What a Dubai Interior Design or Fit Out Contract Must Include

An interior design and fit-out contract in Dubai is a Muqawala agreement under Articles 872 to 896 of Federal Law No. 5 of 1985, the UAE Civil Code. To protect your money and your property, the agreement should include an itemised bill of quantities, a milestone payment schedule with a retention sum, a defects liability period, the ten-year decennial liability that applies to structural works under Article 880, a written variation order process, and clear responsibility for obtaining the final completion certificate.

Whether the project is an apartment, a villa or an office, single-page quotations and agreements made over messaging apps leave the owner exposed to unapproved material substitutions, disputes over scope and long delays. This guide walks through each clause a fit-out contract should carry and why it matters. If you have not yet chosen a firm, start with our guide to choosing an interior designer in Dubai.

In the UAE, turnkey fit-out agreements are governed by the Muqawala provisions (contracts for work) of the UAE Civil Code. The articles most relevant to a fit-out are:

• Articles 872 to 896: the Muqawala framework for construction and work contracts.
• Article 880: the ten-year decennial liability for structural works.
• Article 882: any clause that seeks to exclude or limit that liability is void.
• Article 887: the contractor's right to compensation for client-ordered additions.
• Article 390: the court's power to adjust agreed damages.

Under Muqawala principles, the contractor must carry out the agreed works in line with the approved specifications, accepted industry practice and the agreed completion dates. The employer, meaning you as the owner, must release payments when the agreed stages are inspected and complete.

One of the most important protections in UAE construction law is decennial liability. Under Article 880 of the Civil Code, the contractor and the supervising architect or engineer are jointly liable for ten years from handover for:

1. Total or partial collapse of the structural elements they designed or built.
2. Any defect that threatens the stability or safety of the building.

Article 882 makes any clause that tries to exclude or limit this liability void. Even if a contract says the contractor's responsibility ends after the defects period, the ten-year statutory protection for structural works still applies. Most interior fit-outs are non-structural, but where your scope includes structural changes, such as removing walls or extending a villa, this protection matters.

A contract should never rely on broad lump-sum allowances. It should attach a line-by-line bill of quantities that defines the physical scope. The specification fields to look for include:

1. Joinery: veneer or laminate type, core board, edge finish and any metal trims.
2. Hardware: hinge and runner type, soft-close requirements and the specified brand or equivalent.
3. Stone: origin, thickness, slab finish and sealing.
4. MEP: pipe material and sizes, breaker ratings and diffuser types.
5. Finishes: paint system, colour references and number of coats.
6. Glass and glazing: tempered or laminated glass and thicknesses.

By binding the contractor to an itemised bill of quantities, you prevent the substitution of specified materials with lower-grade alternatives during the works, and you give both parties a fair basis for pricing any change. For how design and fit-out fees are structured, see our guide on interior design fee models in Dubai.

A fair contract matches your payments to physical progress that you or your representative can inspect. A typical schedule links payments to stages such as:

1. Mobilisation and site protection.
2. Demolition and MEP first fix.
3. Ceiling framing, plastering and screed.
4. Joinery installation and second fix.
5. Testing, balancing and commissioning.
6. Handover and the completion certificate.
7. Release of the retention at the end of the defects liability period.

A retention sum is a percentage, agreed in the contract, withheld from each progress invoice. It is your security that snagging items will be fixed promptly. A common arrangement releases half of the retention when the handover certificate is signed and the other half when the defects liability period expires. Write the percentage, the release triggers and the release dates into the contract rather than leaving them to a side letter.

The contract should define a binding defects liability period, often 12 months in UAE fit-out contracts. During that time, the contractor must attend site within an agreed response time after written notice and repair defects such as joinery misalignment, MEP leaks or settlement cracks at no cost to you. State when the period starts, whether at handover or at the completion certificate, and how defects are reported.

Changes to scope and delays are the two most common sources of fit-out disputes in Dubai. Both need clear clauses.

Under Article 887 of the Civil Code, a contractor is entitled to compensation for additions the client instructs. To keep the budget under control, the contract should state that no verbal instruction is binding. Every change should follow a written variation order, signed by both parties, that sets out:

1. The exact change to the scope.
2. The itemised cost addition or deduction, priced on the unit rates in the bill of quantities.
3. The agreed extension of time in calendar days.
4. Any re-permitting needed with Dubai Municipality, Civil Defence or another authority.

Our guide on handling changes and revisions during a fit-out project covers the variation process in more depth.

To protect you against unexcused delays, the contract should include a liquidated damages clause: a daily rate for each day of unexcused delay, and an overall cap, both stated in the contract. Under Article 390 of the Civil Code, UAE courts and tribunals can adjust agreed damages if either party shows that the actual loss was different from the agreed figure. Link the damages to the completion date in the programme, and make sure extensions of time granted through variation orders move that date.

A turnkey contract should state clearly who obtains the permits and who carries insurance. Check that it covers:

1. The contractor's responsibility for Dubai Municipality, DDA or Trakhees permits, as relevant to the property.
2. The contractor's obligation to obtain the final completion certificate.
3. Contractor's All Risk insurance for the works.
4. Third Party Liability insurance, with cover suited to the building and the scope.
5. The dispute forum: Dubai Courts, the Dubai International Arbitration Centre or the DIFC Courts.

The project is not legally complete when the keys are handed over. The contractor should stay engaged until the relevant authority issues the fit-out completion certificate or building completion certificate. For DDA areas, the process is described on the DDA fit-out completion certificate page. Our guide on the interior design and fit-out timeline in Dubai shows where completion sits in the programme.

The contract should name a forum for disputes:

• Dubai Courts: the standard onshore forum, applying UAE civil law with proceedings in Arabic.
• The Dubai International Arbitration Centre or the DIFC Courts Technology and Construction Division: often chosen for higher-value projects, with proceedings available in English and decision makers familiar with construction disputes.

Arbitration and DIFC Courts jurisdiction must be agreed in writing, so the clause needs to be specific.

What makes a fit-out contract legally binding in Dubai?

A written agreement between licensed parties under the UAE Civil Code that clearly defines the scope of work, the contract price, the payment schedule and the terms for completion.

Can a contractor in Dubai waive the ten-year decennial liability?

No. Under Article 882 of the UAE Civil Code, any clause that tries to exclude or limit the decennial liability set by Article 880 is void.

How much retention is held in a UAE fit-out contract?

The retention is a percentage agreed in the contract and withheld from interim payments. It is usually released in two parts, at handover and at the end of the defects liability period.

How are variation orders priced during a Dubai fit-out?

Variation orders should be priced using the unit rates in the original bill of quantities, with an agreed adjustment to the completion date, and signed before the work starts.

Why name DIAC or the DIFC Courts in the dispute clause?

They offer proceedings in English and decision makers familiar with construction disputes. The choice must be written into the contract to apply.
