The outcome of most arbitration cases is decided long before the hearing begins. How you prepare for arbitration — gathering the right evidence, organizing your documents, and building a clear narrative — determines whether you walk into the hearing with confidence or scramble to explain gaps.
Arbitration offers limited discovery and compressed timelines, so your arbitration preparation must be more disciplined and self-directed than a courtroom process. This guide covers what to gather, how to organize it, and the mistakes that cost parties winnable disputes.
Strong arbitration cases rest on documentation, not dramatic testimony. Start your arbitration preparation by assembling these core categories of evidence.
The arbitration clause itself is your starting point. Pull every relevant contract, amendment, side letter, addendum, and statement of work. Arbitrators read contract language closely — often more closely than you did when you signed it. Flag the specific provisions at issue and note any ambiguities the other side might exploit.
Also gather related agreements: non-disclosure agreements, service-level agreements, partnership documents, or employment handbooks. These secondary documents often contain terms that shape the arbitrator’s interpretation.
Collect all emails, text messages, letters, and chat logs related to the dispute. Arbitrators increasingly treat informal messages — Slack threads, WhatsApp conversations, even voicemail transcripts — as admissible evidence.
Organize correspondence chronologically. A well-ordered communication trail tells a story more powerfully than any opening statement. Pay special attention to messages where the other party acknowledged obligations, admitted fault, or changed their position.
If your claim involves damages, you need hard numbers. Assemble invoices, payment records, bank statements, profit-and-loss statements, tax returns, and any financial projections you relied on. The arbitrator will want to see not just what you lost, but how you calculated it.
Under the AAA Commercial Arbitration Rules (Rule 23), arbitrators have broad discretion to consider relevant evidence — but your financial records must still be organized, labeled, and traceable.
In construction, property, and product liability disputes, visual evidence can be decisive. Document physical conditions with dated, high-resolution photographs. If video footage exists — security cameras, site inspections, or recorded meetings — preserve it immediately with its original metadata intact.
Complex cases often require expert analysis — a forensic accountant for financial disputes, an engineering report for construction cases, or a labor economist for employment claims. Retain your expert early, because arbitration timelines are tight and a rushed report undermines credibility.
Under the FAA (9 U.S.C. § 7), arbitrators have broad authority to determine what evidence to admit. A well-prepared expert report carries enormous weight because there are fewer procedural filters than in court — and once the award is issued, the grounds for appealing an arbitration decision are extremely narrow.
Having the right evidence is only half the battle. Presenting it clearly is the other half.
Create a master index listing every document by number, a short description, date, and the issue it supports. Arbitrators handle multiple cases and should never have to guess what a document proves or where it fits.
Most practitioners organize evidence two ways: a chronological binder showing the full timeline, and a thematic set grouped by issue — for example, “Formation of Agreement,” “Performance and Payments,” “Breach Events,” and “Damages.”
In disputes involving multiple individuals, create a one-page reference identifying each person, their role, and their connection to the issues. Arbitrators appreciate this kind of orientation document in complex commercial cases.
Witness testimony in arbitration is typically more relaxed than courtroom testimony, but less polished witnesses lose credibility fast.
Arbitrators are experienced professionals — many are retired judges or senior attorneys. They recognize when a witness has been coached to argue rather than testify. Prepare witnesses to state facts clearly, acknowledge what they do not know, and avoid volunteering opinions outside their direct knowledge.
Walk each witness through the documents they will be asked about. Can they identify them? Do they remember the context? A witness who fumbles when shown their own email loses the arbitrator’s trust.
The other side will challenge your witnesses. Prepare them for the most uncomfortable questions — the weakest points in your case, the places your side made mistakes. A witness who handles tough questions honestly is more persuasive than one who deflects.
One of the biggest arbitration preparation mistakes is assuming discovery works like litigation. It does not. Under the FAA (9 U.S.C. § 7), arbitrators can compel witnesses and document production, but pre-hearing depositions, interrogatories, and broad document requests are far more restricted than in federal court.
Gather your own evidence proactively. If you need documents from the opposing party, make targeted requests early. Broad fishing expeditions will be denied, and they signal that your case lacks focus.
Circuit courts are also split on whether arbitrators can issue pre-hearing subpoenas to non-parties. The Fourth Circuit permits it (COMSAT Corp. v. National Science Foundation, 190 F.3d 269 (4th Cir. 1999)), while the Third Circuit does not (Hay Group, Inc. v. E.B.S. Acquisition Corp., 360 F.3d 404 (3d Cir. 2004)). Check the law in your jurisdiction.
Arbitrators read pre-hearing briefs before testimony begins, and those briefs frame how they process everything that follows. A strong brief includes a concise statement of facts (with citations to your evidence), the legal issues, applicable standards, and the specific relief you seek. Shorter, well-organized briefs are consistently more persuasive.
While each case varies, this framework applies to most commercial disputes:
Experienced arbitrators see the same errors repeatedly:

At a minimum, gather the underlying contract and arbitration clause, all related correspondence (emails, messages, letters), financial records supporting your damages claim, photographs or physical evidence, and expert reports if the dispute involves technical issues. Organize everything chronologically and create a master evidence index.
Arbitration discovery is significantly more limited. Under the FAA (9 U.S.C. § 7), arbitrators can compel witnesses and document production, but pre-hearing depositions and broad interrogatories are uncommon. Most arbitration rules give the arbitrator discretion to restrict discovery to what is directly relevant. Gather your own evidence proactively rather than rely on obtaining it from the other side.
Start immediately after filing or receiving a claim. Issue document preservation notices right away and begin organizing your evidence. Most procedural orders require document exchanges 30 to 60 days before the hearing, with pre-hearing briefs due about two weeks before. Rushing preparation in the final days is one of the most common mistakes.
A strong pre-hearing brief includes a concise statement of facts with citations to specific evidence, a clear list of the legal issues in dispute, the applicable legal standards, and the specific relief you are seeking. Arbitrators consistently prefer shorter, well-organized briefs over lengthy submissions. The brief frames how the arbitrator processes all testimony, making it one of the most influential arbitration documents in the case.
Yes. Settlement negotiations can happen at any stage. In fact, thorough preparation often strengthens your negotiating position because the other side can see you are ready for the hearing. For guidance on settlement during an active arbitration, visit arbitration.net or dial (888) 885-5060.
