A co-agent agreement, done before the introduction.

Legally, no specific statute forces two agents to sign a co-broking contract — but if you want the commission split, exclusivity and client-protection terms to be enforceable, you need a written agreement. Thailand has no real estate licensing regulator to appeal to, and a verbal split is nearly impossible to prove if a listing agent closes direct with your introduced client. A short, specific written contract signed before the introduction is the only practical protection either side has.

There's no requirement for Thai, but co-broking in Thailand very often pairs a Thai listing agency with a foreign-facing agent, and Thai courts operate in Thai. A single bilingual Thai–English document, with both versions side by side and an agreed prevailing language, means both agents read the same terms and there's no translation gap to argue over if the split is ever disputed.

A 50/50 split between the listing-side agent and the client-side (buying or renting) agent is the most common arrangement, though splits shift toward whichever side did more of the work — sourcing a hard-to-find listing, or bringing a serious, ready buyer. There's no fixed rule, which is exactly why the split needs to be written down and agreed before the introduction rather than negotiated after a deal closes. The Real Estate Commission Calculator can help both sides model the numbers before you draft the agreement.

A protection period is the window of time after a client is introduced during which that introduction still earns the introducing agent commission, even if the deal doesn't close right away. Thai property deals — especially with foreign buyers arranging fund transfers — can drag on for months. Without a protection clause, a listing agent could wait out an informal arrangement and close direct once the introducing agent's involvement is easy to forget. Thirty to ninety days is a common range, but the exact period should be agreed and written into the agreement, not assumed.

Without a written agreement, liability is genuinely unclear — Thai contract law will look at whatever evidence exists, which for a verbal arrangement is often just messages and memory. A written co-agent agreement should state each side's responsibilities (who handles viewings, negotiation, paperwork), what happens if the client walks away for reasons unrelated to either agent, and how a disagreement over the split gets resolved. Spelling this out before the deal, not after, is what actually prevents the dispute rather than just documenting it.

Either. Many co-agent relationships start with a single-listing agreement to test the working relationship, then move to a broader arrangement covering an agency's full inventory once trust is established. The Co-Agent Agreement Generator lets you scope the agreement to one specific listing or state that it applies to a defined category of properties — just be explicit about the scope, since an agreement written for "this listing" won't protect an introduction made against a different one.

The listing agent's co-broking authority should trace back to what the owner actually agreed to. An exclusive listing agreement with the owner may or may not permit sharing the listing with other agents — some exclusives explicitly allow co-broking with a set split, others reserve it to the listing agent alone. Before signing a co-agent agreement, the introducing agent should confirm the listing agent actually has the authority to co-broke, rather than assuming a listing they found online is open to any agent who brings a buyer.

No. A co-agent agreement is strictly between the two agents (or their agencies) and governs how they cooperate and split commission — it doesn't touch the listing agreement between the listing agent and the property owner, nor the eventual sale and purchase or lease agreement between the owner and the client. All three documents can, and usually do, exist alongside each other for the same transaction, each covering a different relationship.

Yes. The same disputes — who introduced the client first, how the split works, what protection period applies — happen just as often between two agents at the same agency as between two different companies. A written internal co-agent agreement is a normal and useful practice for agencies that want a consistent, fair process for staff who cooperate on cross-team deals, rather than leaving it to whoever manages to make the loudest claim after a deal closes.
