How to Choose an Arbitrator (TRW 2025 Playbook)
Choosing the right arbitrator can decide your case long before opening statements. Arbitrators control the timetable, rule on evidence, shape the hearing, and write the award. A strong arbitrator selection process is therefore not a “nice to have”—it is the heart of an effective international arbitration strategy.
This guide distills Tahmidur Remura Wahid (TRW) Law Firm’s approach to arbitrator selection across commercial, investment, and construction disputes. We explain: how to decode appointment mechanics in your clause, how to build and narrow a targeted shortlist, what to ask in pre-appointment interviews (without crossing ethical lines), when to push for a sole arbitrator versus a three-member tribunal, how to weigh impartiality and conflicts, and how to calibrate for different seats (London, Singapore, Hong Kong, Paris, Dubai) and institutions (ICC, SIAC, HKIAC, LCIA, CIETAC, ICDR, ICSID). We also share a practical scoring matrix that our clients deploy to turn preferences into defendable, data-informed choices.
Why TRW? Our bilingual, cross-border arbitration teams have led complex cases across Asia, the Middle East, and Europe. We win appointment battles by preparing early, aligning seat law and institutional rules with your business objectives, and fielding arbitrators whose case management philosophy fits your case theory. For a primer on cross-border arbitration strategy, see: International Arbitration — TRW.
1) Start Where the Power Lies: Your Arbitration Clause

Before you ever assemble a shortlist, read the clause. Your clause defines who appoints, when, and how many arbitrators sit.
A. Identify the Appointment Protocol
- Institution & Rules: Which rules govern (e.g., ICC, SIAC, HKIAC, LCIA, CIETAC, ICSID)? The rules often prescribe default appointment methods and timelines.
- Number of Arbitrators: Sole arbitrator vs. three-member tribunal. If the clause is silent, institutional rules or the administering body typically decide based on dispute complexity/value.
- Method of Appointment:
- Party-party appointment (each side picks one; those two select the chair).
- List or ranking method (institution proposes a list to rank/strike).
- Institutional appointment (the institution selects, sometimes after party nominations).
- Nationality Constraints: Many clauses and rules require the chair to be of a different nationality than the parties. Watch for hidden constraints where a party’s affiliate nationality may be deemed relevant.
- Seat of Arbitration: The seat’s law affects challenges, replacement, and the court’s supportive powers. Align your candidate profile to the seat’s legal culture.
B. Anticipate Pathologies (and Cure Them Early)
- Ambiguous wording about “arbitration commission” vs. “institution” can create appointment friction. Pre-agree with your opponent (in writing) on the specific institution and appointment steps, without conceding jurisdictional positions.
- Multi-tier clauses (negotiation/mediation pre-steps) can delay appointments if not documented. Maintain compliance logs (emails, meeting notes) to prove conditions precedent were met.
- Consolidation & joinder: If multiple related contracts exist, check whether your clause (and the institution’s rules) allow the chair or institution to consolidate or join parties; this may influence the optimal chair profile.
2) Decide the Tribunal Structure: Sole vs. Three Arbitrators
A. Sole Arbitrator
When to prefer: Moderate value; focused legal issues; time-sensitivity; desire for lower costs.
Upside: Faster, cheaper, fewer scheduling conflicts.
Risk: No internal deliberation—a single decision-maker whose approach must fit your case.
B. Three-Member Tribunal
When to prefer: High stakes; complex factual/technical matrix; sensitive seats; need for a balanced bench (e.g., diverse legal traditions or industry expertise).
Upside: Deliberative quality control (peer review), specialist chair, legitimacy for delicate issues (public policy, regulatory overlay).
Risk: Cost, scheduling complexity, longer timetables.
TRW heuristic: If the facts are dense, quantum complex, or public policy could be invoked, push for three. If the dispute is document-light with a crisp legal issue and you want a swift path to award, a sole arbitrator may be optimal.
3) Build a Targeted Longlist: What Actually Matters
When we curate longlists, we do not start with fame. We start with fit. The right arbitrator for a FIDIC delay claim is rarely the right arbitrator for an FX-derivatives close-out dispute. We score seven dimensions:
- Subject-Matter Fluency
- Construction delay & disruption; energy offtake; JV and shareholder disputes; M&A post-closing adjustments; trade/commodities; finance/derivatives; tech/IP; franchise/distribution.
