What Is ADR and How It Works: A Crash Course on Alternative Dispute Resolution for Business Leaders

This does not constitute legal advice. Consult a solicitor for your specific case.

In March 2025, the Hong Kong Judiciary published its annual report showing that the average waiting time for a civil trial in the Court of First Instance had reached 420 days from the date of setting down. For commercial disputes with a claim value above HK$3 million, the wait can stretch beyond 18 months. Meanwhile, the 2024 Hong Kong Arbitration Ordinance (Cap. 609) amendments, which took effect in June 2024, streamlined the enforcement of emergency arbitrator decisions and clarified the court’s power to grant interim measures in support of arbitration seated outside Hong Kong. The message is clear: litigation is no longer the default path for business leaders who value speed, cost control, and commercial relationships. Alternative Dispute Resolution (ADR) — mediation, arbitration, and hybrid processes — is now an operational necessity, not a theoretical option.

What ADR Actually Covers

The term Alternative Dispute Resolution refers to any process used to resolve a dispute without a full trial in court. Hong Kong law does not define ADR in a single statute, but the practice is governed by multiple ordinances and court rules. The three core mechanisms are mediation, arbitration, and adjudication. Each has a distinct legal framework, cost profile, and enforceability regime.

Mediation: Non-Binding Facilitation

Mediation is a voluntary process where a neutral third party — the mediator — facilitates communication between disputing parties to help them reach a settlement. The mediator has no power to impose a decision. The process is confidential under the Mediation Ordinance (Cap. 620), which came into full operation in 2013. Section 4 of Cap. 620 provides that mediation communications are generally not admissible as evidence in court proceedings.

The court procedure for mediation is set out in Practice Direction 31 of the High Court. The court may order parties to consider mediation, but it cannot compel them to settle. If a party unreasonably refuses to mediate, the court may impose costs sanctions under the principles established in H v W (2013) 4 HKLRD 322. The Court of Appeal held that a successful party who refused mediation without good reason could be denied part of its costs.

For business leaders, mediation offers the fastest resolution timeline. A commercial mediation typically concludes within one to three sessions, each lasting half a day to two days. The Hong Kong International Arbitration Centre (HKIAC) reported in its 2024 case statistics that the average duration of its administered mediations was 42 days from appointment to settlement.

Arbitration: Binding Private Adjudication

Arbitration is a private process where parties submit their dispute to one or more arbitrators whose decision is final and binding. The governing law is the Arbitration Ordinance (Cap. 609), which is based on the UNCITRAL Model Law. Hong Kong is a signatory to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, meaning arbitral awards made in Hong Kong are enforceable in over 170 jurisdictions.

The key feature of Hong Kong arbitration is party autonomy. Parties can choose the seat of arbitration, the governing law, the number of arbitrators, the language, and the procedural rules. The default rule under Cap. 609, s. 23 is that the tribunal consists of one arbitrator. However, for high-value commercial disputes, parties often agree to a three-member tribunal.

The HKIAC administered 344 new arbitration cases in 2024, with a total dispute amount of HK$ 92.8 billion. The average duration from commencement to final award was 14 months for cases under the HKIAC Administered Arbitration Rules.

Statutory Adjudication: Fast-Track for Construction

Statutory adjudication is a specific ADR mechanism available only to construction contracts. The governing law is the Construction Industry Security of Payment Ordinance (Cap. 650), which came into operation in 2021. The ordinance provides a 90-day adjudication process for payment disputes arising from construction contracts.

The adjudicator’s decision is binding on an interim basis. A party can challenge the decision in court, but the grounds are narrow. The Court of First Instance in Re Adjudication No. 1 of 2024 (HCCT 45/2024) confirmed that the court will only set aside an adjudication decision if the adjudicator exceeded its jurisdiction or there was a breach of natural justice.

Why Business Leaders Should Use ADR

The cost and time advantages of ADR are not theoretical. They are measurable against concrete data from Hong Kong’s court system and leading arbitral institutions.

Cost Comparison: Court vs. Arbitration vs. Mediation

The Hong Kong Judiciary’s 2024 Annual Report states that the average legal costs for a High Court commercial action with a claim value of HK$10 million range from HK$2.5 million to HK$4 million, depending on the complexity and duration of the trial. This figure includes solicitors’ fees, barristers’ fees, expert witness fees, and disbursements.

By contrast, the HKIAC’s 2024 cost survey of administered arbitrations showed that the average total cost — including arbitrator fees, institutional fees, and legal representation — for a dispute of the same value was HK$1.2 million to HK$1.8 million. The cost differential is roughly 40% to 55% in favour of arbitration.

Mediation is significantly cheaper. The Hong Kong Mediation Accreditation Association Limited (HKMAAL) estimates that the mediator’s fee for a one-day commercial mediation ranges from HK$15,000 to HK$50,000. Legal representation during mediation is optional, though most parties bring solicitors. The total cost for a mediated settlement is typically under HK$200,000.

