The Arbitration (Amendment) Act Reshapes Dispute Resolution in Malaysia

In brief: The Arbitration (Amendment) Act 2024 (Act A1737) came into force on 1 January 2026, modernising Malaysia's arbitration framework. Among its key changes, it introduces a statutory basis for third-party funding, tightens the time windows for challenging and setting aside arbitral awards, and formally recognises the new AIAC Court of Arbitration.

This article is general information about Malaysian arbitration law for the public.

What is arbitration?

Arbitration is a private alternative to going to court: parties to a dispute agree to have it decided by one or more neutral arbitrators, whose decision (the 'award') is binding and enforceable. It is widely used in commercial and construction contracts because it can be faster, more confidential and more flexible than litigation, and awards are enforceable across borders under international treaties. The Asian International Arbitration Centre (AIAC), based in Kuala Lumpur, is Malaysia's flagship arbitral institution and competes with centres like Singapore and Hong Kong for regional work.

What is changing?

'Third-party funding' — where an outside financier pays a party's legal costs in exchange for a share of any award — was previously legally uncertain in Malaysia; giving it a statutory footing can widen access to justice for parties who could not otherwise afford a claim, while raising new questions about disclosure and control. Tightening the challenge and set-aside windows promotes finality, meaning awards are harder to drag out through prolonged court challenges — attractive to businesses that value certainty.

Why does it matter?

These reforms are designed to make Malaysia a more competitive seat for international arbitration and to align it with global best practice. For commercial lawyers and their clients, they change how disputes are funded, how quickly awards become final, and how the AIAC operates. If your contracts use arbitration clauses, it is worth reviewing them against the new framework.

What happens next?

The things to watch are how the courts interpret the new third-party funding provisions, whether the reforms attract more regional arbitration work to Kuala Lumpur, and the updated AIAC procedural rules.

Frequently asked questions

What is arbitration?

It is a private way of resolving disputes in which neutral arbitrators, rather than a court, decide the matter. Their decision (the award) is binding and can be enforced, including across borders.

What is third-party funding?

It is an arrangement where an outside financier covers a party's legal costs in return for a share of any award. The Arbitration (Amendment) Act 2024 gives it a clear statutory basis in Malaysia.

What should businesses do?

Review your arbitration clauses and dispute-resolution strategy against the new framework, particularly the tighter timelines for challenging awards and the option of third-party funding.
