Since 1 January 2026, construction payment disputes in Malaysia run under an amended CIPAA. The Construction Industry Payment and Adjudication (Amendment) Act (Act A1738), passed by Parliament in 2024, came into operation on that date together with the CIPAA (Amendment) Regulations 2025. For unpaid contractors and subcontractors, the headline is simple: the statutory adjudication route just became a sharper weapon.
The amendments pull in one consistent direction — faster decisions, tighter procedural discipline, clearer boundaries on what can be claimed, and a stronger bridge from an adjudication decision to actual money in the bank. Here is what changed, and what it means in practice.
The changes at a glance
| Area | Before 2026 | From 1 January 2026 |
|---|---|---|
| Decision timeline | 45 working days from the adjudication response/reply, with extensions in practice stretching matters | Tighter overall clock — decisions must be delivered on a compressed timeline with stricter limits on extensions |
| Enforcement | Application to the High Court to enforce the decision as a judgment; pace varied | Strengthened route through the High Court's construction division, converting decisions into enforceable judgments faster |
| Scope of claims | "Payment under a construction contract" — boundary disputes common | Clarified: progress payments, final payments and retention sums are in; damages and loss-of-profit claims are out |
| Subcontractor protection | Direct payment from the principal available under the Act | Direct-payment mechanism reinforced |
| Institution | Statutory references still to the former KLRCA | All references formally updated to the Asian International Arbitration Centre (AIAC) |
Faster adjudication, less room to stall
The economics of construction late payment have always favoured the paying party: every month of delay is free financing extracted from the contractor below. The amendment attacks that directly by compressing the adjudication timetable and restricting the extension mechanics that respondents previously used to buy time. Commentary on the amendments reports a requirement for decisions within 45 working days of the adjudicator's appointment, with tighter rules on extensions — the precise operation of the new clock should be confirmed against the Act and the AIAC's current practice for your matter, but the direction is unambiguous: shorter, stricter, less elastic.
For claimants, a compressed timetable rewards preparation. The party that arrives with a complete, well-documented claim gains the most from a fast clock; the party that plans to develop its case as it goes loses that luxury.
A clearer boundary on what you can claim
The amendments clarified the scope of "construction contract" payments that adjudication can reach:
- Inside the regime: progress payments, final payments and retention sums — the certified and uncertified amounts due for work done and materials supplied under the contract.
- Outside the regime: damages and loss-of-profit claims, which belong in arbitration or court, not statutory adjudication.
This matters for how you draft a payment claim. Loading a claim with heads that sit outside the statutory scope invites jurisdictional challenge and delay — exactly what the fast-track regime exists to avoid. Retention sums, long a battleground, are now clearly within reach; our guide on recovering retention sums and unpaid progress claims covers the tactics in detail.
Stronger enforcement: from decision to judgment to money
An adjudication decision was always binding under section 13 unless set aside, settled or superseded — but binding on paper is not the same as paid. The 2026 amendments strengthen the enforcement bridge through the High Court's construction division, allowing successful claimants to convert adjudication decisions into judgments more quickly. Once converted, the full enforcement arsenal opens up: garnishee proceedings against the respondent's bank accounts and receivables, writs of seizure and sale, and — where the respondent is a company and the judgment debt qualifies — the section 466 statutory demand and winding-up route.
In other words, the amendments shorten the distance between "the adjudicator says you are owed RM 800,000" and a frozen bank account concentrating the respondent's mind.
Direct payment for subcontractors, reinforced
CIPAA's direct-payment mechanism — the ability of an unpaid party holding an adjudication decision to require payment directly from the principal further up the chain, out of money the principal owes the defaulting party — was reinforced by the amendments. For subcontractors, this remains one of the most underused levers in the Act: it lets you bypass an insolvent or obstinate main contractor and collect from the employer's side of the ledger. The mechanics of running a claim from payment claim through to direct payment are set out step by step in our companion guide, how to make a CIPAA payment claim as a subcontractor.
KLRCA is finally, formally, AIAC
A housekeeping change with practical relevance: all statutory references to the former Kuala Lumpur Regional Centre for Arbitration (KLRCA) have been replaced with the Asian International Arbitration Centre (AIAC) — the body that has in practice administered CIPAA adjudications since the 2018 rebrand. Appointment of adjudicators, registration of adjudications and the applicable forms and fee schedules all run through the AIAC under the 2025 Regulations.
Where a published summary and the statute could diverge — as with the exact operation of the new decision deadline and extension rules — anchor your position on the Act and the AIAC's current circulars, not secondary commentary. The direction of the 2026 changes is settled; the fine mechanics of the clock are exactly the kind of detail a respondent will exploit if your notice or timeline calculation is a day out. Diarise every CIPAA deadline from the statutory trigger date, in working days, and verify against the AIAC's calendar.
What contractors and subcontractors should do now
- Re-baseline your credit control on the new clock. If adjudication now moves faster end-to-end, the optimal moment to escalate an unpaid progress claim moves earlier too. Sitting on a 90-day-overdue certificate is more expensive than it was in 2025.
- Audit your paper trail per claim head. Progress claims, final accounts and retention releases are in scope; keep them cleanly separated from any damages narrative so the adjudicator's jurisdiction is never in doubt.
- Treat the adjudication decision as the midpoint, not the finish. Plan the enforcement step — High Court conversion, then garnishee or statutory demand — before the decision lands.
- Subcontractors: map the payment chain above you. Knowing who the principal is, and what it owes your defaulting employer, is the groundwork for a direct-payment demand.

Frequently asked questions
When did the CIPAA amendments come into force?
1 January 2026. The Construction Industry Payment and Adjudication (Amendment) Act (Act A1738), passed by Parliament in 2024, came into operation on 1 January 2026 together with the CIPAA (Amendment) Regulations 2025.
What are the main changes in the 2026 CIPAA amendments?
Tighter adjudication timelines with stricter extension rules, strengthened enforcement of adjudication decisions through the High Court's construction division, a clarified scope of claimable amounts (progress payments, final payments and retention sums in; damages and loss of profit out), reinforced direct-payment protection for subcontractors, and formal replacement of KLRCA references with the AIAC.
Can I still claim damages or loss of profit under CIPAA?
No. The amendments clarified that CIPAA adjudication covers payments due under the construction contract — progress claims, final payments and retention sums. Claims for damages or loss of profit fall outside the statutory adjudication scope and must be pursued through arbitration or the courts.
Do the amendments apply to payment claims already running before 2026?
Transitional treatment depends on when the adjudication was commenced, and the position for in-flight matters should be checked against the Act and the 2025 Regulations before relying on either regime. For claims commenced from 1 January 2026, the amended framework applies.
