In a legal dispute, a forensic accountant investigates financial records to uncover fraud, trace concealed assets, measure economic losses, and translate complex money trails into evidence a court can rely on. Attorneys bring them in when the numbers matter and the truth is not obvious from a standard audit. What forensic accountants do in legal disputes depends on the case, but the work generally falls into three buckets: proving financial wrongdoing, quantifying damages, and finding what someone is trying to hide.
Investigating Fraud and Financial Crimes
In criminal cases and internal investigations, forensic accountants examine ledgers, bank records, and digital footprints to document schemes like embezzlement, money laundering, and wire fraud. They look for payments to fictitious vendors, manipulated payroll entries, and funds routed through shell companies or nominee accounts to disguise their origin.
Several analytical tools do this heavy lifting. Benford’s Law, a mathematical principle predicting how often each digit appears first in naturally occurring data, flags entries that look fabricated. Trend analysis surfaces red flags like unexplained jumps in wealth, frequent wire transfers to high-risk jurisdictions, or gaps between inventory records and physical counts. Forensic accountants also watch for structuring, the deliberate splitting of transactions to stay below federal reporting thresholds, since banks must file a Suspicious Activity Report for transactions of at least $5,000 they suspect involve illegal activity, and a Currency Transaction Report for cash transactions above $10,000 in a single business day.1Financial Crimes Enforcement Network.

In identity theft cases, they reconstruct a victim’s financial history to document the full extent of unauthorized credit applications and account takeovers. Throughout any investigation, they maintain a strict chain of custody for all evidence, documenting every step of collection, handling, and storage so the findings remain admissible.2National Institute of Justice.

Calculating Damages and Valuing Businesses
Civil cases often turn on a dollar figure, and that figure comes from a forensic accountant. In breach of contract, intellectual property, and personal injury disputes, they typically apply the “but-for” method: estimate what the plaintiff’s financial position would have been if the harmful event had never occurred, then compare that projection against actual results. The difference is the damages. To build the projection, they draw on historical revenue data, market trends, and industry benchmarks.
Patent cases add a specific wrinkle. Federal law requires that patent damages be “adequate to compensate for the infringement, but in no event less than a reasonable royalty” for the infringer’s use of the invention.3Office of the Law Revision Counsel. 35 U.S. Code 284 – Damages Forensic accountants calculate that royalty by examining comparable licensing agreements, the patent’s contribution to the infringing product, and the market position the patent holder lost.
Business valuation is another major piece of this work, used when partners disagree on what a shared company is worth or when insurance claims follow an event that halted operations. Three approaches are standard: an income approach (projecting future earnings), a market approach (comparing the business to similar companies that have sold), and an asset-based approach (tallying the fair value of what the business owns). Accountants adjust financial statements to strip out personal expenses or one-time items that would distort the company’s true profitability.
They also calculate prejudgment interest, which compensates for the time value of money between when the harm occurred and when judgment is entered. The applicable rate and method vary by jurisdiction, and in cases that drag on for years, this piece can add significantly to the final figure.
Finding Hidden Assets in Divorce and Estate Cases
When one spouse hides wealth from the other, or when an executor is suspected of draining an estate, forensic accountants are the ones who find the money. A core technique is the lifestyle audit: comparing a person’s reported income against their actual spending. If someone claims modest earnings but lives lavishly, the gap gets investigated.
Common hiding tactics include placing fictitious employees on a business payroll, running personal expenses through a company as deductions, transferring undervalued property to friends or family, and deliberately overpaying creditors to create refundable credits the hiding spouse plans to collect once the divorce is final. Forensic accountants also trace transfers to offshore accounts in secrecy jurisdictions, look for prepaid cards and cash hoarding, and in probate cases, review years of bank records to see whether an executor diverted funds from the deceased’s accounts. The findings directly shape how a court divides assets, under either equitable distribution or community property rules.
Tracing Cryptocurrency and Digital Assets
Cryptocurrency has made asset discovery harder. Unlike a bank account, a self-hosted crypto wallet cannot simply be subpoenaed. Forensic accountants combine on-chain analysis, examining the public blockchain ledger to follow transactions between wallets, with off-chain analysis, which pulls records from the exchanges where someone bought, sold, or transferred digital assets. Modern blockchain platforms increasingly use artificial intelligence to flag suspicious patterns across large transaction volumes.
How the Investigation Unfolds
Forensic engagements follow a structured sequence, though the duration swings widely with the volume of records and the complexity of the activity.
- Defining the scope with the attorney and client: which questions need answering, which records are relevant, and what outcome the work should support.
- Collecting financial documents: bank statements, accounting files, tax returns, credit card records, and anything else that moves the picture forward.
- Preserving digital evidence: using forensic software to create exact copies of computers, email accounts, cloud storage, and mobile devices in their original state.
- Organizing and analyzing the data: converting raw records into structured spreadsheets, categorizing transactions, and tracing the flow of money to see where it started, where it went, and whether it was diverted.
