Dual Representation & Conflict of Interest (RES)

Practise this section (175 questions) → · 3.2 Professional practice, ethics and conduct, in sets of about 30

Must-know for the exam

  • Regulation 5(1) of the Estate Agents (Estate Agency Work) Regulations 2010 bars having both vendor and purchaser, or both landlord and tenant, as clients for the same property.
  • Under regulation 5(2) the ban applies regardless of the consent or agreement of the client or any of the parties, so disclosure can never cure dual representation.
  • Under regulation 5(3) dual representation is an offence carrying a fine of up to $25,000, imprisonment of up to 12 months, or both, on top of CEA disciplinary action.

Conflict-of-interest rules are core to the CEA framework and a reliable source of exam questions — mostly because candidates confuse what's prohibited (dual representation) with what's allowed (co-broking), and get the disclosure point wrong.

The rule is regulation 5 — and it is a criminal offence

Candidates lose marks here by filing dual representation under "the Code of Ethics". It is not in the Code at all. It sits in regulation 5 of the Estate Agents (Estate Agency Work) Regulations 2010, headed "No dual representation", drafted in three tight limbs worth knowing precisely:

  • Reg 5(1) — the prohibition. No salesperson or estate agent who is a natural person shall, in respect of the same property, have as clients both vendor and purchaser or both landlord and tenant. Note the two words the exam leans on: the test is the same property, and it turns on who your clients are.
  • Reg 5(2) — consent is irrelevant. The prohibition applies regardless of the consent or agreement of the client or of any or all the parties to the relevant transaction. That is the statutory answer to "but I disclosed it and both sides agreed" — the legislation forecloses it in terms, which is why disclosure can never cure it.
  • Reg 5(3) — it is an offence. On conviction: a fine of up to $25,000, imprisonment of up to 12 months, or both — the same ceiling as the regulation 6 moneylender ban, and heavier than the regulation 7 transaction-money offence ($10,000 / 6 months). CEA has prosecuted salespersons for it in court.

Why the ban is absolute is easy to see: the seller wants the highest price and the buyer the lowest, so genuine loyalty to both is impossible. Taking a fee from both sides is the clearest evidence you had both as clients — but the offence is complete once both are your clients, whoever ends up paying you.

Prohibited vs allowed — don't confuse these

The seller has a salesperson. Who may act for the buyer?

Decision flow for a property where the seller already has a salesperson. Step 1: if the buyer has no salesperson, the seller's salesperson acts for the seller only; with the seller's agreement she may give basic help such as explaining policies and procedures, but may not negotiate the price for the buyer or collect a commission from him. Step 2: if the seller's own salesperson would act for the buyer too, that is dual representation, an offence under regulation 5 of the Estate Agents (Estate Agency Work) Regulations 2010, with a fine of up to 25,000 dollars, up to 12 months' imprisonment or both, and consent does not cure it. Step 3: is the buyer's salesperson in the same team as the seller's salesperson, meaning he shares her commission or takes an overrider, is her spouse, parent, sibling or child or an in-law of those kinds, markets the property with her, or sits in the same division, group or team? Step 4: if so, he may act for the buyer only if the buyer engaged him for a general search before he marketed this property to the buyer; he must still declare the tie in writing and get written consent, and may never act for the seller too. Otherwise he is barred. Step 5: a salesperson outside the team but from the same estate agency may co-broke after disclosing that in writing to the client. A salesperson from another agency is an ordinary co-broke. In every case each salesperson takes commission only from his own client.

  1. Does the buyer have a salesperson of his own?

    • No: unrepresented

      Watch out: The seller's salesperson still acts for the seller only. With the seller's agreement: basic help, such as explaining procedures. No price negotiation for the buyer, no fee from him (PSM 1.3.6).

    • Yes, or he wants one

      Go to step 2 ↓
  2. Who would act for the buyer?

    • The seller's own salesperson

      Not allowed: Dual representation: an offence under reg 5. Fine up to $25,000, up to 12 months, or both. The parties' consent does not cure it (reg 5(2)).

    • A different salesperson

      Go to step 3 ↓
  3. Is he in the seller's salesperson's team?

    Same team if he shares her commission or takes an overrider, is her spouse, parent, sibling, child or in-law of those kinds, markets the listing with her, or sits in her division or group (PSM 1.8.5).

  4. Did the buyer engage him for a general search before he marketed this property to the buyer?

    • Yes

      Watch out: He may act for the buyer. Declare the tie in writing and get the buyer's written consent (PSM 1.3.5). Never for the seller as well.

    • No

      Not allowed: Barred from the buyer's side (PSM 1.8.5). Disclosure and consent do not lift it.

  5. Is he from the same estate agency as the seller's salesperson?

    • Yes

      Watch out: A lawful co-broke, but disclose in writing to the client that both are from the same agency (PSM 1.3.4).

    • No

      Allowed: An ordinary co-broke. Each salesperson takes commission only from his own client (PSM 1.3.6).

The seller's own salesperson: never, a reg 5 offence whatever the consent. A team member: only if the buyer engaged him first. Anyone else: a co-broke, declared in writing if same agency.