- Look for published awards, procedural orders, or scholarly writing aligned with your issues (without telegraphing bias).
- Seat & Legal Tradition Familiarity
- Common law seats (London, Singapore, Hong Kong) vs. civil law seats (Paris, Zurich).
- For PRC law disputes or CIETAC cases, bilingual capacity (or proven track record with bilingual hearing management) is invaluable.
- Procedural Philosophy
- Pro-active case management (tight timetables; limited adjournments; early identification of issues) vs. hands-off style.
- Attitude to document production: IBA-style proportionality vs. conservative disclosure.
- Use of hot-tubbing for experts; appetite for summary disposition; openness to virtual/hybrid hearings.
- Impartiality/Independence
- History of repeat appointments (by which parties/firms?); prior counsel roles for affiliates; potential issue conflicts (strong published views that touch your central questions).
- Nationality dynamics for chair roles when parties are from different states.
- Availability & Bandwidth
- Current caseload; hearing calendars; turnaround times for procedural orders and awards.
- Track record of timely awards.
- Communication & Hearing Management
- Clear, structured procedural orders; calm handling of objections; fairness to both sides; successful management of interpreters, live translation, and real-time transcription.
- Diversity and Perception
- Tribunal legitimacy improves with diversity of background, legal culture, and gender. Many institutions consider this in appointments; factoring it in proactively can aid acceptability and reduce challenge risk.
Sources of insight: institutional case experience, publicly available awards or articles, conference panels, counsel feedback, and prior dealings (all without breaching confidentiality). We never rely on a single datapoint.
4) Narrowing to a Shortlist: From Ten Names to One
Longlists become shortlists once we layer case-specific filters:
- Language profile: Do they work comfortably in the proceeding’s language(s)? Are they effective with simultaneous interpretation?
- Evidence profile match: If your case turns on critical path analysis, you want a chair who has seen and tested delay models. For finance, someone comfortable with valuation and close-out mechanics.
- Challenge-proofing: We run a conflicts check (including affiliates) and an issue-conflict scan (e.g., articles they wrote on a legal doctrine central to your case).
- Opponent’s likely choices: Anticipate your counterparty’s nominations and evaluate whether your candidate can work constructively with their pick—especially for a chair selection.
Three-name shortlist: For party nominations (co-arbitrator), we typically present 3 names with full dossiers: CV, representative cases, procedural tendencies, availability, potential disclosure points, and a pre-interview question set.
5) Pre-Appointment Interviews: What You Can (and Cannot) Ask
Most institutions allow limited, non-substantive party interviews before appointment, especially for chairs. The purpose is to assess suitability and availability, not to argue your case.
A. Permissible Topics
- Conflicts and availability timeline.
- General approach to case management: scheduling, procedural economy, openness to bifurcation/early merits, comfort with virtual hearings.
- Familiarity with relevant industry practices (without addressing your specific facts).
- Comfort with bilingual bundles and interpreter management.
B. Off-Limits Topics
- Merits of your case or likely rulings on specific issues.
- Sharing privileged strategy or documents.
- Seeking commitments on evidentiary rulings or burden allocations.
TRW’s interview script (extract):
- “How do you approach document production in cross-border cases to balance proportionality and fairness?”
- “In expert-heavy disputes, what’s your practice on concurrent evidence (hot-tubbing)?”
- “What is your usual timetable from CMC to hearing in a three-member tribunal?”
- “What is your practice on post-hearing briefs and closing sessions?”
- “Are there any foreseeable constraints in the next 12 months that could affect award drafting timelines?”
We memorialise interviews in a neutral note and circulate internally to ensure transparency.
6) Chairs vs. Party-Appointed Arbitrators: Different Jobs, Different Profiles
A. The Chair (Presiding Arbitrator)
- Sets the tone: timetable, evidentiary scope, tribunal questions, and deliberation structure.
- Needs gravitas and procedural discipline.
- Should be neutral to both parties’ legal cultures (often of a different nationality).
- For complex matters, choose a chair who has written clear awards in your subject area.
B. Party-Appointed Arbitrator
- Must be independent and impartial—not your advocate.
- Value add: helping the tribunal frame the issues, ensuring your case receives a fair hearing, and contributing to coherence in deliberations.
