Expert witness fees may be taxed as costs in Florida litigation when statutory requirements, reporting deadlines, necessity standards, and supporting documentation are satisfied. This article explains which expert expenses may be recoverable, how testimony and dismissals affect cost requests, and why federal courts apply different cost-taxation rules.
Expert witness fees can become a significant litigation expense, especially when expert analysis is central to the dispute. By the time litigation ends, those invoices may affect settlement discussions, client expectations, and the final cost recovery strategy.
That can be especially true in expert-heavy matters, such as cases involving medical causation, engineering, construction defects, valuation, accounting, product liability, insurance disputes, or technical damages. When the expert’s work is central to the case, attorneys often want to know whether some of those costs can be shifted after the case is resolved.
In Florida state court, expert witness fees may sometimes be taxed as costs. But they are not automatically recoverable just because a party hired an expert, paid an expert, or relied on the expert during case preparation.
The real questions are more practical: Was the expert used in a way Florida law recognizes? Was the required report provided on time? Was the expert’s work reasonably necessary? Is the amount supported by clear billing and a credible explanation?
This guide explains how expert witness fee taxation works in Florida, what attorneys should document, and why early planning can make a real difference when seeking to recover litigation costs.
Yes, but only when the request fits Florida law.
Under Florida Statutes § 92.231, an expert or skilled witness who testifies may be awarded a witness fee, including exhibit charges, in such amount as the court determines to be fair and reasonable, and that fee can be taxed as costs.
That statute is only the starting point for the analysis. A party still has to make a proper motion or request for costs and support the fee under the applicable statutes, procedural rules, cost guidelines, and the court’s review.
Florida Statutes § 57.071 adds another requirement that attorneys should not overlook. Section 57.071 generally provides that expert witness fees may not be awarded as taxable costs unless the retaining party gives each opposing party a signed written report. The report must summarize the expert’s opinions, the factual basis and reasons for those opinions, the documentary evidence relied upon, and the authorities relied upon.
In practical terms, the party seeking reimbursement should be ready to show three things: the rules were followed, the expert’s work was reasonably necessary, and the amount requested is supported by clear documentation.
This is why expert fee recovery should not be treated as an afterthought. A strong expert may help the case on the merits, but a strong fee request depends on the record counsel builds along the way.

This is why expert fee recovery should not be treated as an afterthought. A strong expert may help the case on the merits, but a strong fee request depends on the record counsel builds along the way.
The report requirement gives opposing parties a clear basis to challenge a motion for costs if the report is missing, late, incomplete, unsigned, or too vague. Under Florida Statutes § 57.071, the retaining party must provide a signed expert report that summarizes:
Timing matters too. The report must be furnished to each opposing party at least five days before the expert’s deposition or at least 20 days before the discovery cutoff, whichever is sooner, unless the court sets a different deadline. This report requirement does not apply to actions under the Florida Family Law Rules of Procedure.
This requirement can matter during a cost hearing. If the report is late, unsigned, incomplete, or does not meaningfully address the required opinions, factual basis and reasons, documentary evidence, and authorities relied upon, the opposing party may have a stronger argument against taxing the expert’s fees as costs.
For example, a signed report that explains an engineer’s defect opinions, inspection findings, photographs reviewed, testing data, and technical standards relied on will usually create a clearer record than a brief letter that only says the expert reviewed the file and reached opinions. The report does not have to decide the case for the judge or jury, but it should give the opposing party and the court enough information to understand what the expert is saying and why.
A timely signed report is important, but it does not guarantee recovery by itself. The court may still look at how the expert was used, whether the work was necessary, and whether the requested amount is properly supported.
Testimony usually makes the request stronger. That may include court testimony, deposition testimony, or work clearly tied to a testifying expert.
Section 92.231 refers to an expert or skilled witness who testifies. Florida’s Statewide Uniform Guidelines for Taxation of Costs are advisory guidelines that help courts categorize expert-related costs. The Guidelines identify reasonable fees for deposition or court testimony as categories of costs generally considered taxable, but the moving party still has to support the request and the court retains discretion in determining whether the requested costs should be taxed. Other testifying expert-related costs, such as certain examinations, investigations, tests, research, report preparation, and preparation for deposition, court-ordered nonbinding arbitration, or court testimony, fall into categories of costs that courts may consider taxable.
Those guidelines were amended by the Florida Supreme Court effective January 1, 2023, and they identify certain testifying expert witness costs and related work as categories of costs that courts may consider taxable. The Guidelines help courts categorize costs, but they do not make every listed expert expense automatic. The moving party still needs to support reasonable necessity and show that the requested fees fit the applicable cost category.
The harder question usually involves work done behind the scenes. Consulting work may be valuable to the legal team, but not every valuable litigation expense becomes a taxable cost. When the record does not connect the expert’s work to testimony, deposition, a qualifying report, or a recoverable expert-related cost category, fee recovery becomes harder to support.
