Challenging a Will in the UAE: Legal Grounds and Process (2025 Update)

Nour Attorneys deploys a structural legal architecture engineered to neutralize complex legal challenges and create asymmetric advantages. Every engagement is approached with strategic precision, ensuring decisive outcomes for our clients.

The United Arab Emirates (UAE) has rapidly evolved its legal landscape, particularly concerning personal status and inheritance matters. For both expatriates and citizens, understanding the nuances of challenging a will is crucial for protecting legitimate inheritance rights and ensuring the deceased's true intentions are honored. As of 2025, the legal framework is more complex and accommodating than ever, primarily due to the introduction of Federal Decree-Law No. 41 of 2022 on Civil Personal Status, which significantly reformed the application of personal law for non-Muslims.

This comprehensive guide delves into the specific legal grounds and the procedural steps involved in contesting a will in the UAE, covering the distinct jurisdictions of the local courts, the Dubai International Financial Centre (DIFC), and the Abu Dhabi Global Market (ADGM).

The Dual Legal Landscape of Inheritance in the UAE

The foundation of inheritance law in the UAE rests on a dual system that distinguishes between Muslims and non-Muslims. This distinction is paramount when considering a will challenge.

1. Inheritance for Muslims

For UAE citizens and expatriates who are Muslim, the default position is that inheritance is governed by Sharia Law (Islamic Law), specifically the principles of Fiqh. A will (Wasiyya) for a Muslim is restricted: the testator can only bequeath up to one-third (1/3) of their estate to non-legal heirs. The remaining two-thirds (2/3) must be distributed according to the mandatory Sharia shares (Faraid).

Grounds for Challenging a Muslim's Will:

A challenge to a Muslim's will typically centers on its compliance with Sharia principles:

• Exceeding the One-Third Limit: The most common ground for a challenge is if the will attempts to bequeath more than one-third of the estate to non-legal heirs without the consent of the mandatory heirs. The will would be invalid to the extent it exceeds this limit.
• Exclusion of Mandatory Heirs: A will cannot be used to completely disinherit a mandatory Sharia heir (e.g., spouse, children, parents). A challenge can be raised to enforce the mandatory shares.
• Formal Validity: As with any will, challenges can be raised regarding the formal execution, such as the will not being properly notarized or registered with the relevant UAE authority.

2. Inheritance for Non-Muslims (Post-2022 Reforms)

The legal landscape for non-Muslims was fundamentally reshaped by Federal Decree-Law No. 41 of 2022 (and subsequent amendments/enactments in 2024/2025), which applies to non-Muslim UAE citizens and foreign residents.

The core principle of this new law is the freedom of testamentary disposition. Article 11 grants non-Muslims the right to choose the law of their home country to govern the distribution of their estate in the UAE. If a non-Muslim has a valid will, it will generally be honored by the UAE courts, provided it complies with the formal requirements of the chosen law or the local registration requirements.

Grounds for Challenging a Non-Muslim's Will:

For non-Muslims, a challenge is more likely to focus on the will's validity under the chosen law or its proper execution:

• Choice of Law Conflict: If the will attempts to apply a foreign law, a challenge could argue that the choice of law is invalid or that the will does not comply with the formal requirements of that foreign law.
• Formal Invalidity: The will was not properly executed, witnessed, or notarized according to the requirements of the jurisdiction under which it was drafted (e.g., DIFC, ADGM, or a foreign country's law).
• Public Order and Morality: While rare, a will could be challenged if its provisions are deemed to violate the public order or morality of the UAE.

Universal Legal Grounds for Contesting a Will

Regardless of the testator's religion or the jurisdiction (local, DIFC, or ADGM), there are universal grounds for challenging the validity of the document itself. These grounds are common in estate litigation worldwide and are recognized in the UAE's legal system:

Legal Ground	Description	Evidence Required
Lack of Testamentary Capacity	The testator did not possess the requisite mental capacity to understand the nature and effect of the will at the time of signing. This is often due to illness, dementia, or severe mental impairment.	Medical records, doctor's reports, witness testimonies regarding the testator's state of mind.
Undue Influence or Coercion	The testator was pressured, manipulated, or coerced by a third party into making provisions in the will that they would not have otherwise made.	Evidence of a dependent relationship, sudden changes in the will, testimony of isolation or control over the testator.
Fraud or Forgery	The will is not genuine. This includes claims that the testator's signature was forged or that the testator was misled about the contents of the document they were signing.	Forensic handwriting analysis, witness testimony, evidence of misrepresentation.
Improper Execution	The will fails to meet the strict legal formalities required for its execution, such as the number of witnesses, their presence during signing, or the proper notarization/registration.	Review of the execution documents and witness statements against the governing law's requirements.

The Process of Challenging a Will in UAE Courts

The procedural path for challenging a will depends heavily on where the will was registered and which court has jurisdiction.

