10 Money Laundering Red Flags in Property Transactions

Conveyancing is one of the highest-risk legal services for money laundering, according to the Solicitors Regulation Authority’s sectoral risk assessment. The Law Society also identifies property transactions as a significant money laundering risk, given the substantial sums involved and the opportunities they can create to move or disguise illicit funds. 

Whether you are a solicitor or conveyancer, you have a role to play in identifying suspicious activity during property transactions. Warning signs are not always obvious, and one red flag alone does not necessarily mean money laundering is taking place. The key is recognising unusual circumstances and responding appropriately.

This article covers ten key money laundering red flags in property transactions, what they can look like in practice, and what to do when you spot them. It is not an exhaustive list: risks vary between clients and transactions, so a risk-based approach and professional judgement remain essential. 

Key Takeaways: Money Laundering Red Flags in Property

• One red flag does not prove money laundering. Unusual, inconsistent or unexplained circumstances call for closer scrutiny.
• Common property red flags include cash payments, unverifiable client information, nominees and intermediaries, complex ownership structures, high-risk jurisdictions, PEPs, mispricing, rapid resales, pressure to skip checks and complex financing.
• The core response is to establish and evidence the source of funds, verify beneficial ownership, apply EDD where the risk is higher, and document your reasoning.
• Do not proceed where the required due diligence cannot be completed.
• If you know or suspect money laundering, report it internally to your MLRO, who decides whether to submit a SAR to the UKFIU. Do not tip off the client.

What Is Money Laundering?

Money laundering in real estate is the process of disguising the origins of illegally obtained money by using it to buy, sell or invest in property, making the funds appear legitimate.

Money laundering typically happens in three stages: placement, where illicit funds first enter the financial system; layering, where the money is moved through a series of transactions to obscure its original source; and integration, where the laundered funds are reintroduced into the legitimate economy. Property can feature across all three stages, particularly where transactions involve significant sums or complex financial arrangements.

Real estate can be particularly attractive because transactions often involve high values, complex ownership structures, and opportunities to move funds through multiple parties or entities. Property can also appreciate over time, potentially allowing illicit funds to be converted into assets that appear to have a legitimate source of value.

10 Key Money Laundering Red Flags in Property Transactions

Spotting potential money laundering means recognising circumstances that are unusual, inconsistent or difficult to explain, rather than looking for one definitive sign. 

The following red flags highlight situations that should prompt further scrutiny, appropriate checks and, where necessary, escalation.

1. Large or Unusual Cash Payments

Large or unusual cash payments can be a warning sign because cash makes it more difficult to establish where funds have actually come from. This is particularly significant where cash is unusual for the size or nature of the property transaction, or does not fit what you know about the client and their financial circumstances.

What To Do: Establish and document the source of funds, requesting appropriate evidence to support the client’s explanation. Do not proceed with the transaction until the source of the funds has been satisfactorily established and any concerns have been addressed. 

Where suspicion remains, consider whether a Suspicious Activity Report (SAR) should be made and whether a Defence Against Money Laundering (DAML) is required before proceeding.

2. Incomplete, Inconsistent, or Unverifiable Client Information

Vague, conflicting, confusing, or unverifiable client information can indicate an attempt to obscure someone’s identity, ownership, or financial circumstances. Be alert to discrepancies in names, addresses, identification documents, or financial records, particularly where the client is unable or unwilling to provide a credible explanation.

What To Do: Re-check the information against reliable (and independent) sources and investigate any discrepancies. Where the circumstances indicate a higher level of risk, apply enhanced due diligence and document the reasons for your decision-making. 

Do not proceed until you are satisfied that you know who the client and, where relevant, the beneficial owner are.

3. Use of Third Parties, Intermediaries, or Nominees

Third parties, intermediaries, or nominees can create distance between you and the person who ultimately owns or controls the property or funds. This can make it harder to establish who is really behind a transaction and, in some circumstances, may be used to obscure beneficial ownership. 

An unusually large number of intermediaries, overseas intermediaries, or a lack of clear rationale for their involvement can increase the risk.

Gifted deposits are not inherently suspicious, but they should still be properly understood and evidenced. Where a family member or another third party is contributing to a purchase, establish who is providing the funds, why they are being provided, and the source of those funds. Unexpected third-party payments or funds from someone not previously identified should prompt further scrutiny.

