Enhanced Due Diligence Checklist

Certivus AML team8 minUpdated 2026-06-27

In brief: Enhanced due diligence is the extra evidence, approval, and monitoring a firm applies when the normal CDD file is not enough for the risk.

Key points

  • EDD should be triggered by risk, not applied randomly.
  • Common EDD steps include extra verification, source-of-funds checks, source-of-wealth context, and senior approval.
  • The file should explain how the extra checks reduced or clarified the risk.

Enhanced due diligence checklist

Use enhanced due diligence when client, matter, geography, product, delivery channel, PEP, sanctions, adverse media, or transaction facts create higher risk.

EDD stepEvidence to keep
Trigger noteWhy standard CDD was not enough.
Extra verificationAdditional ID, company, ownership, or control evidence.
Source of fundsWhere the money for the matter or transaction came from.
Source of wealthHow the client built the wider wealth behind the funds.
Screening reviewPEP, sanctions, adverse media, and false-positive notes.
Senior approvalWho approved onboarding or continuation.
Monitoring planWhat changes should trigger another review.

What EDD is not

EDD is not a longer form for every client. It is a targeted response to higher risk. If the extra evidence does not make the position understandable, escalation or refusal may be the right answer.
