Tenancy Addendum (UAE)

A Tenancy Addendum in the United Arab Emirates is the written instrument by which a landlord and tenant agree to modify, supplement, or extend the terms of an existing tenancy contract without replacing the original agreement in its entirety. The addendum records the specific changes agreed between the parties, declares that all other terms of the original contract remain in force, and is signed by both parties to create a binding amendment.

In Dubai, all residential tenancy contracts are governed by Law No. 26 of 2007 Regulating the Relationship between Landlords and Tenants in the Emirate of Dubai, as amended by Law No. 33 of 2008, and must be registered on Ejari through the Real Estate Regulatory Agency (RERA) of the Dubai Land Department (DLD). The Ejari system records the key terms of the tenancy — the parties, the property, the rent, and the term — and public bodies, utilities, and the Rental Disputes Settlement Centre (RDSC) rely on the registered Ejari certificate. When a material term of the tenancy changes, the Ejari registration should be updated to reflect the current agreement.

The UAE Civil Code (Federal Law No. 5 of 1985) provides the contractual framework for amendments to leases. Under the Civil Code, a contract can be varied by written agreement of the parties, and the variation is binding from the date agreed. The addendum is the documentary form of that variation. Without a written addendum, a verbal agreement to change rent, extend a term, or add a party is not enforceable before the RDSC, which requires written evidence of any contractual variation.

Tenancy addenda are used in a wide range of situations. A rent adjustment addendum documents an agreed increase or reduction in rent, referencing the RERA Rental Index and confirming compliance with Decree No. 43 of 2013 where a renewal increase is involved. A term extension addendum prolongs the tenancy beyond its original expiry date and triggers an Ejari update. A maintenance addendum reassigns repair obligations between landlord and tenant following a change in building management. A permitted-use addendum records the landlord's consent to a new permitted use, such as allowing the tenant to register a home-based business at the property.

A well-drafted addendum saves both parties from later disputes about whether a verbal agreement was ever reached, what its precise terms were, and whether it was legally effective. The RDSC has consistently held that tenancy contract amendments must be in writing to be enforceable, and a signed addendum with the Ejari registration reference and the date of effect is the clearest evidence available.

The addendum does not create a new tenancy: it modifies an existing one. The original contract's commencement date, the existing Ejari reference, the property description, and the identities of the parties all carry over. Only the terms specifically amended in the addendum change. This distinction is important for the calculation of any notice periods, for the application of the RERA rent cap on future renewals, and for the continuity of the Ejari registration record.

A Tenancy Addendum in the United Arab Emirates is needed whenever landlord and tenant agree to change the terms of a subsisting tenancy without terminating and re-entering the original agreement. The circumstances that commonly give rise to an addendum are varied and arise throughout the life of a tenancy.

A rent adjustment addendum is needed when the landlord and tenant agree to vary the annual rent — whether up or down — during the currency of the term. This may occur because the tenant has negotiated a temporary rent reduction during a period of financial difficulty, or because the landlord and tenant have agreed to a voluntary early increase in exchange for a longer commitment. An addendum is also needed to document a rent reduction agreed as a condition of the tenant undertaking maintenance works that are formally the landlord's obligation.

A term extension addendum is needed when the parties agree to continue the tenancy beyond its original expiry date, either for a fixed further period or on a rolling basis. Extending by addendum avoids the formalities of issuing a new tenancy contract, though the Ejari registration must be updated to reflect the new expiry date, particularly where the Ejari certificate is relied upon for visa renewals.

A permitted-use addendum is needed when the tenant's use of the property changes, for example where a residential tenant wishes to register a home-based business at the property address, or where a commercial tenant expands its permitted retail categories. The landlord's written consent to the changed use, documented in an addendum, prevents a later argument that the tenant breached the use covenant of the original contract.

A maintenance addendum is needed when the parties agree to reallocate repair obligations, for example following a change of property management company, the installation of new building systems, or a dispute about who is responsible for specific items. Clarifying the maintenance boundary in writing avoids the recurring friction of verbal understandings.