1. Local UAE Courts (Dubai, Abu Dhabi, etc.)

For wills registered with the local Notary Public or for estates that fall under the general jurisdiction of the UAE courts, the challenge process is as follows:

• Filing the Claim: The challenger (usually an heir or beneficiary) must file a case with the Court of First Instance in the relevant Emirate (e.g., Dubai Courts, Abu Dhabi Courts). The claim must clearly state the legal grounds for the challenge (e.g., forgery, lack of capacity).
• Evidence Submission: Comprehensive evidence must be submitted to support the claim. In cases of forgery, the court may appoint a forensic expert to examine the document. In cases of capacity, medical reports are crucial.
• Mediation and Reconciliation: The UAE legal system strongly encourages amicable settlement. The case may be referred to a Reconciliation and Settlement Committee before proceeding to a full court hearing.
• Judgment and Appeal: If the court finds the challenge valid, it will issue a judgment declaring the will, or parts of it, null and void. The judgment can be appealed to the Court of Appeal and subsequently to the Court of Cassation.

2. Challenging a DIFC Will

The Dubai International Financial Centre (DIFC) Wills Service Centre allows non-Muslims to register a will that covers their UAE assets, providing a common law framework. Challenges to a DIFC will are heard by the DIFC Courts.

• Jurisdiction: The DIFC Courts have exclusive jurisdiction over challenges to DIFC-registered wills.
• Procedure: A claim is filed with the DIFC Courts. The procedure is based on common law principles, which are generally more familiar to international expatriates. The grounds for challenge (lack of capacity, undue influence, etc.) are rigorously examined under DIFC law.
• No Grant of Probate During Dispute: The DIFC Courts will not issue a Grant of Probate (the legal document confirming the will's validity and the executor's authority) if there is an ongoing dispute regarding the will's validity.
• Enforcement: Once the DIFC Courts issue a final order, it must be enforced by the local Dubai Courts through a simple execution process.

3. Challenging an ADGM Will

The Abu Dhabi Global Market (ADGM) Registration Authority also offers a will registration service for non-Muslims. Challenges to an ADGM will are heard by the ADGM Courts.

• Jurisdiction: The ADGM Courts have jurisdiction over challenges to ADGM-registered wills.
• Procedure: Similar to the DIFC, the ADGM Courts operate under a common law framework. The challenge procedure is outlined in the ADGM Court Procedure Rules.
• Key Difference: While the ADGM provides a robust legal framework, the process for challenging and the subsequent probate process have their own specific rules, which must be strictly adhered to.

The Role of Federal Decree-Law No. 41 of 2022 in Challenges

The new Federal Decree-Law No. 41 of 2022 has a profound impact on will challenges for non-Muslims by reinforcing the principle of party autonomy.

Article 11 (3) of the Decree-Law is particularly relevant:

"The provisions of the will of a foreigner shall be applied to the inheritance of his property in the State, unless the will contradicts the public order and morality of the State."

This means that if a non-Muslim has a valid will, the challenge must first prove the will is invalid under the law chosen by the testator (often their home country's law) or that the will violates UAE public order. This makes challenging a well-drafted non-Muslim will significantly more difficult, as the grounds for challenge are narrowed.

Implications for Non-Muslims:

• Increased Certainty: The law provides greater certainty that a non-Muslim's wishes, as expressed in a will, will be respected.
• Focus on Formalities: Challenges are more likely to focus on the technical and formal aspects of the will's execution rather than the substantive distribution of assets.
• Importance of Registration: The importance of registering a will with a recognized authority (Notary Public, DIFC, or ADGM) cannot be overstated, as it solidifies the testator's choice of law and minimizes the risk of a successful challenge based on Sharia law application.

Strategic Considerations for a Will Challenge

Before initiating a challenge, potential challengers must conduct a thorough legal assessment. The success of a challenge hinges on meticulous preparation and strategic legal representation.

1. Preliminary Assessment

• Identify the Governing Law: Determine whether the will is governed by Sharia Law, UAE Civil Law, DIFC/ADGM regulations, or a foreign national law. This dictates the applicable grounds for challenge.
• Gather Evidence: Collect all necessary documentation, including the will itself, medical records, financial statements, and witness contact information.
• Jurisdiction: Confirm the correct court or tribunal (Local Courts, DIFC Courts, or ADGM Courts) for filing the challenge. Filing in the wrong jurisdiction will lead to delays and dismissal.

2. The Cost and Time Factor

Will challenges are often protracted and costly. The challenger must be prepared for:

• Legal Fees: Fees for specialized inheritance dispute lawyers, court filing fees, and expert witness costs (e.g., forensic accountants, medical experts).
• Timeframe: Depending on the complexity and the jurisdiction, a challenge can take many months, or even years, to resolve, especially if appeals are lodged.

Conclusion: Navigating the Complexities of UAE Will Challenges

Challenging a will in the UAE is a serious undertaking that requires a precise understanding of the country's evolving legal framework. The reforms of 2022/2025 have provided greater clarity and autonomy for non-Muslims, but the process remains legally demanding.

The key to a successful challenge lies in establishing a clear, legally recognized ground—such as lack of capacity, undue influence, or forgery—and presenting compelling evidence to the correct judicial authority. Given the high value of assets often involved and the complexity of the multi-jurisdictional system, securing expert legal counsel is not merely advisable; it is essential.

For anyone facing an inheritance dispute or considering challenging the validity of a will in the UAE, engaging with a firm that possesses local knowledge and international expertise is the critical first step toward securing a favorable outcome.