What To Do: Establish the identity of the person or entity you are actually dealing with, confirm that any intermediary is genuinely authorised to act and identify the relevant beneficial owner. 

Where appropriate, seek direct contact with the underlying buyer or seller and ask why an intermediary or nominee is being used. Investigate and document any concerns before proceeding.

4. Complex Ownership Structures or Shell Companies

Complex or unusual ownership structures can make it difficult to establish who ultimately owns or controls a property. Multiple layers of companies, trusts, or overseas entities can obscure beneficial ownership and, in some cases, make it harder to trace the flow of funds.

 HMRC identifies complex corporate structures, particularly those extending overseas or appearing to be shell companies, as an increased money laundering risk.

What To Do: Identify and verify the Ultimate Beneficial Owner (UBO) and, where applicable, the company’s Persons with Significant Control (PSCs) and relevant overseas beneficial ownership information. Check this against reliable sources, such as Companies House and the Register of Overseas Entities, and investigate any discrepancies or unexplained layers of ownership. 

Where the relevant conditions are met, firms may also have a duty under regulation 30A to report material discrepancies between information they hold and information recorded on the relevant Companies House register.

If the ownership or control cannot be established with sufficient confidence, do not proceed until the necessary checks have been completed.

5. Clients or Funds Linked to High-Risk Jurisdictions

Clients, counterparties, or funds linked to jurisdictions with significant weaknesses in their anti-money laundering controls can present increased risk. A connection to a higher-risk jurisdiction does not, on its own, mean that money laundering is taking place, but it should prompt closer consideration of the client, transaction, and source of funds.

What To Do: Check the latest FATF position and relevant sanctions regimes. Financial sanctions are separate from AML requirements, so firms should also carry out appropriate sanctions screening and consider whether any reporting obligations to the Office of Financial Sanctions Implementation (OFSI) arise.  

Where a relationship or transaction falls within the requirements for a FATF Call for Action country, the Money Laundering Regulations require enhanced customer due diligence and enhanced ongoing monitoring.

6. Politically Exposed Persons (PEPs) & Their Associates

Politically Exposed Persons (PEPs) are individuals entrusted with prominent public functions, such as senior political or government roles. Because of their positions and influence, PEPs can present an increased risk of money laundering linked to bribery or corruption. 

Relatives and Close Associates (RCAs) can also require closer scrutiny where their relationship with a PEP creates additional risk. A close associate may, for example, share beneficial ownership of a company or have a close business relationship with the PEP.

Domestic PEPs should be treated differently from non-domestic PEPs. Under the Money Laundering Regulations, the starting point is that a person entrusted with prominent public functions by the UK presents a lower level of risk than a non-domestic PEP. Where no other enhanced risk factors are present, the extent of enhanced due diligence should also be lower.

What To Do: Apply enhanced due diligence where required, including establishing the source of wealth and source of funds and obtaining the necessary senior management approval. 

Continue to monitor the relationship throughout, rather than treating PEP screening as a one-off onboarding check. A person's risk profile can change over time, so ongoing monitoring should reflect the circumstances and level of risk involved.

7. Property Priced Significantly Above or Below Market Value

A property being bought or sold for significantly more or less than its genuine market value can be a red flag, particularly where there is no credible commercial reason for the difference. 

For example, an undervalued sale can have a legitimate explanation, but it may warrant additional scrutiny where the circumstances suggest vendor fraud, a preferential transfer, or an attempt to move an asset below its genuine value.

What To Do: Compare the agreed or proposed price with trusted market data or a professional valuation. Where there is a significant discrepancy, establish why the property is being bought or sold at that price and obtain supporting evidence for the explanation. Document your assessment and investigate further where the rationale is not credible.

8. Fast Buying & Selling of Property

Quick purchases and resales of property can be a red flag where there is no clear commercial or personal reason for the speed of the transactions. Property can be used as part of a laundering process to move or legitimise illicit funds, particularly where ownership, funding or the parties involved change unexpectedly. 

HMRC identifies transactions that progress at an unusual speed (or where parties are introduced late in the process) as higher-risk indicators.

