Royal Decree-Law 8/2026 has opened a window of opportunity for more than two million tenants in Spain. If your rental contract expires before 31 December 2027, you have the right to two additional years in the same conditions, with rent increases capped at 2%.
But that right does not come automatically. You must request it in writing, with proof of delivery, before the contract ends.
This guide explains exactly what the law says, how to make the most of it, and what tools you have to notify the extension with full legal validity.
What is the extraordinary rental extension and why does it exist
Royal Decree-Law 8/2026, dated 20 March, was approved by the Spanish Government as an emergency measure in response to the economic impact of the conflict in the Middle East.
Its aim is to protect tenants in a strained rental market, where an estimated more than 600,000 contracts were at risk of expiry in the coming months.
The decree came into force on 22 March 2026, published in the Official State Gazette (BOE) the day before, and its effects are fully enforceable from that date regardless of any subsequent parliamentary ratification.
Why acting quickly makes legal sense
A Royal Decree-Law is a complete and fully effective piece of legislation from the moment it is published in the BOE. The right to the extension was born on 22 March 2026 and can be exercised from that moment.
The key point is that rights already consolidated are not affected by any subsequent repeal. Whoever correctly requests the extension while the decree is in force, keeps it. Whoever waits and the decree is repealed, loses it.
This is why acting promptly is not optional — it is the most legally prudent decision.
Who the RDL 8/2026 applies to
The extraordinary extension applies to contracts for the rental of a main residence that meet all of the following requirements:
Subject to the LAU: the contract must fall under the Urban Leases Act (Law 29/1994), which is the general legislation governing long-term rentals in Spain.
In force on 22 March 2026: the contract must be active on the date the decree entered into force. Contracts that had already expired cannot benefit from this measure.
Expiring before 31 December 2027: the period of mandatory extension (art. 9.1 LAU) or tacit extension (arts. 10.1 and 10.2 LAU) must end within that deadline.
If your contract meets these three requirements, you have the right to request the extension.
Contracts that do NOT qualify
The decree does not apply to non-residential leases (commercial premises, warehouses, standalone parking spaces), seasonal rentals, or contracts covering a secondary residence rather than the tenant’s main home.
How long the extension lasts and under what conditions
The extraordinary extension is granted in annual instalments, up to a maximum of two additional years beyond the original expiry date of the contract.
This means you can request one or two extra years. The extension starts from the original expiry date, not from the moment of the request. If your contract ends on 1 September 2027 and you request two years, it will be extended until 1 September 2029.
Economic conditions during the extension
During the two-year extraordinary extension, the same terms and conditions of the existing contract apply. This includes the current rent, maintenance obligations and all the clauses of the original agreement.
The only permitted change is the annual rent update, which is capped at a maximum of 2%, with no possibility of being linked to the CPI or any higher index.
For landlords who are not large-scale holders (fewer than 10 properties, or fewer than 5 in stressed zones), it is possible to agree with the tenant on a percentage above 2% if both parties expressly consent. In the absence of agreement, 2% is the applicable ceiling.
Incompatibility with the art. 10.3 LAU extension
The decree is incompatible with the extraordinary extension provided for in article 10.3 of the LAU, which takes precedence when applicable. If you already have a right to that extension, you cannot also claim the one under RDL 8/2026.
When and how to request the extraordinary extension
The extension does not operate automatically. You need to give formal notice to the landlord, in writing, with proof of delivery, before the contract ends.
The right moment to request it
The request should be made when the contract is genuinely approaching its expiry date, in line with the standard notice periods of the LAU. It is not a right you can activate years in advance — it is a faculty that becomes relevant when the parties must decide on the continuation of the tenancy.
If the landlord has already notified you of their intention not to renew, or the deadline is approaching, act without delay.
What the request must include
For the notification to be valid and the right properly consolidated, the communication to the landlord must contain:
Contract identification: address of the property, date of signature and anticipated expiry date.
Express reference to RDL 8/2026: state that you are exercising the right recognised in article 1 of Royal Decree-Law 8/2026, dated 20 March.
Duration requested: one or two additional years, in annual instalments.
Date and signature of the tenant: to establish who is exercising the right.
