Corporate Fraud & Tax Investigations

If you suspect employee theft or corporate fraud, we conduct discreet internal investigations to trace stolen funds and secure the digital evidence needed for civil recovery or criminal prosecution.

Additionally, if your business is facing a severe tax inquiry, we handle complex HMRC tax dispute resolution. This includes managing Code of Practice 9 investigations and the Contractual Disclosure Facility to protect you from prosecution and negotiate a civil settlement.

CPR Part 35 Compliant Expert Witness Reports

A standard financial report will not hold up under cross-examination. UK civil courts require strict compliance with Civil Procedure Rules (CPR) Part 35.

Our forensic accountants deliver independent, legally watertight evidence that judges trust. We frequently act as a Single Joint Expert (SJE), saving you valuable court time and significantly reducing your overall legal costs.

Divorce & Matrimonial Asset Tracing

High net worth divorces often involve complex financial structures, offshore accounts, and family businesses. We help spouses and their instructing solicitors uncover the truth by:

  • Tracing hidden assets and analysing complex trusts.
  • Verifying Form E disclosures to ensure complete transparency.
  • Exposing concealed wealth or undervalued businesses to secure a fair, evidence based settlement.

Commercial & Shareholder Disputes

Partnership deadlocks and minority shareholder disputes can paralyse a business. We offer precise, objective business valuations to break the stalemate.

Whether you are dealing with a breach of contract, a disputed buyout, or a claim of minority shareholder prejudice, our forensic team quantifies the exact financial loss so you can negotiate from a strong position.

Secure Your Confidential Consultation

Do not leave your legal dispute to chance. Whether you are a solicitor seeking a CPR Part 35 expert or a business owner facing a financial crisis, contact our forensic expert for a discreet, objective review of your case.

    Some Commonly asked Question

    What is a CPR Part 35 expert report?

    Think of a CPR Part 35 report as a legally binding financial summary for a UK court. Because it follows strict Civil Procedure Rules, it guarantees that our forensic accountants provide 100% neutral and objective evidence, making your case highly credible to the judge.

    During a divorce, we make sure no wealth stays hidden. We dig into bank statements, tax returns, and complex company setups to spot unexplained transfers or offshore funds. Our goal is to uncover the complete truth, ensuring you have full transparency for a fair Form E financial settlement.

    Instead of each side hiring their own accountant, both parties agree to use one Single Joint Expert. This neutral approach is common in high-net-worth divorces because it significantly reduces costs and delivers a reliable financial baseline to settle the dispute.

    Because every case is not the same, the cost depends on how much financial history we need to untangle. Straightforward business valuations or asset tracing typically start between £3,000 & £5,000. For deep fraud investigations or complex court battles, fees can exceed £10,000. However, we know legal disputes are stressful enough without surprise bills. That is why we will always give you a clear, fixed-fee quote before we start any work.

    Yes. If HMRC suspects serious tax fraud and issues a Code of Practice 9 notice, our forensic accountants will conduct a comprehensive financial review, manage the Contractual Disclosure Facility and negotiate directly with HMRC to minimise penalties and help you avoid criminal prosecution.

    To figure out exactly what a business is worth, we look closely at its past success, current market standing, and future earning potential. We then apply court-approved valuation methods making fair adjustments for things like minority shareholdings if needed to give you a completely neutral, objective figure.

    Ultimately, our goal is to provide the rock-solid financial clarity you need to break a partnership deadlock or negotiate a fair buyout.
