Hiring a forensic accountant for litigation requires matching the expert’s financial expertise, methodology, credentials, and litigation role to the specific issues in dispute. This article explains when forensic accountants may be useful, how attorneys can evaluate and structure the engagement, and the disclosure, Rule 702 admissibility, professional standards, and cost considerations that may apply.
Hiring a forensic accountant can be useful when a legal dispute involves complex financial records or transactions, suspected financial misconduct, asset tracing, valuation questions, or financial-loss calculations. The right expert depends on the financial issues and specialized skills the matter requires.
This guide explains when attorneys may consider retaining a forensic accountant, how to evaluate the engagement, and what disclosure, admissibility, professional standards, and cost considerations may apply.
A forensic accountant may be appropriate when a dispute requires specialized analysis of financial records or transactions.
Common assignments include:
Early involvement may also help counsel identify missing financial information before discovery or disclosure deadlines.
Before selecting an expert, counsel should identify the financial question the engagement is expected to address.
The initial scope may specify:
In federal civil litigation, that distinction can affect disclosure and discovery. Unless otherwise stipulated or ordered by the court, Rule 26(a)(2)(B) generally requires a written report for a witness retained or specially employed to provide expert testimony, as well as a party employee whose duties regularly involve giving expert testimony.
A consulting expert is treated differently. Under Rule 26(b)(4)(D), a party ordinarily may not use interrogatories or depositions to discover facts known or opinions held by an expert retained or specially employed by another party in anticipation of litigation or to prepare for trial and not expected to testify. The rule permits discovery as provided in Rule 35(b) or when exceptional circumstances make it impracticable to obtain facts or opinions on the same subject by other means.

The expert's experience should match the financial issues and opinions the expert is expected to address in the case. Credentials and years of experience should be considered alongside practical experience, methodology, and litigation role.
Determine whether the candidate has handled comparable fraud investigations, transaction tracing, damages analyses, valuations, or accounting reviews.
Credentials may include Certified Public Accountant (CPA), Certified in Financial Forensics (CFF), Certified Fraud Examiner (CFE), or other designations appropriate to the assignment. The relevance of a credential depends on the work the expert is expected to perform.
Ask how the expert will organize the analysis, verify source information, address incomplete records, evaluate assumptions, and document calculations.
Review the candidate's deposition and trial experience, relevant admissibility decisions, and any significant judicial criticism of the expert's methodology or opinions.
A testifying expert should be able to explain calculations, assumptions, limitations, and financial concepts clearly without overstating what the evidence establishes.
Counsel should identify potential conflicts and determine which professional standards apply to the expert's work on the engagement.
The records depend on the assignment. A forensic accountant may examine bank statements and other financial records, accounting records, and transaction-level data.
The analysis may include tracing transfers, comparing transactions, reconstructing financial activity, and calculating financial losses from the available records.
The expert should also be prepared to explain significant assumptions, missing information, and limitations affecting the analysis.
If a forensic accountant will testify in a federal civil action, counsel should consider the applicable disclosure rules. When the Federal Rules of Evidence apply, counsel should also consider the admissibility requirements for expert testimony.
Under Federal Rule of Evidence 702, a witness must be qualified as an expert by knowledge, skill, experience, training, or education. The proponent must also show the court, more likely than not, that the expert's specialized knowledge will help the trier of fact, that the testimony is based on sufficient facts or data, that it is the product of reliable principles and methods, and that the expert's opinion reflects a reliable application of those principles and methods to the facts of the case.
Unless otherwise stipulated or ordered by the court, a report required by Federal Rule of Civil Procedure 26(a)(2)(B) must include the opinions, their bases and reasons, facts or data considered, supporting exhibits, specified information about qualifications and prior testimony, and compensation. State-court requirements vary by jurisdiction.
Professional requirements depend on the expert's credentials, memberships, licensing, and engagement.
For example, AICPA describes its Statement on Standards for Forensic Services as applying to AICPA members and employees of member firms who provide services to a client as part of a litigation or investigation engagement, subject to the standard's stated scope and exceptions. Among other matters, it addresses professional competence, due professional care, planning and supervision, sufficient relevant data, integrity, objectivity, engagement scope, conflicts, and communication.
Except when the member serves as the trier of fact, the standards do not permit the member to give an opinion that fraud ultimately occurred. The member may still offer an expert opinion on whether the evidence aligns with specified elements of fraud or other law based on an objective evaluation.
Forensic accounting fees vary by engagement. Before retention, counsel should confirm the anticipated scope, rates, deliverables, and billing terms.
Organizing financial records and defining the assignment early can also help reduce unnecessary review.

When Should an Attorney Retain a Forensic Accountant?
An attorney may consider retention when a dispute requires specialized analysis of financial records, transactions, financial losses, valuation, or assets. Early involvement may also help identify needed financial discovery.

No. In federal civil litigation, Rule 26(a)(2)(B) generally requires a written report when the witness is retained or specially employed to provide expert testimony or is a party employee whose duties regularly involve giving expert testimony, unless otherwise stipulated or ordered by the court.