- Profile: someone who understands your industry, can interact productively with the chair and the other co-arbitrator, and communicates precisely.
Complementarity: We often build a tribunal with complementary strengths: e.g., a chair with deep procedural leadership, your co-arbitrator with industry fluency, and an opponent’s co-arbitrator with strong seat-law expertise—yielding a balanced bench.
7) Conflicts, Disclosures, and Challenges: Keeping the Award Safe
A. Conflicts Hygiene
- Check past engagements involving parties, affiliates, funders, parent/subsidiary entities, and opposing counsel.
- Screen for repeat appointments patterns (same party/counsel). Repetition alone is not fatal, but patterns can be grounds for concern.
B. Disclosures
- Encourage prospective arbitrators to err on the side of disclosure. Over-disclosure beats under-disclosure.
- Record disclosures in writing; assess whether any could give rise to justifiable doubts about impartiality.
C. Challenge Strategy
- Challenges are serious tactical events. Frivolous challenges backfire (delay, cost, credibility).
- Grounds typically involve undisclosed relationships, issue conflicts, or conduct giving rise to justifiable doubts.
- Prepare evidence-backed challenge submissions if needed, and consider settlement dynamics—sometimes agreeing to a replacement is wiser than litigating a marginal challenge for months.
8) Institution-Specific Nuances (Practical Notes)
- ICC: Scrutiny of awards increases quality and time predictability; the ICC Court often appoints the chair if parties cannot agree.
- LCIA: Parties nominate; the LCIA makes the final appointment. Expect robust case management directions and reasoned decisions on costs.
- SIAC: Efficient, popular for Asia-Pacific disputes; strong emergency arbitrator framework.
- HKIAC: Sophisticated with document production, consolidation, and hybrid hearing options; excellent for China-related cross-border disputes.
- CIETAC: Excellent for mainland-China disputes; preservation measures via PRC courts; bilingual hearing management is critical.
- ICDR/AAA: Useful for trans-Pacific and North American parties; consider chair’s U.S. discovery sensitivity when calibrating document production.
- ICSID: Investment arbitration against States/state entities; nationality constraints matter; chair neutrality is paramount; track record on jurisdiction/annulment is crucial.
9) Timing, Default Appointments, and Losing the Race to the Clock
Miss an appointment deadline, and you may lose your nomination right. Institutions act quickly to avoid paralysis.
TRW practice:
- Pre-clear two alternates** for each nomination in case availability or conflicts emerge late.
- Serve notices through all permitted channels (email + courier + any contractually agreed enterprise platforms) to cut off later “no notice” arguments.
- If the other side stonewalls the chair selection, escalate early to the institution for appointment rather than letting the case drift.
10) Evidence-Driven Fit: Align the Arbitrator with Your Proof
Arbitrators often decide credibility and weight more than admissibility. Match arbitrator expertise to your proof:
- Delay/Disruption (Construction): Chairs comfortable with Windows/Impacted As-Planned and earned value analysis; open to expert conferencing.
- Finance/Valuation: Chairs and co-arbitrators who engage with DCF, market multiples, or event studies and can parse netting/close-out mechanics.
- Tech/IP: Comfort with source code escrow protocols, FRAND-style damages (if relevant), and protecting confidential tech at hearing.
11) Culture, Language, and Hearing Dynamics
- Bilingual hearings require discipline: page-pinpointing, interpreter preparation, bilingual exhibit lists, and real-time transcription.
- Choose arbitrators who run bilingual proceedings smoothly—this is not merely a language skill; it is a management skill.
- For remote witnesses, pick arbitrators who have a clear protocol for virtual cross, breaks, and document display control.
12) Settlement Windows and “Med-Arb” Sensitivities
- Some institutions and seats accept med-arb (mediation within arbitration). If settlement is plausible, a chair with constructive settlement management experience can be valuable.
- Conversely, if you anticipate narrow liability and want a crisp award, prefer chairs who channel settlement off-record to avoid blurred lines.
13) When the Institution Appoints: Steering Without Steering
If the appointment falls to the institution (e.g., parties cannot agree on a chair):
- Provide the institution a neutral, precise profile of the desired chair (skills, languages, availability constraints, industry familiarity).
- Avoid overt advocacy. Institutions are receptive to functional criteria that ensure efficiency and fairness.
