Co-Broking Rules in Singapore: What Every Property Agent Must Know

Updated: 2 days ago

Co-broking in Singapore means two or more property agents, each representing a different party, working together on one transaction for the benefit of their own clients. The rules come from the Council for Estate Agencies (CEA), and the short version is this: represent only the client who appointed you, agree any commission sharing openly with the other agent, and never block a legitimate co-broking opportunity. If you are new to the industry, our overview of the property agent licence and CEA rules is a good place to see where co-broking fits in your day-to-day compliance.
Read our main guide: Property agent licence Singapore: requirements and steps.
We wrote this guide as a team in ERA’s Preeminent Group, for people considering a property agent career and for newly licensed agents who will meet their first co-broke within weeks of starting.
TL;DR
Co-broking is two agents acting for different parties on the same deal, and CEA describes it as good for both sides because sellers reach more buyers and buyers see more options.
Sharing commission is an agreement between the agents involved. CEA does not set a split percentage, so agree it early and in writing.
You may represent only one party. You cannot collect commission from both sides, and helping the other party with paperwork needs your own client’s consent and a clear statement.
Refusing or obstructing a co-broke has led to fines and suspensions in CEA disciplinary cases, so treat it as a professional duty, not a private matter.
If an arrangement goes wrong, speak to the other agent first, then involve your Key Executive Officer (KEO).

What does co-broking mean in Singapore property transactions?
In plain terms, co-broking happens when the seller’s agent and the buyer’s agent are different people, often from different agencies, and they cooperate to close the deal. The same applies on the rental side, where a landlord’s agent and a tenant’s agent work together.
CEA’s consumer guidance defines co-broking as two or more property agents representing different parties and working together for the benefit of their respective clients. It can involve sharing or receiving part of a commission. CEA also presents the practice as beneficial: sellers get access to a wider pool of potential buyers, and buyers get access to more property options through agents’ networks.
For you as an agent, that has a practical meaning. When another agent’s client wants to view your client’s listing, the sensible and expected response is to cooperate. Your client’s interest is a sale at a good price, and more qualified buyers help that.
A simple example of how it works
Suppose you list a resale HDB flat for a seller. Another agent has a buyer who fits the flat. That agent contacts you, you arrange the viewing, and both of you serve your own clients through to the sale. You act for the seller, the other agent acts for the buyer, and the two of you agree how any commission is shared. Nobody serves both sides.
Which co-broking rules and guidelines apply to agents?
CEA’s Practice Guidelines apply to estate agents and registered salespersons when they conduct estate agency work, and CEA expects every agent to understand and comply with them. Co-broking sits within this framework, alongside the Code of Ethics and Professional Client Care that governs all licensed agents and registered salespersons.
The most recent change many agents ask about came in July 2024. CEA reports that the Singapore Estate Agencies Association (SEAA) Best Practice Guide for Co-broking Commission took effect on 1 July 2024. CEA also reports that, as at February 2025, 70 estate agencies representing 90% of Singapore’s registered salespersons had adopted it.
Mandatory rules versus best practice
It helps to separate two layers:
Binding obligations. Practice Guidelines and the Code of Ethics apply to you as a registered salesperson. A breach can be treated as unsatisfactory professional conduct or professional misconduct.
Industry best practice. The SEAA guide is a best practice guide adopted by agencies. Check with your own agency how it applies to you, and read CEA’s own explanation of it before your first co-broke.
We recommend new agents read the CEA page on the guide in full rather than rely on second-hand summaries, because the details can be updated. Our guide to what the CEA ethics guidelines require covers the wider ethical framework.
How is commission shared between co-broking agents?
The sharing of commission is strictly an agreement between the property agents involved, according to CEA’s guidance for consumers. CEA does not prescribe a split percentage, and neither will we. What matters is that the arrangement is clear before work is done.
There is also a client-side point. CEA says the estate agency agreement should state the agent’s duties, the agreed commission rate and conflict-of-interest declarations, and it encourages clients to sign one before estate agency work begins. Your client’s commission arrangement with you is one thing. Your arrangement with the co-broking agent is another. Keep them separate in your mind and in your paperwork.
What to settle before the viewing
Before you bring a client to another agent’s listing, or accept a co-broking request, confirm these points with the other agent:
Whose client is whose, and which agent represents which party.
How any commission will be shared, and when.
Who handles which tasks, such as viewings, documentation and follow-up.
That the arrangement is recorded in writing, even if only by message or email you can retrieve later.
A short written note avoids most disputes. It also protects both of you if a deal drags on for weeks.
Can an agent act for both sides when co-broking?
No. CEA is clear that co-broking does not permit dual representation: an agent may represent only one party and cannot collect commission from both sides. The CEA guidance adds that an agent may help the other party with paperwork only with the represented client’s consent and an express statement that the agent is not acting for, or charging, the other party.

