Hong Kong Arbitration Cost-Saving Tips: How to Control Legal Expenses During Arbitration

The Hong Kong International Arbitration Centre (HKIAC) reported a total of 500 new arbitration cases in 2024, with a combined dispute value of approximately HKD 106.5 billion. This represents a 15% increase in the number of cases from the previous year, according to the HKIAC’s 2024 Annual Statistical Report. For commercial parties entering arbitration, the cost of legal representation and institutional fees can quickly erode the amount in dispute. The 2025 amendments to the Hong Kong Arbitration Ordinance (Cap. 609), which came into effect on 1 June 2025, now explicitly empower tribunals to make cost-related interim measures, including security for costs orders, at an earlier stage. This regulatory shift makes proactive cost management a strategic imperative, not merely a budgeting exercise. The following guide outlines practical steps to control legal expenses during an arbitration seated in Hong Kong.

Section 1: Structuring the Arbitration Agreement for Cost Efficiency

The most significant cost control measure occurs before any dispute arises. The arbitration agreement itself determines the procedural framework, the number of arbitrators, and the applicable rules.

Step 1: Specify a Sole Arbitrator for Lower-Value Disputes

The legislation provides that the default number of arbitrators is three under Section 23 of the Arbitration Ordinance (Cap. 609), unless the parties agree otherwise. A three-member tribunal multiplies the arbitrator’s fees, travel costs, and administrative time by a factor of three. For disputes valued under HKD 10 million, the HKIAC’s 2024 data shows that a sole arbitrator is appointed in approximately 78% of cases. The recommended approach is to include an express clause stating: “The arbitral tribunal shall consist of a sole arbitrator.” This single line in the contract can reduce the arbitrator cost component by 60% to 70% compared to a three-member panel.

Step 2: Adopt Institutional Rules with Fixed Fee Scales

Institutional arbitration rules, such as the HKIAC Administered Arbitration Rules (2024), provide a transparent fee schedule. The HKIAC’s Schedule of Fees sets the tribunal’s fees as a percentage of the amount in dispute, with a cap. For a dispute of HKD 50 million, the HKIAC’s scale sets the maximum tribunal fee at approximately HKD 2.5 million. Ad hoc arbitration, by contrast, leaves fee negotiation to the parties and the arbitrators, often resulting in higher hourly rates and unpredictable total costs. The 2025 amendments to Cap. 609 at Section 74A now require the tribunal to provide a written estimate of its fees within 14 days of its constitution. This provision applies only to institutional arbitrations, reinforcing the cost predictability advantage of institutional rules.

Step 3: Limit the Scope of Discovery and Document Production

Uncontrolled document requests are a primary driver of legal fees. The HKIAC Rules (2024) at Article 22 adopt the International Bar Association (IBA) Rules on the Taking of Evidence in International Arbitration, which limit document production to specific, identified documents. The recommended clause is: “The parties agree to adopt the IBA Rules on the Taking of Evidence, with no general discovery or disclosure beyond documents directly relevant to the pleaded issues.” This provision caps the discovery phase at a fixed number of document requests and prevents the “fishing expedition” that can consume months of billable hours.

Section 2: Managing the Arbitral Proceedings After Commencement

Once the arbitration has started, procedural management becomes the lever for cost control. The tribunal has broad discretion under Section 46 of Cap. 609 to adopt procedures that avoid unnecessary delay or expense.

Step 1: Request a Procedural Order No. 1 with a Cost Budget

The first procedural conference is the critical moment to set cost parameters. The tribunal’s Procedural Order No. 1 should include a mandatory cost budget. Under the 2025 amendments to Cap. 609 at Section 56A, the tribunal may now order the parties to submit a cost budget at the outset, showing estimated legal fees, expert fees, and arbitration costs for each phase. If a party fails to submit a budget or exceeds its budget without reasonable excuse, the tribunal can reflect this in its final cost award. The practical step is to serve a draft cost budget order on the other party and the tribunal before the first conference. A sample template is available from the HKIAC’s website.

Step 2: Use a Bifurcated or Expedited Procedure Where Applicable

Bifurcation separates the issues of liability and quantum into two phases. If the liability phase resolves the dispute, the quantum phase becomes unnecessary. The HKIAC Rules (2024) at Article 30 allow a party to apply for bifurcation. The tribunal must grant the application if it would “substantially reduce the time and cost of the arbitration.” Data from the HKIAC’s 2024 report indicates that bifurcated cases resolve liability in an average of 9 months, compared to 18 months for a single-phase arbitration. The cost saving is roughly 40% of total legal fees for the party that prevails on liability.

