Bilingual Contracts in the UAE: English vs Arabic Guide

When parties sign bilingual contracts in the UAE, the Arabic version prevails over the English version in any onshore court dispute, regardless of which language was used during negotiations. This rule catches many founders off guard, especially those who negotiated their deal entirely in English and assumed that version would control. Understanding when Arabic takes priority, when it does not, and how to structure your bilingual agreement correctly can save you from costly surprises down the line.

Does the UAE Require Bilingual Contracts?

No Mandatory Arabic Requirement for Private Commercial Contracts

Contrary to popular belief, UAE law does not require commercial contracts between private parties to be written in Arabic. Parties may freely draft contracts in English, and English-only contracts are routinely enforceable across the Emirates. As of 2026, there is no statute that voids a contract simply because it was written in a language other than Arabic.

When Arabic Becomes Mandatory

However, certain documents must be in Arabic or accompanied by a certified Arabic translation. These include:

• Memoranda of association filed with the Department of Economic Development (DED)
• Powers of attorney submitted to a notary public
• Share-transfer agreements requiring government registration
• Any contract, evidence, or legal notice filed in an onshore UAE court

For these categories, Arabic is mandatory either as the original language or as a certified translation appended to the foreign-language version. Consequently, founders planning to register documents with a government authority should budget for professional translation from the outset.

The Arabic-Prevails Rule in Onshore UAE Courts

How the Rule Works

In onshore (mainland) UAE contracts governed by UAE law, the Arabic version prevails if there is any discrepancy between the Arabic and English texts. UAE courts treat the Arabic text as the operative contract. This applies even if both parties negotiated exclusively in English and even if the English version was drafted first.

Because Arabic is the official language of UAE courts, judges rely on the Arabic text when interpreting contractual obligations. Therefore, any translation error or subtle difference between the two versions could change the outcome of a dispute.

Why This Catches Founders Off Guard

Many founders sign an English version first and commission the Arabic translation weeks later. This creates two problems. First, the Arabic translation may diverge from the English original in material ways. Second, the other party may argue that the terms were not truly agreed because the binding Arabic version did not exist at the time of signature.

In addition, some founders use uncertified translations to save money. An uncertified translation carries no official weight and may not be accepted by the court at all. If the court orders a fresh certified translation, the new version could differ from the one the parties relied on.

The Role of the MOJ-Licensed Translator

Under Federal Law No. 6 of 2012 (Regulating the Translation Profession) and its Executive Regulations under Cabinet Resolution No. 7 of 2014, only translators registered with the UAE Ministry of Justice and licensed by the relevant emirate-level authority may perform legal translation. Using anyone else for court-filed documents is not just risky; it may render the translation inadmissible. If you need a certified translation for contracts, court documents, or corporate papers, our Legal Translation UAE service covers exactly this requirement.

Bilingual Contracts in the UAE: Onshore vs DIFC vs ADGM

The jurisdiction clause in your contract is the upstream lever that determines which language rules apply. Below is a side-by-side comparison to help you understand the differences.

Factor	Onshore UAE (Mainland)	DIFC	ADGM
Legal system	Civil law (codified)	Common law	Common law
Language of court proceedings	Arabic	English	English
Contract language accepted	English or Arabic; Arabic prevails on conflict	English (Arabic optional)	English (Arabic optional)
Arabic translation needed for litigation?	Yes, by MOJ-licensed translator	No	No

DIFC: English as the Official Court Language

DIFC Courts operate under a common-law system with English as the official language of proceedings. Contracts litigated before the DIFC Courts can be in English only and do not require an Arabic translation. As a result, the Arabic-prevails default simply does not apply. For founders structuring cross-border deals or international joint ventures, DIFC jurisdiction removes the bilingual complexity entirely.

ADGM: English Common Law Applies Directly

Similarly, in the ADGM, the Application of English Law Regulations 2015 makes English common law directly applicable, except where overridden by ADGM’s own legislation. Contracts governed by ADGM law are interpreted in English under English common-law principles. This makes ADGM another strong option for founders who want to avoid the Arabic-prevails question altogether.

