Behind the Curtain: A Step-by-Step, Business-Savvy Guide to ICC Arbitration

Prepared by Tahmidur Remura Wahid (TRW) Law Firm — Dhaka • Dubai • London

International arbitration under the ICC Rules is designed to be predictable, efficient, and enforceable. Yet for many first-time users—and even for seasoned in-house teams rotating in from other dispute forums—the process can feel opaque. This guide lifts the curtain on what actually happens from the moment you decide to file through to enforcement of the award, adding practical, seat-agnostic tips drawn from daily casework, and flagging the decisions that truly change cost, timing, and leverage.

If you want a companion talk-through tailored to your contract and governing law, start here: International Arbitration, ICC Arbitration at TRW, Construction Arbitration, Enforcement of Arbitral Awards, or Contact TRW.

1) Before you file: pre-arbitration triage (the 10-day sprint)

Well before Article 4 paperwork, the smartest teams run a compact “10-day sprint” to lock in leverage:

1. Clause check. Confirm institution (ICC), seat, governing law, language, tribunal size, joinder/consolidation rights, multi-contract coordination, escalation steps (amicable negotiation/mediation), and electronic service authorisation.
2. Arbitration agreement scope. Make sure your claims (contract, tort, unjust enrichment, misrepresentation, guarantees) sit inside the clause’s scope.
3. Asset map. Identify banks, receivables, ships, inventory, and payors you can reach post-award; if urgent, consider court interim relief at the seat or where assets are located.
4. Evidence spine. Build a chronology with contemporaneous documents, not post-hoc narratives; list custodians and system repositories.
5. Quantum model. Draft a working damages model linking documents → assumptions → outputs.
6. Arbitrator profile. Draft a realistic chair/co-arbitrator profile (industry, language, procedure preferences, availability).
7. Budget & timetable. Estimate institution/tribunal fees, counsel, experts, translation, hearing venue/tech.
8. Settlement architecture. Prepare staged payment, security alternatives, and mutual releases—because arbitration often catalyses settlement.
9. Cyber & confidentiality. Decide document sharing platforms, access control, and any confidentiality rings for trade secrets/PHI.
10. Communications protocol. Only counsel talk to the other side about the dispute; internal messaging avoids “bad documents”.

If you need a lightning review of your clause and evidence spine, see International Arbitration.

2) Article 4 — the Request for Arbitration (RFA): how to file with advantage

What it is. Your RFA triggers the case, starts deadlines, and sets an early narrative. You submit it to the ICC Secretariat with the USD 5,000 filing fee and include: parties and representatives, a concise dispute summary, relief sought with amounts, copies of the arbitration agreement(s) and contract(s), any nomination (sole arbitrator or co-arbitrator), and proposals on seat, law, and language.

What it isn’t. The RFA is not your full case. Keep it lean yet strategic—credible facts, clear jurisdictional basis, high-level quantum, and a sensible arbitrator nomination aligned with the dispute.

Practical tips.

• Attach the arbitration agreement and any amendments/assignments/novation; include multi-contract and chain of contracts logic if you seek consolidation or joinder later.
• If you anticipate emergency relief, mention the need and be ready to file an Emergency Arbitrator (EA) application under the Rules.
• Propose a sole arbitrator only if the dispute is truly contained (e.g., single issue/low complexity). Otherwise, a three-member tribunal typically reduces risk on complex merits and quantum.

3) Secretariat intake, notification, and Article 5 — the Answer

The Secretariat acknowledges receipt and notifies the respondent, ordinarily giving 30 days for an Answer. The Answer is the respondent’s moment to get organised without over-committing: identity and representatives, comments on the dispute and relief, position on number/choice of arbitrators, and observations on seat/law/language. It may include counterclaims and jurisdictional objections.

Extensions. The Secretariat may grant a short extension if requested before the deadline, typically expecting at least the respondent’s arbitrator nomination (for three-member tribunals).

