Arbitration is often pitched as the faster, cheaper alternative to litigation. And in many cases, that is true. But if you go into the process expecting only a filing fee and an arbitrator's hourly rate, you may be caught off guard. Arbitration hidden fees can add thousands of dollars to your final bill, and most parties do not see them coming until they arrive.
This guide breaks down the unexpected arbitration costs that rarely appear in brochures or fee schedules. Whether you are a business owner, an employee, or a consumer entering dispute resolution for the first time, knowing where these charges hide puts you in a stronger position from day one.
When people research how much arbitration costs, they typically focus on two line items: the filing fee and the arbitrator's compensation. Those are real expenses, but they represent only a fraction of what you will actually spend.
Research from the International Chamber of Commerce (ICC) shows that the parties' own costs — attorney fees, expert witnesses, and evidence preparation — make up roughly 83% to 90% of total arbitration expenses. The arbitrator's fees and institutional administrative charges? They account for just 10% to 15%.
That gap is where the hidden costs live.
One of the most common unexpected arbitration costs is the postponement fee. Life happens: witnesses get sick, attorneys have scheduling conflicts, or new evidence surfaces at the last minute. When a hearing is delayed, someone pays for it.
Under FINRA arbitration rules, for example, a late cancellation request made within 10 days of a scheduled hearing session triggers a fee of $600 per arbitrator. With a three-member panel, that is $1,800 for a single postponement. Under AAA consumer arbitration rules, canceling an evidentiary hearing fewer than two business days before the scheduled date can result in charges for a full day of hearing time — typically eight hours at the arbitrator's daily rate.
These fees are not always spelled out in the initial cost estimate you receive when filing. Always ask about the cancellation and postponement policy before your first hearing is scheduled.
In disputes involving technical, financial, or scientific questions, expert witnesses are often necessary. But they are also expensive. According to the Expert Institute, expert witness fees in 2024 ranged from $250 to over $1,500 per hour, depending on the specialty and the complexity of the matter.
Unlike court proceedings, where the judge manages the pace and scope of expert involvement, arbitration gives parties wide latitude to present expert testimony. That flexibility comes with a price. You may need an expert to prepare a written report, sit for a deposition, and then testify during the hearing — each billed separately.
If you are weighing arbitration versus court costs, factor in the full scope of expert engagement. In a straightforward breach-of-contract case, you might not need an expert at all. In a construction defect or intellectual property matter, expert fees can rival the cost of everything else combined.
Arbitration proceedings are not automatically recorded or transcribed. If you want a written record of the hearing — and there are strong reasons to have one, especially if you anticipate a challenge to the award — you will need to hire a court reporter or transcription service yourself.
Hearing transcripts typically run $3 to $8 per page. A single day of testimony can produce 200 to 400 pages. Over a multi-day hearing, transcript costs alone can reach $5,000 to $10,000 or more.
This is an expense that many first-time parties discover only after the process begins. If a transcript is important to your case, budget for it up front and discuss cost-sharing with the opposing party early in the proceedings.
Every major arbitration institution charges administrative fees beyond the initial filing cost. These fees cover case management, document processing, scheduling, and communications between the parties. They are typically calculated based on the amount in dispute.
For example, a commercial claim with $500,000 at stake may trigger administrative fees of $5,000 to $10,000 or more, depending on the institution. Some providers also charge separate fees for preliminary conferences, discovery motions, and interim rulings — each adding to the total.
Digital platforms like Arbitration.net are designed to reduce this overhead. By handling scheduling, document exchange, and communications through a single online platform, many of the administrative line items that inflate costs at traditional institutions are reduced or removed entirely.

Choosing between a sole arbitrator and a three-member panel is one of the biggest cost decisions you will make. A three-arbitrator panel does not just triple the arbitrator fees — it also multiplies scheduling complexity, deliberation time, and the length of the hearing itself.
For disputes under $250,000, a sole arbitrator is often the most sensible choice. The proceedings move faster, scheduling is simpler, and the cost savings can be significant. In larger, more complex cases where the stakes justify multiple perspectives, a panel may be appropriate — but go in with eyes open about the expense.

In-person arbitration hearings require a physical location, and that location costs money. Hearing room rentals, travel for attorneys and witnesses, hotel stays, and meals all add up quickly — especially when the arbitration seat is in a different city or state from one or both parties.
These logistical costs are often overlooked during the planning phase. They can easily reach $2,000 to $5,000 per hearing day, depending on the location and the number of people involved.
Online arbitration eliminates most of these expenses entirely. Conducting hearings by video conference removes the need for travel, lodging, and venue rental — one of the reasons fully digital dispute resolution platforms have gained ground since 2020.
Discovery in arbitration is typically narrower than in litigation, but it is not free. Document production, written interrogatories, and pre-hearing depositions all generate costs. If the opposing party resists disclosure, you may need to file a discovery motion — which itself may carry a fee at certain institutions.
The U.S. Supreme Court addressed the cost barrier in Green Tree Financial Corp.-Alabama v. Randolph, 531 U.S. 79 (2000), holding that prohibitively high arbitration costs could prevent a party from effectively pursuing their claims. The Court placed the burden of proving such costs on the party challenging the arbitration agreement, but the ruling confirmed an important principle: cost is a legitimate concern in arbitration.
More recently, in Frazier v. X Corp. (2d Cir. 2025), the Second Circuit held that federal courts lack the authority to compel a party to pay arbitration fees during an ongoing proceeding. The case reinforced that fee allocation disputes are matters for the arbitrator or the administering body to resolve — not the courts.
The arbitration does not end when the arbitrator issues a decision. If the losing party does not voluntarily comply with the award, the prevailing party must go to court to confirm and enforce it under the Federal Arbitration Act (9 U.S.C. sections 9-13). That means filing fees, attorney time, and potentially months of additional proceedings.
And if the losing party challenges the award — seeking vacatur under 9 U.S.C. section 10 — both sides face a new round of legal expenses. While the grounds for vacating an arbitration award are narrow, defending against a challenge still costs money.
These post-award expenses are almost never included in initial cost projections. Understanding them ahead of time helps you build a realistic budget for the full lifecycle of a dispute.

The most common arbitration hidden fees include postponement and cancellation charges, expert witness expenses, hearing transcript costs, administrative and institutional overhead beyond the filing fee, and travel and venue costs for in-person proceedings. Post-award enforcement expenses are also frequently overlooked. Requesting an itemized fee schedule from the administering institution before proceedings begin is the best way to avoid surprises.
The amount varies by case, but party expenses — including attorney fees, experts, and evidence preparation — account for 83% to 90% of total arbitration costs according to ICC data. A case that initially appears to cost $10,000 in arbitrator and administrative fees may actually total $50,000 or more when expert witnesses, transcripts, discovery, and post-award proceedings are factored in.
It depends on the arbitration agreement, the applicable rules, and the arbitrator's discretion. Many institutional rules allow the arbitrator to allocate costs, including attorney fees and arbitration expenses, as part of the final award. Some contracts specify that the losing party pays all costs, while others split them. Review your agreement carefully and discuss fee allocation with your attorney early in the process.
Choose a sole arbitrator instead of a three-member panel when possible. Conduct hearings online to remove travel and venue costs. Negotiate narrow discovery terms before hearings begin. Decide early whether you need a transcript and share the cost with the opposing party. Use a digital platform like Arbitration.net that bundles administrative functions into a streamlined process, reducing the line items that pile up at traditional institutions.
