Expert Witness & Litigation Support for Litigants and Attorneys

Whether you are an attorney building a case or a litigant trying to understand what strong financial testimony requires, expert witness work should begin with clear questions, usable records, and a defensible theory.

What to Gather Before an Expert Witness Engagement Begins

Whether you are a litigant preparing your own financial records or an attorney organizing discovery, the quality of an expert witness engagement depends on what goes in. Incomplete records delay analysis and weaken opinions. These are the documents and materials that matter most at the outset of any financial expert engagement:

  • Tax returns (federal and state, 3–5 years) — essential for income analysis, business valuation, and damages calculations in virtually every financial dispute
  • Financial statements and general ledger — audited or compiled statements, trial balance, and transaction-level detail for the periods at issue
  • Bank and credit card statements — used to trace cash flows, verify reported income, and identify unreported transactions
  • Contracts and agreements — operating agreements, shareholder agreements, partnership documents, and any contract central to the dispute
  • Prior appraisals or valuations — any previous business valuation, real estate appraisal, or damages study related to the matter
  • Opposing party’s financial disclosures — damages models, financial schedules, or valuations produced in discovery, if available
  • Case-specific records — payroll records, customer revenue files, insurance claim documents, or any financial record directly tied to the claims at issue

Expert Witness FAQ for Attorneys

When should I retain an expert witness CPA?

Retain a financial expert as early as possible — ideally at or before the discovery phase. Early retention allows the expert to shape document requests, identify the key financial records needed, flag weaknesses in the damages theory before depositions are taken, and allow adequate time to prepare a thorough, well-documented Rule 26 report. Late retention compresses timelines and can limit the scope and defensibility of opinions. For forensic accounting matters involving suspected fraud or embezzlement, early engagement is especially critical to preserve the chain of analysis.

What documents should I provide to the expert?

At a minimum, plan to produce: federal and state tax returns (3–5 years), audited or compiled financial statements, general ledger and trial balance, bank and credit card statements, contracts and key agreements at issue, corporate governance documents (operating agreements, shareholder agreements), any prior appraisals or valuations, and the opposing party’s damages model if produced in discovery. The expert will issue a formal document request list at engagement outset tailored to the specific matter. For complex economic damages claims, industry data, marketing records, and customer-level revenue files may also be required.

Should business valuation and damages be separate engagements?

In most litigation contexts, yes — business valuation (determining the fair market or fair value of a business interest) and economic damages (quantifying lost profits or lost business value as a result of a specific wrong) are analytically distinct engagements with different methodologies, standards, and scopes. Combining them into a single engagement can blur the opinions and create admissibility vulnerabilities. Where a case requires both a valuation opinion and a damages opinion, the expert should clearly define the scope of each opinion, the applicable standard of value, and the relevant measurement date for each. Contact the firm to discuss how to scope your specific matter.

Frequently Asked Questions

Litigation support refers to professional financial and accounting assistance provided to attorneys during the course of a legal dispute. Services include expert report preparation, financial analysis, deposition preparation, trial testimony, and consulting on financial aspects of the case. The goal is to give counsel the analytical foundation and expert voice needed to advance or defend financial claims effectively.

At minimum, a financial expert witness should hold a CPA license and relevant litigation credentials such as ABV (Accredited in Business Valuation) or CFF (Certified in Financial Forensics). Prior experience preparing Rule 26 expert reports, surviving depositions, and testifying at trial or arbitration is essential. Joey Friedman, CPA/ABV meets all of these standards.

A Daubert challenge is a motion to exclude expert testimony on the grounds that the methodology is unreliable or the expert is unqualified. To defend against it, the expert must demonstrate: (1) the opinion is based on sufficient facts or data; (2) the method is professionally or scientifically accepted; and (3) the method was reliably applied to the case facts. Rigorous documentation, recognized standards, and transparent assumptions are the strongest defenses.

As early as possible — ideally at or before the discovery phase. Early retention allows the expert to shape document requests, identify key financial records, flag weaknesses in the damages theory before depositions, and maximize preparation time for a thorough Rule 26 report. Late retention compresses the work timeline and may limit the scope and defensibility of the final report.

Yes. While the firm is based in Florida (Pembroke Pines / South Florida), Joey Friedman, CPA/ABV accepts engagements in matters pending in other states and federal courts nationwide. Depositions can often be handled remotely. Trial appearances are scheduled based on the jurisdiction and case calendar. Contact the firm to discuss your specific matter.

Common document requests include: federal and state tax returns (3–5 years), audited or compiled financial statements, general ledger and trial balance, bank and credit card statements, contracts and key agreements at issue, corporate governance documents, prior appraisals, and the opposing party’s damages model (if produced). The specific list is tailored to the scope of each engagement.

Expert witness fees are charged on an hourly basis for all phases — document review, report preparation, deposition, and trial testimony. Contingency fee arrangements are ethically prohibited for expert witnesses because they create a conflict of interest that undermines credibility. Attorneys should budget for report preparation, as well as deposition and trial hours, which vary with case complexity.

A consulting expert works behind the scenes advising counsel and is generally protected from discovery. A testifying expert’s opinions, methodology, and work product are subject to disclosure requirements (typically FRCP Rule 26 in federal court). Attorneys sometimes retain a consulting expert to evaluate the opposing expert’s report while reserving a separate professional for testimony to maximize strategic flexibility.