For example, an accounting expert who prepares damages opinions, sits for deposition, and testifies at trial creates a much stronger cost record than a consulting expert who reviews records internally but never issues a report, never testifies, and is not clearly tied to a necessary litigation step.
Courts focus on whether the requested expert costs were reasonably necessary when they were incurred. The moving party generally carries the burden of showing that the requested expert costs were reasonably necessary to prosecute or defend the case.
Expert-related costs are usually stronger when they are tied to:
Fee requests are more vulnerable when the moving party cannot show that the requested cost was reasonably necessary, reasonable in amount, and tied to a recoverable expert-related cost category.
For example, an invoice that separates site inspection, testing, report preparation, deposition preparation, and testimony gives the court a clearer basis for review. By contrast, billing entries such as “case review,” “file work,” or “trial prep” may invite objections if they do not explain what the expert did or why the work was tied to a recoverable cost.
At a cost hearing, a clear record helps the moving party explain why the expert’s work was necessary and why the amount requested is reasonable.
Dismissals can complicate cost recovery because the court may need to understand which expert expenses relate to the dismissed claim and which expenses relate to claims that remain pending.
Florida Rule of Civil Procedure 1.420(d) deals with costs after an action or claim is dismissed. The rule provides that costs in an action dismissed under the rule must be assessed and judgment for costs entered once the action is concluded as to the party seeking taxation of costs.
If other claims remain pending, the timing of a cost request may depend on whether the action has been concluded as to the party seeking taxation of costs.
This can matter when a dismissal resolves only part of the case, when a voluntary dismissal is filed, or when multiple claims or parties affect when the action is concluded as to the party seeking costs. A party seeking expert costs should be ready to explain which costs relate to which claims and why the timing of the request is proper.
For example, if an expert analyzed only a dismissed construction defect claim while other contract claims remain pending, counsel may need to separate those costs carefully. A broad motion for costs that does not separate claim-specific expenses may be easier for the opposing party to challenge.
Yes. Florida state cost-taxation rules do not automatically control expert fee recovery in federal court.
Under Federal Rule of Civil Procedure 54(d), costs other than attorney’s fees generally may be allowed to the prevailing party unless a federal statute, rule, or court order provides otherwise. Federal taxable costs are governed by 28 U.S. Code § 1920, and witness attendance fees are governed by 28 U.S. Code § 1821.
The U.S. Supreme Court has made clear that federal courts cannot exceed those statutory limits without explicit statutory or contractual authority. That means fees for a party’s own retained expert witnesses may be treated more narrowly in federal court than under Florida state cost-taxation rules.
That difference can matter when a case is removed to federal court or when a Florida dispute begins in federal court. Attorneys should not assume that Florida state cost logic will carry over automatically.
Separate contractual provisions or explicit statutory authority may also affect recovery, so attorneys should review the governing language before assuming expert fees are recoverable.
For Florida litigators, this distinction is important. Expert fee recovery can look very different depending on whether the case is in Florida state court or federal court.
The best time to protect a later fee request is while the expert is still doing the work. Waiting until the case is over often leaves counsel trying to reconstruct details that should have been documented earlier.
Attorneys can put a later fee request in a stronger position by building a clear record from the beginning.
Key steps include:
A strong motion for costs should not leave the court guessing. The clearer the record, the easier it is to explain why the expert’s work was necessary and why the requested amount should be taxed.
Are all expert witness fees recoverable in Florida?
Not automatically. The party seeking reimbursement still has to show that the expert’s work fits the applicable rules and was reasonably necessary for the case.
What mistake can make expert fee recovery harder?
One common mistake is waiting until the end of the case to think about cost recovery. If counsel fails to furnish a proper signed report or misses the timing requirements, expert fee recovery becomes much harder to support. Vague invoices can create a separate documentation problem.
Can a consulting expert’s fees be taxed as costs?
Work performed only for internal consultation is usually harder to recover as a taxable cost, especially when the record does not connect the work to testimony, deposition, a qualifying report, or reasonably necessary work by a testifying expert. Fees tied to testimony, deposition, a qualifying report, or documented work by a testifying expert are usually stronger candidates for taxation.
Can the opposing party challenge expert witness fees?
Yes. The opposing party may argue that the expert was unnecessary, the report was late or incomplete, the fees were excessive, or the billing records do not support the amount requested.
Do the same rules apply in federal court?
No. Federal courts apply federal cost-taxation rules, including Rule 54(d), 28 U.S. Code § 1920, and 28 U.S. Code § 1821. In the expert-witness-fee context, a contract or explicit statutory authority may change the analysis.
Is there a deadline to request taxable costs in Florida?
Yes. Florida Rule of Civil Procedure 1.525 generally requires a party seeking costs, attorneys’ fees, or both to serve a motion no later than 30 days after the filing of the judgment or service of a voluntary dismissal notice that concludes the action as to that party.
