Most arbitrations take about seven to twelve months from the initial filing to a final written decision. Simple disputes handled under expedited rules can wrap up in two to three months, while complex commercial cases with multiple parties, heavy discovery, or a three-arbitrator panel can run well past a year. How long arbitration takes in any specific case depends on the complexity of the dispute, the rules of the administering organization, how cooperative the parties are, and whether the contract requires mediation or negotiation before arbitration can begin.
Even at the longer end, arbitration is generally faster than court litigation, which commonly takes two years or more to reach trial.
The Stages and How Long Each One Takes
Arbitration moves through a predictable sequence. Knowing where the time actually goes helps you see which stages you can influence and which are mostly out of your hands.
Filing and the Opposing Party’s Response
The clock starts when one party files a Demand for Arbitration with an administering organization such as the American Arbitration Association (AAA) or JAMS. The organization notifies the other side, who has 14 calendar days to file an answering statement under AAA’s Commercial Arbitration Rules.1American Arbitration Association. Commercial Arbitration Rules and Mediation Procedures If the responding party ignores the filing, nothing pauses. The arbitration proceeds, and the claims are treated as denied.
Selecting the Arbitrator
The organization sends the parties a list of qualified candidates. Most cases use a single arbitrator; complex commercial matters may call for a three-person panel. The parties either agree on a name or narrow the list through a ranking-and-striking process. Under AAA’s expedited roadmap, this stage typically falls between days 20 and 35 after filing.2American Arbitration Association (AAA). AAA Expedited/Fast Track Roadmap Standard commercial cases with busy arbitrators, or multi-party cases that require coordinating three schedules, can stretch selection to six weeks or longer.
Preliminary Hearing and Discovery
Once the arbitrator is appointed, a preliminary hearing is held, usually by phone or video. That conference sets the roadmap: deadlines for exchanging documents, identifying witnesses, and scheduling the merits hearing. AAA’s rules call for this conference to be scheduled as soon as practicable after appointment.1American Arbitration Association. Commercial Arbitration Rules and Mediation Procedures
Discovery is usually the longest single phase. It is more limited in arbitration than in court, but for commercial cases with substantial document volume or depositions, it commonly runs two to four months. This is also where delay most often creeps in, because every fight over what has to be produced can push the merits hearing back.
The Hearing and the Written Award
The hearing itself is where each side presents evidence and argument. A straightforward contract dispute might need only a day. A large commercial case with multiple claims and expert witnesses can run across several scheduled hearing days over several weeks.
After the hearing closes, the arbitrator has 30 calendar days under AAA’s standard commercial rules to issue the written decision, called an award. Under expedited rules, that window shrinks to 14 days.1American Arbitration Association. Commercial Arbitration Rules and Mediation Procedures
Expedited Arbitration for Smaller Claims
Most arbitration organizations offer a faster track for less complex disputes. Under AAA’s rules, the expedited procedures apply automatically when the monetary claim is $100,000 or less.3American Bar Association. Updates to the American Arbitration Association Commercial Arbitration Rules The whole process is designed to resolve within a few months.
Discovery is generally limited to document exchanges, and depositions happen only if the arbitrator finds good cause. The merits hearing must be scheduled no more than 60 days after the preliminary conference and is generally capped at one day, with the arbitrator allowed to add one more day for good cause.1American Arbitration Association. Commercial Arbitration Rules and Mediation Procedures For smaller claims, the arbitrator can decide the case entirely on written submissions, with no hearing at all. The award is due within 14 calendar days of the hearing’s close.
