Choosing the Right Arbitrator: Tips for Businesses and Individuals

Introduction

Selecting the right arbitrator matters. The arbitrator shapes the process, controls evidence and decides the outcome. A well chosen arbitrator brings technical knowledge, procedural firmness and credibility. A poor choice can add cost, slow the case or produce an outcome that misunderstands industry practice. This guide helps businesses and individuals in England and Wales choose an arbitrator who fits the dispute, the parties’ priorities and the chosen seat and rules.

Why arbitrator choice is critical

Expertise speeds resolution

An arbitrator with relevant subject matter knowledge understands technical documents and industry practice quickly. That reduces hearing time, limits the need for multiple experts and narrows issues. Parties expect a faster, more focused process when the tribunal has the right expertise.

Procedural style affects cost and timing

Arbitrators differ in case management approach. Some push strict timetables, limit disclosure and encourage early narrowing of issues. Others take a more investigative style that can increase cost and lengthen proceedings. Parties should choose an arbitrator whose procedural approach fits their budget and timetable.

Reputation and enforceability

Tribunals with respected arbitrators gain greater weight in enforcement and settlement talks. Opponents may accept adverse findings more readily if the arbitrator has a strong reputation. Reputation also affects the arbitrator’s perceived impartiality and the likelihood that courts will support interim measures.

Neutrality and party confidence

Parties need confidence in the arbitrator’s independence. Perceived or real conflicts of interest undermine the process and invite challenges or delays. Careful vetting and clear disclosures reduce the risk of later jurisdictional fights or setting aside applications.

Key criteria when choosing an arbitrator

Subject matter expertise

Assess the technical knowledge the dispute requires. Construction, engineering, shipping, energy and financial disputes often need arbitrators with sector specific experience. An arbitrator who has worked in the relevant industry or who has decided similar disputes will usually add real value.

Legal experience and procedural skill

Some disputes turn on complex points of law rather than technical facts. For those cases appoint an arbitrator with strong substantive legal experience, such as a practising barrister or a former judge who understands complex legal argument and precedent. Procedural skill matters too: an arbitrator should manage hearings, evidence and cost issues effectively.

Language and cultural competence

If the dispute involves parties from different jurisdictions, select an arbitrator fluent in the chosen language and sensitive to cross cultural issues. Language ability reduces translation needs and avoids misunderstandings in witness evidence and oral submissions.

Availability and timetable

An arbitrator’s diary affects how quickly a case proceeds. Confirm availability for the anticipated hearing window and for any need to sit for multiple short sessions. An arbitrator with heavy commitments may delay progress or require breaks that increase cost.

Cost and fee structure

Arbitrator fees can form a substantial part of tribunal costs. Parties should obtain clear fee estimates, including hourly or daily rates, anticipated hearing days and fees for preparation and reading time. Consider whether the arbitrator will accept a cap, staged payments or a blended fee arrangement.

Impartiality and conflict checks

Request full disclosure of any prior or current relationships with the parties, counsel or related companies. Check for past appointments that might create perceived bias. Good arbitrators provide prompt, thorough conflict checks and accept reasonable limitations or recusal where appropriate.

Gender, diversity and independence

Diversity enhances tribunal quality and reflects modern commercial values. Consider gender and other diversity criteria when appointing arbitrators. Some institutions and clients now require reasons for any lack of diversity in tribunal composition.

Single arbitrator or three person tribunal

Single arbitrator: speed and cost

A single arbitrator usually suits lower value or less complex disputes where speed and cost control matter. Single arbitrators reduce appointment time and tribunal fees and often provide a quicker route to a final award.

Three person panel: balance and experience

A three arbitrator panel suits high value or legally and factually complex disputes. A three person tribunal brings multiple perspectives and reduces the risk that a single arbitrator will make a serious error. Panels increase cost and can complicate case management but they often produce more balanced outcomes in significant disputes.

How tribunals are appointed

Contract clause controls appointment

Many disputes follow the contract’s arbitration clause. The clause should specify the appointment mechanism such as party nomination, institutional appointment or a named appointing authority. Clear drafting reduces argument about constitution later.

Institutional appointment

Arbitral institutions provide appointment procedures and replacement mechanisms where parties fail to agree. Using an institution like the LCIA, ICC or SIAC reduces friction and often speeds constitution, particularly in cross border disputes.

Ad hoc appointments and the court

Ad hoc arbitration gives flexibility but requires careful appointment wording. Where parties cannot agree, the courts at the seat can appoint arbitrators under local law. In England and Wales the Arbitration Act 1996 allows court intervention to appoint arbitrators when needed.

Practical steps to vet and select an arbitrator

Start early and define needs

Begin the selection process at the earliest contracting or dispute stage. Identify whether the dispute needs technical expertise, strict procedural management or strong legal reasoning. A clear brief saves time during the appointment phase.

Prepare a short list

Compile a list of suitable candidates with relevant expertise, availability and fee expectations. Use institutional panels, counsel recommendations and professional directories to build options. Limit the short list to three or four candidates to make comparison manageable.

