In brief

Forensic accounting is accounting applied to a legal or investigative question. The U.S. Bureau of Labor Statistics describes forensic accountants as combining accounting and finance with law and investigative techniques, often working with lawyers and law enforcement and appearing as expert witnesses.1 This guide explains the main kinds of engagements, the usual process, the credentials and how the work differs from an audit.

Key points

  1. 01

    It starts with a question

    Every engagement is built around a specific question, such as where the money went or what a business really earns.

  2. 02

    Evidence beats assurance

    An auditor gives an opinion on financial statements; a forensic accountant follows the evidence and documents it for a court.

  3. 03

    Credentials vary

    CPA-based, fraud examiner and valuation credentials each fit different questions. Match the credential to the issue.

  4. 04

    Scope controls cost

    A clear question and organized records keep the engagement smaller and cheaper.

What is a forensic accountant?

A forensic accountant is an accounting professional who uses financial records as evidence. The BLS describes the specialty as investigating financial crimes such as securities fraud and embezzlement, bankruptcies, contract disputes and other complex and potentially criminal transactions, combining accounting and finance with law and investigative techniques to determine whether an activity is illegal.1

The ACFE puts it similarly: forensic accountants combine accounting knowledge with investigative skills in litigation support and investigative accounting settings. They trace funds and identify assets for recovery, analyze financial data, prepare reports and testify as needed. They work in public accounting firms’ forensic divisions, consulting firms, law firms, law enforcement, insurers, government and financial institutions.2

For CPAs who are AICPA members, the work is governed by the AICPA’s Statement on Standards for Forensic Services, which applies to litigation and investigation engagements and took effect on January 1, 2020.3 The BLS does not count forensic accountants separately; they fall within accountants and auditors, an occupation with a median annual wage of $83,680 in May 2025 and projected growth of 5 percent from 2025 to 2035.1

What do forensic accountants work on?

Most engagements fall into a handful of types. The records differ, but the method is the same: define the question, gather records, test them against independent sources and explain the result.

Fraud investigations

Embezzlement, vendor schemes, payroll fraud and financial statement manipulation. The examiner traces how money left, how it was concealed and how much was lost. Our guide to embezzlement explains the common schemes, and our business fraud and financial investigations practice handles this work for owners, boards and counsel.

Litigation support and damages

In commercial disputes, forensic accountants measure lost profits and other damages, test the other side’s numbers and support counsel in discovery. Large criminal cases also rely on this work; see how financial evidence was presented in the FTX prosecution and in Alex Murdaugh’s financial crimes case.

Divorce: income and assets

In a Florida divorce, the court considers any intentional dissipation, waste, depletion or destruction of marital assets after the petition was filed or within two years before it.4 Child support depends on gross income, and business income means gross receipts minus ordinary and necessary expenses required to produce income.5 Both put the numbers at the center. Our divorce asset and income analysis practice and the whitepaper on hidden assets in a Florida divorce cover this work; valuing the business itself is a separate task, explained in our guide to business valuation in divorce.

Insurance claims

Coverage for business interruption losses and related extra expenses is often included in property and casualty policies, and the policy defines the terms of coverage.6 Forensic accountants measure what the business would have earned had the event not happened.

Due diligence and regulatory matters

Before an acquisition or a loan, they test whether revenue, customers and collateral are real. Our whitepaper on verifying receivables and collateral applies this to lenders.

Exhibit 1Common forensic accounting engagements
EngagementThe question it answersTypical records
Fraud and embezzlement investigationWas money taken, how, by whom, and how much?Bank and card statements, general ledger, vendor and payroll files, emails, cancelled checks
Litigation support and damagesWhat did the breach or wrong cost, in lost profits or other damages?Financial statements, tax returns, budgets, contracts, industry data
Divorce: income and assetsWhat does each spouse really earn, what exists, and was anything dissipated?Tax returns, business records, bank and brokerage statements, financial affidavits
Insurance claimsWhat business income and extra expense did a covered event cause?Policy, monthly sales and expense history, payroll, repair and restart records
Due diligenceAre the target’s revenue, customers and assets real?Customer contracts, receivables detail, bank data obtained directly, shipping records
Regulatory and internal investigationsDid transactions comply with law or policy, and what must be disclosed?Transaction data, approvals, correspondence, policies, prior audit reports

Many matters combine several of these. A divorce involving a family business, for example, often needs both income analysis and a valuation by a credentialed appraiser.