Extensions are also harder to obtain. Neither the AAA nor the arbitrator can grant more than one seven-day extension for responding to a demand or counterclaim, absent extraordinary circumstances.1American Arbitration Association. Commercial Arbitration Rules and Mediation Procedures
Consumer Arbitration Runs on a Faster Clock
If you were forced into arbitration by a clause in a service agreement or product contract, the timeline looks quite different from a commercial case. Under the AAA’s Consumer Arbitration Rules, disputes below $25,000 are resolved through document submission only, with no live hearing, unless a party requests one or the arbitrator decides one is needed.4American Arbitration Association. Consumer Arbitration Rules When a hearing is held, it is generally limited to one day; if a second day is needed, it must be scheduled within seven calendar days of the first. The arbitrator issues the award within 14 calendar days of closing the hearing. A consumer case often concludes in two to four months.
What Actually Stretches the Timeline
Complexity and Number of Parties
A two-party contract dispute with clear damages is a fundamentally different animal from a multi-party commercial case with counterclaims, cross-claims, and experts. Cases with three or more parties routinely take 50 to 100 percent longer than two-party disputes because of the logistical burden alone.
Discovery Volume and Cooperation
A case with a few hundred relevant documents can wrap discovery in a month. A case involving years of business records, electronic communications, or technical data can push discovery past four months. Voluntary, on-schedule exchanges keep the case moving. When one side fights every production request, the arbitrator has to intervene, hearings get postponed, and months slip away.
The Mandatory Mediation Step
Under AAA’s commercial rules, any case with a claim or counterclaim exceeding $100,000 automatically triggers a requirement to mediate concurrently with the arbitration.1American Arbitration Association. Commercial Arbitration Rules and Mediation Procedures Either party can opt out unilaterally by notifying the AAA and the other side, and the mediation is not supposed to delay the arbitration. In practice, coordinating a mediation session alongside the arbitration adds at least a few weeks. If mediation succeeds, the whole dispute can end far earlier than it otherwise would have.
Many commercial contracts also require the parties to negotiate or mediate before arbitration can even be filed. These pre-arbitration steps can add 30 to 90 days before the arbitration clock starts.
Arbitrator Availability
An in-demand arbitrator with a packed calendar can push the preliminary conference and the final hearing out by weeks. Three-arbitrator panels compound the problem, because all three calendars have to line up. Choosing a less prominent arbitrator can shorten the timeline, though parties often prefer experience over speed.
What Happens if the Other Side Refuses to Participate
A common worry is that an uncooperative opponent can stall indefinitely by refusing to show up. That is not how it works. Under the rules of the major arbitration organizations, the proceedings continue if one side refuses to participate. The arbitrator can hold hearings, receive evidence, and issue a binding award on whatever has been submitted. Under AAA’s commercial rules, failing to file an answering statement does not delay the arbitration at all.1American Arbitration Association. Commercial Arbitration Rules and Mediation Procedures A default award is not automatic, though. The arbitrator still weighs whether the evidence supports the claims.
After the Award: The Timeline Isn’t Always Over
Receiving the arbitrator’s decision does not always end things. Two post-award tracks can extend the process.
Confirming the Award
An arbitration award does not automatically carry the force of a court judgment. To enforce it, the winning party files a motion in court to confirm the award. Under the Federal Arbitration Act, you have up to one year after the award is issued to file that motion.5Office of the Law Revision Counsel. 9 USC 9 – Award of Arbitrators; Confirmation; Jurisdiction; Procedure Once confirmed, the award becomes a judgment enforceable like any other court order.
Challenging the Award
The losing party has a much tighter window. A motion to vacate must be served on the other party within three months of the award being delivered.6Office of the Law Revision Counsel. 9 USC 12 – Notice of Motions to Vacate or Modify; Service; Stay of Proceedings Courts can only vacate on narrow grounds: fraud or corruption in procuring the award, evident partiality by the arbitrator, misconduct that prejudiced a party’s rights, or the arbitrator exceeding the scope of their authority.7Office of the Law Revision Counsel. 9 USC 10 – Same; Vacation; Grounds; Rehearing Disagreeing with the arbitrator’s reasoning is not enough.
Practically, that means the total time from filing to a fully enforceable judgment can run several months longer than the arbitration itself. If you expect a fight over confirmation or vacatur, build another three to six months into your planning.
