Common Contract Mistakes UAE Businesses Make (2026 Guide)

The most common contract mistakes UAE businesses make are signing in the wrong language, using the wrong signatory, leaving payment and interest terms vague, and copy-pasting foreign dispute resolution clauses that UAE courts will not enforce as drafted. Fix those four, and you remove most of the litigation risk that lands SMBs in court each year. As of 2026, UAE contract practice sits at the intersection of the Civil Code (Federal Law No. 5 of 1985), the new Federal Decree-Law No. 50 of 2022 on Commercial Transactions, and sector rules from MOHRE, the FTA, and the DED.

Why contract drafting in the UAE is different

Founders arriving from common-law markets often assume their templates travel well. They do not. UAE contract law is civil-code based, with mandatory rules that override what the parties write. Therefore, a clause that works in London or Singapore can be unenforceable, or worse, reinterpreted by an onshore judge.

Furthermore, the UAE has parallel legal ecosystems. Mainland contracts are governed by federal law and adjudicated in Arabic. In contrast, DIFC and ADGM operate common-law courts that accept English-language pleadings. Choosing the wrong forum at the drafting stage is one of the most expensive errors we see.

The five elements every contract still needs

Under Article 129 of the Civil Code, every contract must show offer, acceptance, a lawful object, a lawful cause, and capacity of the parties. Importantly, missing any one element can render the contract void, not merely voidable. Founders often skip capacity checks; we will return to that below.

What changed under Federal Decree-Law No. 50 of 2022

The new Commercial Transactions Law took effect on 2 January 2023 and replaced the 1993 statute. Notably, it shortened the limitation period between merchants from ten years to five, capped statutory interest at 9% per annum where the contract is silent, and expressly recognised electronic contracts and signatures, including those on blockchain platforms. The Ministry of Economy publishes the full text for reference.

The most common contract mistakes UAE founders make

After reviewing hundreds of SMB agreements, the same errors keep surfacing. Below is the shortlist worth memorising before you sign anything material.

1. Skipping the Arabic version (or getting a bad translation)

Onshore UAE courts conduct proceedings in Arabic, and the Arabic text of a bilingual contract prevails over the English in case of discrepancy. Consequently, a sloppy translation is not a cosmetic issue; it rewrites your deal. If your dispute clause sends you to Dubai Courts or Abu Dhabi Courts, invest in a certified legal translation and have counsel review both columns side by side.

2. The wrong person signing

Federal Decree-Law No. 32 of 2021 on Commercial Companies requires the Memorandum of Association to name authorised signatories and the extent of their powers. Therefore, third parties should request a specific power of attorney before transacting with anyone whose authority is not on the trade licence. The Ministry of Economy hosts the consolidated Companies Law text. If you are unsure who can sign, a notarised power of attorney is the safest path.

3. Silence on interest, VAT, and currency

Three small clauses save large arguments later:

• Interest: Specify the rate, the trigger, and whether interest compounds. Otherwise, the 9% statutory cap under Federal Decree-Law No. 50 of 2022 applies.
• VAT: Under FTA executive regulations, displayed prices must be VAT-inclusive at 5% unless the supply is for export or the customer is a registrant and the contract clearly states the price is exclusive. Say which.
• Currency: AED is default, but cross-border deals should pin the conversion date and source.

4. Copy-paste dispute clauses

“Disputes shall be resolved by arbitration in accordance with ICC rules” is not enough. The DIAC model clause requires parties to specify the number of arbitrators, the seat (Dubai or DIFC), the language, and the governing law. Without those choices, you will spend the first six months of any dispute arguing about procedure instead of substance. For lower-value commercial disagreements, structured mediation and dispute resolution often beats arbitration on cost and time.

5. Penalty clauses that judges can rewrite

UAE judges retain a statutory power to adjust penalty (liquidated damages) clauses to match actual loss. Therefore, drafting an eye-watering penalty to scare the other side rarely survives review. Instead, link the penalty to a measurable, reasonable loss, and document the commercial logic in a recital.

Employment contracts: the rules most SMBs still get wrong

Employment is where small mistakes turn into MOHRE fines and labour-court claims. Federal Decree-Law No. 33 of 2021 on the Regulation of Labour Relations in the Private Sector took effect on 2 February 2022 and reset the playbook.

Fixed-term only, in writing, registered with MOHRE

Unlimited-term private-sector contracts no longer exist on the mainland. All employment contracts must be fixed-term, in writing, and registered with MOHRE. Although the maximum term was initially capped at three years, the law was amended in 2023 to permit any duration agreed between the parties, provided the contract remains in writing.