How to prove you sent it
This is the critical point. The decree requires proof of delivery that allows you to demonstrate the landlord received the request. Without that proof, the right may be left in limbo.
Valid methods include: registered post with acknowledgement of receipt (burofax), certified email or in-person delivery with the landlord’s signature. An electronic signature on the document, combined with a certified sending system, further strengthens the solidity of the notification.
A WhatsApp message, a regular email or a phone call are not valid as proof of delivery. If the landlord denies having received the request and you have no evidence, you will have lost the right even if you acted in good faith.
Registered post vs. certified email: which to use to notify the extension
The most common question among tenants is: which is better, registered post or certified email?
The answer is that both are legally valid when used correctly. The difference lies in the practicality and the cost.
Registered post: maximum guarantees, but slow and expensive
The traditional registered post with acknowledgement of receipt remains the most recognised method for this type of notification. It offers full legal guarantees and is widely accepted by courts.
Its downside is that it requires a physical visit to a post office, has a significant unit cost and delivery can take days. In a context where deadlines are strict, that can be a problem.
Certified email: same guarantees, faster and cheaper
Certified email issued by an accredited trusted third party generates evidence equivalent to registered post: timestamp, registered content, recipient identification and a downloadable PDF certificate.
The operational difference is significant: the send is made from your regular email, it arrives in seconds and the certificate is immediately available, with no travel or waiting. This makes it the most practical option for most tenants.
The data loss risk inherent in informal communications — messages that disappear, inboxes that get deleted, screenshots that can be manipulated — is precisely what certified email eliminates. Every send is preserved as immutable, verifiable evidence.
The probative reliability of a notification does not depend on the channel chosen, but on that channel generating complete, verifiable evidence. Certified email meets that requirement when the system is properly accredited under the EIDAS regulation.
What happens if the landlord refuses or does not respond
The extension request must be mandatorily accepted by the landlord, except in the three specific cases provided for in the decree. If the landlord refuses without legal grounds or simply does not respond, the tenant has several options.
The three legal exceptions to the duty to accept
The landlord can only deny the extension in these cases:
The parties have reached an agreement with different conditions from those in the existing contract.
A new rental contract has been signed between the parties.
The landlord has given notice, within the timeframes and conditions of article 9.3 of the LAU, of the need to occupy the property for personal use or for first-degree relatives.
Outside these three cases, the refusal has no legal basis. And if the landlord fraudulently invokes the personal use exception, the decree includes a specific sanctioning regime.
If the landlord claims they need the property
This is the most common exception and also the most susceptible to fraudulent use. If the landlord claims the need to occupy the property but does not actually do so within three months of the contract ending, the tenant has the right to return to the property under the previous conditions, or to receive compensation of one monthly rent for each year remaining of the extension.
To exercise that right, it is essential to have preserved all documentation of the process: the extension request, the landlord’s response and the certificate of the send.
The role of certified email in disputes
If the landlord denies having received the extension request, the PDF certificate from the certified email provides the necessary evidence: exact date and time of the send, recipient’s address and full content of the message.
This evidence is sufficient to prove before a court that the notification was properly made, shifting the burden of proof to the landlord.
How to make the most of the two-year extension
Beyond the initial notification, the two-year extension offers a valuable window of time that is worth managing actively.
Review the contract conditions before requesting
Before sending the request, go through the terms of the existing contract. The extension maintains those conditions, so if there is any unfavourable clause, this may be the moment to try to renegotiate it with the landlord before locking in the extension on its current terms.
If landlord and tenant agree on a lower rent than the one in the existing contract, the extraordinary extension under RDL 8/2026 does not apply, and the parties regulate their relationship by what they have agreed. This can be an opportunity for the tenant if the market has softened in their area.
Plan your housing search with real breathing room
Two years is a reasonable horizon to look for an alternative property without the pressure of an imminent eviction. Use that time to save, search calmly and analyse purchase or rental options without urgency.
Document the condition of the property
At the start of the extension period, carry out a photographic inventory of the state of the property and send it to the landlord via certified email. This protects the tenant from potential claims about damage at the end of the extension and establishes a documented reference for the condition at the start of the extraordinary period.
