Questions to ask before a dispute, investigation or valuation matter progresses

If you are dealing with a dispute, investigation or matter under scrutiny, it is worth asking:

  • Do you have a clear and independent view of the financial facts?

  • Will your analysis stand up to detailed challenge or cross-examination?

  • Are valuations or loss calculations robust and defensible?

  • Is relevant data identified, preserved and reviewed effectively?

  • Are you reacting to issues, or proactively shaping your position?

If any of these are uncertain, early independent advice can materially influence the outcome.