14) Arbitrator Fees and Cost Control
- Compare hourly vs. ad valorem frameworks across institutions; some allow fee caps.
- A disciplined chair will maintain lean procedural calendars, limit duplicative expert work, and keep the parties on track.
- During interviews, ask about cost management practices (without discussing your case specifics).
15) TRW’s Decision Matrix (Make the Choice Defendable)
We convert preferences into a scored comparison so in-house teams can defend their choice to boards and auditors. Typical weights (adjust to your case):
- Subject-matter / industry fit — 20%
- Seat & legal tradition familiarity — 15%
- Procedural philosophy & efficiency — 20%
- Independence / impartiality confidence — 15%
- Availability & timetable reliability — 15%
- Language & bilingual hearing management — 10%
- Diversity & tribunal chemistry — 5%
Each candidate receives a 1–5 score against each criterion, multiplied by weights. We keep commentary to justify each score.
16) Special Situations
A. Multi-Contract / Multi-Party
Draft for consolidation/joinder at contract stage, then prioritise chairs who have run consolidated arbitrations without due-process blow-ups.
B. Emergency Relief
If you may seek asset or conduct preservation, pick a chair who coordinates well with emergency arbitrators and with court applications (where allowed).
C. Regulatory-Sensitive Disputes
In sectors like energy, telecoms, or finance, prudence and public policy antennae matter. Select chairs with measured language and careful due-process records to reduce set-aside risk.
D. State/State-Linked Counterparties
For state entities, nationality rules and perceptions of neutrality are elevated. Chairs with state-dispute experience and steady drafting styles help awards survive scrutiny.
17) Common Mistakes to Avoid
- Hiring fame, not fit: Big names don’t always mean available or aligned with your case theory.
- Ignoring availability: A brilliant arbitrator with no calendar is a liability.
- Over-orchestrated interviews: Pushing the merits can taint the appointment.
- Underestimating bilingual complexity: Sloppy translations and disorganised exhibit management bleed credibility.
- Neglecting challenge risk: Failing to vet repeat appointments or issue conflicts can doom the tribunal months later.
18) Putting It Together: A 10-Day TRW Sprint Plan
Day 1–2: Clause analysis; seat law snapshot; institution rules cheat-sheet; tribunal structure decision.
Day 3–4: Longlist build; conflicts pre-screen; availability probes (informal).
Day 5: Client workshop to agree weighted criteria; cut to shortlist of 3 per slot (co-arbitrators) and 3 chair profiles.
Day 6–7: Conduct non-substantive interviews; final conflicts confirmations and disclosure canvass.
Day 8: Scorecard session; select nominee(s); prepare nomination package with CVs, statements of independence, availability confirmations.
Day 9: Serve nomination; propose chair candidates (or profile) to institution/opponent.
Day 10: Fallback planning if counterpart refuses to engage; escalate to institution where needed.
19) Case Study Snapshots (Anonymised)
- JV Post-Closing Claims (Asia seat; three-member tribunal): We nominated a co-arbitrator with deep corporate governance experience and strong bilingual hearing skills; the institution appointed a chair known for tight timetables. Result: liability split early via partial award; final quantum award within 11 months.
- EPC Delay/LDs (Middle East seat; three-member): Chair had decades of FIDIC experience and a proven protocol for hot-tubbing. Tribunal cut through expert stalemate with focused questions; award issued under 12 months with detailed causation findings.
- Tech Licensing (Hong Kong seat; sole): We agreed a sole arbitrator with a tech/IP background and firm control of confidentiality regimes. Award in 8 months, including injunctive undertakings.
These outcomes hinged on tribunal fit, not theatrics.
20) FAQs
Is it acceptable to propose national candidates from my side’s country?
Often for co-arbitrators, yes—subject to independence and conflicts. Chairs typically must be of a different nationality than the parties. Confirm rule specifics.
Can I influence the institution’s chair appointment?
You can submit a neutral chair profile describing skills and availability needed. Keep it functional and even-handed.
Should we always pick lawyers over engineers or accountants?
For the chair, usually a seasoned arbitrator (often a lawyer) is best. For co-arbitrators, sector experts who are experienced arbitrators can add enormous value if the dispute is technical.
Can we change arbitrators mid-case?
Yes, if a valid challenge succeeds or if an arbitrator becomes unable to act. Replacement can be disruptive; build robust tribunals from the outset.
