One Country, Multiple Court Systems: A Practitioner's Guide to the UAE Judiciary in 2026, and How It Compares with the World's Major Federations

Ask a newly arrived general counsel to sketch the UAE court system on a whiteboard and the result is often a puzzled pause. Seven Emirates, a federal judiciary, four local judicial authorities, two English-language common-law court systems and specialist civil-family routes for non-Muslims can sound unwieldy on paper. In practice, it is a deliberately constructed legal architecture, and the reforms of the past four years have changed it materially from the version still found in many textbooks.

This article outlines the UAE judicial structure as it stands in 2026, then places it beside four federations that businesses in the UAE regularly encounter: the United States, Australia, Canada and India. Each has had to decide how judicial power should be distributed between the centre and its constituent parts. Their choices are markedly different.

The Constitutional Starting Point: Who Gets to Legislate

The UAE is a federation of seven Emirates: Abu Dhabi, Dubai, Sharjah, Ajman, Fujairah, Umm Al Quwain and Ras Al Khaimah. Its Constitution does not use a single provision to allocate all legislative power. Articles 120 and 121 identify matters within the Union's exclusive legislative competence. Articles 116 and 122 preserve Emirate competence in matters not exclusively entrusted to the federal authorities. Under Article 151, valid federal legislation prevails over conflicting Emirate legislation.

The UAE's onshore legal system is primarily civil law, influenced by French and Egyptian codification, while Sharia principles retain an important role in personal-status matters. Yet that description no longer captures the whole picture. The country now has a federal civil-law court system, four separate local judicial authorities, a statutory civil-personal-status route for non-Muslims and two financial free-zone court systems that operate in English and draw substantially on common-law methods.

The comparison with other federations is useful. Australia preserves State powers under section 107 of the Australian Constitution, while the Tenth Amendment reserves undelegated powers to the States in the United States. Canada and India take the opposite direction. Canada's Parliament has residual authority under the peace, order and good government power in section 91 of the Constitution Act, 1867, and Article 248 of the Indian Constitution gives Parliament exclusive power over residuary subjects. The constitutional allocation of power helps explain why the court structures differ so markedly.

The UAE Federal Court System

The Constitution permits a differentiated judicial structure. Under Article 104, local judicial authorities have jurisdiction in matters not assigned to the UAE courts. Article 105 allows all or part of that local jurisdiction to be transferred to federal Courts of First Instance by a federal law issued at the request of the relevant Emirate. In the federal system, cases generally proceed through Courts of First Instance and Courts of Appeal to the Federal Supreme Court in Abu Dhabi. The Federal Supreme Court exercises cassation jurisdiction, but its constitutional remit is broader. Article 99 also gives it original jurisdiction in specified constitutional, inter-governmental and federal matters. Its judges are appointed by Presidential Decree after ratification by the Federal Supreme Council.

The statutory foundations of the federal judiciary were comprehensively recast in 2022. Federal Decree-Law No. 32 of 2022 On the Federal Judicial Authority replaced the principal earlier federal judicial-authority legislation. Federal Decree-Law No. 33 of 2022 Concerning the Supreme Federal Court replaced the 1973 Supreme Court law. Federal Decree-Law No. 42 of 2022 Promulgating the Civil Procedure Code replaced the 1992 Civil Procedure Law. Together, these instruments modernised the institutional and procedural framework for federal litigation.

Federal Decree-Law No. 22 of 2025, effective from 1 January 2026, amended selected provisions of the Civil Procedure Code. The amendments include Article 32 on specialised judicial circuits, Article 164 on certain appeal procedures, Article 175 on cassation and Article 176 on cassation in the interests of law. In practice, the changes matter most in the treatment of specialised disputes, the conditions for cassation in qualifying cases, and the Attorney General’s exceptional Article 176 power to challenge, by cassation, qualifying final judgments and decisions within the statutory. The correct appellate route and deadline should therefore be analysed from the outset of a dispute.

The Local Judiciaries: Now Four, Not Three

For many years, the standard description was that Abu Dhabi, Dubai and Ras Al Khaimah maintained independent local court systems, while the other Emirates participated in the federal system. That description is no longer complete. Sharjah Law No. 7 of 2025 Concerning the Regulation of the Judicial Authority in the Emirate of Sharjah, effective from 1 June 2025, formalised Sharjah's separate judicial authority, including its own courts, public prosecution and Court of Cassation.

