What is customer due diligence (CDD) for a property agent?

CDD is the process of verifying a client's identity (and, where relevant, the beneficial owner behind them) before acting, as part of an agent's anti-money-laundering obligations.

When does an agent file a Suspicious Transaction Report (STR)?

When there are reasonable grounds to suspect that funds or a transaction are linked to criminal conduct, money laundering, proliferation financing or terrorism financing — even if the deal does not ultimately proceed. The salesperson who forms the suspicion is primarily responsible for filing, through the police's SONAR portal; if they report it to their agency but do not file, the agency must file instead. Never tip off the client.

Must I do due diligence on the other party if they have no agent?

Yes. Under the revised PMLPFTF Regulations, estate agents and salespersons must conduct Unrepresented Counterparty Due Diligence (UCPDD) on the other side of a sale or lease where that party is not represented by an agent — the same identity, beneficial-owner, PEP, sanctions-screening and risk-assessment checks you do for a client. Carry them out once it is clear the deal is likely to proceed, but before the parties enter into any agreement. Ongoing monitoring is the one duty that does not extend to an unrepresented counterparty.

Do the AML checks apply to HDB rental transactions?

HDB residential rentals — whole flat or room — have been exempt from CDD and UCPDD since 1 July 2025, because of their lower risk profile. The exemption does not cover anything else: all sales and purchases, and all non-HDB rentals, still require both. And it never removes the duty to file a Suspicious Transaction Report if something suspicious surfaces during the work.

Paper 2 · AML / CFT

AML/CFT for Property Agents: CDD, Source of Funds & STR

Property is a classic money-laundering vehicle, so estate agents are gatekeepers with legal duties — under the CDSA (Corruption, Drug Trafficking and Other Serious Crimes Act), the Terrorism (Suppression of Financing) Act (TSOFA), and CEA's Estate Agents (Prevention of Money Laundering, Proliferation Financing and Terrorism Financing) Regulations 2021 — the *PMLPFTF Regulations*. The exam expects the *mechanics*, not just awareness.

The AML reflex: red flag → CDD/EDD → if still suspicious, STR to the STRO (never tip off).

The core steps

Customer Due Diligence (CDD) — identify and verify the customer's identity before acting.
Identify the beneficial owner — the real natural person behind a company, trust or nominee.
Understand the purpose of the transaction and the source of funds.
Ongoing monitoring of the business relationship.
Keep records for at least 5 years.

CDD vs Enhanced Due Diligence (EDD)

	Standard CDD	Enhanced DD (EDD)
When	Normal-risk clients	Higher-risk: PEPs, foreign/complex, large cash
Depth	Verify ID + beneficial owner	Extra checks on source of wealth/funds, senior approval

When CDD applies & what 'verify' means

Trigger: when establishing the business relationship / before acting for the client (and again if something looks suspicious).
Individuals: verify identity with reliable documents (NRIC / passport).
Companies / trusts: obtain registration documents and identify the directors / beneficial owners behind them.
Screen against sanctions and PEP lists, and understand the purpose and expected nature of the transaction.

Red flags to watch

Reluctance to provide ID or reveal the beneficial owner.
Large cash payments or funds from unclear/third-party sources.
Buyer indifferent to price, or rushing an unusual deal.
Politically Exposed Persons (PEPs) or sanctioned/high-risk jurisdictions.

Suspicious Transaction Reports

If you have reasonable grounds to suspect money laundering or terrorism financing, you must file a Suspicious Transaction Report (STR) to the Suspicious Transaction Reporting Office (STRO) — even if the deal does not proceed. Failing to report is itself an offence; and you must not “tip off” the client that an STR has been filed.

Records, compliance programme & penalties

Keep CDD records and transaction documents for at least 5 years.
Agencies must run an AML/CFT programme — internal policies, staff training, and independent audit/compliance checks.
Non-compliance (failing CDD, failing to file an STR, or tipping off) is an offence carrying fines and/or imprisonment.

The 2025 overhaul — full compliance from 1 Jan 2026

CEA rewrote this regime in 2025, amending both the Estate Agents Act 2010 and the Regulations. Note the extra P in the new name: proliferation financing (PF) — the funding of weapons of mass destruction — now sits alongside ML and TF, so every risk assessment and every sanctions screening covers ML / PF / TF. CEA gave the industry until 31 Dec 2025 to implement, and requires full compliance for transactions from 1 January 2026. This is live law, and examinable.

