Arbitrator Accreditation · Get comfortable with the vocabulary.

Arbitration agreement

A contract in which parties agree to submit present or future disputes to arbitration instead of court litigation. It may be a standalone document or a clause inside a wider contract.

Related: Separability doctrine, Competence-competence, Seat of arbitration
Separability doctrine

The principle that an arbitration clause survives independently even if the surrounding contract is void, rescinded, or terminated. Arbitrators can therefore rule on the main contract without losing jurisdiction over the dispute.

Related: Arbitration agreement, Competence-competence
Competence-competence

The rule allowing a tribunal to decide whether it has jurisdiction over a dispute, including challenges to the validity of the arbitration agreement, subject to later court review at the seat or enforcement stage.

Related: Separability doctrine, Jurisdiction challenge
Seat of arbitration

The legal place of the arbitration, which determines the procedural law governing the proceedings and the courts that supervise the tribunal. It is distinct from the physical location of hearings.

Related: Lex arbitri, Delocalization
Lex arbitri

The national law governing the arbitration procedure itself, usually the law of the seat. It regulates matters such as tribunal constitution, interim measures, and grounds for setting aside awards.

Related: Seat of arbitration, Setting aside an award
New York Convention

A multilateral treaty under which states recognise and enforce foreign arbitral awards and honour written arbitration agreements. It supplies the main cross-border enforcement framework relied on in international practice.

Related: Enforcement of award, Public policy exception
Enforcement of award

The process of asking a competent court to give legal effect to an arbitral award, typically by recognition and entry of judgment. Successful enforcement allows the creditor to pursue execution against assets.

Related: New York Convention, Public policy exception
Setting aside an award

A challenge brought before a court at the seat asking it to annul an award, usually on limited grounds such as lack of jurisdiction, procedural unfairness, or serious irregularity. It differs from resisting enforcement abroad.

Related: Lex arbitri, Due process challenge
Public policy exception

A narrow ground on which a court may refuse to recognise or enforce an award because enforcement would violate fundamental notions of justice or morality in the forum state. It is interpreted restrictively.

Related: New York Convention, Enforcement of award
Delocalization

A theoretical approach treating international arbitration as detached from the law of the seat, so that annulment there has limited effect elsewhere. Most courts and statutes still give significant weight to the seat.

Related: Seat of arbitration, Setting aside an award
Arbitrability

The question whether a particular subject matter may lawfully be resolved by arbitration under applicable law. Certain disputes, such as some criminal, family, or regulatory matters, are reserved to courts.

Related: Arbitration agreement, Public policy exception
Institutional arbitration

Arbitration administered by a permanent body that maintains rules, manages communications, and scrutinises awards. The institution does not decide the dispute; the tribunal does.

An objection that the proceedings denied a party an adequate opportunity to present its case or respond, often raised against an award. Courts scrutinise such claims closely but apply a high threshold.