Obtain CVs and recent appointments

Request current CVs that show recent arbitral appointments, relevant case types, publications and languages. Recent appointment history shows how active the candidate is and gives insight into scheduling and procedural style.

Seek references and observe conduct

Ask for references from counsel who have appeared before the candidate and from co arbitrators where possible. Counsel can comment on procedural firmness, scheduling discipline and fairness. Attend a hearing or watch recordings if the arbitrator has recently presided over public proceedings.

Check disclosures carefully

Require candidates to complete a formal disclosure statement addressing relationships, financial interests and prior appointments. Ensure disclosures cover recent consulting, expert roles and public positions that might create perceived bias. Scrutinise any connections and ask follow up questions where necessary.

Discuss procedural approach and case management

Clarify how each candidate would manage timetabling, disclosure, expert evidence and hearing format. A short discussion helps reveal their approach to proportionality and cost control and shows whether they will adopt a strict or flexible management style.

Negotiate fees and terms

Discuss fee structure and seek written confirmation of rates, minimum charges and chargeable preparation and reading time. Address cancellation terms and availability for interim or emergency hearings. Consider proposing a cap on fees or a blended rate to manage cost exposure.

Drafting effective appointment and challenge provisions

Clear appointment mechanics

When drafting the arbitration clause or appointment agreement specify the number of arbitrators the method of appointment the appointing authority and a fallback for deadlock. Provide timelines for nominations and acceptances to avoid delay.

Challenge and replacement rules

Include procedures for challenges to arbitrators based on impartiality or independence and for replacement if an arbitrator withdraws or becomes unavailable. Specify timelines for raising challenges and for the appointing authority to decide.

Emergency and interim measures

Provide for emergency arbitrator procedures and for urgent court relief where needed. Specify whether the tribunal has express interim powers and whether parties waive immunity where permitted by law.

Common pitfalls to avoid

Relying only on reputation

Reputation matters but it does not guarantee fit. A highly respected arbitrator may lack the specific technical knowledge the dispute requires. Balance reputation with demonstrated sector expertise.

Ignoring availability

Failing to confirm availability can cause real delay. Ensure the chosen arbitrator has unconflicted time for the hearing window and for any necessary interim hearings.

Underestimating costs

Some arbitrators charge significant reading and preparation fees in addition to hearing day rates. Obtain full fee estimates and consider fee caps or staged approvals to avoid surprise bills.

Overlooking cultural fit

In international disputes cultural awareness and procedural expectations affect case tone and witness handling. Consider whether the arbitrator can manage cross border differences effectively.

Addressing challenges and removing an arbitrator

Grounds for challenge

Under the Arbitration Act 1996 parties may challenge an arbitrator for lack of impartiality bias or failure to disclose relevant facts. The challenge should rely on clear evidence of conflict or bias rather than tactical disagreement with decisions.

Timing and procedure

Raise challenges promptly once the grounds are known. Courts and institutions expect prompt action. Delayed challenges risk waiver and may harm the challenger’s credibility.

Replacement and continuity

If an arbitrator resigns or is removed, the appointing mechanism in the clause or the institution’s rules will determine replacement. The tribunal should manage continuity to minimise re hearing and avoid unnecessary repetition of evidence.

Diversity and modern appointment practice

Increasingly clients seek diverse tribunals that reflect gender and other diversity goals. Institutional lists and appointing authorities now publish diversity statistics and some clients make diversity a contractual prerequisite. Diversity programs broaden available talent and bring different perspectives to complex disputes.

When to use multiple arbitrators with mixed expertise

Complex disputes often require both legal and technical expertise. In those cases parties may appoint a legally qualified chair with two technical co arbitrators to ensure both legal coherence and technical accuracy. Mixed panels increase cost but can produce robust, well reasoned awards.

Working with counsel to choose an arbitrator

Counsel’s role in selection

Counsel should advise on suitability, likely procedural approach and fee expectations. Counsel can propose candidates, contact them for availability and obtain disclosure information. Choose counsel experienced in arbitration and familiar with the relevant industry.

Managing conflicts of interest through counsel

Counsel should perform due diligence on candidate disclosures and advise on any perceived conflicts. Counsel must identify past involvements that might create grounds for challenge and recommend solutions such as limited recusal or a different appointment.

Practical checklist for appointing an arbitrator

– Identify the dispute’s core needs: technical, legal, language and cultural.

– Decide on a single arbitrator or three person tribunal based on value and complexity.

– Short list candidates with relevant experience, availability and fee estimates.

– Obtain CVs, disclosure statements and references from recent counsel.

– Discuss procedural approach including timetable disclosure and expert evidence.

– Instruct counsel to file formal appointments with the institution or appointing authority promptly.

Conclusion

Choosing the right arbitrator shapes the course and cost of arbitration. Parties in England and Wales should prioritise relevant expertise, procedural style, availability and impartiality when appointing an arbitrator. Clear appointment clauses, careful vetting, early discussions about case management and fee transparency reduce the risk of delay and help control cost. In high value or complex disputes consider mixed panels that combine legal and technical skills, and make diversity a factor in selection. Early involvement of experienced counsel speeds the appointment process and protects the integrity of the tribunal.