Probation and non-compete limits

Probation is capped at six months. Post-termination non-compete restrictions must be limited in time, geography, and scope, and cannot exceed two years. Furthermore, sweeping global non-competes drafted abroad will almost certainly be struck down in UAE courts.

Comparison: where founders go wrong vs. what good drafting looks like

Issue	Common Mistake	Better Practice (2026)
Language	English-only contract for an onshore deal	Bilingual Arabic/English, with Arabic prevailing for onshore courts
Signatory authority	GM or sales head signs without proof of authority	Cross-check MOA, request specific POA for non-listed signatories
Interest on late payment	Clause silent or copies 12% from old templates	State rate within the 9% statutory cap, define trigger and compounding
VAT	“Plus applicable taxes” with no clarity	Specify VAT-inclusive or VAT-exclusive per FTA rules, list TRN
Dispute resolution	Generic ICC or “courts of London” clause	DIAC, DIFC-LCIA successor, or DIFC/ADGM courts with full seat and language specified
Limitation period	Assumes 10 years for commercial claims	Plan for 5-year limitation under Federal Decree-Law No. 50 of 2022
Employment	Unlimited-term, unregistered, generic non-compete	Fixed-term, MOHRE-registered, narrowly tailored non-compete under 2 years

Practical fixes before you sign the next contract

You do not need a 40-page template. You need a short checklist your finance, sales, and HR teams actually use. Many of our SMB clients use ongoing Outsourced In-House Legal Counsel UAE retainers precisely so this review happens before commitments are made, not after.

A 7-point pre-signature checklist

1. Confirm the signatory’s authority against the trade licence and MOA, or obtain a notarised POA.
2. Insist on a clean Arabic translation for any onshore mainland contract.
3. State whether prices are VAT-inclusive or exclusive, and list TRNs.
4. Define interest rate, late-payment trigger, and compounding (within the 9% cap).
5. Pick a real dispute forum: DIAC, DIFC, ADGM, or a named onshore court, with seat, language, and governing law.
6. Calibrate penalties to expected loss; recital the logic.
7. For employment, draft fixed-term, MOHRE-registered, with a non-compete no longer than two years.

When to call counsel

Bring in a lawyer before signing if the deal involves IP transfer, exclusivity, equity, real estate, or cross-border tax. Independent legal consultation at the drafting stage is consistently cheaper than litigation after a breakdown. For acquisitions or vendor onboarding above a meaningful threshold, layer in legal due diligence to verify the counterparty’s licences, signatory powers, and litigation history.

Frequently Asked Questions

Does a UAE contract have to be in Arabic to be enforceable?

No, a contract in English alone is still valid between the parties, but if it is litigated in onshore UAE courts it must be translated into Arabic, and the Arabic version will prevail in case of discrepancy. DIFC and ADGM courts accept English-language contracts without translation, which is one reason cross-border deals often select those forums.

What happens to a contract clause that excludes the court’s right to adjust a penalty?

UAE judges retain a statutory power under the Civil Code to adjust agreed penalty (liquidated damages) clauses to reflect actual loss, and a clause attempting to remove that power will not be enforced. Therefore, the practical fix is to draft penalties that are commercially reasonable and tied to measurable harm.

How long do I have to bring a claim under a commercial contract in the UAE?

For commercial claims between merchants, the limitation period is five years from the date the obligation became due, under Federal Decree-Law No. 50 of 2022, which came into force on 2 January 2023. This is down from the previous ten-year period; older claims may still be subject to transitional rules.

Are electronic signatures valid on UAE business contracts?

Yes, Federal Decree-Law No. 50 of 2022 expressly recognises electronic contracts and signatures, including those concluded through blockchain and similar platforms. However, certain documents that require notarisation, court filing, or land registry registration still need wet signatures or notary attestation.

Do I need a power of attorney to sign on behalf of a UAE LLC?

You need a power of attorney unless your name and powers are listed in the company’s Memorandum of Association or trade licence. Under Federal Decree-Law No. 32 of 2021 on Commercial Companies, third parties routinely request a specific notarised POA before transacting with anyone outside the named signatories.

Can a UAE employment contract still be unlimited-term?

No, all private-sector employment contracts on the mainland must be fixed-term, in writing, and registered with MOHRE under Federal Decree-Law No. 33 of 2021. Probation is capped at six months and post-termination non-compete restrictions cannot exceed two years.
