What is Enhanced Due Diligence (EDD)?
The short answer
Enhanced due diligence applies deeper investigation to relationships whose risks or applicable requirements call for additional evidence.
Enhanced Due Diligence (EDD): why it matters
An onboarding or review decision can contain several different questions. Keeping this concept distinct helps the team assign the right evidence and decision owner, rather than rely on a single completed status.
How to assess it in practice
Define the unresolved risk question and select extra evidence that addresses it instead of merely requesting more documents. Start by defining the question the team needs to answer. Identify the relevant record or evidence, check its scope and date, and retain the reasoning behind the result. If evidence conflicts, keep that conflict visible for review.
Worked example
Illustrative workflow: a team reviewing a business adds a separate check for enhanced due diligence (edd). The reviewer’s task is to define the unresolved risk question and select extra evidence that addresses it instead of merely requesting more documents. The outcome is recorded together with the supporting evidence; an unresolved question stays open rather than being converted into a positive result.
An ownership chain crosses an opaque intermediary. The reviewer seeks evidence about control at that layer instead of repeating the initial company search.
Distinctions that matter
Enhanced Due Diligence (EDD) belongs to the due diligence methods topic family. Read Customer Due Diligence (CDD) alongside it to understand the adjacent question. Each page has its own intended scope; shared context does not make the concepts equivalent.
Evidence and review output
Review these
- Customer and relationship context
- Risk factors and evidence gaps
- Review depth and approval basis
The review should produce
A documented assessment explaining the review approach, evidence considered and conditions attached to any acceptance decision.
Across this family
The depth of review should follow the specific risk question and applicable framework. Document why additional or reduced checks are appropriate, which evidence can answer the question and what uncertainty remains. Escalation should resolve a defined issue rather than merely add another approval signature.
A note from practice
EDD should investigate the factors that make a case higher risk. Specify the concern, select additional evidence and assess whether it resolves the concern; a larger document bundle alone does not demonstrate deeper review.
Limits and common mistakes
The practical boundary is important: Define the unresolved risk question and select extra evidence that addresses it instead of merely requesting more documents. Do not substitute a related label for this check or assume that missing information is a negative finding. Source-specific and jurisdiction-specific rules require their own review.

For a corporate customer, the file often combines company identity, ownership, representatives and an explanation of the intended activity. The aim is an evidence-supported decision that can be reviewed later, rather than a collection of unchecked documents.
