Corporate Fraud Investigation
“You suspect fraud inside your own business. You need to know what happened, who was involved and what it cost, before you act.”

Corporate fraud investigation establishes whether fraud has occurred inside a business, who was involved and what it has cost. It is instructed when suspicion is real but proof is not yet there, and it is designed to produce evidence that survives a disciplinary hearing, a civil claim or a criminal referral.

Frequently Asked Questions
What counts as corporate fraud?+
Any dishonest act that causes loss to the business or gain to someone at its expense. In practice that usually means employee theft, false invoicing, expenses and payroll abuse, kickbacks from suppliers, undisclosed conflicts of interest, or falsified financial records.
Will the person under investigation know?+
Not unless you choose to tell them. Enquiries are planned so the subject and their colleagues remain unaware, which matters both for the integrity of the evidence and for avoiding disruption if the suspicion turns out to be unfounded.
Can the findings be used in a disciplinary or in court?+
That is what they are prepared for. Evidence is gathered lawfully and documented with a clear record of what was found and when, so it can support a disciplinary process, a civil claim, or a referral to the police.
How much does a corporate fraud investigation cost?+
It depends on scope: how many people and transactions are involved, how far back the concern goes, and whether surveillance is needed alongside the records work. We scope the work and give you a realistic cost before anything starts.
What should we do before instructing an investigator?+
Preserve what you already have and change as little as possible. Avoid confronting the individual, deleting or reorganising records, or discussing the concern widely, as each of those can compromise the evidence. A confidential conversation first is usually the safest next step.
