Client Identity and Due Diligence Request Letter

About this document

What it’s for

A ready-to-send letter, document checklist by client type, client information and declaration form, and certification wording, so that you can collect what the Money Laundering Regulations 2017 (as amended) require in one go, and explain it in a way clients accept.

When to use it

  • Every new client, before you start work
  • When you refresh due diligence on an existing client under your review cycle
  • When a client’s ownership, directors or circumstances change

What’s inside

The document is laid out in the sections below. Each one comes with a plain-English guidance note explaining what it does and what to change.

  • What we need from you
  • How to send your documents securely

  • List 2 – proof of address (one of, dated within the last three months unless stated)