No Answer? The case still proceeds. Silence does not waive participation; it just forfeits early influence (notably on the tribunal).

Counterclaim strategy (for claimants and respondents).

• Respondents: counterclaims can alter advance on costs, tribunal expertise, and timetable—use judiciously.
• Claimants: be ready with a 30-day reply to counterclaims. If counterclaims widen the terrain, reassess whether a sole arbitrator remains suitable.

4) The money question — provisional advance and advance on costs

Soon after filing, ICC will call for a provisional advance. When the case file and claim values are clearer, the Court fixes the advance on costs, usually split 50/50 between claimant and respondent. As complexity/value change, the Court may seek supplementary advances. If a party won’t pay, the other may step in; otherwise, the case (or a part) can be suspended or terminated.

Cashflow tactics.

• If the other side delays paying, consider paying their share to keep pace—then ask the tribunal to account for that in costs shifting.
• For SMEs, decide early whether to front advances or to structure staged settlement to avoid deadlock.

5) Tribunal constitution — the most consequential “hiring decision” you’ll make this year

Sole vs. three-member tribunal. Parties can agree; failing agreement, the Court decides based on complexity and value. Three-member tribunals add cost but usually deliver richer deliberation and perceived legitimacy in high-stakes matters.

Nominations and appointments.

• Sole arbitrator: the parties should jointly nominate; if they can’t, the Court appoints.
• Three-member tribunal: each party nominates one co-arbitrator; those two select the chair. If they cannot, the Court appoints. The Court confirms all appointments, considering nationalities, availability, independence, and expertise.

Our shortlists. We build shortlists with industry fluency, procedural style, and speed in mind. A brilliant jurist with a twelve-month backlog is not a good fit for an urgent EPC dispute. If you want help shaping a shortlist, see ICC Arbitration at TRW.

6) First case management conference (CMC) and Terms of Reference (ToR)

ToR is the ICC hallmark. Within ~30 days of file transmission to the tribunal, parties and tribunal sign the Terms of Reference: parties, claims/relief, issues to be decided, procedural foundations. The ToR locks the scope and discourages late ambushes.

At the CMC, you should finalise:

• Procedural Timetable (pleadings, document production, witness/expert stages, hearing dates).
• Document production regime (IBA Rules or tailored controls; Redfern or Stern schedules).
• Confidentiality and data protection, including any cybersecurity protocol.
• Hearing format (in-person, hybrid, virtual), transcription/interpretation needs, and time allocation method (e.g., chess-clock).
• Settlement/Mediation windows, if useful (the ICC ADR Centre is an option; you can schedule a “without prejudice” interval after document production).

Expedited Procedure Provisions (EPP). If your case falls under EPP (by value or party agreement), ToR may be dispensed with, written submissions are streamlined, and hearings may be limited or documents-only. For fit assessment, visit International Arbitration.

7) The written phase — where most cases are actually won

Typical sequence: Statement of Claim → Statement of Defence (+ Counterclaim) → Reply → Rejoinder, sometimes with a separate witness/expert phase. Most tribunals read deeply; precision here reduces the hearing to clarification rather than first principles.

Witness statements. Treat them as narratives tethered to documents. Avoid advocacy in witness voices. Where civil-law chairs sit, brevity and document anchoring are especially valued.

Expert reports. Scope carefully. In construction, plan for delay (Windows/As-Planned vs. As-Built, TIA, or Measured Mile) and quantum (cost build-up, prolongation, disruption); in finance, valuation comparables and discount rate logic; in sale of goods, pricing indices and mitigation evidence.

Privilege and confidentiality. Align team practices with the highest common denominator of applicable privilege rules. In cross-border teams, one casual email can waive privilege under one law. Set a protocol at the CMC.

Translations. Translate only what matters. Certified where necessary. Keep consistency in defined terms, measurement units, and names.

8) Document production — targeted, not discovery

ICC arbitrations do not default to wide-ranging discovery. Tribunals lean toward targeted, relevant, material document production. Requests are made via Redfern/Stern schedules: identify the category, explain relevance and materiality, and address proportionality. Tribunals may allow redactions and confidentiality rings.