An early termination addendum is needed when both parties agree to end the tenancy before its natural expiry. The addendum records the agreed termination date, any settlement payment, the deposit return terms, and the handback conditions. This is a cleaner approach than attempting to rely on a unilateral break clause that was not in the original contract.

In all cases, the addendum should be executed before the amended term takes effect, signed by both parties, and kept with the original tenancy contract and Ejari certificate as part of the tenancy record.

A Tenancy Addendum for premises in the United Arab Emirates should contain a defined set of elements to ensure the amendment is clearly documented, enforceable before the Rental Disputes Settlement Centre (RDSC), and capable of supporting an updated Ejari registration where required. The forms-legal.com Tenancy Addendum template captures each of these elements.

Reference to the original contract is the defining feature of an addendum. The addendum must identify the original tenancy contract by its execution date and, where the tenancy is registered on Ejari, by the Ejari reference number. The RDSC and DLD use the Ejari reference to locate the underlying tenancy record. Without a clear cross-reference to the original contract, the addendum could be treated as a standalone agreement rather than an amendment, with potentially unpredictable results.

Property identification must confirm the premises address. This ties the addendum to the physical property and cross-checks that the parties are amending the correct contract where a landlord or tenant holds multiple tenancy agreements.

Party confirmation must state the landlord's and tenant's full names as they appear in the original contract. Any change of party — for example, where a company assigns the tenancy to a successor entity — should be the subject of a separate assignment document rather than an addendum.

Amendment type and description are the substantive heart of the addendum. The amendment type should be selected from a defined list — rent adjustment, term extension, permitted-use addition, maintenance change, or early termination — and the description must state precisely what is changing, identifying the specific clause of the original contract that is affected and providing the new wording. A description that says only 'the rent is being increased' without the new rent figure, the effective date, and the legal basis is insufficient.

Effective date must be stated unambiguously, because the change is binding from that date and not from the date the addendum is signed. Where the addendum documents a rent increase, the effective date is the date from which the new rent is payable, which must be consistent with the 90-day notice requirement under Article (1) of Law No. 33 of 2008 where applicable.

Rent-cap compliance confirmation is necessary where the addendum records a rent increase. The parties should confirm that the increase has been verified against the RERA rental increase calculator and that it does not exceed the cap under Decree No. 43 of 2013, or alternatively that the increase is a freely agreed contractual variation not triggered by a unilateral renewal notice.

Ejari update confirmation records whether the parties agree that the addendum requires an updated Ejari registration. This guides the party responsible for the Ejari update and provides a record if the DLD later queries the currency of the Ejari record.

Savings clause confirms that all other terms of the original contract remain in full force, limiting the addendum's effect to the specific changes listed and preventing an argument that the addendum novated the entire contract.

Completing a Tenancy Addendum for a UAE tenancy requires accessing the original tenancy contract and Ejari certificate before beginning, to ensure that all cross-references are accurate.

Start by entering the date of the original tenancy contract in the DD/MM/YYYY format. Locate the Ejari reference number on the Ejari certificate issued at the time of registration and enter it in the Ejari reference field. If the tenancy has not been registered on Ejari, leave the field blank, but note that an unregistered tenancy has limited standing before the RDSC. Enter the property address exactly as it appears in the original contract.

In the parties section, enter the landlord's full name and the tenant's full name exactly as they appear in the original tenancy contract. Any discrepancy between the names in the original contract and in the addendum may cause the RDSC to question whether the addendum relates to the correct tenancy.

In the amendments section, select the amendment type from the dropdown. Then complete the description field with a precise statement of the change. Use the following structure: identify the clause being changed (for example, 'Clause 3.1 of the Original Contract is amended to read:'), then state the new wording in full. If multiple clauses are being changed, list each separately. Enter the effective date — the date from which the change operates.

For a rent adjustment, state the current rent, the new rent, and the percentage increase. Confirm that the increase was checked against the RERA rental increase calculator and falls within the Decree No. 43 of 2013 cap, or confirm it is a voluntary contractual variation. For a term extension, state the new expiry date and note that Ejari will need to be updated.

In the additional conditions field, add any conditions that apply to the amendment — for example, the tenant's confirmation of receipt of the required 90-day notice, or the landlord's agreement to carry out specified repairs as consideration for the tenant's acceptance of a rent increase.