SituationAllowed?Why
One agent acts for both buyer & seller in the same dealNoDual representation — prohibited
Co-broking: a buyer's agent + a separate seller's agent (different salespersons/agencies)YesEach represents one side; must be disclosed & properly co-broked
The other side's salesperson is from your own agency but not in your teamYes — but declare itNot dual representation, but a conflict: disclose in writing that both salespersons are with the same estate agent (PSM 1.3.4)
The buyer's salesperson is in the seller's salesperson's team: same division or group, shares her commission, markets the listing with her, or is her spouse, parent, sibling, child or in-lawNo — unless the buyer engaged him firstThe same-team bar in PSM para 1.8.5 — see the section below
Placing a colleague on the other side while you in substance serve both, or take a fee from bothNoSubstance over form — the arrangement does not cure the ban
Agent has a personal interest (e.g. buying it themselves / related party)Only with a written declaration and the client's express knowledge and consentPara 13(2)(a), (c) and (d): disclosure alone is not enough; without consent, decline or withdraw

So co-broking is not dual representation — it's the normal way two sides are each represented. The line is crossed when the same salesperson tries to serve both sides on one property. Two refinements the exam likes: CEA looks at substance, not labels, so a salesperson who in substance or effect acts for — or is paid by — both parties breaches the ban even if a colleague is nominally put on the other side; and where the other side's salesperson is from your own agency but outside your team, that is a genuine co-broke but a declarable conflict, to be disclosed in writing in the estate agency agreement (or immediately in writing if it surfaces later). A related salesperson is a different case: the same-team rule below usually bars him from the buyer's side altogether.

Why an intra-agency co-broke is lawful at all — the answer is in reg 5(1)'s own words. The prohibition binds a salesperson and an *estate agent who is a natural person*. A licensed estate agency that is a company or partnership is therefore not itself caught by reg 5(1), which is precisely why two different salespersons of the same agency may each act for one side, provided they are not in the same team* (next section). What that does not do is switch off the conflict rules: the connection must still be declared in writing* under paragraph 13 of the Code, below.

And if the other party is unrepresented, you still act for your client alone — but you must make sure that party understands you do not represent them and are not looking after their interests. Being helpful to them is fine; letting them believe you are their agent is not.

Say your answer out loud, then tap to check it.

  1. Where is the dual-representation ban found, and what is the maximum penalty?Show answer

    In regulation 5 of the Estate Agents (Estate Agency Work) Regulations 2010, not the Code. Under reg 5(3) it is an offence: a fine of up to $25,000, imprisonment up to 12 months, or both.

  2. If both buyer and seller agree in writing, may one salesperson act for both on the same property?Show answer

    No. Reg 5(2) applies the ban regardless of the consent or agreement of the client or of any or all the parties, so disclosure can never cure it.

  3. Why may two salespersons of the same agency act for opposite sides, and what must they do?Show answer

    Reg 5(1) binds salespersons and estate agents who are natural persons, not a company agency. They must not be in the same team, and must still declare in writing that both are with the same agency (PSM 1.3.4).

  4. Under PSM para 1.8.5, what four links put two salespersons in the same team?Show answer

    Money (overrider or commission share), family (spouse, parent, sibling, child or in-law), marketing the property together, and structure (same division, group or team). A team member may still act for a buyer who engaged him for a general search first.

  5. What must you disclose before taking a referral fee for a third-party service?Show answer

    Both the fact and the quantum, in advance and in writing (Code para 13(3)), with the client's express knowledge and prior written consent. Naming the fee but withholding the amount still breaches the Code.

Common questions

Can one agent represent both buyer and seller in Singapore?
No. Regulation 5(1) of the Estate Agents (Estate Agency Work) Regulations 2010 provides that no salesperson, or estate agent who is a natural person, shall in respect of the same property have as clients both vendor and purchaser or both landlord and tenant. It is not merely a Code of Ethics breach: regulation 5(3) makes it an offence carrying a fine of up to $25,000, imprisonment of up to 12 months, or both.
Is dual representation allowed if both sides agree?
No. Regulation 5(2) states expressly that the prohibition applies regardless of the consent or agreement of the client or of any or all the parties to the transaction. Disclosure and mutual consent therefore cannot cure it — which is the opposite of how ordinary conflicts of interest work under paragraph 13 of the Code of Ethics and Professional Client Care, where a fully-informed client's consent is what allows the salesperson to continue acting.
Can a salesperson co-broke with someone from the same estate agency?
Yes, if the two salespersons are not in the same team. Each represents one party, so it is co-broking, not dual representation, but it is a conflict of interest to disclose to the client in writing (PSM para 1.3.4). Under PSM para 1.8.5, a salesperson in the seller's salesperson's team — same division or group, sharing her commission, marketing the listing with her, or her spouse, parent, sibling, child or in-law — may not act for the buyer unless the buyer engaged him for a general search before he raised the property. CEA also looks at substance: putting a colleague on the other side while you still act for, or are paid by, both parties is not allowed.
