Investigative Due Diligence
An in-depth form of Due Diligence in which standard registry-based verification is supplemented with investigative methods: analysis of connections, identification of undisclosed conflicts, verification of the origin of key statements and work across multiple jurisdictions.
Practical significance
Applied when the cost of error is high and a formal check produces too smooth a picture. It is the investigative approach that finds what is not found in registers: hidden conflicts of interest, related parties, signs of nominee ownership.
Where it is used
- major transactions and partnerships
- disputes and litigation preparation
- checks with an international element
- situations with suspected hidden interests
What the term does not mean
This is not surveillance or access to restricted data: investigative methods remain within legal limits - what changes is the depth of analysis, not the legality of the sources.
How it differs from «Due Diligence»
Standard Due Diligence confirms what is stated; the investigative form actively looks for what is not stated: hidden connections, conflicts and inconsistencies. More about this term
Illustrative example
A formal check of the counterparty is clean, but investigative analysis finds that three of its "independent" suppliers are managed by one person - a structure created to extract margin.
