Construction Contracts in UAE Federal: Complete Guide

There is no federal construction code

Contractors arriving in the UAE often look for the construction statute. There is not one. Construction contracts are governed at federal level by the Civil Transactions Law — the Civil Code — under its provisions on the contract of works, known as muqawala. Building permits, licensing of contractors and consultants, safety and inspection are handled at emirate level by the municipalities and, in free zones, by the zone authorities. Federal Decree-Law No. 50 of 2022 on commercial transactions sits alongside the Civil Code for commercial dealings, and Federal Decree-Law No. 33 of 2021 governs the workforce on site.

So the answer to "what does UAE construction law say" is almost always "what the Civil Code says about muqawala, plus whatever your emirate's authority requires to issue and close the permit."

What the Civil Code imposes regardless of the contract

The muqawala provisions are not all default rules that the parties can rewrite. Several are mandatory, and an inconsistent clause in a negotiated contract simply does not work. This is the central point for anyone drafting from an international precedent: the contract is read subject to the Code, not the other way round.

The Code also runs on the general obligation to perform contracts in good faith, which UAE courts apply with real effect. A party that exercises a contractual right in a way the court considers abusive can find the right cut back, and a strict entitlement can be softened where insisting on it would be unjust.

Decennial liability

The best known of the mandatory rules is decennial liability. The contractor and the designer are jointly liable to the employer for the total or partial collapse of the building, and for defects that threaten its stability and safety, for the period the Civil Code fixes running from handover. Any agreement to exclude or limit that liability is void.

Three consequences follow, and they are frequently missed:

• A liability cap in the contract does not cap this. The cap works for ordinary contractual claims and stops at the door of decennial liability.
• The designer is exposed even where it had no role in construction, if the defect traces to the design.
• The exposure survives the defects liability period, final account and the return of retention. Insurance and corporate structure, not drafting, are the only real answers.

Variations, lump sums and the paper that proves them

Under a lump sum contract with agreed drawings, the Civil Code does not let a contractor claim extra for additional work or design changes simply because they were instructed on site. Agreement with the employer is required, and disputes about unrecorded verbal instructions are one of the most common categories of UAE construction claim.

The discipline that wins these cases is dull: instructions confirmed in writing, variations valued and agreed as they arise, site records kept contemporaneously, and progress photographs and minutes retained. Reconstructing entitlement two years later from a spreadsheet rarely persuades a court or a tribunal.

Delay damages a court can rewrite

Agreed delay damages are enforceable in the UAE, but they are not untouchable. On the application of a party, a court may adjust the agreed sum so that it matches the loss actually suffered — downwards where the stipulated figure exceeds the real damage, and it will not simply award the contract figure where no loss occurred.

For employers, that means keeping evidence of actual delay loss rather than relying on the rate alone. For contractors, it means a punitive rate agreed under commercial pressure is not necessarily the end of the argument.

Standard forms in a civil law setting

FIDIC-based forms are the market standard across the region, and they work — provided the parties understand that the mandatory Civil Code rules override inconsistent wording. Notice and time bar provisions are the usual friction point: they are drafted on the assumption that a failure to notify extinguishes the claim, and UAE courts have not always applied them with that severity, particularly where the employer knew of the event and suffered no prejudice.

The sensible approach is to comply with the notice provisions as if they will be enforced strictly, and never to rely on the possibility that they might not be.

Money, security and tax

The payment chain is where most projects fail commercially. Advance payment guarantees, performance bonds and retention should be tied to defined events with clear release mechanics, and on-demand instruments should be identified as such, because the difference between an on-demand bond and a conditional guarantee decides whether the employer can call it during a dispute.

Tax now belongs in the commercial model. VAT applies at 5% under Federal Decree-Law No. 8 of 2017 as amended by Federal Decree-Law No. 18 of 2022, and the contract should state whether prices are inclusive or exclusive and how the tax is handled on advance payments, variations and retention releases. Corporate tax under Federal Decree-Law No. 47 of 2022 applies for financial years starting on or after 1 June 2023, at 0% on taxable income up to AED 375,000 and 9% above that; a long project spanning several financial years should have its revenue recognition and its intra-group charges looked at rather than assumed.

Labour on site

Site labour is governed by Federal Decree-Law No. 33 of 2021, which replaced the old employment law. Main contractors carry practical exposure for how their subcontractors treat workers — through wage protection requirements, accommodation and transport standards, and the summer working restrictions announced by the Ministry of Human Resources and Emiratisation. Subcontracts should require compliance, allow audit, and give the main contractor a remedy when a subcontractor's failures stop the works.

Resolving disputes

Arbitration is the usual choice on larger projects and is governed by Federal Law No. 6 of 2018, as amended in 2023. The institutional map moved under it: Dubai Decree No. 34 of 2021 abolished the DIFC-LCIA and transferred its caseload to DIAC, which leaves a stock of live contracts naming an institution that no longer exists. If a project is running on one of those clauses, the time to deal with it by agreement is now, not once a dispute has started and one side has an interest in the confusion. The onshore courts remain a perfectly workable forum, with expert determination playing a large practical role in construction cases wherever they are heard.

That is the reason the documentary discipline described above matters more than the choice of forum. A judge, a tribunal and an expert all decide on the record they are given, and on a construction project that record is either built as the work proceeds or it is not built at all. Our property dispute resolution team acts in construction claims before the UAE courts and in arbitration, and our real estate legal services team drafts and negotiates the contracts before the dispute arises.
