An arbitrator is a private decision-maker, usually an experienced attorney or retired judge, who resolves a dispute outside of court by hearing evidence, applying the law, and issuing a ruling that is typically final. If you are asking what an arbitrator is, the short version is this: an arbitrator functions as a privately hired judge whose decision binds the parties in the same way a court judgment would.
What an Arbitrator Does
An arbitrator runs the case from start to finish. They set deadlines, decide what evidence comes in, and ultimately rule on who wins and what they get. The hearing looks like a trial, but with fewer formalities: there is no jury, the rules of evidence are relaxed, and the process usually wraps up faster than litigation would.
Along the way, the arbitrator handles every procedural question that comes up. They decide whether depositions are allowed, how many documents each side can request, how long each party gets to present its case, and whether the arbitration clause even covers the dispute in the first place. Those procedural rulings are difficult to overturn later, which gives the arbitrator enormous control over how the case unfolds.
Arbitrators also commonly accept evidence a court would exclude, including hearsay testimony. Evidentiary rulings by an arbitrator are extremely difficult to challenge afterward. The trade-off is efficiency: hearings move faster when the arbitrator does not need to rule on every objection the way a trial judge would.
Arbitrator vs. Mediator
People confuse these roles constantly, and the difference matters. A mediator helps the parties talk through a dispute and reach a voluntary agreement; the mediator has no power to impose a result, and if the parties cannot agree, nothing happens. An arbitrator decides the outcome, and in most cases that decision is binding. You do not get to walk away and try again in court.
How You End Up in Front of One
Most people encounter arbitration not because they chose it, but because a clause buried in a contract requires it. Employment agreements, cell phone contracts, credit card terms, nursing home admission forms, and software licenses routinely include mandatory arbitration provisions. If you signed one, you agreed to resolve disputes through arbitration instead of filing a lawsuit.
The Federal Arbitration Act makes these clauses enforceable. Under 9 U.S.C. § 2, a written agreement to arbitrate any dispute arising from a contract involving commerce is “valid, irrevocable, and enforceable,” with only narrow exceptions for general contract defenses like fraud or duress.1Office of the Law Revision Counsel. 9 U.S. Code 2 – Validity, Irrevocability, and Enforcement of Agreements to Arbitrate If you file a lawsuit on an issue covered by an arbitration agreement, the other side can ask the court to halt the case and send you to arbitration instead.2Office of the Law Revision Counsel. 9 U.S. Code 3 – Stay of Proceedings Where Issue Therein Referable to Arbitration
Who Serves as an Arbitrator and How They Are Chosen
The parties usually pick their own arbitrator, either by agreeing on someone directly or by choosing from lists provided by organizations like the American Arbitration Association (AAA) or JAMS. When neither side can agree, the administering organization appoints one. For larger disputes, the parties sometimes select a three-arbitrator panel, with each side picking one and those two selecting the third.
Most arbitrators are experienced attorneys or retired judges, but subject-matter expertise often matters as much as legal credentials. The AAA maintains specialized panels with real qualification thresholds. Attorneys on the construction panel need at least 10 years of legal practice with at least half their work devoted to construction law. Technology panel attorneys need a minimum of 10 years with at least 30 percent of their practice focused on technology-related disputes.3American Arbitration Association. Qualification Criteria for Members of the AAA Roster of Arbitrators Industry professionals without law degrees can also serve. Construction professionals, for example, qualify with 10 years of progressive project experience.
This specialization is one of arbitration’s genuine advantages over court. A federal judge assigned a patent dispute might never have handled one before. An arbitrator chosen from a technology panel lives in that world.
Impartiality and Disclosure
Impartiality is the foundation of the system. Arbitrators on the AAA panel are bound by the AAA-ABA Code of Ethics for Arbitrators in Commercial Disputes, which requires them to disclose any relationship, financial interest, or prior dealing that could create even an appearance of bias.4American Arbitration Association. Panel Ethics and Guidelines JAMS has its own ethics guidelines with similar requirements.
In practice, disclosure works like this. Before accepting a case, the arbitrator receives the names of the parties, their attorneys, and any related entities, then searches their records and memory for connections. Former law firm colleagues, past business dealings, financial interests in a party’s company, prior service as an arbitrator for one of the parties: all of it must be disclosed. The parties can then decide whether to accept the arbitrator or request a different one. Failure to disclose a material conflict is one of the few grounds for overturning an award later.
Is the Arbitrator’s Decision Final?
