the owner's written permission, share only basic fit information, and let the owner apply directly.

The short answer: written permission, then the minimum

A business broker's confidentiality obligations usually forbid disclosing a client's identity, sale plans or files to anyone outside the purpose of the engagement unless the owner agrees. Those duties come mostly from private documents and professional norms rather than one statute: the listing or engagement agreement, the agency duties your state recognizes, and the code of any association you belong to.

A data-licensing introduction sits outside a sale mandate. So referring a listed client to SourceX, or to anyone else, follows a three-part rule: get the owner's written permission, share only basic fit information, and let the owner apply directly wherever possible.

Where do a broker's confidentiality duties come from?

Source	What it typically covers	What to check before a referral
Listing or engagement agreement	Confidentiality of the client's identity and information, permitted uses, survival after termination	The use clause: is anything beyond marketing the business for sale allowed?
Agency duties under state law	Loyalty and confidentiality where you act as the client's agent; rules vary by state	Your state's licensing law and board guidance, especially where business brokerage falls under real estate licensing
Association code of ethics	May address confidentiality and disclosure of compensation, if you belong to one	The current text of your own association's code
Buyer NDAs	What prospective buyers may do with the seller's information	They bind buyers, not you, and authorize no new disclosure
Co-brokerage or referral agreements	Duties to another broker and that broker's client	Whether the client is yours to introduce at all

The listing agreement usually matters most. Look for three clauses: the definition of confidential information, which often includes the client's identity and the fact of the engagement; the permitted-use clause, which typically limits use to marketing the business for sale; and the survival clause, which says how long the duty lasts after the listing ends.

Can a broker disclose a listing to a third party?

Only within what the client authorized, which in a sale mandate means qualified buyers who have signed an NDA. Telling anyone else that a named business is for sale is a disclosure in its own right and often the most damaging one, because employees, customers, lenders and competitors react to sale news. Blind teasers exist for that reason.

A data-licensing introduction does not need the sale at all. SourceX needs to know whether the company might fit, not that it is listed, so the referral can leave the sale process out entirely. Whether and when to mention it is the owner's call, made with deal counsel. If an LOI has been signed, the buyer's exclusivity terms come first; the page on LOI exclusivity and no-shop clauses explains what to check.

How the duties apply in common broker situations

Situation	What to check	Typical outcome to confirm
Active blind listing, no LOI	Use clause in the listing agreement	Written owner permission; the owner applies with your referral link
Listing under an LOI with exclusivity	No-shop and ordinary-course terms in the LOI	No contact with anyone until deal counsel clears it
Listing expired or withdrawn	Survival clause in the listing agreement	Duties often survive; ask the owner first regardless
You learned about a buyer's own company under its NDA	The buyer's confidentiality agreement	Do not use it; approach the buyer separately, outside the deal
Valuation meeting, no engagement signed	Any NDA you signed and your professional norms	Treat it as confidential and ask before acting
Co-brokered listing	The co-brokerage agreement	Coordinate with the listing broker; the client may not be yours to introduce
Stalled listing, owner weighing options	The same terms as an active listing	Permission, then the minimum; see what brokers can offer when a listing is not selling

The permission-minimum-direct rule

Ask in writing. Email the owner, name SourceX, list exactly what you would share and mention that you may receive a referral reward. Keep the reply in the client file.
Share the minimum. Industry, approximate headcount, years in operation and the names of the main business systems are enough for a fit conversation.
Prefer the owner applying directly. Send your referral link so the owner applies at sourcex.si/apply with your code attached; your credit is preserved and you disclose nothing about the company yourself.
Stop at no. If the owner declines or hesitates, drop it. Do not refer anonymously or drop hints.
Stay out of the records. Never export, upload or describe company data. Rights, de-identification and redaction are agreed between the company and SourceX before any work begins, and nothing is delivered without an executed agreement and the company's authorization.