How does a forensic accounting engagement work?

Most engagements follow the same arc, whether the matter is a theft from a small business or a contested divorce. The difference is scale.

Exhibit 2How a forensic accounting engagement usually runs
  1. 01

    Engagement

    Counsel or the client defines the question; conflicts are checked; scope, role (consulting or testifying) and budget are agreed in writing.

  2. 02

    Records

    A request list is issued; records come through disclosure, subpoena or the client; gaps are documented.

  3. 03

    Analysis

    Transactions are traced and tested against independent sources; income, assets or losses are reconstructed.

  4. 04

    Report

    Findings, methods, assumptions and limits are written up, with schedules a reader can check.

  5. 05

    Testimony

    If needed, deposition and trial testimony; the expert explains the work and answers the other side’s challenges.

Phasing the work lets counsel decide at each stage whether the next one is worth the cost.

The first decision is the role. A consulting expert advises counsel privately. A testifying expert prepares opinions that will be disclosed and challenged. The same person can start as one and become the other, but the choice affects what is written down and when.

If the work will be used in court, it must meet the rules on expert evidence. Federal Rule of Evidence 702, amended in 2023, requires the proponent to show the court that it is more likely than not that the testimony will help the trier of fact, rests on sufficient facts or data, is the product of reliable principles and methods, and reflects a reliable application of those methods to the case.7 Florida’s §90.702 applies the same three reliability requirements.8 Our whitepaper on preparing a financial expert under Rule 702 goes through them in detail, and our expert witness and litigation support practice covers testimony.

Which credentials matter?

There is no single license called “forensic accountant.” Practitioners hold a mix of accounting, fraud and valuation credentials, each issued by a different body.

CPA and CFF

The AICPA describes its Certified in Financial Forensics (CFF) credential as the premier designation for CPAs specializing in forensic accounting, covering fraud investigations, litigation support, commercial disputes, evidence gathering, expert reporting and professional standards.9 Applicants must be active AICPA members in good standing; the standard pathway requires at least 1,000 hours of forensic-related experience, 75 hours of continuing education within five years of application and a 175-question exam.10

CFE

The Certified Fraud Examiner credential is issued by the Association of Certified Fraud Examiners. Candidates must be ACFE members, reach at least 40 points for education and experience to sit the exam and 50 points to be certified, and have at least two years of professional experience related to detecting or deterring fraud. The exam covers fraud schemes and financial crimes, investigations and legal issues, and prevention and deterrence.11 Our guide to what a Certified Fraud Examiner is explains the credential in more depth.

CVA and MAFF

The National Association of Certified Valuators and Analysts issues the Certified Valuation Analyst (CVA) and the Master Analyst in Financial Forensics (MAFF). NACVA says both are accredited by the National Commission for Certifying Agencies, and that the MAFF requires prerequisites, an experience requirement and a five-hour proctored exam.12 A CVA matters most when the question is what a business is worth.

A credential is evidence of training, not proof of fit. Ask how often the person has done your kind of work, and whether a court has accepted their methods.

How is forensic accounting different from an audit?

People often assume that audited financial statements would have revealed a fraud. Usually they would not, and auditors do not claim otherwise.

Under PCAOB standards, the auditor plans and performs the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Absolute assurance is not attainable, so even a properly planned audit may not detect a material misstatement caused by fraud, and an audit is not designed to determine intent.13 The ACFE adds that auditors take a more consistent, standardized approach, while forensic accountants must decide which areas, people or functions need attention.2

Exhibit 3Forensic accountant versus financial statement auditor
DimensionFinancial statement auditorForensic accountant
PurposeOpinion on whether financial statements are fairly presentedAnswer a specific question for a dispute, investigation or decision
AssuranceReasonable assurance against material misstatement; absolute assurance is not attainableNo overall assurance; conclusions are limited to the question and the evidence examined
IntentAn audit is not designed to determine intentOften central: who acted, what they knew and how it was concealed
ApproachConsistent, standardized, risk-based testingFollows the evidence to the areas, people and functions that need attention
MaterialityFocus on amounts material to the statements as a wholeSmall items can matter if they show a pattern or an intent
Client and audienceThe company, its board and investorsUsually an attorney, a court, an insurer or a lender
OutputAudit opinionReport, schedules, exhibits and, if needed, expert testimony

Both roles require accounting knowledge. The difference is the question being asked and who relies on the answer.

