The commercial consequences of overlooking this change are real. A contract drafted under the previous civil law framework now falls to be interpreted, enforced, and disputed under a different set of rules. Pre-contractual conduct attracts greater judicial scrutiny. Good faith obligations have been recalibrated. Limitation periods have changed. None of this is prospective. It applies to agreements already signed.

We advise clients to treat 1 June 2026 as the operative date for all contract review decisions. Any subsequent guidance from courts or arbitral institutions should be treated as clarification, not as relief from the obligation to act now.

The Legislative Framework

Federal Decree-Law No. 25 of 2025 replaces the previous civil transactions regime and introduces three substantive changes with immediate commercial relevance:\

1. Contractual interpretation is now governed by a more structured judicial framework. Courts will examine pre-contractual conduct, including negotiation records, term sheets, and correspondence, as part of the interpretive exercise.
2. Good faith obligations have been elevated. Parties now carry a more explicit duty of good faith across the full contracting lifecycle, from negotiation through performance and termination.
3. Limitation periods and remedy proportionality have been amended. Contracts built around specific limitation strategies may no longer operate as originally intended.

The jurisdictional reach of this law is comprehensive. It applies to all commercial contracts governed by UAE law, regardless of the nationality or incorporation status of the parties. Entities within the DIFC and ADGM are not exempt where their contracts reference UAE federal civil law.

Key Obligations for Commercial Parties

The immediate obligations fall into four categories:

1. Contract audit. Every active commercial agreement governed by UAE law must be reviewed against the changed interpretation, good faith, and limitation provisions. Priority should be given to contracts containing termination triggers, liability caps, force majeure clauses, and dispute resolution mechanisms.
2. Template review. Standard form agreements and boilerplate terms drafted before 2025 were calibrated to the previous civil law framework. They require updating before being used in new transactions.
3. Pre-contractual record management. Negotiation correspondence, heads of terms, and letters of intent now carry greater interpretive weight before UAE courts and tribunals. Internal records must be managed with this in mind going forward.
4. Arbitration clause reassessment. The new CTL interacts directly with the amended Civil Procedure Code, also effective in 2026. Seat selection, institutional rules, and enforcement pathways carry different consequences under the combined effect of both instruments.

Emerging Risks in Practice

Three patterns of exposure are already visible across the market:

1. Outdated template reliance. Many businesses continue to use standard contracts drafted before 2025 without recognising that the default rules those templates assumed have now changed. The contract may be valid. The assumptions embedded in it may not be.
2. Misapprehension of scope. There is a common belief that changes to civil transactions law affect only large commercial disputes or formally litigated matters. In reality, the new rules govern how every UAE-law contract is read at every stage, including during renegotiation, variation requests, and pre-dispute correspondence.
3. Arbitration clause drift. The 2024 Dubai Court of Cassation ruling invalidating asymmetric jurisdiction clauses, combined with the new CTL and civil procedure amendments, means that dispute resolution clauses drafted even two or three years ago may now carry enforceability risk that did not exist when they were signed.

Commercial and Transactional Implications

Beyond the direct impact on existing contracts, the new CTL has immediate consequences for ongoing and planned transactions.

In M&A and joint venture due diligence, the governing law and dispute resolution provisions of target company contracts are now a more material review item than before. A counterparty whose template agreements were drafted under pre-2026 assumptions represents a contractual risk that needs to be priced and managed.

In financing transactions, lenders and borrowers alike should confirm that facility agreements, security documents, and intercreditor arrangements have been reviewed against the changed limitation and remedy provisions. A clause that was conservative under the old framework may read differently under the new one.

Recommended Action Items

1. Contract audit. Identify all active agreements governed by UAE law and assess them against the changed interpretation, good faith, and limitation framework.
2. Template update. Review and revise standard form agreements before deploying them in new transactions. Do not assume that previous drafts remain fit for purpose.
3. Pre-contractual hygiene. Ensure that negotiation records are consistent with final signed positions. Inconsistency between the two is now a larger litigation exposure than it was before 1 June 2026.
4. Dispute resolution review. Assess whether existing arbitration clauses and governing law selections remain strategically appropriate under the combined effect of the new CTL and civil procedure amendments.
5. Proactive counsel engagement. The new CTL rewards parties who have documented good faith conduct throughout the contracting process. That documentation discipline needs to begin now, not at the point of dispute.

Conclusion

The new Civil Transactions Law does not give businesses a portal to register on or a deadline to file by. That is precisely what makes it easy to overlook and difficult to recover from. The rules governing how your contracts are read and enforced changed on 1 June 2026. Those who have not yet reviewed their commercial documentation in light of this change are operating on assumptions that are no longer supported by law.
