Arbitration Glossary: Key Terms and Definitions

Arbitration carries a distinct vocabulary that shapes how disputes are initiated, conducted, and resolved outside of court. This glossary defines the foundational terms used across arbitration agreements, procedural rules, and federal and state statutes. Precise terminology matters because misreading a clause or award standard can affect enforceability, appeal rights, and cost allocation. The definitions below draw on the Federal Arbitration Act (9 U.S.C. §§ 1–16), the American Arbitration Association (AAA), JAMS, and the Revised Uniform Arbitration Act (RUAA).

Definition and scope

Arbitration terminology spans three overlapping domains: agreement formation, procedural mechanics, and award enforcement. Each domain has terms with specific legal meanings that differ from their colloquial use.

Arbitration — A private, adjudicative dispute resolution process in which one or more neutral decision-makers (arbitrators) hear evidence and render a binding or non-binding decision. Distinguished from mediation, where a neutral facilitates settlement without deciding the outcome.

Arbitration Agreement — A contract provision or standalone document in which parties consent to resolve disputes through arbitration rather than litigation. Governed at the federal level by the Federal Arbitration Act (FAA), which mandates enforcement of valid arbitration agreements in contracts involving interstate commerce (9 U.S.C. § 2).

Arbitration Clause — The specific contractual language embedding an arbitration agreement within a broader contract. The scope, seat, and governing rules of an arbitration clause determine which disputes are covered and how they proceed. Poorly drafted clauses are a primary source of arbitrability disputes.

Arbitrability — The threshold question of whether a particular dispute is subject to arbitration at all. Divided into two sub-types: substantive arbitrability (whether the dispute falls within the clause's scope) and procedural arbitrability (whether conditions precedent to arbitration, such as notice requirements, have been met). The U.S. Supreme Court addressed the delegation of arbitrability determinations in First Options of Chicago, Inc. v. Kaplan, 514 U.S. 938 (1995).

Seat of Arbitration — The legal jurisdiction governing the arbitration proceeding, distinct from the physical location where hearings occur. The seat determines which national courts exercise supervisory jurisdiction over the arbitration and which procedural law applies.

Governing Rules — The procedural framework adopted by parties, such as the AAA Commercial Arbitration Rules or JAMS Comprehensive Arbitration Rules, which specify timelines, discovery parameters, arbitrator selection procedures, and fee structures.

Mandatory Arbitration Clause — A clause, typically in a standard-form contract, requiring arbitration of disputes as a non-negotiable condition. Subject to regulatory scrutiny in consumer and employment contexts. The Ending Forced Arbitration of Sexual Assault and Sexual Harassment Act of 2021 (Pub. L. 117-90), enacted March 3, 2022, amends the FAA to invalidate pre-dispute arbitration agreements and pre-dispute joint-action waivers to the extent they apply to cases arising under Federal, Tribal, or State law and relating to sexual assault disputes or sexual harassment disputes. The Act applies to any dispute or claim that arises or accrues on or after March 3, 2022, regardless of when the underlying arbitration agreement was entered into. The person alleging sexual assault or sexual harassment retains the unilateral right to elect to void any such pre-dispute agreement and pursue the claim in court. Critically, determinations of the Act's applicability are expressly reserved for a court, not an arbitrator, even where the underlying agreement contains a delegation clause purporting to assign arbitrability questions to an arbitrator.

How it works

Understanding arbitration terminology requires mapping terms to the 5 major phases of the process:

  1. Pre-dispute agreement — Parties adopt an arbitration clause (in a contract) or a submission agreement (after a dispute arises).
  2. Initiation — The claimant files a demand for arbitration, a formal document asserting claims and requesting relief.
  3. Arbitrator selection — Parties select a sole arbitrator or an arbitration panel (typically 3 arbitrators) through a ranking or strike process administered by the arbitral institution.
  4. Hearing and discovery — Evidence is exchanged under rules that are typically narrower than Federal Rules of Civil Procedure. The hearing involves witness testimony, documentary evidence, and argument.
  5. Award and enforcement — The arbitrator issues an award, which courts confirm, vacate, or modify under FAA §§ 9–11.