The data bear this out. In the ACFE’s 2026 study of 2,402 occupational fraud cases, 43 percent were first detected by tips, and external audit was the initial detection method in about 2 percent.14 An audit is valuable, but it answers a different question.

When to hire one, and what to ask.

Bring in a forensic accountant when the answer to a legal or business problem depends on records you cannot interpret yourself, and earlier rather than later. Typical moments: when an owner first suspects theft, before a divorce petition is filed or answered, when a lender sees collections that do not match reported sales, when an insurer or policyholder disputes a loss, or when counsel needs to test the other side’s numbers before a deposition.

Searches for a “forensic accountant near me” are common, but location matters less than fit. Most records are electronic and much of the analysis is done remotely; what matters is experience with your type of matter and familiarity with the courts where it will be heard. Fraud Examination Service is a Florida-licensed investigation agency and works with attorneys, businesses and individuals on matters in Florida courts.

Exhibit 4Questions to ask before you hire a forensic accountant
  • Have you handled this type of matter before, and how many times in the last five years?
  • Which credentials do you hold (CPA, CFF, CFE, CVA, MAFF or others), and which are relevant to this question?
  • Have you testified, in which courts, and has your testimony ever been limited or excluded?
  • Do you have any conflict with the parties, their businesses or the other side’s counsel?
  • Will you work as a consulting expert, a testifying expert, or both, and how will that be documented?
  • Who will actually do the work, and what will you need from us first?
  • How will you scope and phase the engagement, and how will you report costs as it proceeds?
  • If the question needs a business valuation, a tax opinion or an audit, who will provide it?
  • Can you show an anonymized example of a report or schedule you have prepared?

Good answers are specific. Be cautious of anyone who promises a result before seeing the records.

Cost depends mostly on the question, the condition of the records and whether testimony is needed. Our guide on what a forensic accountant costs explains how engagements are priced and how to keep them proportionate. If you are dealing with suspected fraud in a company, start with our business investigations practice.

Common questions.

Short answers. The numbered notes link to the sources.

A forensic accountant examines financial records to answer a question in a dispute or investigation: whether money was stolen, where it went, what a business or spouse really earns, or how much a loss is worth. They trace transactions, reconstruct income and assets, quantify damages, write reports and, when needed, explain the findings to a judge or jury as an expert witness.

No. An auditor gives an opinion on whether financial statements are fairly presented, with reasonable assurance against material misstatement, and is not designed to determine intent. A forensic accountant is hired to answer a specific question, usually for a lawsuit or investigation, follows the evidence wherever it leads and prepares findings that can be used in court.

Not always. Many forensic accountants are CPAs, and the AICPA’s Certified in Financial Forensics credential is designed for CPAs. Others are Certified Fraud Examiners, valuation analysts or former investigators. What matters in court is whether the person is qualified by knowledge, skill, experience, training or education and uses reliable methods on sufficient facts or data.

Hire one when the answer to a legal or business problem depends on financial records you cannot interpret yourself: suspected embezzlement, a divorce where income or assets may be hidden, a commercial dispute over lost profits, an insurance claim for business interruption, or due diligence on a company whose numbers look too good. Earlier is cheaper than later.

Most forensic accountants bill by the hour, and the total depends far more on the question, the volume and condition of the records and whether testimony is needed than on the hourly rate. A narrow, well-documented question can be answered in a limited engagement; a multi-year reconstruction for trial takes much longer. Ask for a phased scope and budget.

Location matters less than fit, because most records are electronic and much of the work is done remotely. What matters is experience with your type of matter, familiarity with the courts where the case is pending, credentials that fit the question and no conflict of interest. Ask for prior testimony and a sample of how they present findings.