- Conducting interviews with owners, employees, bookkeepers, and vendors to understand processes and surface inconsistencies.
- Reporting findings in a detailed written report covering objectives, methodology, evidence reviewed, and conclusions, often with flow-of-funds charts and visual exhibits built for court.
- Presenting or testifying in a deposition or at trial when the case requires it.
Every step is documented. A break in the chain of custody, meaning a gap in the record of who handled the evidence and when, can cause a court to exclude the findings or discount their weight.2National Institute of Justice. Law 101 Legal Guide for the Forensic Expert – Chain of Custody
Supporting Discovery and Testifying as an Expert
During discovery, forensic accountants help attorneys pinpoint the financial documents that will actually move the case. Under the Federal Rules of Civil Procedure, a party can request documents, electronically stored information, and other tangible items relevant to the claims or defenses.4Cornell Law School. Federal Rules of Civil Procedure Rule 34 Forensic accountants draft targeted requests specifying the electronic databases, tax returns, and general ledgers most likely to be revealing. Once the records come in, they translate complex financial data into charts, graphs, and exhibits a judge or jury can follow.
Expert Testimony and the Daubert Standard
When a forensic accountant takes the stand as an expert, the methodology is tested before the jury hears a word. Under Federal Rule of Evidence 702, the party offering the testimony must show it is more likely than not that the expert’s knowledge will help the fact-finder, that the testimony rests on sufficient facts, that it is the product of reliable methods, and that the opinion reflects a reliable application of those methods to the case.5United States Courts. Federal Rules of Evidence This framework, rooted in the Supreme Court’s 1993 decision in Daubert v. Merrell Dow Pharmaceuticals, puts the trial judge in a gatekeeper role, weighing whether the techniques can be tested, have been peer-reviewed, have a known error rate, and are generally accepted. Roughly 38 states follow Daubert or a modified version of it, while a smaller number still use the older Frye “general acceptance” test.
On the stand, forensic accountants explain their findings in plain language, stay objective, and prepare for cross-examination by identifying weaknesses in the opposing side’s financial arguments.
Testifying Experts vs. Consulting Experts
Not every forensic accountant on a case will testify, and the distinction matters. A testifying expert is subject to full discovery: the other side can review the reports, take a deposition, and challenge the methods. A consulting expert, retained to help the legal team understand the financial issues without appearing at trial, is generally shielded from discovery. The opposing side usually cannot force them to produce documents or sit for a deposition, and that protection falls away only in exceptional circumstances where the requesting party has no practical way to get the same information elsewhere.6U.S. District Court for the Northern District of Illinois. Rule 26 of the Federal Rules of Civil Procedure
Keeping the Work Confidential
If you hire a forensic accountant directly, their work product and communications generally are not protected by attorney-client privilege. If an attorney hires the accountant to help provide legal advice, that protection can extend to the accountant’s work through what is known as a Kovel arrangement, named after a 1961 federal appellate decision.7Justia Law. United States v. Kovel, 296 F.2d 918 (2d Cir. 1961) Under a properly structured Kovel agreement, the accountant works at the direction and supervision of counsel, and confidential communications and work product receive the same protection that would normally apply only to attorney-client interactions. The workpapers typically belong to the attorney, which reinforces the privilege.
If you are facing a fraud investigation or a contentious divorce and want the analysis to stay confidential, having the attorney retain the accountant rather than hiring one yourself makes a meaningful difference. One caveat: if the accountant later testifies, much of the privilege falls away because opinions and supporting materials become subject to discovery.
Credentials, Standards, and What It Costs
When hiring a forensic accountant, look for recognized credentials. The Certified in Financial Forensics (CFF) designation is granted exclusively by the AICPA to CPAs who demonstrate expertise in areas like litigation support, bankruptcy, and family law financial analysis.8AICPA and CIMA. What Is the CFF Credential? The Certified Fraud Examiner (CFE) credential, issued by the Association of Certified Fraud Examiners, focuses specifically on fraud detection and prevention. Many practitioners hold both.
The AICPA’s Statement on Standards for Forensic Services governs how these professionals conduct engagements. They must maintain objectivity, establish a clear written or oral understanding of the engagement’s scope, and disclose any conflicts of interest. A forensic accountant serving as an expert witness cannot work on a contingent fee, meaning their pay cannot depend on the case’s outcome. The standards also prohibit them from offering an ultimate opinion on whether fraud occurred, since that call belongs to the judge or jury; they may testify about whether the evidence is consistent with the elements of fraud.9AICPA. Statement on Standards for Forensic Services
Fees depend on the complexity of the case and the volume of records. Most practitioners bill hourly, with rates for litigation support generally in the $300 to $500 range. Deposition and trial testimony tend to sit at the higher end. A straightforward engagement with limited records might come in at a few thousand dollars; a complex fraud investigation or high-asset divorce can run into six figures. Reputable firms provide a written engagement agreement laying out expected costs before any work begins.