Award — The arbitrator's final written decision resolving the dispute. An award may be interim (addressing procedural or preliminary matters) or final (resolving all claims). An award is binding when parties have contractually agreed to treat it as final. Non-binding awards are advisory only. See the distinction at binding vs. nonbinding arbitration.

Claimant / Respondent — The party initiating arbitration (claimant) and the party against whom claims are brought (respondent). Equivalent to plaintiff and defendant in litigation but without the court's procedural formality.

Default Award — An award entered against a party who fails to participate after proper notice. AAA Rule R-31 governs defaults under the Commercial Arbitration Rules.

Interim Measures — Provisional orders issued by an arbitrator prior to a final award, such as orders preserving assets or maintaining the status quo. Availability depends on the governing rules and the seat's national law.

Fee Shifting — Allocation of arbitration costs and attorney fees between parties. Arbitrators may shift fees as a remedy or under contractual fee-shifting clauses. Consumer-facing fee structures are subject to AAA Consumer Due Process Protocol standards.

Common scenarios

Arbitration terminology applies differently across practice areas. The following terms appear with particular frequency in 4 recurring contexts:

Commercial arbitration: Force majeure, consequential damages waiver, and liquidated damages are substantive contract terms that arbitrators interpret when adjudicating commercial disputes under commercial arbitration frameworks.

Securities arbitration: FINRA Rule 12100 defines associated person, customer, and industry party — classifications that determine which FINRA arbitration forum tracks apply to a given dispute.

Labor arbitration: A grievance is a formal complaint under a collective bargaining agreement (CBA); the grievance arbitration process resolves whether the employer violated the CBA. The National Labor Relations Act (29 U.S.C. § 151 et seq.) frames the statutory backdrop.

International arbitration: Lex arbitri refers to the procedural law of the seat; lex causae refers to the substantive law governing the merits. The New York Convention (Convention on the Recognition and Enforcement of Foreign Arbitral Awards, 1958) governs enforcement of foreign awards in 172 signatory states as of the Convention's public record.

Decision boundaries

Certain terms define the outer limits of arbitration's authority and the conditions under which courts intervene.

Vacatur — Judicial invalidation of an arbitration award. Under 9 U.S.C. § 10, grounds for vacatur are narrow: corruption, fraud, evident partiality, arbitrator misconduct, or exceeding powers. Courts do not review arbitration awards for legal error under the FAA's default standard.

Manifest Disregard of the Law — A judicially created (non-statutory) ground for vacatur, applied inconsistently across federal circuits. The U.S. Supreme Court in Hall Street Associates, LLC v. Mattel, Inc., 552 U.S. 576 (2008), held that FAA §§ 10–11 provide the exclusive statutory grounds for vacatur, casting doubt on extra-statutory standards.

Unconscionability — A contract defense that may defeat enforcement of an arbitration clause if the clause is procedurally unconscionable (oppressive bargaining process) or substantively unconscionable (one-sided terms). State contract law governs unconscionability analysis, preserved by FAA § 2's savings clause.

Class Action Waiver — A provision prohibiting parties from pursuing arbitration on a class or collective basis. Enforced by the FAA in most commercial and consumer contexts following AT&T Mobility LLC v. Concepcion, 563 U.S. 333 (2011). See class action arbitration waivers for the full doctrinal scope.

Evident Partiality — A statutory vacatur ground under FAA § 10(a)(2), triggered when an arbitrator fails to disclose relationships or interests that create a reasonable impression of bias. The RUAA § 12 and AAA neutrality standards define disclosure obligations in greater procedural detail.

Confirmation — The judicial act of converting an arbitration award into a court judgment, making it enforceable through normal judgment-collection mechanisms. Filed in federal or state court under FAA § 9 or state equivalents within the applicable statute of limitations.