Unrepresented Counterparty Due Diligence (UCPDD) — the headline new duty. You must now run due diligence on the other side of the deal where that party has no agent of their own: identity, beneficial owner, PEP status, sanctions screening, ML/PF/TF risk assessment, and enhanced checks where triggered. Timing: once it is clear the deal is likely to proceed, but before the parties enter into any agreement — i.e. before the OTP is issued or the tenancy agreement is signed.
HDB residential rental is exempt. From 1 Jul 2025, HDB whole-flat and room rentals need no CDD and no UCPDD (lower risk profile). Everything else — all sales and purchases, and all non-HDB rentals — still needs both. The STR duty is never exempt: spot something suspicious in an HDB rental and you must still report it.
Penalties moved from 'per case' to 'per breach'. A CEA Letter of Censure can carry up to $5,000 per breach; a Disciplinary Committee can impose up to $200,000 per breach on an estate agent and $100,000 per breach on a salesperson. Ten sloppy files are ten penalties, not one.
Fit and proper — a conviction for a money-laundering, proliferation-financing or terrorism-financing offence, in Singapore or elsewhere, disqualifies a person from holding an EA licence or an RES registration.
Who files the STR — the salesperson who has reason to suspect is primarily responsible for filing (via the police's SONAR portal). If the salesperson reports the suspicion to their agency but does not file, the agency must file instead.
Agency-side controls — a group-wide PMLPFTF programme extending to branches and majority-owned subsidiaries (in Singapore and overseas), a Compliance Officer at management level (CEO/KEO, director, partner or other authorised officer), and an independent audit — *independent* meaning the person reviewing a file cannot be the one who handled that transaction.

Duty	Your client	Unrepresented counterparty
Establish the agency relationship / sign an agreement	Yes	No — they are not your client
Obtain and verify identity; identify the beneficial owner	Yes	Yes
Determine PEP status; screen against UN / TSOFA sanctions lists	Yes	Yes
Enhanced due diligence where triggered	Yes	Yes
Keep records (5 years)	Yes	Yes
Ongoing monitoring of the relationship	Yes	No
File an STR on suspicion	Yes	Yes

Client vs unrepresented counterparty under the revised PMLPFTF Regulations. The checks themselves are identical — only two duties differ.

Common mistakes

Skipping CDD for a 'trusted' repeat client.
Tipping off the client that an STR was (or will be) filed.
Checking only your own client — since the 2025 amendments you must also run UCPDD on an unrepresented buyer, seller, landlord or tenant on the other side.
Leaving the checks until completion — CDD/UCPDD must be done before the OTP is issued or the tenancy agreement is signed.
Not keeping records for the full 5 years.

The trap

Skipping CDD for a “trusted” repeat client, assuming AML only concerns the buyer, or thinking you can warn the client about an STR — that tipping-off is an offence. Duties apply throughout the engagement; a long relationship is not an exemption.

Higher-risk clients & sanctions

Risk-based approach: apply more scrutiny to higher-risk clients and transactions, and proportionately less to clearly low-risk ones.
Politically Exposed Persons (PEPs): a *foreign* PEP automatically triggers Enhanced Due Diligence; a *domestic* PEP does so where a risk assessment finds higher risk.
Sanctions: screen customers against the UN/MAS designated lists; on a match, do not proceed, freeze the relevant funds and report as required.

The three stages & red flags

Money laundering runs in three stages: placement (cash enters the system), layering (disguising origin through transactions), integration (funds return looking legitimate).
'Structuring' (smurfing) — breaking a large sum into smaller amounts to dodge reporting thresholds — is a classic red flag, along with large unexplained cash, routing through unrelated third parties, and evasiveness about the source of funds.
ML is criminalised under the CDSA; terrorism financing (which may use clean money) under the TSOFA. An agency needs an internal AML programme, a compliance officer/MLRO, staff training and 5-year record retention.

Exam takeaway

CDD (plus UCPDD on an unrepresented other side) → find the beneficial owner → check source of funds → escalate to EDD if high-risk → file an STR (no tipping off) → keep records 5 years. That chain answers most AML questions. Since 2025 the risk you screen for is ML / PF / TF, and the only carve-out from CDD/UCPDD is HDB residential rental.

Apply it · the IRAC method

A buyer insists on paying a large part of the price in cash and turns evasive when asked where the money came from.

IIssue: What are the salesperson's anti-money-laundering (AML/CFT) obligations in this situation?
RRule: Under the CDSA and CEA's AML/CFT requirements, a salesperson must carry out Customer Due Diligence (CDD) — identify the client and any beneficial owner and understand the source of funds. If suspicion persists they must file a Suspicious Transaction Report (STR) with the STRO, and must never 'tip off' the client.
AApplication: Large unexplained cash plus evasiveness are textbook red flags, so enhanced CDD is required. If the source of funds still can't be satisfactorily established, the salesperson files an STR — quietly, without alerting the client.
CConclusion: Proceeding without CDD, or warning the client, would breach the rules. Correct path: CDD → if still suspicious → STR to the STRO, with no tipping off.

Worked case study · Section B style

A buyer wants to pay largely in cash, is evasive about his source of funds, and asks to register the unit in an unrelated third party's name. • Heavy cash • Possible nominee ownership

(i) These are AML red flags that call for enhanced customer due diligence
(ii) The agent should verify identity and the source of funds
(iii) If suspicion remains, a Suspicious Transaction Report (STR) should be filed, without tipping off
(iv) Apparent wealth means the checks can be waived

A.(i), (ii) and (iii) only
B.(i) and (iv) only
C.(iii) only
D.All of the above

Show answer & explanation

Answer: A. (i)–(iii) are correct: red flags → EDD, verify source of funds, file an STR without tipping off. (iv) is the trap — apparent wealth never waives the checks.
