California expert witness deposition fees depend on whether the charges involve attendance, preparation, travel, or related expenses. This article explains who pays each category, statutory tender requirements, the “reasonable and customary” standard, procedures for challenging excessive fees, and practical ways to manage deposition costs.
Expert depositions can become one of the larger line items in a California litigation budget. The issue is not just the hourly rate. It is also how time is counted, who pays for which category of time, and what happens when a demanded fee functions like a barrier to completing discovery.
California’s expert deposition fee rules are largely statutory. In general, the party taking the deposition pays for the expert’s deposition attendance time. The party who designated the expert pays the expert’s preparation time, travel time, and travel expenses.
This guide walks through the statutes that control expert deposition fees in California, how the law defines “reasonable and customary” compensation in this context, and how to handle disputes without creating avoidable motion practice.
A useful way to think about expert costs is two buckets: deposition attendance, and everything else.
For covered experts, the key provisions are in the California Code of Civil Procedure, including CCP §§ 2034.430 through 2034.470. California Government Code § 68092.5 also addresses expert compensation more generally and includes several concepts that overlap with deposition fee disputes. Importantly, it also notes that expert depositions are governed by the Code of Civil Procedure provisions on expert depositions.
Under California law:
CCP § 2034.430 is the core attendance-time rule. It applies to specific categories of experts, and it requires the party seeking the deposition to pay the expert’s reasonable and customary hourly or daily fee for time spent at the deposition.
The statute measures that time from the time noticed in the deposition subpoena, or from the expert’s arrival time if later, until the expert is dismissed. It also states that the fee is owed within that window regardless of whether the expert is actually deposed by any party attending the deposition.
The statute also addresses tardiness. If counsel for the expert or counsel for a non-noticing party arrives late, the statute shifts responsibility for the expert’s fee for the period from the noticed time until that late arrival to the tardy counsel. The amount charged to tardy counsel is capped, except in the specific situation where the expert has donated services to a charitable or nonprofit organization and is compensated only for testifying.
Finally, the statute limits when a daily fee may be charged. A daily fee is only permitted for a full day of attendance, or when the deposing party required the expert to be available for a full day and the expert necessarily had to forgo all business that day because of that requirement.
If you designated the expert, CCP § 2034.440 places responsibility for the expert’s fees for deposition preparation and travel on the designating party. That includes travel time to the deposition and the expert’s travel expenses.
This statute is short, but it matters in practice because it draws a clear line between the fee for attending the deposition and the time and expense involved in getting ready for it.
Tender is required by statute. CCP § 2034.450 requires the party taking the deposition to either include the tender with service of the deposition notice (based on anticipated length) or tender the fee at the commencement of the deposition. The statute also specifies that the expert’s fee is delivered to the attorney for the party designating the expert.
If the deposition takes longer than anticipated, CCP § 2034.450 requires the noticing party to pay the remaining balance within five days after receiving an itemized statement from the expert.
If the noticing party fails to tender the required fee, CCP § 2034.460 provides that the expert is not deposed at that time unless the parties stipulate otherwise.
When a demanded fee is disputed, CCP § 2034.470 provides a specific procedure to move for an order setting the expert’s deposition compensation. Notice of the motion must also be given to the expert, and the motion must include a meet-and-confer declaration under CCP § 2016.040.
That declaration should state the facts showing a reasonable, good-faith attempt to resolve each issue informally, whether the parties met in person, by phone, or by videoconference. It must also state whether the moving party met and conferred about retaining a certified shorthand reporter for the hearing, including through electronic communication.
The statute is evidence-driven. In an informal resolution attempt, the party or the expert must provide proof of the expert’s ordinary and customary fee actually charged and received for similar services outside the subject litigation. For actions filed after January 1, 1994, the statute also directs attention to how many times the presently demanded fee has ever been charged and received and how frequently and regularly it has been charged and received within the two-year period preceding the hearing.
The court may also consider what similar experts charge for similar services within the relevant community, along with any other factors the court deems necessary or appropriate. If the court determines the demanded fee is unreasonable, it must set the fee based on the evidence and factors considered.
The sanctions rule is also important. CCP § 2034.470 provides that the court must impose a monetary sanction against a party, person, or attorney who unsuccessfully makes or opposes the motion, unless the court finds substantial justification or that other circumstances make sanctions unjust. That structure is a practical reason to build a clean record before filing.

