Forensic Accounting Firms Specializing in Litigation Support
The forensic accounting services market in the United States comprises over 5,500 firms, ranging from Big Four advisory divisions to specialized boutique practices. Globally, the market reached approximately $7 billion in 2025 and is projected to exceed $11 billion by 2030, driven by rising regulatory scrutiny and increasingly complex financial disputes.
What Litigation Attorneys Need from Forensic Accountants
Effective litigation support goes beyond basic number-crunching. The most valuable forensic accounting partners bring three critical capabilities to a case:
- Expert Witness Credibility
- Courts assess expert testimony under Daubert or Frye standards. Firms with former SEC enforcement staff or DOJ prosecutors — such as Ankura and FTI Consulting — carry particular weight in federal proceedings.
- Financial Damage Quantification
- Lost profits, business interruption, and intellectual property damages require defensible methodologies. Firms like MDD and Berkeley Research Group (BRG) maintain dedicated damages practices with track records across 800+ industries.
- Investigative Depth
- Fraud investigations demand forensic data analytics, asset tracing, and financial record reconstruction. Kroll and Secretariat combine traditional forensic accounting with digital forensics and cross-border investigative capabilities.
Big Four vs. Boutique: Choosing the Right Fit
Big Four firms (Deloitte, PwC, EY, KPMG) offer deep bench strength and global reach but can present conflict-of-interest issues in cases involving their audit clients. Mid-market firms like BDO, Baker Tilly, and CLA provide strong forensic practices without the same conflict exposure. Boutique specialists — StoneTurn, Fox Forensic Accounting, BERO Group — offer niche expertise and often more competitive rates, particularly for matters under $10 million in dispute.
