WHAT IS THE TYPICAL RETAINER FEE FOR EXPERT WITNESS CONSULTANTS?

When it comes to hiring an expert witness for a legal proceeding, one of the most common fee structures utilized is a retainer agreement. A retainer fee is an upfront, non-refundable deposit paid to engage the expert’s services and reserve their time for a case or matter. While retainer amounts can vary significantly based on factors like the expert’s credentials, field, location and the complexity of the assignment, there are some typical ranges that provide general guidance.

For a highly credentialed expert witness expected to conduct in-depth analysis, research, report writing and potential testimony, a common retainer fee could range from $10,000 to $50,000 or more. This upfront sum covers the initial time the expert allocates to become familiar with the key facts, review documentation, and begin their evaluation. It ensures their availability through at least the early phases of the matter.

For a straightforward case projected to require fewer hours from the expert, such as potentially just providing courtroom testimony after minimal preparation, a retainer fee between $2,500 to $10,000 is more typical.

In complex, high-stakes litigation matters like intellectual property disputes, antitrust issues, securities cases and other “bet the company” scenarios, retainers of $100,000 to $500,000+ are not unheard of when highly sought-after experts are needed to perform extensive analysis over many months.

The retainer fee paid is intended to cover only the initial upfront portion of the expert’s anticipated fees. Once that deposit is depleted based on their hourly or daily rate, additional payments for fees incurred are regularly invoiced throughout the engagement.

Beyond the professional fee retainer itself, advanced payment for potential expenses like travel, research costs, document fees and other reasonable disbursements is also commonly required upfront by expert witnesses.

While steep expert fees can add up, their specialized knowledge and ability to substantiate key positions through persuasive analysis and testimony is often worth the investment for attorneys in consequential legal matters. Setting proper expectations around retainer fees from the start helps ensure a productive expert-attorney working relationship.