Within the onshore federal and local judiciary, the UAE has five top-level appellate courts operating in parallel: the Federal Supreme Court, and the Courts of Cassation of Abu Dhabi, Dubai, Ras Al Khaimah and Sharjah. The local systems broadly follow a first-instance, appeal and cassation model, but their jurisdiction and procedural administration remain separate from the federal cassation structure. Ajman, Fujairah and Umm Al Quwain continue within the federal court system. Both federal and local courts apply federal legislation and, where applicable, Emirate-level laws and regulations.

Counting the financial free-zone courts, the UAE can usefully be understood as operating seven judicial systems: the federal courts, the local judiciaries of Abu Dhabi, Dubai, Ras Al Khaimah and Sharjah, the DIFC Courts and the ADGM Courts. This is a practical description, not a statement that each system is wholly insulated from the others. Enforcement arrangements, jurisdictional rules and federal legislation create important points of interaction.

Personal Status: Two Statutory Routes, Both Recently Rewritten

The UAE's personal-status landscape has changed significantly in recent years. The Civil Personal Status Law, Federal Decree-Law No. 41 of 2022 On the Civil Personal Status, came into effect on 1 February 2023. It establishes a civil statutory route for non-Muslim UAE nationals and non-Muslim foreign residents, subject to the law's own scope and choice-of-law provisions.

The 2022 law provides for civil marriage, no-fault divorce and joint custody. Its inheritance rules are more nuanced than a simple formula of equal distribution. They apply in the absence of a valid will and are subject to the statute's provisions on applicable law and related elections. Forum, nationality, residence, an existing will and the relationship between the federal law and any applicable Emirate framework must all be assessed in the individual case.

Federal Decree-Law No. 41 of 2024 On the Issuance of the Personal Status Law came into force on 15 April 2025 and replaced Federal Law No. 28 of 2005. It is not accurately described as applying only to Muslims. Its scope provisions address UAE nationals and non-UAE nationals, subject to stated exceptions and the possible application of another law in particular circumstances. Where the statute is silent, Article 1 refers first to the provisions of Islamic Sharia and then, where appropriate, to custom that does not conflict with Sharia, public order or public morals. The law also generally extends custody to the age of 18.

The practical lesson is that family and inheritance disputes require early attention to the relevant statutory route, forum, nationality and any valid election of law. General labels such as 'Muslim system' and 'non-Muslim system' are often too blunt for cross-border matters.

The DIFC and ADGM Courts: Common Law Inside a Civil-Law Country

The DIFC Courts

The Dubai International Financial Centre Courts operate in English and apply DIFC legislation, with a substantial common-law orientation and their own developing case law. They comprise a Court of Appeal, Courts of First Instance and a Small Claims Tribunal. Their jurisdiction includes DIFC-connected disputes and, where the statutory conditions are met, cases in which parties have opted into DIFC Courts jurisdiction by agreement.

Dubai Law No. 2 of 2025 Concerning Dubai International Financial Centre Courts is now the principal Dubai-law framework. Article 14 permits written opt-in jurisdiction agreements but requires them to be specific, clear and express. Article 13 establishes the DIFC Courts' Mediation Centre, while Article 30 addresses the enforceability of approved mediation settlements. Article 32 sets out the framework for execution of DIFC Court writs through the Dubai Courts and limits reconsideration of the merits to what is necessary for enforcement procedure.

Recent enforcement decisions require careful treatment. ENF 185/2025 concerned an application involving a Dubai Court of First Instance judgment, not a foreign judgment. The restrictive first-instance enforcement orders in that sequence were set aside by the DIFC Court of Appeal in Orlagh v Orchid [2026] DIFC CA 001. ENF 271/2025 is a separate Court of First Instance decision involving English financial orders. These authorities are fact-specific. They should not be reduced to a general proposition that every foreign or onshore judgment can use the DIFC as an enforcement gateway without regard to statutory jurisdiction, asset location and parallel proceedings.

In practical terms, execution of a final DIFC judgment through the Dubai Courts involves the statutory execution documentation, the required Arabic translation and the applicable execution procedure. The enforcing judge does not undertake a substantive re-hearing of the underlying dispute.

The ADGM Courts

Abu Dhabi Global Market was established under Abu Dhabi Law No. 4 of 2013. Its courts operate within a free-zone framework that directly applies English common law, including principles of equity, through the Application of English Law Regulations 2015, subject to ADGM legislation. The ADGM Courts have a Court of First Instance and a Court of Appeal and hear civil and commercial disputes falling within their statutory jurisdiction, including disputes referred to them under a valid written opt-in arrangement.