What To Do: Establish why the property is being bought and resold so quickly and whether the explanation makes sense in the wider context of the transaction. Verify the identity, ownership and source of funds of all relevant parties, and investigate any unexpected changes or unexplained links.

9. Pressure To Rush the Transaction or Skip Standard Checks

Unusual pressure to complete quickly, avoid property searches, or bypass standard due diligence should raise concerns. 

The Law Society’s property market risk guidance highlights a case where clients demanded a rapid sale with no searches, later found to be using forged passports in a property hijacking fraud. In another case, a solicitor accepted £20,000 into the client account before AML checks had been completed; the solicitor was subsequently referred to the Solicitors Disciplinary Tribunal.

What To Do: Do not allow time pressure to override your AML obligations. Carry out the required customer due diligence and source-of-funds checks before proceeding, and do not accept or transfer funds where you have not obtained sufficient information to establish their legitimacy. 

The SRA advises obtaining source-of-funds information as early as possible and states that, where required due diligence cannot be completed, the transaction should not proceed.

10. Complex Financial Arrangements

Unusually complicated financing can make it harder to understand where money is coming from and who is ultimately funding a transaction. Multiple loans, unexpected changes in funding, overseas or unfamiliar lenders, and bridging finance can all increase the risk, particularly where the arrangements are difficult to explain or document. 

HMRC specifically identifies complex loans, unknown or overseas mortgages, and bridging finance as higher-risk indicators.

What To Do: Scrutinise the financing arrangements and establish who is providing the funds, where those funds originated, and why that particular structure is being used. Verify loans and lenders independently, obtain supporting documentation, and investigate anything that is unexplained, inconsistent, or does not make commercial sense.

The same scrutiny should apply where funds have originated from cryptoasset activity.

Be particularly alert to funds arriving from a bank account that is not in the client's name or was not previously disclosed. This can indicate that an undisclosed third party is funding the transaction or obscure who is actually providing the money.

FAQs

• What is the difference between money laundering and vendor fraud?

  Money laundering involves disguising the origin of criminal funds or making criminal property appear legitimate. In a property transaction, this could involve using illicit funds to buy or invest in property, or moving those funds through a conveyancing transaction.

  Vendor fraud concerns who has the authority to sell the property, whereas money laundering concerns the origin or subsequent handling of criminal property or funds.

  In practice, the two risks can overlap. The two can overlap because the proceeds from a fraudulent property sale may themselves become criminal property and be moved through the financial or conveyancing system.

• What should I do if I spot a red flag during a transaction?

  Do not ignore it or allow commercial pressure to override your AML procedures. Stop and investigate the concern, carry out any additional customer due diligence or source-of-funds checks required by the circumstances, and document your assessment.

  If your enquiries lead you to know or suspect that money laundering or terrorist financing may be taking place, follow your firm's internal reporting procedure and report the matter promptly to the nominated officer (or MLRO). They will assess whether a Suspicious Activity Report should be submitted to the UK Financial Intelligence Unit (UKFIU).

• What is a Suspicious Activity Report (SAR), and when should one be filed?

  A Suspicious Activity Report is a report of suspected money laundering or terrorist financing submitted to the UKFIU, part of the National Crime Agency (NCA).

  In a regulated firm, an employee who knows or suspects money laundering should normally make an internal disclosure to the firm's nominated officer/MLRO, following the firm's procedures. The nominated officer then decides whether a SAR should be submitted to the UKFIU.

  Do not discuss a suspicion or SAR with the client or with colleagues who do not need to know. Disclosing information in a way that is likely to prejudice a money laundering investigation can amount to tipping off, which is an offence under section 333A of the Proceeds of Crime Act 2002. At the same time, firms should retain appropriate confidential records of internal disclosures and their decisions, as required by their AML procedures.

• What's the difference between standard and enhanced due diligence?

  Standard customer due diligence involves establishing who the customer is, verifying their identity, identifying any relevant beneficial owner, and understanding the purpose and intended nature of the relationship or transaction. The checks should be appropriate to the level of risk involved.

  Enhanced due diligence (EDD) involves additional measures where the risk of financial crime is greater. Depending on the circumstances, this can include obtaining more information about the customer, source of wealth and source of funds, carrying out additional verification, and obtaining senior management approval. EDD is required in specified higher-risk circumstances and should be proportionate to the risk identified.