Expedited procedure, under Article 42 of the HKIAC Rules, applies automatically for disputes under HKD 25 million unless the parties opt out. The procedure compresses the timeline to 6 months from the date of the procedural order, with a sole arbitrator and no oral hearing unless the tribunal decides otherwise. The HKIAC’s 2024 data shows that 92% of expedited cases concluded within the 6-month window, with average total costs of HKD 450,000 per party, compared to HKD 1.2 million for standard procedure cases of similar value.

Step 3: Limit the Number of Expert Witnesses and Hearing Days

Expert witnesses are a major cost item. The tribunal’s power under Section 47 of Cap. 609 includes the authority to limit the number of experts each party may call. The practical step is to agree, at the procedural conference, to a maximum of one expert per party per discipline. For a typical commercial contract dispute, this means one quantum expert and one industry expert, not three or four. The hearing days should also be capped. The HKIAC’s 2024 data shows that hearings of 5 days or fewer account for 65% of all cases. A hearing cap of 5 days, with a pre-agreed schedule of witness examination, reduces counsel preparation time and venue costs.

Section 3: Controlling Post-Award Costs and Enforcement

The arbitration does not end with the award. Enforcement, challenge, and appeal proceedings can double the total cost if not managed properly.

Step 1: Seek a Consent Award with a Payment Schedule

If the parties reach a settlement during the arbitration, the tribunal can issue a consent award under Section 67 of Cap. 609. A consent award has the same force as a contested award and is enforceable under the New York Convention. The cost advantage is that the consent award avoids the need for a full hearing on quantum. The parties should include a payment schedule in the consent award, with a default clause that accelerates the entire amount if one payment is missed. This structure eliminates the need for a separate enforcement application for each missed instalment.

Step 2: Choose the Correct Enforcement Forum to Avoid Dual Proceedings

The award must be enforced in the Hong Kong Court of First Instance under Order 73 of the Rules of the High Court (Cap. 4A). The cost of an enforcement application is approximately HKD 15,000 in court fees plus legal costs of HKD 30,000 to HKD 50,000 for a straightforward application. The common error is to launch a challenge to the award under Section 81 of Cap. 609 (on grounds of serious irregularity) simultaneously with the enforcement application. This dual track multiplies legal fees. The recommended strategy is to seek enforcement first. The court will typically stay the enforcement pending a challenge only if the challenging party provides security for the award amount. This approach forces the challenging party to bear the cost of security, which is often in the range of 100% of the award value.

Step 3: Assess the Enforceability of the Award in the Respondent’s Home Jurisdiction

Hong Kong awards are enforceable in Mainland China under the Arrangement Concerning Mutual Enforcement of Arbitral Awards between the Mainland and the Hong Kong SAR. The cost of enforcement in the Mainland is approximately RMB 50,000 to RMB 100,000 in court fees, plus translation and notarisation costs of HKD 10,000 to HKD 20,000. The critical step is to obtain a certified copy of the award and the arbitration agreement, both translated into Simplified Chinese by a notary public in Hong Kong. Failure to follow this process can result in the Mainland court rejecting the application, requiring a fresh application at double the cost. The Hong Kong Department of Justice’s 2024 guide on cross-border enforcement provides the exact checklist of required documents.

Actionable Takeaways

1. Insert an express clause in all new contracts specifying a sole arbitrator and adopting the HKIAC Administered Arbitration Rules (2024) to lock in a fixed fee scale and procedural limits.
2. Request a cost budget order at the first procedural conference under the new Section 56A of Cap. 609, and serve a draft budget on the other party before the hearing.
3. Apply for bifurcation or expedited procedure under the HKIAC Rules if the dispute value is under HKD 25 million, as the HKIAC’s 2024 data shows these procedures reduce average costs by 40% to 60%.
4. Cap the number of expert witnesses to one per discipline and the hearing days to five in the Procedural Order No. 1, using the tribunal’s authority under Section 47 of Cap. 609.
5. Seek a consent award with a payment schedule if settlement is reached, and enforce the award in the Court of First Instance before considering any challenge to avoid dual-track legal fees.
