Enhanced due diligence

Enhanced due diligence (EDD): scope, evidence and automation

Last updated 2 October 2026 · General information, not legal advice.

Enhanced due diligence is the deeper level of inquiry applied when a customer, counterparty or transaction carries higher risk. This page explains what it involves, what a defensible scope report contains, and where automation helps.

What is enhanced due diligence?

Standard due diligence confirms who a customer or counterparty is and whether there is an obvious reason not to proceed. Enhanced due diligence (EDD) goes further where the risk is higher. It looks more closely at ownership and control, the nature of the business, the origin of funds or wealth and any adverse information. It usually brings more senior sign-off and closer ongoing monitoring.

When is it used?

Requirements depend on the jurisdiction and the sector. Under EU anti-money laundering rules, firms must apply enhanced measures in higher-risk situations, for example where a business relationship involves a politically exposed person or a high-risk third country, and in other cases the firm assesses as higher risk. Beyond regulated onboarding, organizations also use EDD for acquisitions and investments, for critical suppliers and for complex cross-border structures.

Your compliance function and legal advisers decide what applies to your organization.

What does a defensible scope report contain?

A scope report defines the investigation before the detailed work starts. A defensible one lets a reviewer see what was found, where it came from and what remains open.

The entity identified precisely: legal name, registration number, registry and status.
Ownership and control as filed, with the date of each source.
Directors, officers and other roles shown in the registry record.
Key filings and data points, such as accounts, changes of capital and the registered address.
Gaps and conflicts between sources, flagged for follow-up.
A source link for every statement, so any finding can be checked against the original document.
A record of who reviewed the report and what they concluded.

Where the time goes

For many teams the first hours of each case go into collecting filings from registries, organizing them, picking out the relevant data points and compiling the scope report. That preparation limits how many cases each analyst can complete, before any judgment about risk has been made.