That structure is a practical reason to build a clean record before filing.
California’s expert deposition fee statutes rely on a “reasonable and customary” standard. In a fee dispute under CCP § 2034.470, the statutes require evidence of what the expert actually charges and actually receives for similar services outside the litigation, as well as comparable rates in the relevant community and other factors the court finds appropriate.
In plain terms, the best fee dispute record is specific. It uses billing history that shows what the expert has actually charged and received, and it uses comparable expert rates where that comparison is meaningful.
The statutes define who pays for categories of time and how a fee dispute can be resolved. They do not dictate an expert’s billing model, billing increments, minimum commitments, or engagement terms.
In practice, many teams manage risk by getting fee terms in writing early and confirming how the expert will bill for attendance time, preparation, travel time, travel expenses, and any minimum blocks. That step is not a legal requirement. It is a practical way to reduce avoidable surprises later.
The statutes allocate responsibility for categories of time, but they do not require a single billing approach. In many cases, disputes can start because the parties did not have a shared understanding of how time would be billed or documented.
For example, depending on the engagement terms, experts may bill in different increments, may require minimum blocks for a reserved deposition window, and may set retainer or cancellation terms. Those are contractual and practice-driven issues. They are not imposed by CCP §§ 2034.430 through 2034.470.
A fee dispute is often just a money dispute. Still, teams sometimes treat a fee dispute as a reason to reassess the engagement from a risk-management perspective.
For example, if an expert refuses to provide basic itemization for deposition attendance time versus preparation and travel, it can become harder to evaluate the fee under the statutory framework and harder to present a clean record to the court if a motion becomes necessary. Similarly, if a demanded fee is hard to reconcile with the expert’s documented billing history, the issue can shift from negotiation into a proof problem.
These are not legal conclusions, and the statutes do not require any particular inference. They are practical considerations about how a fee dispute can affect deposition logistics, motion risk, and the clarity of the record.
The statutory framework gives you clear requirements, but it also creates process steps that matter when a dispute arises.
Before scheduling, request a clear written fee schedule that addresses the categories the statutes care about, including deposition attendance time, preparation time, travel time, and travel expenses, plus any engagement terms that affect the total cost.
Preparation time is the designating party’s responsibility under CCP § 2034.440. If you are the designating party, planning and scope discipline can reduce avoidable spend.
Coordination is not a statutory requirement, but it can reduce scheduling friction and repeated logistics in cases where multiple parties seek the same deposition.
If you decide to challenge a demanded fee, build the record the statute calls for. That typically includes meet-and-confer efforts documented in a declaration under CCP § 2016.040, notice to the expert, and an exchange of evidence addressing the expert’s ordinary and customary fees actually charged and received for similar services outside the litigation. For actions filed after January 1, 1994, it also includes the additional proof categories CCP § 2034.470 describes, including the number of times the demanded fee has ever been charged and received and how frequently and regularly it has been charged and received during the two-year period before the hearing.
Can attorneys negotiate expert deposition fees?
Yes. Experts set their own rates, and counsel can negotiate terms before scheduling. If negotiation fails and the fee is disputed, CCP § 2034.470 provides a procedure to ask the court to set compensation.
Who pays an expert’s deposition fee in California?
The party taking the deposition pays the expert’s reasonable and customary fee for deposition attendance time. The party who designated the expert pays the expert’s fees for deposition preparation and travel, including travel time and travel expenses.
Can an expert refuse to appear if fees are not paid?
If the noticing party fails to tender the required fee, the expert is not deposed at that time unless the parties stipulate otherwise.
What can a party do if an expert’s fee is excessive?
A party may move under CCP § 2034.470 for an order setting compensation. The statute requires a meet-and-confer declaration and notice to the expert, and it directs the court’s analysis to specific evidence categories.
Do these rules apply to treating physicians?
Sometimes. CCP § 2034.430 applies to treating health care practitioners who are to be asked during deposition to express certain opinion testimony, including opinions about diagnosis, prognosis, or the reasons for treatment decisions. The statute does not include testimony requiring only the reading of words and symbols in medical records. If a treating physician is appearing only as a fact witness, different compensation rules may apply.