Strategy tips.

• Ask for categories, not “all documents.”
• Tie each request to a specific issue on which you bear or shift the burden.
• Resist with specific objections (irrelevance, disproportionality, privilege, confidentiality).
• If you anticipate sensitive production, propose a data room and access tiers early.

9) The hearing — design, not default

Not every case needs a hearing, but most do. The best hearings are engineered:

1. Agenda & chess-clock. Pre-agree time allocations; keep openings tight and visual.
2. Witness order. Logical flow; group witnesses by theme.
3. Examination style. Use cross-examination for credibility and gaps, not to repeat written cases.
4. Expert hot-tubbing. Concurrent evidence can crystallise differences fast; agree question lists to structure it.
5. Hybrid logistics. If virtual/hybrid, specify platform, hardware, backup lines, screen-share etiquette, breakout rooms, and time zones.
6. Hearing bundles. One core bundle with sightlines and clean document IDs; avoid duplication.
7. Interpreter protocols. Test glossaries and hardware; never discover latency on Day 1.
8. Public policy and seat-specific points. If seat issues (e.g., confidentiality or mandatory law) matter, build them into the hearing plan.

Pre-hearing conference. Use it to clear late objections, finalise witness order, and lock technical settings.

10) After the hearing — post-hearing briefs (PHBs) and costs

PHBs allow you to tie transcripts and exhibits back to outcome-determinative issues. Keep them short, cite transcript page/line and exhibit IDs, and avoid re-arguing settled points.

Costs submissions. Provide a schedule of costs (legal fees, experts, hearing/disbursements, institution/tribunal fees paid), and argue allocation based on success, conduct, and efficiency. Tribunals often respond to measured asks linked to procedural behaviour (e.g., a party’s refusal to narrow issues or serial delay).

11) Closing, deliberations, and the ICC Court’s scrutiny

When the record is complete, tribunals close the proceedings and begin deliberations. In three-member tribunals, expect a collegial method (sometimes with drafts by the chair). The ICC Court then scrutinises the draft award—a unique quality check that reduces clerical errors, reasoning gaps, and annulment risks.

Timing. The Rules encourage awards within six months of ToR, but extensions are routine in complex cases. Ask the tribunal for an indicative timeline and build stakeholder expectations accordingly.

12) The award — correction, interpretation, and additional award

Final awards set out findings, reasoning, relief, and costs. After notification, parties have a short window to request:

• Correction of typographical/computational errors.
• Interpretation of ambiguous parts.
• Additional award on claims pleaded but inadvertently omitted.

These are not appeals. There is no merits appeal inside ICC. Any attempt to relitigate substance will be rejected.

13) Enforcement (and resistance): make the award pay

Thanks to the New York Convention, ICC awards are enforceable in most trading states. The playbook:

1. Voluntary compliance window. Send a measured demand with wire instructions and a draft satisfaction of judgment/award.
2. Parallel pressure. Where appropriate, file recognition and enforcement where the debtor banks or invoices; coordinate filings to land within a tight window.
3. Security and stays. If the debtor seeks a set-aside at the seat and a stay, argue conditions (e.g., bank guarantees).
4. Ex parte relief. Consider attachment or freezing orders where available.

If you expect to enforce in South Asia or the Gulf, a Dhaka–Dubai–London strategy often yields the most practical leverage; see Enforcement of Arbitral Awards.

14) Special topics that often decide the margins

A) Emergency Arbitrator (EA) and interim measures

EA is available before tribunal constitution for urgent relief (status quo, asset preservation). After constitution, the tribunal can order interim measures; in parallel, courts at the seat or asset location may still grant conservatory relief without undermining the arbitration.

When it works: imminent dissipation, abusive calls on guarantees, irremediable supply chain damage. When it doesn’t: purely monetary harm compensable by damages.

