The UAE Replaced Its Civil Code on 1 June 2026: What It Means for Dubai Property

On 1 June 2026 the law sitting underneath every property contract in the United Arab Emirates was replaced. Not amended. Replaced.

Federal Decree-Law No. 25 of 2025, issuing the Civil Transactions Law, repealed Federal Law No. 5 of 1985 and its amendments in full. The 1985 Civil Code had governed contracts, obligations, ownership and security rights across the country for forty years, and it is the instrument that almost every legal argument about a Dubai sale and purchase agreement, a construction contract or a co-ownership dispute ultimately ran through.

Property coverage of the change has been close to non-existent, which is understandable but wrong. The headline reforms are contractual rather than registrational, so nothing about a title deed looks different. But the contract is where Dubai property deals are actually won and lost, and the rules for forming one have moved.

What Was Replaced, and When

The dates are worth stating precisely, because secondary sources already disagree about them.

• The decree-law was issued on 1 October 2025.
• It was published in Official Gazette No. 809 on 14 October 2025.
• It came into force on 1 June 2026, giving the market roughly seven and a half months of notice.
• It repeals Federal Law No. 5 of 1985 and its amendments.

The structure is a recodification rather than a patch. The new law runs to over 1,400 articles across four books: obligations, named contracts, real rights and security rights. Sale, lease, muqawala construction contracts, gift, mortgage, ownership and co-ownership all sit inside it.

At least one international firm's client alert gives the issuance date as 30 December 2025. The gazette record says 1 October 2025, and where a published gazette reference exists it is the one to follow.

The Thing to Understand First: Dubai's Own Property Laws Did Not Move

This is the point that decides whether you need to do anything, and it is reassuring.

Property in Dubai is governed by a stack of emirate-level instruments that the federal Civil Code does not touch. Law No. 7 of 2006 on real property registration. Regulation No. 3 of 2006 defining the areas where non-UAE nationals may hold freehold. Law No. 26 of 2007 as amended by Law No. 33 of 2008 on tenancy. Law No. 13 of 2008 on the interim real estate register. Law No. 14 of 2008 on mortgages. Law No. 6 of 2019 on jointly owned property. Law No. 3 of 2026 on building quality and safety. Decree No. 43 of 2013 on rent increases.

None of those were repealed or amended on 1 June 2026. Your title deed, your Ejari, your service charge obligations, your rent increase cap, your eviction notice periods and the Rental Dispute Centre's jurisdiction are all exactly where they were.

What the Civil Code does is sit underneath them. It supplies the general law of contract that an SPA, a Form F, a tenancy contract or a construction contract is built out of, and it fills every gap the emirate-level laws leave. Which is why a change at that level reaches further than it first appears.

Negotiations Now Carry Duties Before Anything Is Signed

This is the most consequential change for anybody buying or selling property, and it is genuinely new.

The new law regulates the pre-contractual stage expressly. Negotiations must be conducted, and broken off, in good faith. A party who negotiates in bad faith is liable for the other party's actual damages. Withholding material information during negotiations is treated as bad faith, and the disclosure obligation cannot be excluded by agreement.

Read that against how Dubai property is actually sold.

A seller who knows the tower has an unresolved structural issue, a developer representative who knows the handover date has already slipped internally, an owner who knows a special levy has been approved but not yet billed, a landlord selling a tenanted unit who knows the tenant is disputing the rent increase. Under the old code the buyer's protection was largely whatever the contract said and whatever misrepresentation they could prove. Under the new one there is a freestanding duty to disclose material information during negotiations, which cannot be contracted away.

The practical effect runs both directions. A buyer gains a route they did not have. A seller who answers a direct question evasively has acquired a liability that no "as seen" clause in the Form F will neutralise.

Two things to do about it. Ask material questions in writing, so the answer exists. And answer them in writing, accurately, for the same reason.

Hidden Defects: One Year, Not Six Months

The period for a buyer to raise a hidden defect has been extended from six months to one year.

For property this reaches beyond the obvious. The snagging period a developer offers at handover is a contractual term and unaffected, as is the one-year defects liability and ten-year structural liability that construction contracts carry. The hidden-defect rule is the general law backstop for the sale itself, and it now runs twice as long as it did.