The arbitration agreement determines whether the arbitrator’s decision is the final word or just a recommendation. In binding arbitration, the ruling (called an “award”) carries the same legal weight as a court judgment. You cannot reject it and start over in court. The overwhelming majority of arbitration clauses in employment and consumer contracts call for binding arbitration.
Non-binding arbitration is rarer. The arbitrator still hears the case and issues an award, but either party can reject it and proceed to litigation. Some courts order non-binding arbitration as a way to encourage settlement before trial.
Types of Awards
An arbitrator can issue different kinds of awards depending on the rules or the parties’ agreement. A standard award simply states who won and the dollar amount, with no explanation. A reasoned award goes further, explaining in the arbitrator’s own words the factual and legal disagreements and how the arbitrator resolved them.5Judicature. But Is It Reasoned? If you want to understand why you won or lost, request a reasoned award up front. It costs more because of the additional drafting time, but it is the only way to get a written explanation of the arbitrator’s reasoning.
Confirming and Challenging an Award
A binding award does not enforce itself. To turn it into something you can collect on, you go to court and ask a judge to “confirm” it, converting it into a court judgment. Under 9 U.S.C. § 9, any party can file a motion to confirm within one year after the award is issued, and the court must confirm it unless one of the narrow grounds for overturning it applies.6Office of the Law Revision Counsel. 9 U.S. Code 9 – Award of Arbitrators; Confirmation; Jurisdiction; Procedure
Those grounds are intentionally limited. Under 9 U.S.C. § 10, a court can vacate an award only for:
- Corruption or fraud in obtaining the award.
- Evident partiality or a conflict of interest on the arbitrator’s part.
- Misconduct, such as refusing to postpone a hearing despite good cause, refusing to hear relevant evidence, or other behavior that prejudiced a party’s rights.
- Exceeding authority, meaning the arbitrator ruled on issues outside the scope of the arbitration agreement or failed to issue a final, definite award.
That is the complete list.7Office of the Law Revision Counsel. 9 U.S. Code 10 – Same; Vacation; Grounds; Rehearing You cannot vacate an award just because the arbitrator got the law wrong or weighed the evidence poorly. Courts have consistently held that legal error alone is not enough. This is where arbitration diverges most sharply from litigation: there is no meaningful appeal on the merits. Courts can also modify an award for technical problems like a miscalculation of figures or a mistake in a name or description.8Office of the Law Revision Counsel. 9 U.S. Code 11 – Same; Modification or Correction; Grounds; Order
What It Costs to Have One Decide Your Case
Arbitration is not free, and the costs can surprise people who assume it is a cheap alternative to court. There are three categories: filing and administrative fees paid to the arbitration organization, the arbitrator’s professional fees, and your own attorney’s fees.
The AAA charges filing fees based on the dollar amount of the claim. For a dispute under $75,000, the initial filing fee is $1,450, with an additional final fee of $1,150 once the case proceeds to hearing. For claims between $1 million and $10 million, the initial fee jumps to $8,925 and the final fee to $9,675. Claims above $10 million carry a $13,500 initial fee plus a percentage of the amount above $10 million. JAMS charges a flat $2,000 filing fee for two-party matters and $3,500 when three or more parties are involved.9JAMS. Arbitration Schedule of Fees and Costs
Arbitrators charge by the hour or the day for hearing time, and separately for time spent reviewing briefs and writing the award. Hourly rates generally range from a few hundred dollars to over $1,000 per hour, with retired judges and arbitrators in major markets like New York and Los Angeles commanding the highest fees. Some JAMS neutrals charge $15,000 or more per day. The parties typically split the arbitrator’s fees equally unless the agreement or applicable rules say otherwise.
You have the right to hire an attorney to represent you, and major arbitration organizations guarantee this in their rules. Whether you need one depends on the stakes and complexity, but for employment termination claims, business disputes, or anything involving significant money, showing up without a lawyer when the other side has one is a serious disadvantage.
Consumer and Employment Fee Protections
Recognizing that these costs could effectively block individuals from bringing claims, the major arbitration organizations have special fee rules for consumers and employees. Under JAMS consumer standards, a consumer initiating arbitration pays only $250, roughly equivalent to a court filing fee. The company pays everything else, including the arbitrator’s professional fees and all administrative costs.10JAMS. Consumer Arbitration Minimum Standards For employment disputes at JAMS, the employee pays only $400 to file.9JAMS. Arbitration Schedule of Fees and Costs The AAA has similar protections under its consumer and employment rules. If you are an individual facing arbitration against a company, check the applicable rules carefully. You likely owe far less than the standard fee schedule suggests.
