Yes, expert witnesses do get paid, and they are paid well. The party that hires the expert covers the bill, and rates commonly run between $250 and $600 per hour for preparation work, with courtroom testimony billing higher and top specialists charging well above $1,000 an hour. That pay structure sets expert witnesses apart from ordinary fact witnesses, who receive only a small statutory attendance fee.
Who Pays the Expert
The side that retains the expert pays the expert. A plaintiff who needs a medical specialist to explain the extent of an injury pays for that testimony out of the litigation budget. A defendant who hires a forensic accountant pays that accountant. The arrangement is set out in a retainer agreement between the law firm and the expert, and the client ultimately absorbs the cost as part of the case expenses.
When the federal government calls an expert, the fee is negotiated directly between the government attorney and the expert and paid from the Department of Justice’s dedicated witness appropriation.1Department of Justice. Fees and Expenses of Witnesses – FY 2018 Congressional Submission
How Much Expert Witnesses Charge
Most experts bill by the hour, and the rate varies by the type of work. Industry surveys covering tens of thousands of cases show a consistent tiered pattern: case review and preparation sit at the bottom, deposition testimony in the middle, and live trial testimony at the top. Recent survey averages come in around $356 per hour for case review, $448 per hour for depositions, and $478 per hour for trial testimony. Those figures blend every field together. A biomechanical engineer analyzing crash data and a Nobel-laureate economist testifying about market damages occupy very different price ranges.
The expert’s field is the biggest single driver of the rate. Medical specialists, and surgeons in particular, routinely charge more than professionals in less specialized disciplines. Beyond specialty, an expert’s track record, the complexity of the case, and the total time commitment all move the number. Some experts price discrete tasks like report writing as a flat fee; others bill everything hourly.
Retainers
Most engagements begin with a retainer, an advance deposit the expert draws against as work is performed. Retainers commonly cover roughly one month of expected billing. If the case wraps up with unused funds, the balance is typically refunded to the firm. The retainer protects the expert from nonpayment and gives the hiring attorney a clear cost commitment up front.
Travel and Other Reimbursable Expenses
Professional fees are not the whole bill. Expert witnesses routinely charge for travel on top of their hourly rates. Airfare, rental cars, hotels, and meals during travel are standard reimbursable items. Some engagements use a per diem for meals and incidentals rather than requiring the expert to submit each receipt. Experts with niche practices may also bill for specialized materials, testing, or equipment needed to reach their opinions. The engagement agreement should spell out which expenses are covered and how they will be documented.
Contingency Fees Are Not Allowed
An expert’s pay cannot depend on the outcome of the case. No bonus for a favorable verdict, no cut of a settlement. The common law rule in most jurisdictions prohibits contingency fee arrangements with expert witnesses, and the American Bar Association’s official commentary on Model Rule 3.4 states directly that paying an expert a contingent fee is improper.2American Bar Association. Model Rules of Professional Conduct – Comment on Rule 3.4 Fairness to Opposing Party and Counsel Rule 3.4(b) prohibits lawyers from offering any inducement to a witness that is prohibited by law.3American Bar Association. Model Rules of Professional Conduct – Rule 3.4 Fairness to Opposing Party and Counsel An expert with a financial stake in the verdict has an incentive to shade opinions, and violating the prohibition can get the testimony thrown out and expose the attorney to discipline.
Who Pays When the Other Side Deposes Your Expert
If opposing counsel wants to depose your expert, they generally have to pay for the expert’s time. Federal Rule of Civil Procedure 26(b)(4)(E) requires the party seeking expert discovery to pay the expert a reasonable fee for time spent responding, unless doing so would be manifestly unjust.4Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery A “reasonable fee” means the expert’s normal deposition rate, not a discount.
Can You Recover Expert Fees If You Win?
In federal court, the prevailing party generally cannot recover the full cost of expert witnesses. The taxable costs a winning party can claim for witnesses are capped at the statutory attendance fee of $40 per day set by 28 U.S.C. ยง 1821, not the expert’s actual professional rate.5Office of the Law Revision Counsel. United States Code Title 28 Section 1821 – Per Diem and Mileage Generally The Supreme Court confirmed the limit in Crawford Fitting Co. v. J.T. Gibbons, holding that federal courts cannot tax expert fees beyond the statutory per diem unless a specific statute or contract authorizes it.6Legal Information Institute. Crawford Fitting Co. v. J.T. Gibbons, 482 U.S. 437
If you spend $50,000 on an expert during the case, winning does not mean the other side reimburses you. The recoverable portion is the $40 per day plus travel. A few federal statutes create narrow exceptions for specific case types, and state courts vary, with some allowing fuller recovery. Plan for expert fees as a sunk cost rather than an expense you will recoup.
Your Expert’s Fees Will Be Disclosed
In federal litigation, the other side will learn what you are paying. Federal Rule of Civil Procedure 26(a)(2)(B) requires every retained expert’s written report to include a statement of the compensation being paid for study and testimony in the case.4Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery Opposing counsel uses that information at deposition and trial, asking how much the expert is earning, how often they testify for the same firm, and what share of their income comes from expert work. The goal is to suggest a hired gun whose opinions follow the money.
How Fact Witnesses Are Paid Differently
The gap between expert pay and fact witness pay is enormous. A fact witness, someone who testifies about events they personally observed, does not receive a professional fee. Giving that testimony is treated as a civic obligation, similar to jury duty. In federal court, the fee is $40 per day of attendance, plus reimbursement for travel costs like mileage, tolls, and parking.5Office of the Law Revision Counsel. United States Code Title 28 Section 1821 – Per Diem and Mileage Generally State courts set their own rates, typically between $5 and $35 per day. An expert billing $478 an hour for trial testimony and a fact witness receiving $40 for the whole day show how differently the system values specialized knowledge and firsthand observation.