Once generated, both parties should sign and date the addendum. Retain it with the original tenancy contract and Ejari certificate. Where an Ejari update is needed, take the signed addendum to an Ejari typing centre or use the Dubai REST app to update the registration record.

Legal requirements for a Tenancy Addendum in the United Arab Emirates are defined by Law No. 26 of 2007 as amended by Law No. 33 of 2008, Decree No. 43 of 2013, and the UAE Civil Code (Federal Law No. 5 of 1985).

Written form is the fundamental requirement. The RDSC consistently holds that any amendment to a tenancy contract must be in writing and signed by both parties to be enforceable. A verbal agreement to change the rent, extend the term, or modify obligations is not recognised as a variation of the registered Ejari contract.

Rent increase compliance is mandatory where the addendum documents a renewal rent increase. Decree No. 43 of 2013 caps increases on renewal according to the RERA Rental Index, with the maximum increase at 20% for properties more than 40% below the market average. Article (1) of Law No. 33 of 2008 requires 90 days' written notice before the expiry of the current term for any proposed change to the rent or other terms. An addendum documenting a rent increase without the required notice, or in excess of the permitted cap, is unenforceable as to the excess, and the tenancy renews on the original terms.

Ejari update requirements arise from Dubai Land Department policy: a material change to a registered tenancy — including a change of rent, extension of term, or change of party — should be reflected in an updated Ejari registration. The DLD's Ejari system is the authoritative record of tenancies in Dubai, and an Ejari certificate that does not reflect the current agreement may undermine the party's position in RDSC proceedings or cause difficulties with utilities and visa authorities.

Cancellation of the tenancy by mutual addendum, if the parties agree to end the tenancy early, must record that the landlord returns the Ejari registration fee (or a portion of it) and that the deposit is settled. The DLD has procedures for early cancellation of an Ejari registration.

For commercial tenancies, the UAE Commercial Transactions Law (Federal Decree-Law No. 50 of 2022) and the Commercial Companies Law (Federal Decree-Law No. 32 of 2021) apply where the parties are companies, affecting the authorised signatory requirements for executing the addendum on behalf of each entity. A director or authorised manager with a company board resolution or power of attorney authorising the variation should sign.

Common mistakes with a Tenancy Addendum in the United Arab Emirates frequently result in the amendment being unenforceable or in disputes before the Rental Disputes Settlement Centre (RDSC) that the written addendum was intended to prevent.

The most common mistake is insufficient description of the amendment. An addendum that says 'the rent is increased by AED 5,000' without stating the current rent, the new rent, and the effective date is ambiguous and may not be accepted by the RDSC as a definitive amendment to the original contract. Always state the full text of the clause as it reads after the amendment.

Failing to update Ejari after a material amendment creates a record-keeping gap. Where the addendum extends the tenancy term or changes the rent, the Ejari certificate will continue to show the original terms until updated. A tenant who relies on an expired Ejari certificate for a visa renewal or a DEWA connection may find the request rejected. Both parties should agree in the addendum which of them will initiate the Ejari update and within what timeframe.

Attempting to document a unilateral rent increase by addendum, without the required 90-day notice under Article (1) of Law No. 33 of 2008, produces an addendum that the tenant can challenge as procedurally defective. The RDSC will inquire when the notice was served and whether the 90-day window was observed. An addendum that post-dates the required notice period and purports to make the increase effective retrospectively may be set aside.

Documenting a rent increase above the Decree No. 43 of 2013 cap is another serious error. Even if both parties sign the addendum, a tenant who later discovers the increase exceeded the lawful maximum may bring an RDSC claim to recover the excess paid. The cap operates as a public-policy limit that the parties cannot contract out of in the context of a renewal rent increase.

Finally, using a generic contract amendment template that refers to laws or systems not applicable to the specific Emirate — for example, citing Ejari and the RDSC for a property in Abu Dhabi — undermines the document's authority. In Abu Dhabi, tenancies are registered through Tawtheeq and disputes go to the Abu Dhabi Judicial Department. Addenda for non-Dubai properties must reference the correct registration system and dispute forum.
