This is the single most important legal update for Dubai property buyers and tenants in 2026 — and one that most real estate content hasn't caught up to yet.
On 1 June 2026, Federal Decree-Law No. 25 of 2025 came into force, repealing and replacing the 1985 Civil Code — the foundational law that has governed civil and contractual relations in the UAE for four decades. This isn't a minor amendment; it's the most significant overhaul of UAE civil law since 1985, and it has direct, practical implications for anyone buying, selling, or leasing property here.
What Actually Changes for Real Estate Transactions
1. Mandatory pre-contractual disclosure duties. The new law introduces an explicit statutory duty of good faith and disclosure during negotiations — before a contract is even signed. For property transactions, this has particular relevance to reservation agreements, Memoranda of Understanding (MOUs), and heads-of-terms documents. Courts may now examine more closely what information was disclosed during negotiation, what assumptions were made, and whether any undisclosed matter was material to a buyer's decision to proceed. Developers, sellers, and institutional landlords should expect — and prepare for — closer scrutiny of what's disclosed (or left undisclosed) before a deal is signed.
2. Extended latent defect protection. The limitation period for claiming hidden (latent) defects has been extended from six months to one year from delivery, unless a longer guarantee is separately agreed. Buyers now have meaningfully more time to discover and claim for defects not visible at handover — a direct, practical upgrade in buyer protection, especially relevant for off-plan and newly handed-over units.
3. Clearer remedies for sale-contract issues. Under the updated law governing "sale by sample" and "sale by model" — directly relevant to off-plan purchases sold via show units and floor plans — buyers now have clearer legal standing to reject the property, accept it with a price reduction, or request a defect-free replacement when delivered units don't match what was represented.
4. Lease-related clarifications. Where Dubai's emirate-level landlord-tenant laws don't explicitly address an issue, the new Civil Code now fills the gap with federal provisions — including confirmation that holding over (staying in a property after a lease expires) generally creates a new lease rather than simply extending the old one, and clarified landlord security rights over certain tenant property.
5. Enhanced protection against grossly undervalued sales. The law adds specific protections for individuals lacking full legal capacity in cases of grossly inadequate real estate sale prices — a safeguard against exploitation in distressed or rushed transactions.
6. Reduced legal age of majority. The age of legal capacity drops from 21 lunar years to 18 Gregorian years, which strengthens contract enforceability for buyers and signatories in the 18–20 age range and reduces capacity-based disputes.
What This Means in Practice
Property and real rights remain primarily governed by Dubai's emirate-level real estate laws — the new federal Civil Code operates alongside, not instead of, DLD and RERA regulations. But for contract drafting, disclosure practices, and dispute risk, every party to a Dubai real estate transaction — buyers, sellers, agents, and developers — should expect template documentation, MOUs, and standard-form contracts to be reviewed and updated to reflect the new statutory duties.
Important transitional note: the new law generally doesn't apply retroactively. Contracts signed before 1 June 2026 remain governed by the 1985 Civil Code's provisions as they stood at signing. However, amendments, renewals, or ongoing performance of existing contracts after that date may fall under the new framework — so if you're renewing a lease or amending an existing property contract in the second half of 2026, it's worth confirming which legal regime applies to the specific clause in question.
