Conveyancing transactions involving overseas clients carry a higher inherent risk of money laundering and come with a higher bar for due diligence.
Here is what enhanced checks involve, why international cases are more complex, and how to manage them effectively, en cinco minutos (we’re helping you with your international language there!)
Why are overseas conveyancing clients considered higher risk?
The UK property market has long attracted international buyers, and with them, an elevated risk of money laundering. Property is a well-established route for converting criminal proceeds into legitimate assets, and overseas clients introduce additional challenges that make due diligence harder to apply and easier to get wrong.
The SRA’s supervisory findings and the UK’s National Risk Assessment both identify international transactions as an area of increased concern. Residential conveyancing remains one of the highest-risk practice areas, and transactions involving overseas clients, particularly those linked to high-risk jurisdictions, overseas-sourced funds, or complex ownership structures, carry a heightened level of exposure.
The starting point for firms is recognising that a standard domestic customer due diligence approach may not be sufficient, and that enhanced due diligence will often be required.
When is enhanced due diligence required for international clients?
Enhanced due diligence is required under the Money Laundering Regulations whenever a higher risk of money laundering is identified. In the context of overseas clients, several factors commonly trigger this threshold.
A client who is not physically present presents a higher risk, as remote verification requires additional safeguards. Clients connected to high-risk third countries require increased scrutiny due to weaknesses in those jurisdictions’ AML frameworks.
Foreign politically exposed persons are treated as higher risk by default and require enhanced due diligence, including source of wealth checks and senior management approval. Where funds originate overseas, particularly where they pass through multiple jurisdictions or accounts, the complexity of verification increases and further scrutiny is required.
Any one of these factors may be sufficient to trigger enhanced due diligence. In practice, international transactions often involve more than one.
What does enhanced due diligence involve in practice?
Enhanced due diligence is not a single additional check, but a higher standard applied across the entire due diligence process.
For identity verification, firms need to consider whether their systems can genuinely support international checks. Not all digital identity providers can verify overseas documents, read foreign biometric chips, or access international data sources. Relying on systems designed for domestic use may create gaps in verification.
For source of funds, the evidential threshold is higher. Foreign bank statements may be more difficult to interpret or verify, and the regulatory environment of the originating country becomes relevant. Funds that move across multiple jurisdictions or accounts require careful tracing, and where the origin cannot be clearly linked to a legitimate source, this should be treated as a significant red flag.
For PEP and sanctions screening, checks must extend beyond UK databases. PEP status and sanctions exposure can vary by jurisdiction, and relying solely on domestic screening risks missing relevant information.
For ongoing monitoring, the same principle of proportionality applies, but risk profiles may change more quickly in response to geopolitical or regulatory developments. This means that reassessment may need to happen more frequently.
What challenges do firms face with international AML checks?
Enhanced due diligence for overseas clients presents practical challenges that go beyond standard domestic processes.
Staff may not be familiar with risk indicators associated with specific jurisdictions, making it harder to identify when something is unusual. Document verification is more complex, as overseas documents may not support NFC chip reading, may be issued in different formats, or may require translation.
Establishing ultimate beneficial ownership can also be more difficult. Corporate structures involving offshore entities and multiple layers of ownership can obscure who ultimately controls a transaction. Language barriers can slow the process and create gaps in understanding that introduce additional risk.
Firms should assess whether their current processes, systems, and expertise are sufficient for the type of international work they are undertaking
What does good AML practice look like for overseas clients?
Firms that handle international clients effectively tend to adopt a structured and proactive approach. This includes clearly distinguishing between domestic and international matters at the outset, ensuring staff are trained on jurisdiction-specific risk indicators, and using verification and screening tools with genuine international capability.
They are also prepared to ask more detailed questions, request additional documentation, and escalate concerns to the MLRO at an earlier stage where the risk profile is unclear. A cautious and enquiring approach is often the most effective safeguard.
OneSearch AML supports international due diligence through access to global PEP and sanctions datasets, adverse media screening, and international identity verification tools designed for cross-border transactions.
Working with overseas clients requires a shift from standard due diligence to a more investigative and risk-sensitive approach. The presence of international elements, whether in the client, the funds, or the ownership structure, increases complexity and reduces the reliability of assumptions that might hold in domestic cases. Enhanced due diligence is therefore not just a regulatory requirement, but a practical necessity.
Firms that approach these transactions with the right tools, clear processes, and a willingness to probe further are better placed to manage risk effectively and demonstrate compliance if challenged.
