How much arbitration costs in California depends on who you are. An employee or consumer forced into arbitration by a signed agreement usually pays between $250 and $400 in filing fees and nothing more, because California law requires the employer or business to cover the rest. Two businesses arbitrating a commercial dispute typically split costs that can run from several thousand dollars for a short case to tens of thousands once arbitrator hours, administrative charges, and multi-day hearings add up.
Filing and Administrative Fees
Every arbitration begins with a filing fee paid to the organization that administers the case. The two largest providers in California are JAMS and the American Arbitration Association (AAA).
JAMS charges a $2,000 filing fee for a standard two-party case and $3,500 when three or more parties are involved. It also adds a case management fee equal to 13% of all professional fees, which covers scheduling, document coordination, and general administrative work throughout the case.1JAMS.

AAA’s commercial fee schedule is tiered by claim amount, so a bigger claim carries a higher administrative fee. AAA publishes an online calculator that estimates the charges based on claim size and the applicable rules.2AAA-ICDR.

Arbitrator Hourly Fees
The arbitrator’s professional fee is almost always the single largest line item. It covers time spent reviewing briefs and evidence, presiding over hearings, and drafting the final award. California arbitrators are typically experienced attorneys or retired judges, and JAMS sets hourly rates individually rather than publishing a fixed schedule.1JAMS. Arbitration Schedule of Fees and Costs Rates commonly run between $400 and $1,000 or more per hour, depending on the arbitrator’s background and the complexity of the dispute.
Some commercial contracts call for a three-arbitrator panel instead of a single neutral. According to AAA, a three-arbitrator panel can cost roughly five times what a single arbitrator charges, because three professionals are being paid for every hour of hearing time, reading, and deliberation. If you have any say in drafting or amending an arbitration clause, the single-versus-panel choice drives more cost variation than almost anything else in the agreement.
What Employees and Consumers Actually Pay
California law draws a hard line between commercial arbitrations and those involving employees or consumers. If you signed an arbitration agreement as a condition of employment or as part of a consumer transaction, you are not expected to bear the full cost of the process.
The California Supreme Court’s decision in Armendariz v. Foundation Health Psychcare Services, Inc. held that an employer who requires arbitration as a condition of employment must pay all arbitration costs the employee would not have incurred in court.3Justia. Armendariz v Foundation Health Psychcare Services Inc The reasoning is simple. If the employer chose private arbitration over the public court system, the employee shouldn’t pay extra for that choice. Courts have extended the principle to consumer arbitrations, where the business that drafted the arbitration clause bears the costs.
At JAMS, a consumer pays no more than $250 to file, and an employee pays no more than $400. Everything else, including the arbitrator’s full hourly fee and all administrative charges, falls on the business or employer.1JAMS. Arbitration Schedule of Fees and Costs AAA maintains similar policies under its consumer and employment rules, capping individual filing fees well below the standard commercial rates.
For comparison, filing a civil lawsuit in California Superior Court costs $435 for an unlimited case (claims over $35,000) and $225 to $370 for limited civil cases. The $250 to $400 range JAMS charges employees and consumers tracks what you would pay to file in court, which is the point of the Armendariz rule.
Fee Waivers for Low-Income Consumers
If you’re a consumer with a gross monthly income below 300% of the federal poverty guidelines, California law requires arbitration providers to waive all administrative fees and costs. The arbitrator’s own fee is not part of this waiver, but in consumer cases the business pays that anyway. The arbitration company must notify you of this right in its first written communication and in every invoice or fee schedule it sends.4California Legislative Information. California Code CCP – 1284.3
To qualify, you sign a declaration under oath stating your monthly income and household size. The provider cannot demand additional proof of financial hardship beyond that declaration, and any financial information you submit must be kept confidential from the opposing party.4California Legislative Information. California Code CCP – 1284.3
Loser-Pays Clauses Do Not Apply to Consumers
California Code of Civil Procedure Section 1284.3 prohibits any arbitration agreement from requiring a consumer to pay the other side’s fees and costs if the consumer loses. A “loser pays all” clause in a consumer arbitration agreement is unenforceable in California.4California Legislative Information. California Code CCP – 1284.3
The 30-Day Payment Ruleh2>
Under Code of Civil Procedure Sections 1281.97 and 1281.98, when an employer or business is responsible for paying arbitration fees, those fees must be paid within 30 days of the invoice date. Missing that deadline is treated as a material breach of the arbitration agreement, and the company waives its right to compel arbitration.5California Legislative Information. California Code CCP – 1281.97
Section 1281.97 covers fees required to start the arbitration; Section 1281.98 covers fees that come due later in the proceeding. The consequences are the same. If the drafting party doesn’t pay on time, the employee or consumer can withdraw from arbitration and take the case to court, or continue in arbitration and force the company to pay attorney’s fees on top of everything else.6California Legislative Information. California Code CCP – 1281.98
Businesses have argued that this rule conflicts with the Federal Arbitration Act. In 2025, the California Supreme Court rejected that argument in Hohenshelt v. Superior Court, holding that Section 1281.98 does not disfavor arbitration or interfere with its core features. The court did soften the edges: rather than a strict bright-line rule, equitable principles apply. A genuinely inadvertent late payment or good-faith effort to comply won’t necessarily trigger the statutory penalties, but willful or grossly negligent nonpayment will.7Justia. Hohenshelt v Superior Court
Business-to-Business Cost Allocation
When two businesses arbitrate a commercial dispute, none of the consumer and employee protections above apply. Fee allocation is governed entirely by the arbitration clause in the contract. The most common arrangement is a 50/50 split of all administrative and arbitrator fees, but parties can negotiate other terms, such as requiring the losing party to cover all costs or setting a different percentage.
Because arbitrator fees are billed hourly and commercial cases often involve extensive document review and multi-day hearings, total costs can escalate quickly. A single arbitrator handling a moderately complex case over two or three hearing days might generate $15,000 to $30,000 or more in professional fees alone. For a three-arbitrator panel, multiply that figure significantly.
Other Costs Beyond the Provider
Fees paid to JAMS, AAA, or the arbitrator are only part of the total expense. You’ll also face costs for the professionals and services needed to build and present your case:
- Attorney’s fees. Most parties hire a lawyer. Hourly rates for California civil attorneys vary widely with experience and firm size, but expect rates comparable to litigation counsel.
- Expert witnesses. Specialists who testify about technical, financial, or medical issues typically charge several hundred dollars per hour for both preparation and testimony.
- Discovery costs. Depositions, document production, and subpoenas generate charges for court reporters, copying, and sometimes e-discovery vendors.
- Hearing room rental. Some providers include hearing space in their fees; others charge separately, especially for multi-day proceedings.
Attorney’s fees are frequently the largest total expense in an arbitration, exceeding even the arbitrator’s professional fee, particularly in cases involving significant pre-hearing motion practice or lengthy discovery.
How the Final Award Handles Costs
The arbitrator’s final award resolves both the underlying dispute and, in most cases, who bears the costs. California Code of Civil Procedure Section 998 creates an incentive to settle early. If one side makes a written settlement offer that the other rejects, and the rejecting party then gets a worse result at the hearing, the arbitrator can shift post-offer costs to the party who refused the deal, including administrative fees and potentially expert witness costs.8California Legislative Information. California Code of Civil Procedure 998
Outside of Section 998, cost-shifting depends on what the arbitration agreement says. Many commercial contracts include a “prevailing party” clause that entitles the winner to recover filing fees, administrative charges, and sometimes attorney’s fees. Without such a clause, each side generally bears its own costs regardless of outcome.
