How do you challenge an arbitral award in the UAE courts?

Where an onshore challenge is filed and when

Under Article 54(2) of Federal Law No. 6 of 2018, an action to annul an award must be brought within 30 days. The period starts on the date the award was notified to the party seeking annulment. Article 1 defines the Court for this purpose as the federal or local Court of Appeal. The action starts one level above an ordinary civil claim. Our arbitration lawyers in the UAE act for award creditors and award debtors on annulment, recognition and enforcement.

The timing depends on notification rather than on the date of the award. Article 44 requires the tribunal to notify each party within 15 days of issuing the award, by delivering a signed original or copy.

Article 53(1) allows only two ways to object to an award. The first is a standalone action in nullity. The second is a defence raised while the court examines the winning party's request for recognition. The second route has no equivalent time limit, because there is no deadline for applying to recognise an award. A party that misses the 30 days keeps its grounds, but loses the ability to move first.

Federal Decree-Law No. 15 of 2023 amended Articles 10, 23, 28 and 33 of the Arbitration Law and added Article 10 bis. It left the annulment provisions untouched, so Articles 53 to 57 apply as enacted in 2018.

The grounds a challenger must prove

Article 53(1) lists eight grounds, and the party seeking annulment carries the burden of proving one of them.

• No arbitration agreement existed, or it was void or had lapsed under the chosen law.
• A party lacked capacity when the arbitration agreement was concluded.
• A party had no legal capacity to act in the disputed right, as Article 4 requires.
• A party could not present its defence, through defective notice or through the tribunal's failure to observe the principles of litigation.
• The award did not apply the law the parties agreed would govern the subject matter.
• The tribunal was constituted, or an arbitrator appointed, contrary to the law or the parties' agreement.
• The proceedings were void in a way that influenced the award, or the award was issued after its time limit expired.
• The award decided matters outside the arbitration agreement, in which case only the excess is annulled where it can be separated.

The third ground concerns signing authority. Article 4(1) allows an arbitration agreement to be concluded only by a person with capacity to act. A company must act through a representative authorised to conclude it, and the agreement is void otherwise. A signature on a supply contract does not carry that authority by itself. Clause drafting and signing authority are covered in our guide to choosing a UAE arbitration clause.

The two grounds the court applies without being asked

Article 53(2) requires the Court to annul the award on its own initiative on two further grounds. The first is that the subject matter cannot be settled by arbitration. The second is that the award conflicts with the public order and public morality of the State.

Neither ground needs to be pleaded. Both remain available to the court examining a recognition request, so a strong award can still fail at the enforcement stage on a point nobody argued.

What the court will not reconsider

In Cassation No. 1115 of 2024, decided on 25 November 2024, the Dubai Court of Cassation addressed the scope of an annulment claim. It confirmed that the claim does not open the merits of the dispute to the court. The court does not review whether the tribunal applied the governing law correctly. Assessing and admitting evidence remains within the tribunal's sole discretion.

In Cassation No. 864 of 2024, decided on 12 November 2024, the same court addressed multi-tiered clauses. A failure to observe pre-arbitration steps does not give jurisdiction to the domestic court. Whether a claim was filed prematurely is a question for the tribunal.

Form defects have narrowed as well. In 2025 the Federal and Local Judicial Principles Unification Authority confirmed that arbitrators need only sign the final page of an award. That resolved conflicting judicial positions and closed a ground which had produced years of challenges.

Article 54(6) narrows the remaining formal arguments further. The Court may stay the annulment proceedings for up to 60 days so the tribunal can correct a defect in the form of the award. The correction must not affect the contents.

How the DIFC route differs

A DIFC-seated award follows DIFC Law No. 1 of 2008 rather than the federal law. Article 41 makes an application to set aside the only recourse against the award, and that application goes to the DIFC Courts.

On 24 April 2026 the DIFC Court of Appeal decided Oheo Bank v Parker. It is understood to be the first occasion on which the DIFC Courts have set aside a DIFC-seated award. The tribunal had upheld a claim that crystallised only in a post-hearing brief, without inviting the respondent to answer it. The Court placed its decision on a narrow and fact-specific basis. It distinguished protection from injustice from protection against the consequences of a party's own choices.

Whether enforcement continues while the challenge is pending

Article 56(1) states that filing an action in nullity does not stay enforcement of the award. The Court examining the nullity action may order a stay at a party's request, but only where the request is based on serious grounds.

Article 56(2) requires the Court to decide the stay request within 15 days of the first hearing fixed to examine it. Under Article 56(3) the Court may order the applicant to provide a financial guarantee or security. Once it grants a stay, it must decide the nullity action within 60 days.

The enforcement side moves on its own timetable. Article 55 requires the president of the Court to order recognition and enforcement within 60 days of the request. The exception is where grounds under Article 53(1) are proven. Article 57 then allows a grievance against a decision ordering or refusing enforcement, filed with the competent appeal court within 30 days of notification.

Once an award is recognised it enters the execution system that applies to court judgments, described in our article on enforcing a UAE court judgment. Where the seat was the DIFC, the onward route to mainland assets is covered in our article on enforcing a DIFC judgment in mainland Dubai.

What to do in the first 30 days

• Record the date and method of notification, because the period starts from notification rather than from the award.
• Identify the seat in the arbitration clause, since it decides whether the federal law or the DIFC law applies.
• Obtain the signing authority documents for the arbitration agreement, because Article 53(1)(c) turns on them.
• Decide between filing an action and holding the grounds as a defence to recognition, because only one of those carries a deadline.
• Where a stay of enforcement is needed, prepare the security, since the Court may require it as a condition.

An award creditor should move in parallel. A precautionary attachment can be obtained on the basis of an award before ratification, under Federal Decree-Law No. 42 of 2022. Our article on contractor payment security in the UAE describes that route.

Is an annulment action the right move, or a defence to enforcement?

The two routes carry the same grounds and different risks. An action in nullity puts the award debtor on the front foot and preserves the choice of when to argue. The cost is a 30 day window and the expense of leading the case. Holding the grounds as a defence costs nothing until the creditor applies. It leaves the timing to the other side, and Article 56 means enforcement may proceed meanwhile.

Legal advice may be required to assess which route fits a particular award, its seat, and the assets the creditor is pursuing.