A permission note can be two sentences, sent by the owner or confirmed by reply:

Before anything is sent, confirm:

The owner's written permission is saved in the client file
The message contains nothing from the CIM, teaser or data room
No financial statements, tax returns, valuation or QoE figures are included
No customer, vendor or employee names appear
Nothing mentions the asking price, buyer interest or an LOI
No screenshots, exports or samples from company systems are attached

What to say to the owner

The introduction email builder can draft a longer version. Raise it only with owners whose companies plausibly fit: a US business that had 50+ full-time employees at peak (contractors excluded), several years of documented operations, the rights to license its records and someone with authority to sign. Many Main Street listings will be too small, which is why the guide to additional revenue streams for business brokers focuses on larger, multi-system clients.

Disclosing your compensation and your status

Partners earn 25% of the eligible platform fees SourceX actually collects from the referred company's licensing deals, capped at $100,000 per referred company, payable only after the buyer pays and SourceX receives its fee. Nothing is earned for the introduction itself, and rewards are not guaranteed. Whether you must disclose the reward to your client depends on your state, your license and any association code, but written disclosure is the safe default.

If you recommend the program publicly, in a newsletter, on LinkedIn or on your website, FTC staff guidance says a connection that would affect how people weigh the recommendation should be disclosed clearly and conspicuously, close to the recommendation. The FTC mandates no specific wording, but a vague label such as affiliate link on its own may not be understood; a plain statement that you are paid for referrals is clearer.

Brokers who rely on the statutory M&A broker exemption for stock sales should note its scope. Exchange Act Section 15(b)(13) covers brokers effecting securities transactions solely in connection with transferring ownership of an eligible privately held company. It is not a general referral exemption and does not address a data-licensing introduction, so ask your own counsel rather than assume your sale-side position answers the question. The comparison of business brokers, M&A advisors and investment bankers covers how securities rules differ by role.

Questions to ask your counsel or licensing board

Does my listing agreement permit any use of client information outside the sale mandate?
Does my state treat business brokerage as real estate brokerage, and does that affect referral compensation or disclosure?
Does my association's code require me to disclose referral compensation to the client?
Which of my confidentiality duties survive an expired or withdrawn listing?
How should I document an owner's permission so it holds up later?

This is general information, not legal, tax or financial advice. Confirm with your own counsel, tax adviser or professional body before acting.

Next step

Send the owner a permission request before anything else. Once you have it, register as a partner, share your referral link and let the owner apply directly. The business broker partner page explains how the program fits alongside a brokerage practice.

Step 1Share your linkSend your personal link to a company you know.
Step 2Company appliesThe company applies itself at /apply.

Common questions

Can I give SourceX a client's name if I share nothing else?

Not without the owner's permission. In many listing agreements the client's identity and the fact of the engagement are confidential in themselves, so a name alone can be a breach. The cleaner route is to send the owner your referral link and let them apply directly; your credit is preserved through the referral code and you disclose nothing yourself.

Does a buyer's NDA let me share seller information with other parties?

No. A buyer NDA restricts what prospective buyers do with the seller's information; it does not widen what the broker may disclose. Your own limits come from the listing agreement, any agency duties under state law and your association's code. Treat the NDA as protection for the seller, not as permission for anyone else.

Do I have to tell the owner I may be paid for the referral?

Check your state's licensing rules, the terms of your license and any association code you follow, because requirements vary. Written disclosure is the safe default whatever they say. It also helps to explain that the reward is a share of SourceX's fee, so it is never deducted from what the company receives, and that it is paid only if a deal completes and the buyer pays.

Do confidentiality duties end when the listing agreement expires?

Often not. Many listing agreements include a survival clause that keeps confidentiality obligations alive for a set period, or indefinitely, after termination, and agency duties under state law may also continue for information learned during the engagement. Read the clause in your own agreement and assume the duty continues until you confirm otherwise.

Should the referral mention that the business is for sale?

There is no need. SourceX assesses fit on size, operating history, data breadth and rights, not on whether the owner is selling. Leaving the sale out protects the listing and keeps the introduction separate from the mandate. The owner can decide later, with deal counsel, whether a sale process affects the timing or terms of any license.

Can I refer a business listed by another broker?

Only with care. If you learned about the company through a co-brokerage arrangement or a buyer-side role, its information may be covered by another broker's agreement or by an NDA you signed. Coordinate with the listing broker, and if the owner is not your client, let the owner decide whether to apply directly rather than passing anything on.