This is where newer agents get caught. When the other agent is slow, a buyer may ask you to just fill in the forms. That is the moment to stop and check three things: does your own client consent, have you told the other party in clear terms that you do not act for them, and are you collecting nothing from them. Our detailed article on dual representation rules for Singapore agents walks through the scenarios and the scripts.
Comparing the roles side by side
Situation | What you may do | What you must not do |
You represent the seller and another agent represents the buyer | Share information on the listing, arrange viewings, agree commission sharing with the other agent | Act for the buyer or take fees from the buyer |
The other party asks you to help with paperwork | Help only if your own client consents and you state you are not acting for or charging them | Help quietly without consent or without the statement |
Another agent asks to bring a client to your listing | Cooperate and make the property available for viewings | Refuse or obstruct a legitimate co-broking request |
You receive a co-broking fee and a client commission | Be open about both with the people concerned | Conceal either payment |
What do you owe your own client when you co-broke?
Your duties to your client do not shrink because a second agent is involved. If anything, they matter more, because there are more moving parts. CEA says salespersons must explain the meaning and consequences of an estate agency agreement and give clients enough time to read and understand it before deciding.
In a co-broke, that translates into good habits:
Tell your client early that another agent may be involved, and explain why that usually helps them.
Explain how the commission arrangement works from their side, using the estate agency agreement.
Keep representing only your client, even when the other agent is friendly and helpful.
Be honest about anything that could look like a conflict of interest.

What happens if you refuse to co-broke or breach the rules?
CEA treats co-broking breaches as professional conduct matters. Two published cases show how seriously.
In one, CEA disciplined a salesperson with a $14,000 fine and a seven-month suspension for, among other breaches, refusing to co-broke and failing to act fairly and reasonably toward another salesperson. The lesson is that blocking a legitimate co-broke is not just a commercial disagreement.
In another case, a salesperson received a $27,000 financial penalty and a 10-month suspension after concealing receipt of both a tenant commission and a landlord-side co-broking fee. Concealment turned a commission question into a serious disciplinary matter.

You should also know how complaints flow. CEA encourages a complainant to approach the property agency first. If that does not resolve it, the matter may go to CEA’s Dispute Resolution Scheme, where it falls within scope and the prescribed estate agency agreement was signed. CEA can also investigate complaints about the conduct of estate agency work and may take disciplinary or prosecution action where the evidence supports the allegations.
Related rules that often travel with co-broking
Co-broking deals tend to raise other compliance questions at the same time. Referral fees have their own requirements, covered in our guide to referral fee rules for Singapore salespersons. Inducements and advertising are separate areas again. If you are new, it is worth reading all of them once, so that none of these surprises you mid-transaction.
What should you do when a co-broking arrangement goes wrong?
For disagreements between agents, CEA’s guidance for salespersons on managing disputes is straightforward: try to resolve it with the other salesperson first, and consider approaching the co-broking agency’s KEO.
A practical order of steps:
Check your record. Read your written notes or messages on the agreed arrangement.
Speak to the other agent. Most disagreements are misunderstandings about roles or timing.
Tell your own KEO. Your agency has a compliance function for exactly this.
Consider the co-broking agency’s KEO. This is the route CEA names when direct talks fail.
Keep your client informed. Their transaction should not stall because of an argument between agents.
If you think the other agent has broken the rules, CEA’s complaint channels exist for that purpose. Use them on the facts, not on frustration.
What is our view on co-broking at Donny Lee Advisory?
We are Donny Lee Advisory, a team in ERA’s Preeminent Group, led by Donny Lee. Our approach to co-broking is the same as our approach to everything else: structured mentorship, hands-on onboarding and a team culture where compliance is learned early, not after a problem.
The agents who struggle with co-broking are rarely the ones who dislike the rules. They are the ones who were never shown the situation in advance. So we walk new agents through the common scenarios during onboarding: the request to help the other party with forms, the colleague who wants a quick commission split on a handshake, the listing you would rather keep to yourself. Each of them has a clear answer under CEA’s guidelines, and knowing it beforehand takes the pressure out of the moment.
Our team works with Singapore Citizens and Permanent Residents, and we support new and experienced agents through the Sales+ and GRABPro apps and digital training. A client who sees that you co-broke cleanly, explain who acts for whom and document the arrangement is a client who trusts you with the next transaction.
Co-broking is not a favour you do for another agent. It is part of serving your own client well, and CEA’s rules make that clear. — Donny Lee

Frequently asked questions
Is co-broking compulsory in Singapore?
CEA’s Practice Guidelines apply to every registered salesperson, and CEA has disciplined an agent for refusing to co-broke. In practice, you should not refuse or obstruct a legitimate co-broking request on a listing you hold. Check your agency’s own policy and CEA’s current guidance for the details that apply to your situation.
Does CEA set the co-broking commission split?
No. CEA’s consumer guidance says the sharing of commission is strictly an agreement between the agents involved. Agree it early, define each agent’s role, and keep a written record so both of you are clear.
Can I act for the buyer and the seller if I am co-broking?
No. You may represent only one party and cannot collect commission from both sides. You may help the other party with paperwork only if your own client consents and you state expressly that you are not acting for, or charging, that party.
What should I do if the other agent will not follow the agreed arrangement?
Try to resolve it directly with the other salesperson first, then consider approaching the co-broking agency’s KEO, as CEA suggests in its guidance on managing disputes. Keep your client updated throughout.
What are the penalties for breaching co-broking requirements?
CEA has published cases where salespersons received fines and suspensions, including a $14,000 fine with a seven-month suspension, and a $27,000 financial penalty with a 10-month suspension. The outcome depends on the facts of each case, so treat these as examples of how seriously CEA views breaches, not as fixed amounts.
