Due diligence is the step where you test whether a counterparty is acceptable before you rely on it. The useful evidence usually sits across ownership, directors, filings, sanctions, and reputation signals rather than in one source.
Start with the basics
Confirm the entity first, then check the evidence that should support it. If the name, number, or status does not line up, stop treating the record as clean.
Review the evidence
- the entity should be verified before you rely on it
- screening should include ownership, directors, and reputation
- uncertainty should trigger a deeper evidence review
Follow-up questions
Ask what changed, what is missing, and whether the current record still matches the commercial relationship you are reviewing.
When to escalate
If the result is incomplete or contradictory, check the surrounding records before you proceed. A checklist only helps if the underlying data is current enough to trust.