For a seller the implication is that a resale property's latent problems stay live for a full year after transfer. For a buyer it means a defect discovered in month eight is no longer automatically out of time.

When Circumstances Change: Contractual Equilibrium

The new law empowers a court to restore the balance of a contract where exceptional, unforeseeable circumstances make performance gravely onerous, rather than merely more expensive.

This matters in a market built on long off-plan payment plans and multi-year construction contracts. It is not a general escape from a bad deal, it is a narrow doctrine that has to clear a high bar, and any lawyer will tell you it is pleaded far more often than it succeeds. But it exists, it is expressly stated, and it belongs in the risk assessment on contracts whose performance runs for years.

Musataha Must Be Registered or It Is Void

One change is squarely a property change. A musataha right, the right to build on and exploit land belonging to someone else, must now be registered, and an unregistered musataha is null and void.

In Dubai this is less dramatic than it sounds, because musataha rights in the emirate are registered with the Land Department as a matter of course and appear on the register alongside freehold and usufruct. Where it bites is at the margins: informal arrangements, unregistered side agreements over plots, and structures built under an understanding rather than a registered right. If you hold or have been offered anything in that category, the question of whether it is registered is no longer a procedural detail.

Every Article Number in an Older Guide Now Points at a Repealed Law

This is the trap worth carrying away, and it is the reason this post exists.

The recodification renumbered everything. Co-ownership, which generations of UAE lawyers cited in the 1130s and 1160s of the old code, now sits in a different range entirely. In the new text the general co-ownership provisions begin in the 1050s, the right of every co-owner to demand partition and the five-year ceiling on an agreement to stay in co-ownership appear at Article 1063, the rule for property that cannot be divided without harm appears at Article 1067, and pre-emption between co-owners begins at Article 1171.

So any guide, template, memorandum or blog post written before 2026 that cites a Civil Code article by number is citing a law that has been repealed. The underlying principle has usually survived the move, but the citation has not, and a demand letter quoting a dead article number is an easy thing for the other side to dismiss.

Two rules follow. Treat pre-2026 article numbers as pointing to the old code until someone confirms the new one. And when a lawyer quotes you an article, ask which code it is from.

Does It Apply to My Existing Contract?

Broadly, no, and that is the design.

The new law applies prospectively, to contracts and transactions entered into from 1 June 2026, subject to specific transitional rules. The most commonly cited of those concerns limitation periods that had not yet expired when the law came into force.

That means an SPA signed in 2023, a tenancy contract renewed in 2025 and a construction contract concluded in 2024 remain governed by the 1985 code for the purposes of their formation and terms. Anything you sign from this year onward does not. Where a contract straddles the boundary, through a variation, a novation or an assignment, the answer is a question for a lawyer rather than for a guide, and it is the single most likely place to get this wrong.

One Quiet Change Worth Knowing

The age of majority has been lowered from 21 lunar years to 18 Gregorian years.

For property this is narrow but real. It changes who can sign an SPA, hold a registered interest in their own name and give a valid power of attorney without a guardian. Families who have been structuring purchases around a child reaching 21 should check the position, and anybody who has drafted documents assuming the old threshold should have them reviewed.

The Short Version

Federal Decree-Law No. 25 of 2025 was issued on 1 October 2025, published in Official Gazette No. 809 on 14 October 2025 and came into force on 1 June 2026, repealing the 1985 Civil Code in full. None of Dubai's emirate-level property laws changed, so title deeds, Ejari, rent caps, eviction notices, service charges and the Land Department's processes are untouched. What changed is the general law of contract underneath them: negotiations now carry an express good-faith and disclosure duty that cannot be contracted out of, the hidden-defect period has doubled to one year, courts may restore the balance of a contract disrupted by exceptional circumstances, and an unregistered musataha right is void. The law applies to contracts entered from 1 June 2026 onward, subject to transitional rules, so older contracts stay under the old code. And because the whole code was renumbered, every article number in a pre-2026 guide now cites a repealed law, which is worth checking before anybody quotes one at you.
