Commission Agreement
Commission. It's the reason you're in this business, and yet it's one of the most under-documented parts of a California transaction. The Commission Agreement (CBC) is the form that puts the compensation arrangement in writing between cooperating brokers, so there's no confusion about who's paying, how much, and when. Whether the seller is offering a buyer's agent commission, the buyer is covering it out of pocket, or you're working out a split, this document is what makes the whole thing official.
Why This Document Matters
Real talk: the days of assuming the listing side will always cover buyer's agent compensation are over. Post-NAR settlement, commission arrangements are getting more scrutiny than ever, and California agents need documentation that's airtight. The CBC exists to spell out exactly what the buyer's broker is getting paid and where that money is coming from.
Without it, you're relying on handshake agreements and assumptions. That's a liability problem, a broker problem, and frankly a you problem. If a deal closes and there's a dispute over commission, the first thing anyone asks for is what's in writing. This form is your answer to that question.
It also connects directly to your Buyer Representation and Broker Compensation Agreement. The BRBC establishes what the buyer agreed to pay their agent. The CBC documents what's actually being offered or negotiated in the transaction. They need to be consistent with each other, and they need to be consistent with the listing agreement on the other side. If those numbers don't line up, you've got a problem to sort out before you get anywhere near closing.
How It Works
The CBC is typically prepared and submitted with the offer or as part of the offer package. It documents the commission structure that the buyer's broker expects to receive and identifies the source of that payment. That source could be the seller (via the listing agreement), the buyer directly, or some combination of both.
When a listing already offers buyer's broker compensation, the CBC confirms the amount and the acceptance of those terms. When no seller-side compensation is offered or the amount is less than what the buyer agreed to pay their agent, the CBC can document a request for the seller to cover the difference, or it can formalize that the buyer will be covering the shortfall per their BRBC.
The California Association of Realtors developed this form in response to the shifting compensation landscape, and it's become a standard part of offer packages in transactions where commission terms need to be clearly documented between the two brokerages.
Key Sections Explained
Commission Amount or Percentage. This is the total compensation the buyer's broker is expecting to receive. It can be expressed as a flat dollar amount or a percentage of the purchase price. Be specific. Vague language here causes real problems later.
Source of Payment. Who is actually writing the check? The seller, the buyer, or both? This section breaks down whether the compensation is coming from the listing side's offer of compensation, directly from the buyer, or split between the two. It has to match what's in your BRBC and what the listing is offering.
Timing of Payment. Commission is earned at closing, but this section spells out the exact conditions under which payment is made. It also addresses scenarios where the transaction might fall apart before recording.
Conditions for Earning Commission. This covers what needs to happen for the commission to be considered earned. Typically that means a successfully recorded sale, but the specifics matter, especially if there's any chance the deal might cancel.
Common Mistakes to Avoid
Not getting it in writing is the biggest one. Verbal agreements about commission don't hold up, and relying on an email chain instead of an actual signed form is asking for a headache. Use the CBC.
Inconsistency across documents is another common issue. If your BRBC says the buyer is paying 2.5% and the CBC says the seller is covering 2%, you've created a gap that someone has to resolve before close. That someone will probably be you, and probably at the worst possible time. Double-check that your numbers match across all agreements. Deadline management isn't just about contingency dates. It includes catching these discrepancies before they become deal-killers.
Being vague about who is paying is another one. "Seller will pay buyer's agent commission" sounds clear enough until the listing broker says they never agreed to that amount. Specificity matters.
Finally, not addressing what happens if the transaction falls through. If the deal cancels, does anyone get paid? Under what circumstances? The CBC should speak to this, or at minimum, your BRBC should. Don't leave it to assumption.

Pro Tips from a TC
Always get the CBC signed before or at the time of offer submission. Trying to circle back on commission documentation after you're already in contract is awkward, sometimes contentious, and occasionally impossible if the other side decides to push back.
Review the listing's offer of compensation before you write anything into the CBC. Some listings offer a specific dollar amount, some offer a percentage, and some offer nothing. Know what you're working with so your form reflects reality.
Cross-reference the CBC against both the BRBC and the listing agreement. All three documents should tell the same story about who's getting paid and how much. If they don't, fix it now. A transaction compliance review catches exactly this kind of thing.
If the buyer is covering any portion of the commission, make sure they understand this is reflected in their BRBC and that they're financially prepared for it. This isn't a surprise you want to spring at the signing table.

Frequently Asked Questions
Q: Is the Commission Agreement required on every transaction?
No, it's situational. The CBC is used when there's a commission arrangement between cooperating brokers that needs to be documented, particularly when the compensation structure isn't already fully addressed by an existing offer of compensation in the listing. If the listing clearly spells out buyer's broker compensation and the buyer's broker accepts those terms, the CBC is the vehicle for making that agreement official. If you're uncertain whether it applies to a specific transaction, check with your broker.
Q: What's the difference between the CBC and the BRBC?
The BRBC is the agreement between you and your buyer client. It establishes that the buyer has retained you as their agent and documents what they've agreed to pay you for representation. The CBC is the agreement between the buyer's brokerage and the seller's brokerage (or a direct arrangement with the buyer) that documents the actual commission being paid in the transaction. One is a client agreement, the other is a broker-to-broker compensation agreement. You need both, and they need to be consistent.
Q: What happens to the commission if the deal falls through?
It depends on the terms in your CBC and BRBC. In most California transactions, commission is earned at close of escrow, meaning a canceled deal typically means no commission. However, there are situations where a buyer's bad-faith cancellation or a breach of contract could create an argument for compensation. Your CBC should address this clearly, and if you're dealing with a complex situation, it's worth a conversation with your broker or legal counsel. The California Department of Real Estate has guidance on broker compensation disputes that's worth knowing.