The ADGM framework has a distinct enforcement architecture. Article 13 of the ADGM Founding Law addresses the relationship between ADGM Courts judgments and the Abu Dhabi courts. Article 13(14) contains an express limitation relevant to judgments or orders that recognise or enforce a judgment, order or award originating outside Abu Dhabi. The ADGM Courts have also entered into memoranda of understanding with the Abu Dhabi Judicial Department, Ras Al Khaimah Courts, the UAE Ministry of Justice and, from 14 January 2025, Dubai Courts. The detail and legal effect of each arrangement should be checked against the relevant memorandum and the current enforcement rules before a creditor commits to a route.

How the Other Federations Do It

United States: Full Dual Sovereignty

The United States has federal and State court systems operating in parallel. Article III of the United States Constitution establishes the federal judicial power, with the Supreme Court at the apex and lower federal courts created by Congress. State courts retain broad authority over State-law disputes, subject to the supremacy of federal law under Article VI, Clause 2. The result is a mature dual-sovereignty model in which jurisdictional questions are an ordinary feature of litigation.

Australia: Parallel Courts with a Constitutional Link

Australia is a federation of six States and two self-governing mainland territories. Section 71 of the Constitution creates the federal judicial-power framework, while section 77(iii) permits Parliament to invest State courts with federal jurisdiction. This enables State courts to perform an important role in the administration of federal law.

The federal family-court structure was reconfigured in 2021, when the Federal Circuit Court and the Family Court were brought together as the Federal Circuit and Family Court of Australia. Division 1 deals principally with complex family-law matters and appeals, while Division 2 is the entry point for a broader range of family, migration and federal matters. The High Court remains the ultimate appellate court.

Canada: Bijural, with Shared Institutional Responsibility

Canada has ten provinces and three territories and a bijural legal order. Common law applies generally, while Quebec's private law is civil law. Section 92(14) of the Constitution Act, 1867 gives provinces responsibility for the administration of justice in the province. At the same time, section 96 gives the federal government responsibility for appointing judges of provincial superior courts. Security of tenure and salaries for federally appointed judges are addressed in sections 99 and 100.

The federal judicial structure includes the Federal Court, the Federal Court of Appeal, the Tax Court of Canada and the Supreme Court of Canada. The Supreme Court Act requires that at least three of the nine Supreme Court judges come from Quebec. The structure is neither wholly centralised nor wholly provincial. It combines provincial court administration with federal appointments at the superior-court level.

India: One Integrated Judiciary for an Entire Union

India is a Union of twenty-eight States and eight Union Territories. Article 246 divides legislative competence between the Union, State and Concurrent Lists, while Article 248 gives Parliament residuary legislative power. Despite this legislative division, India has a single integrated judiciary. The Supreme Court of India is at the apex, and Article 141 makes its declared law binding on all courts in the country.

Below the Supreme Court, High Courts serve individual States or groups of States, with subordinate courts beneath them. There is no separate federal-court hierarchy comparable to that of the United States or Australia. For a lawyer accustomed to the UAE's multiple parallel systems, India is striking for the unity of its judicial hierarchy.

The Five Systems at a Glance

Why This Matters in Practice

The comparison is not academic. The UAE court structure affects three recurring decisions for businesses. The first is forum selection at the contract stage. Depending on the parties, the transaction and the subject matter, a Dubai-connected arrangement may provide for onshore Dubai Courts, DIFC Courts, ADGM Courts or arbitration. A purported opt-in to the DIFC Courts must satisfy the written, specific, clear and express requirements in Dubai Law No. 2 of 2025.

The second is enforcement strategy. A judgment creditor must consider the origin of the judgment, the debtor's assets, whether relevant proceedings are already underway and the statutory or memorandum-based route available to the enforcing court. The DIFC and ADGM should not be treated as automatic alternatives to direct onshore enforcement. Each route has its own jurisdictional conditions.

The third is procedural planning. The Civil Procedure Code amendments effective from January 2026 show that appellate rights, filing formalities and specialised judicial routes need to be addressed at an early stage. A technical point that looks procedural can determine whether a substantive case is ever heard on appeal.

Step back and the design logic of the UAE system becomes clearer. The United States and Australia operate mature forms of federal and State judicial interaction. Canada separates aspects of court administration and appointment. India operates an integrated judicial hierarchy. The UAE has chosen a different solution. It allows Emirates to maintain or transfer judicial jurisdiction within a constitutional framework, accommodates specialist personal-status routes, and supports two English-language financial free-zone courts. For a country that combines a federal civil-law tradition with global commercial ambitions, that plurality is a central feature rather than an anomaly.
