Civil Fraud — Our Services
Fraud Defence
Our experienced fraud defence team has acted for clients facing allegations of dishonesty and corruption, including claims for deceit, misrepresentation, conspiracy, breach of fiduciary duty and breach of trust.

We have extensive experience representing defendants facing proceedings in multiple jurisdictions or simultaneous criminal and civil proceedings. We have advised on hundreds of freezing and search orders, every kind of interim relief and in committal proceedings. No matter the complexity, we draw on our expertise and creative thinking to develop the right strategy for the client.

We understand the stress and strain fraud allegations can cause, so work hard to guide clients through each stage – representing their interests robustly, even in the face of the most powerful opposition.