B) Multi-party, multi-contract cases

Think joinder (bringing in a parent/guarantor) and consolidation (merging parallel ICC cases under compatible clauses). Get your paperwork aligned early—show the same legal relationship, compatible arbitration agreements, and overlapping facts.

C) Settlement leverage without losing momentum

Schedule “without prejudice” windows at logical points (post-document production; pre-or post-hearing). Use mediators where parties need a third voice. Always prepare a term sheet with security, payment schedule, tax treatment, and withdrawal mechanics.

D) Confidentiality & data protection

Arbitration is private; formal confidentiality depends on the Rules and orders. For sensitive sectors, add confidentiality undertakings, secure repositories, and access tiers (counsel-only, expert-only).

E) Tribunal secretary and efficiency

A capable secretary can streamline logistics and draft background sections. Parties should consent to scope and receive transparency on time spent.

F) Costs control that actually works

• Match tribunal size to complexity.
• Push early for issues lists to narrow proof.
• Consider document-only determination of discrete quantum items.
• Use hot-tubbing to avoid duelling monologues.

16) Myths vs. realities

“ICC is always slower than other institutions.”
Not invariably. Good case management, realistic timetables, and a decisive chair matter more than the logo. The ICC Court’s scrutiny phase often prevents post-award headaches.

“Three arbitrators always double the cost.”
Three members do cost more in fees, but better deliberation and stakeholder acceptance frequently outweigh the delta in complex or high-exposure matters. For simple debt claims, a sole arbitrator is sensible.

“Document production is discovery.”
No. ICC targets material categories. Tribunals routinely strike fishing expeditions and protect confidentiality with rings/redactions.

“Emergency Arbitrator guarantees protection.”
EA relief is exceptional and depends on urgency, necessity, and proportionality. Prepare evidence of imminent harm and why money damages later won’t cure it.

“Awards are easy to enforce everywhere.”
The Convention helps, but local courts and assets decide timelines and tactics. Enforcement planning should start at clause drafting—not after you win.

17) What really drives outcome (and cost)

From our vantage point, five factors move the needle:

1. Tribunal quality and availability. The best chairs keep cases tight, cut noise, and focus the record on what matters.
2. Document discipline. Chronologies and bundles that tell the story—without bloat—shorten hearings and sharpen awards.
3. Expert credibility. Tribunals spot advocacy masquerading as expertise. Pick measured, independent experts.
4. Issue narrowing. Agree on what isn’t in dispute. It buys you credibility for the issues that are.
5. Enforcement-first thinking. Draft claims and relief your enforcement forum will respect. Winning the wrong relief is losing.

18) A word on seats: London, Dubai, Singapore, Paris—and your enforcement corridor

The seat determines the curial law and the court that can set aside or assist. Pick a seat that aligns with asset geography and supportive courts. Examples:

• London: robust interim relief, disclosure tools in aid of enforcement, deep bench of arbitration-savvy judges.
• Dubai (DIFC)/Abu Dhabi (ADGM): modern arbitration regimes and effective routes for GCC banking enforcement.
• Singapore: efficient procedures, pro-enforcement jurisprudence, excellent hearing infrastructure.
• Paris: long-standing neutrality, sophisticated court support.

Map seat choice to your counterparties’ banks and receivables. For multi-hub strategies bridging South Asia and the Gulf, see International Arbitration.

19) Sample timelines (indicative, not prescriptive)

• Day 0: RFA filed; filing fee paid.
• ~Day 1–5: Secretariat acknowledges and notifies.
• ~Day 30: Answer due (extensions possible).
• ~Month 2–4: Tribunal constituted.
• ~Month 4–5: CMC; ToR executed; timetable fixed.
• ~Month 5–9: Written phase + document production.
• ~Month 10–12: Hearing (if any).
• ~Month 12–15+: PHBs; costs; closure; deliberations.
• Thereafter: ICC scrutiny; award issuance.

Complexity, counterclaims, joinder, and interim measures can push or compress these milestones.
