The application of accounting, auditing, and investigative skills to detect financial fraud, resolve disputes, and provide litigation support.

What is Forensic Accounting?

Forensic accounting combines accounting expertise with investigative techniques to examine financial records for evidence of fraud, embezzlement, money laundering, or financial misrepresentation. Forensic accountants are hired by law firms, corporations, government agencies, and insurance companies to investigate suspected fraud, support litigation, reconstruct financial records, trace hidden assets, and calculate economic damages. Key techniques include Benford's Law analysis (detecting anomalous patterns in numbers), financial statement fraud detection, tracing funds across accounts, and quantifying losses. Forensic accountants frequently serve as expert witnesses in court proceedings. The field has grown significantly following high-profile corporate fraud cases such as Enron and WorldCom, which led to increased regulatory scrutiny under the Sarbanes-Oxley Act.

Example

Example

After discovering unexplained cash shortfalls, a mid-size retailer hires a forensic accountant. The investigation uncovers a purchasing manager who created fictitious vendors, approved fraudulent invoices, and diverted $2.1 million over four years. The forensic accountant reconstructs the scheme through bank records, email evidence, and pattern analysis, providing expert testimony that leads to criminal charges.