The use of certified notifications for this type of preventive communication is a practice increasingly adopted by tenants and property managers to protect their position in case of later disputes. For property managers looking for comprehensive certified communication tools, see our guide on Certified email software for property managers.
Monitor rent updates
During the extension, the landlord can only increase the rent by a maximum of 2% per year. If you receive a notice of a higher increase, you have the right to challenge it.
Always keep any communication about rent in writing: the landlord’s notice, your response and any agreement reached. A certified notification of your objection to an illegal increase strengthens your position and stands as evidence if the matter goes to court.
Practical cases: when RDL 8/2026 applies and when it does not
Case 1: contract with mandatory extension expiring in 2026
Your contract signed in 2021 reaches its five-year minimum duration in 2026. The landlord notifies you they do not want to renew. You can request the extraordinary extension because the end of the mandatory extension falls before 31 December 2027.
Case 2: contract on tacit extension expiring in 2027
Your contract has already passed the five-year mark and is on annual tacit rollover. The landlord gives you four months’ notice of non-renewal. If that expiry is before 31 December 2027, you can request the extraordinary extension.
Case 3: the landlord has sold the property
If the property has changed hands, the new landlord takes on the contract with all its conditions. The extraordinary extension applies equally, because the contract is the same and a change of ownership does not extinguish the tenant’s rights under the LAU.
Case 4: seasonal rental or secondary residence
If the contract is not for a main residence or falls under seasonal rental rules, RDL 8/2026 does not apply. This is one of the most common sources of confusion, especially for tourist rentals or short-term contracts signed as seasonal tenancies.
Case 5: the landlord claims they need the property
You have the right to ask for documentation proving that need. If the landlord does not actually occupy the property within three months, you have the right to return or to be compensated. Document everything with certified emails from the outset to build a solid file. Maintaining the integrity of those documents — ensuring nothing can be altered after the fact — is as important as preventing certified Email Software for managing unpaid debts from being challenged on the grounds of tampering.
The role of property managers in managing the extension
Property managers handling rental portfolios play a key role in the application of RDL 8/2026, both on the landlord side and the tenant side.
For landlords: how to handle incoming requests
The property manager should advise the landlord on whether the extension request received is valid, whether any of the three legal exceptions apply and what the most appropriate response is in each case.
It is essential that any communication with the tenant about the extension is documented through certified notification. Responding to an extension request via WhatsApp or verbally can create disputes about whether acceptance took place and on what terms.
For tenants: support with notification and follow-up
The property manager can handle the sending of the extension request on behalf of the tenant, ensuring the content is correct, the channel is valid and the evidence is properly preserved.
In portfolios with multiple contracts approaching expiry, API-based automation with a certified email system allows dozens of notifications to be managed in parallel, maintaining individual evidence per contract.
When there are disagreements about the content of a notification or a landlord claims not to have received it, certified SMS software for management firms as a complementary channel to certified email strengthens the position of either party.

Frequently Asked Questions (FAQs)
Is the RDL 8/2026 extension automatic?
No. The tenant must expressly request it from the landlord in writing with proof of delivery. Without that request, the contract ends on its scheduled date.
Do I need to wait for the landlord to notify me before I can request the extension?
No. The decree expressly states that the landlord does not need to have given notice of non-renewal for the tenant to exercise the right. The extension arises directly from the law and only requires the tenant to request it.
How long do I have to request it?
The request must be made before the contract ends and while the decree is in force. The most prudent interpretation is to do so when the expiry is genuinely approaching, within the standard LAU notice period logic.
Can I request just one year instead of two?
Yes. The extension is granted in annual instalments and you can request one or two additional years. At the end of the first year of extension, you can request the second if you did not do so initially.
Can the landlord increase the rent during the extension?
Only by a maximum of 2% per year. Any higher increase has no legal basis during the extraordinary extension period.
What happens if the decree is repealed before my contract expires?
If you have already correctly requested the extension while the decree was in force, your right is consolidated and any subsequent repeal does not affect you. If you have not yet requested it and the decree is repealed, you lose the protection.
Can I use a regular email to notify the extension?
No. You need a method that generates valid proof of delivery: registered post, certified email or in-person delivery with signature. A regular email does not prove the landlord received it or that the content was as notified.
