Two companies sign a supply contract, one delivers late, and the other wants millions in damages — but neither wants the file, the timeline, or the trade secrets aired in an open courtroom. In Malaysia, that is where arbitration and mediation take over from the courts.

Alternative dispute resolution (ADR) lets parties settle commercial disagreements privately, often faster and more flexibly than litigation, and — in the case of arbitration — with an award that is enforceable almost anywhere in the world. This guide covers the three pillars businesses rely on: the Arbitration Act 2005, the Asian International Arbitration Centre (AIAC), and mediation.

## What law governs arbitration in Malaysia?

The backbone is the **Arbitration Act 2005 (Act 646)**, which took effect on 15 March 2006 and replaced the older Arbitration Act 1952. It is drawn from the UNCITRAL Model Law on International Commercial Arbitration, the global template that makes an award made in Kuala Lumpur legible to courts in London, Singapore, or Shanghai. The Act governs both domestic and international arbitrations seated in Malaysia and, according to Aceris Law, has been amended "the first time in 2011 and twice in 2018," most recently by the Arbitration (Amendment) Act 2024.

The Act deliberately limits how far courts can interfere. Judges have a supervisory role only — they cannot re-hear the merits. But some powers cannot be contracted out: under Section 11, the High Court retains the power to grant interim relief, such as freezing assets, in support of an arbitration.

Everything starts with a **written arbitration agreement** — a clause in the contract (or a later stand-alone agreement) in which the parties consent to arbitrate rather than sue. Without it, there is no arbitration.

## What is the AIAC, and what does it do?

The **Asian International Arbitration Centre (AIAC)** is Malaysia's flagship arbitral institution, based in Kuala Lumpur. It was first set up in 1978 as the Kuala Lumpur Regional Centre for Arbitration (KLRCA), under the auspices of the Asian-African Legal Consultative Organisation, and renamed the AIAC in 2018. It administers cases from filing to award: appointing arbitrators, managing fees, and providing hearing facilities.

Its current rulebook is the **AIAC Arbitration Rules 2023**, effective 24 August 2023. The rules are organised in three parts — Part I (the AIAC's own rules), Part II (the UNCITRAL Arbitration Rules), and a set of Schedules — with Part I prevailing in any conflict. Under Rule 2(2), an arbitration formally commences when the AIAC receives the complete notice of arbitration with its supporting documents, not merely when the respondent is served.

For smaller matters, the Rules offer a **Fast-Track Procedure** (Schedule 4) with a compressed timetable:

| Feature | Fast-Track threshold / timeline |
| --- | --- |
| International disputes | Amount in dispute below USD 300,000 |
| Domestic disputes | Amount in dispute below RM 1,000,000 |
| Award deadline | Within 6 months of the tribunal's constitution |
| Maximum extension | Up to 9 months |

Beyond commercial cases, the AIAC also serves the construction sector: under the Construction Industry Payment and Adjudication Act 2012 (CIPAA), it appoints adjudicators — usually people with deep construction-law experience — to resolve payment disputes quickly.

## What changed under the Arbitration (Amendment) Act 2024?

The **Arbitration (Amendment) Act 2024** came into force on **1 January 2026** and modernised several parts of the 2005 Act. The headline changes:

- **Third-party funding (Sections 46A–46I).** A statutory framework now allows an external funder to finance all or part of an arbitration. Section 46C abolishes the old common-law rules against maintenance and champerty that previously cast doubt on such arrangements. A **Code of Practice for Third Party Funding** accompanies it, setting a capital-adequacy requirement of at least RM 10 million for funders.
- **Mandatory disclosure (Section 46G).** A funded party must disclose the existence of the funding arrangement and the funder's identity, so the tribunal can check for conflicts. If the agreement is signed after proceedings begin, disclosure is due within 15 days.
- **Electronic signatures (Section 33).** Arbitrators may now sign awards using digital or electronic signatures.
- **Automatically binding awards (Section 38).** An award is binding without a separate application for recognition.
- **Governing law of the arbitration agreement (Section 9A).** Where the parties have not chosen a law for their arbitration agreement, the default is the law of the seat of arbitration — resolving a long-running ambiguity.

The Act also introduced governance reform at the AIAC, establishing an AIAC Court of Arbitration and a President role.

## How do arbitration, mediation, and litigation compare?

Each route trades off differently on speed, cost, privacy, and finality. Mediation, promoted by the **Mediation Act 2012**, is a voluntary process in which a neutral mediator helps the parties reach their own settlement — nothing is imposed, and if it fails the parties keep every other option open. Arbitration ends in a binding award; litigation ends in a court judgment.

| Factor | Mediation | Arbitration | Litigation |
| --- | --- | --- | --- |
| Governing law | Mediation Act 2012 | Arbitration Act 2005 | Courts of Judicature Act 1964 and rules |
| Outcome | Settlement agreed by parties | Binding award | Binding judgment |
| Decision-maker | Neutral mediator (facilitates) | Arbitrator(s) chosen by parties | Judge |
| Privacy | Private and confidential | Private and confidential | Generally public |
| Cross-border enforcement | Depends on settlement terms | Wide, via the New York Convention | Depends on bilateral arrangements |
| If it fails | Escalate to arbitration or court | Award is final, limited appeal | Appeal within court hierarchy |

A practical warning: many contracts contain a **tiered dispute-resolution clause** requiring the parties to negotiate or mediate first, and only then arbitrate. Malaysian case law treats these "conditions precedent" as real obligations — skip the mediation step and your arbitration may be challenged.

## How are arbitral awards enforced?

This is arbitration's biggest advantage. Sections 38 and 39 of the Arbitration Act 2005 govern recognition and enforcement in Malaysia. An enforceable award must be written, signed, dated, reasoned, and identify the seat of arbitration.

Because Malaysia is a contracting state to the **New York Convention** on the Recognition and Enforcement of Foreign Arbitral Awards, an award made in Malaysia can be enforced in the other member states — the reach a domestic court judgment rarely has. The grounds for refusing enforcement are deliberately narrow: **Section 39** lists a closed set that mirrors Article V of the Convention, covering matters such as a party's incapacity, an invalid arbitration agreement, inadequate notice, or an improperly constituted tribunal.

Separately, a losing party may apply to **set aside** an award, but only on limited grounds — including where the dispute was not capable of settlement by arbitration or where the award conflicts with Malaysian public policy. Courts will not reopen the merits.

## What's next

If you are drafting a contract, decide now how disputes will be resolved: whether to arbitrate, which seat and institution (the AIAC and its 2023 Rules are the default choice for Malaysia-seated cases), how many arbitrators, and the governing law. A clear clause is far cheaper than a fight about where to fight. If a dispute is already live, check your contract for any mediation-first step before filing, and confirm your arbitration agreement is in writing.

For deeper reading, consult the Arbitration Act 2005 as amended, the AIAC Arbitration Rules 2023, and the Mediation Act 2012 directly, and take advice tailored to your contract — this guide is an AI-generated overview, not legal advice.
