What Is a Buyer Broker Agreement in California?

If you're buying a home in California in 2026, you'll be asked to sign a buyer-broker agreement before an agent can represent you. This is relatively new — it became mandatory on January 1, 2025 under Assembly Bill 2992 — and a lot of buyers don't fully understand what they're signing or why it matters.

What the agreement does

A buyer-broker agreement is a written contract between you and your real estate agent. It establishes the agent as your representative and spells out the terms of that relationship: what services they'll provide, how much they'll be compensated, how long the agreement lasts, and how either party can end it.

Before this law, agents could represent buyers informally — showing homes, writing offers, and collecting commission at closing without ever putting the terms in writing. The buyer often had no idea what their agent was being paid or what they were entitled to in terms of service.

What it must include

Under AB 2992, your buyer-broker agreement must specify the agent's compensation — the exact amount or percentage they'll earn. It must also describe the services the agent will provide, state when compensation is due, and include an expiration date that cannot exceed three months from signing.

The three-month cap is important. It means you're not locked into a long-term relationship with an agent who isn't delivering. If things aren't working after three months, the agreement expires automatically and you're free to work with someone else.

Why this is actually good for buyers

The old system was opaque. Buyers didn't negotiate commission because they didn't see it — it was buried in the listing agreement between the seller and their agent. Now, you negotiate your agent's compensation directly, in writing, before any work begins. This creates competition among agents and gives you leverage to shop for better rates.

It also means you can compare agents on price and service, not just personality. If one agent charges 2.5% and another charges 1% for the same offer-to-close representation, you can make an informed decision about which one offers better value for your specific situation.

What to watch for before signing

Read the compensation section carefully. Make sure you understand whether the agent expects the seller to pay, whether you're responsible if the seller doesn't offer enough commission, and whether there's a minimum fee regardless of the purchase price.

Check the termination clause. A good agreement lets you cancel with reasonable notice. Be cautious of agreements with cancellation fees or penalties — these can make it expensive to switch agents if the relationship isn't working.

Look at the exclusivity terms. An exclusive agreement means you can't work with other agents during the contract period. A non-exclusive agreement gives you more flexibility but may mean less commitment from the agent. Understand which type you're signing.

The bottom line

The buyer-broker agreement isn't something to be afraid of — it's a tool that protects you by putting everything in writing. The key is to read it carefully, understand the compensation terms, and make sure the service level matches the fee. A 1% agent with a clear, simple agreement and transparent terms is often a better deal than a 2.5% agent with a complex contract full of caveats.