Watch Out for Jurisdiction Mismatches

One of the most common pitfalls is selecting DIFC or ADGM as the governing law but specifying onshore courts as the dispute forum, or vice versa. This mismatch creates confusion about which language rules apply and can delay enforcement significantly. Before signing, ensure your governing-law clause and jurisdiction clause align. If you are unsure which structure fits your situation, consider getting professional legal advice before execution.

Best Practices for Drafting Bilingual Contracts in the UAE

Include a Prevailing-Language Clause

Every bilingual contract intended for an onshore UAE setting should contain an explicit prevailing-language clause naming Arabic as the controlling version. While Arabic prevails by default in onshore courts, an explicit clause eliminates ambiguity and signals to judges that the parties understood and accepted this rule. A typical clause reads:

Hi. This Agreement is executed in Arabic and English. In the event of any discrepancy or conflict between the two versions, the Arabic version shall prevail.”

Notably, if both parties prefer English to control, they can achieve this by choosing DIFC or ADGM as the governing law and jurisdiction.

Commission Certified Translation Early

Do not treat translation as an afterthought. Commission a certified Arabic translation from an MOJ-licensed translator before, or at the same time as, finalising the English draft. This ensures both texts are reviewed together and reduces the risk of material divergence. Furthermore, having the certified Arabic text ready at signing strengthens your position if a dispute arises later.

Execute Both Versions Simultaneously

Best practice calls for signing both language versions on the same date, ideally as a single bound document. This prevents arguments about which version was actually agreed and ensures the Arabic text is treated as binding from day one rather than as a retroactive back-fill.

Review Corporate Documents Holistically

Bilingual contract issues often intersect with broader corporate structuring decisions. For example, your choice of jurisdiction affects not just language rules but also your company’s licensing, ownership structure, and regulatory obligations. Founders setting up in the UAE should therefore consider contract language as part of a wider formation and structuring exercise rather than in isolation.

Frequently Asked Questions

Are bilingual contracts in the UAE legally required, or can I sign in English only?

Bilingual contracts are not legally required for private commercial agreements in the UAE. You can sign a contract in English only, and it will be valid and enforceable. However, if a dispute reaches an onshore UAE court, you must file a certified Arabic translation alongside the English original. For documents that require government registration or notarisation, Arabic is mandatory from the start.

If my contract is in English and Arabic and they say different things, which version wins in a UAE court?

The Arabic version prevails in any onshore UAE court. UAE courts treat the Arabic text as the operative contract whenever there is a discrepancy between the two language versions. This applies even if both parties negotiated the deal in English. To avoid surprises, include an explicit prevailing-language clause and ensure the Arabic translation accurately mirrors the English terms.

Do I need a certified translator for my UAE bilingual contract, or can I use Google Translate?

You need a certified translator licensed by the UAE Ministry of Justice. Under Federal Law No. 6 of 2012, only MOJ-registered translators may perform legal translation for court and government purposes. A machine translation or uncertified human translation will not be accepted by onshore courts and could be rejected at filing, forcing you to start the translation process again at additional cost.

How is the Arabic-prevails rule different in DIFC and ADGM compared to onshore Dubai?

The Arabic-prevails rule does not apply in DIFC or ADGM. Both free zones operate under common-law systems with English as the official language of court proceedings. Contracts litigated in DIFC Courts or ADGM Courts can be in English only and do not require Arabic translation. In contrast, onshore Dubai courts conduct proceedings in Arabic and default to the Arabic text when two versions conflict.

What should a prevailing-language clause in a UAE bilingual contract actually say?

A prevailing-language clause should clearly state which language version controls in case of conflict. For onshore contracts, a standard clause reads: “This Agreement is executed in Arabic and English. In the event of any discrepancy between the two versions, the Arabic version shall prevail.” If parties want English to control, they should instead structure the contract under DIFC or ADGM law and jurisdiction rather than relying on a clause that might be overridden by an onshore court.

If I sign an English-only contract in the UAE, can I still enforce it in court?

Yes, an English-only contract is enforceable in UAE courts. UAE law does not void contracts for being in a foreign language. To enforce it in an onshore court, you must submit a certified Arabic translation prepared by an MOJ-licensed translator alongside the original. In DIFC or ADGM courts, you can file the English contract directly without any Arabic translation.
