How Can an Investor Tell When a Diligence Provider Has a Conflict of Interest?
Short answer. Ask how the provider is paid, who referred or hired them, whether compensation depends on a transaction closing, and whether they have other ties to the sponsor or asset. Compare the scope with the work performed, request disclosure of relationships, and seek a separate opinion when independence is unclear.
A diligence provider's incentives can shape what gets examined and how findings are presented. A conflict does not prove the work is biased, but you need to know who benefits before relying on it.
Map the Provider's Incentives
Ask who selected the provider, who pays, and whether any part of the fee depends on a transaction closing, assets moving, or a product being used. Ask about referral fees, equity, future assignments, and work for the sponsor, seller, manager, or an affiliated company. Request written disclosures that cover both the provider and its relevant affiliates.
Pay attention to platform incentives. A wealth advisor may recommend an investment that suits your goals and also keeps assets on its platform or generates revenue for the firm. In my experience, good advice can still carry an incentive that deserves to be understood. Ask what options were considered, including doing nothing, using another provider, or investing outside the advisor's platform.
Compare the Assignment With the Conclusion
Read the engagement letter or scope statement. Identify who chose the questions, which records the provider reviewed, who supplied those records, and what was excluded. A provider asked only to check a model's arithmetic has not assessed the investment thesis, ownership, or legal terms. The conclusion should not sound broader than the work performed.
Ask for the procedures performed and the evidence behind material findings. Reports that repeat sponsor claims without naming source records, skip exceptions, or offer a sweeping conclusion from a narrow review need follow-up. A referral from a trusted contact is not proof of independence, and a provider's reputation does not answer who controls the assignment.
Test the Relationship Directly
Ask these questions in writing:
- "Who chose and pays you, and does any fee or future work depend on closing?"
- "What work have you done for the sponsor, seller, manager, or an affiliate?"
- "Do you receive referral compensation, equity, or revenue from a recommended product or platform?"
- "Which records did you review, and what work was outside your scope?"
- "What finding would change your conclusion, and what remains unresolved?"
Check the answers against the engagement letter, invoices, referral disclosures, and report. If the provider recommends a product or service, request the alternatives considered and the basis for excluding options that produce no revenue for the provider.
Choose a Proportionate Response
For a material conflict, consider obtaining a separate opinion on the disputed point, changing the fee arrangement, or narrowing the provider's role. A second review is most useful when it tests a specific claim with access to the source records. If independence remains unclear or the provider will not disclose relevant relationships, do not treat its conclusion as independent evidence.
Record the conflict, scope limits, evidence reviewed, and the steps taken to address them. If the matter concerns legal or tax work, talk with your attorney or CPA about the professional standards that apply. For sponsor background checks and broader deal review, see the sponsor and GP due diligence checklist.

A skilled solution provider will only suggest things that legitimately make sense for you, but most will not want an in-depth solution about options that involve not working with them at all, even though that may be in your best interest.