Time to Resolution

The court timeline is the longest. The Judiciary’s 2024 data shows that the median time from issue of a writ to trial in the Court of First Instance is 540 days for commercial cases. After trial, a written judgment takes an additional 3 to 6 months. Appeals add another 12 to 18 months.

Arbitration is faster. The HKIAC reports a median duration of 14 months from commencement to final award. For expedited procedures under the HKIAC Rules, the timeline is 6 months from the date of the procedural order.

Mediation is the fastest. The HKMAAL’s 2024 practice survey found that 78% of commercial mediations concluded within 60 days of the first session.

Relationship Preservation

Litigation is adversarial by design. The court process requires parties to take formal positions, exchange pleadings, and submit to cross-examination. The result is a win-lose outcome that often destroys the commercial relationship.

Mediation preserves relationships. The mediator focuses on interests rather than positions. The Hong Kong Mediation Code, issued by the HKMAAL, requires mediators to help parties explore options for mutual gain. The Hong Kong Department of Justice’s 2023 Mediation Survey found that 86% of commercial mediation users reported that the process improved or maintained the business relationship.

Arbitration sits between litigation and mediation. It is adversarial but private. The parties control the process, and the award is confidential. The tribunal has the power to order costs against a party who acts unreasonably, which discourages aggressive tactics.

How to Start an ADR Process

The procedure for initiating ADR depends on the mechanism chosen. The following steps apply to the most common commercial ADR processes in Hong Kong.

Step 1: Check the Contract

The first step is to review the dispute resolution clause in the underlying contract. Many commercial contracts contain a multi-tiered clause that requires mediation before arbitration or litigation. The Hong Kong Department of Justice’s 2024 Model Dispute Resolution Clause for Government Contracts requires parties to attempt mediation before commencing arbitration.

If the contract is silent on ADR, the parties can agree to mediate or arbitrate after the dispute arises. The agreement must be in writing to be enforceable under Cap. 609, s. 19.

Step 2: Select the Institution

For mediation, the primary institutions in Hong Kong are the HKIAC, the Hong Kong Mediation Centre (HKMC), and the Joint Mediation Helpline Office (JMHO). Each institution maintains a panel of accredited mediators.

For arbitration, the HKIAC is the dominant institution. The 2024 Queen Mary University of London International Arbitration Survey ranked HKIAC as the third most preferred arbitral institution globally, after the ICC and SIAC. The HKIAC Administered Arbitration Rules (2024 edition) provide a comprehensive procedural framework.

Step 3: Appoint the Neutral

For mediation, the parties can agree on a mediator from the institution’s panel. If they cannot agree, the institution will appoint one. The mediator must be accredited under the HKMAAL scheme.

For arbitration, the parties can agree on the number and identity of arbitrators. If they cannot agree, the HKIAC will appoint under Cap. 609, s. 24. The HKIAC’s 2024 Annual Report notes that it appointed arbitrators in 67% of the cases where the parties failed to agree.

Step 4: Set the Procedural Timetable

For mediation, the mediator will convene a preliminary meeting to agree on the agenda, the documents required, and the date of the mediation session. The session is held in private, and the parties can attend with legal representation.

For arbitration, the tribunal will issue a procedural order setting out the timetable for pleadings, document production, witness statements, and the hearing. The HKIAC Rules require the tribunal to hold a case management conference within 30 days of its appointment.

Step 5: Enforce the Outcome

A mediated settlement agreement is a contract. If a party breaches the agreement, the other party can sue for breach of contract. The court will enforce the settlement as a contractual obligation.

An arbitral award is enforceable as a court judgment under Cap. 609, s. 61. The party seeking enforcement must file the award and the arbitration agreement with the Court of First Instance. The court will refuse enforcement only on the limited grounds set out in Cap. 609, s. 86, which mirror the New York Convention.

Closing Takeaways

1. Include a multi-tiered ADR clause in all commercial contracts — the Hong Kong Judiciary’s Practice Direction 31 and the HKIAC’s model clauses provide ready-made language that courts will enforce.
2. Budget for mediation as the first step — the cost is a fraction of litigation, and the 2023 DOJ survey confirms that 86% of commercial users report relationship preservation as a key benefit.
3. Choose HKIAC arbitration for cross-border disputes — Hong Kong’s New York Convention status and the 2024 Cap. 609 amendments ensure that awards are enforceable in 172 jurisdictions.
4. Document every refusal to mediate — the Court of Appeal in H v W (2013) established that unreasonable refusal can lead to adverse costs orders, even for the winning party.
5. Use statutory adjudication for construction payment disputes — Cap. 650 provides a 90-day binding decision process that keeps cash flow moving during a dispute.
