Source of Funds - a simple explainer for your clients

This guide explains why law firms are legally required to ask about the source of funds when handling a matter. It reassures clients that firms only collect what’s necessary, keep information secure, and comply with UK anti-money laundering (AML) laws designed to protect both the client and the firm. It also provides practical examples of the documents clients may be asked to supply, along with tips to make the process smoother. You can download it, add your firm’s logo, and use it as a helpful tool when reaching out to clients to identify their source of funds.

What’s inside:

  • What’s required and why: Explains AML obligations, why checks are needed, and what documents might be requested (e.g. payslips, bank statements, sale agreements).
  • How the checks work: Outlines how far back firms may look, what triggers requests for additional information, and when enhanced checks are needed (e.g. complex funds, overseas sources, PEPs).
  • What clients can do: Practical steps such as telling the firm early how the matter will be funded, providing clear document trails, and sharing information securely to avoid delays.
