What Is Forensic Accounting? A Guide for Irish Businesses
Forensic accounting combines accounting, financial analysis and investigative techniques to examine financial disputes, suspected fraud and other complex financial matters. This guide explains how this specialist work is carried out, what a forensic accountant does and when businesses may need specialist support.
When money is in dispute, whether through a partnership breakdown, suspected fraud, a financial loss or figures challenged in court, specialist investigation can help establish what happened. Chartered accountants can examine the records, trace transactions and explain complex financial evidence clearly and independently.
Why chartered status matters here
In forensic work, credibility is everything: a report is only as strong as the professional standing behind it. McManus McCabe is a chartered practice: Teresa McCabe is a Fellow of Chartered Accountants Ireland and Adrian McManus a Fellow of the ACCA, with a combined 50 years in the profession. That chartered status, and the independence and professional standards it carries, is exactly what a court, a regulator or an opposing party expects of a forensic expert.
What Does a Forensic Accountant Do?
Corporate disputes and financial investigations, shareholder, partnership and commercial disagreements.
Personal disputes including matrimonial and family financial matters.
Investigation of losses or suspected fraud: tracing, quantifying and evidencing.
Litigation support: assisting solicitors and their clients with the financial elements of a case.
Independent expert witness: clear, impartial expert reports and testimony (see our expert witness page).
Alternative Dispute Resolution: financial analysis to support mediation and settlement.
How a Financial Investigation Works
- Scope: we define the question to be answered and the material available, and agree a written proposal.
- Gather: we collect and secure the relevant financial records and data.
- Investigate: we trace transactions, reconstruct records where needed, and analyse the numbers.
- Quantify: we calculate the loss, gain or disputed amount on a defensible basis.
- Report: we set out clear, independent findings; where required, in the form of an expert report for court.
- Support: we assist through mediation, settlement or hearing, including giving evidence as an expert witness.

What it costs and how we scope fees
We do not publish a single price because no two engagements are the same; the fee depends on the size and complexity of the business, the records available, and the scope agreed.
After an initial consultation, we issue a written proposal setting out exactly what is included, the timescale and the cost, so there are no surprises.
Where an engagement is likely to run in stages (for example an investigation or a multi-year succession), we scope and price each stage separately.
Discreet and independent
Forensic matters are sensitive. We work confidentially and independently. Our duty in expert work is to the facts and, where relevant, to the court, not to a predetermined answer. That independence is what makes our findings useful: they carry weight precisely because they are objective.
