Financial forensic engagements may fall into several categories. For examples:

• Economic damages calculations, whether suffered through tort or breach of contract;
• Post-acquisition disputes such as earnouts or breaches of warranties;
• Bankruptcy, insolvency, and reorganization;
• Securities fraud;
• Business valuation; and
• Computer forensics/e-discovery.

Forensic accountants often assist in professional negligence claims where they are assessing and commenting on the work of other professionals. Forensic accountants are also engaged in marital and family law of analyzing lifestyle for spousal support purposes, determining income available for child support and equitable distribution.
Engagements relating to criminal matters typically arise in the aftermath of fraud. They frequently involve the assessment of accounting systems and accounts presentation—in essence assessing if the numbers reflect reality.
Some forensic accountants specialize in forensic analytics which is the procurement and analysis of electronic data to reconstruct, detect, or otherwise support a claim of financial fraud. The main steps in forensic analytics are (a) data collection, (b) data preparation, (c) data analysis, and (d) reporting. For example, forensic analytics may be used to review an employee's purchasing card activity to assess whether any of the purchases were diverted or divertible for personal use.
