Spain's Single Rental Register annulled: what Supreme Court ruling 620/2026 says and what remains in force

In May 2026 the Supreme Court annulled the Single Rental Register (Registro Único de Arrendamientos): the State cannot require you to enter your accommodation in the Land Registry in order to get a number and advertise it on platforms. The Digital Single Window for Rentals (Ventanilla Única Digital de Arrendamientos) and the platforms' obligation to send data on each accommodation both remain in force. The key ruling is 620/2026, of 19 May, and its operative part was published in the BOE on 8 June 2026. The tourism registers of each autonomous community are not annulled by it.

This guide explains what fell, why, what remains in force and what you need to check with your region. It is based on the text of Real Decreto 1312/2024 as the BOE publishes it today (with the annulments noted) and on the text of the rulings. It does not replace the advice of a professional who knows your case.

The dates at a glance

On the date it takes effect: the BOE's analysis sheet says "1 June 2025", but the text of the fourth final provision says the royal decree takes effect "on 1 July 2025". Here we follow the text of the rule itself.

What the Supreme Court annulled

Ruling 620/2026 annuls the provisions "relating to the single rental registration procedure and the obligation to register in the Land Registry or the Movable Property Registry in order to obtain a registration number". Specifically, according to the operative part published in the BOE (BOE-A-2026-12300):

• Article 1, insofar as it refers to the single registration procedure.
• Article 2, letters f), i) and j); j) only as regards the registration procedures.
• Article 5, which set out the obligations of landlords.
• Article 6, as regards the single registration procedure.
• Articles 8, 9 and 10: the single register, the procedure for registering and requesting the number, and the verification of the number.
• Article 12, letters b) and c).
• Second additional provision, which provided for a voluntary registration number for the rental of a main residence.
• First final provision, in the competence titles that supported the single register.
• And any other mention of the single register in the rest of the royal decree.

There were two other rulings to the same effect. Ruling 629/2026, of 21 May, on the appeal by two tourist apartment associations from Barcelona and Girona, declares null and void articles 2 f) and i), 5, 6, 8, 9, 10 and 12 b); and articles 1, 2 j) and 6 only in their mentions of the Single Register and the registration number. An order of 11 June 2026 corrected it to clarify that article 6 "is not annulled in its entirety": it falls only insofar as it concerns the single register, as in 620/2026. The ruling of 1 June 2026, on the appeal by the Region of Murcia, annuls the same as 620/2026.

Why it annulled it

The Government based the royal decree on four State competences (art. 149.1 of the Constitution). The Supreme Court went through them one by one:

• Public registers (149.1.8.ª). That competence covers civil-law registers. This register does not record contracts or encumbrances on the property: it serves to obtain a number with which to advertise it. According to the ruling, that has to do with the competences of the autonomous communities in housing and, where applicable, tourism.
• Basis and coordination of the economy (149.1.13.ª). The State could set bases or coordination measures, but the royal decree regulated the entire procedure (documents, automatic number, the registrar's assessment, effects) and overlapped with the tourism registers the communities already had.
• Basic conditions of equality (149.1.1.ª). It does not stretch to such a detailed regulation of a register.
• Statistics (149.1.31.ª). It does not support the register, but it does support the sending of data for statistical purposes under article 11.

The ruling adds that Regulation (EU) 2024/1028 does not require the register to be national, and that it does prohibit one and the same accommodation from being subject to more than one registration procedure (art. 4.3.d of the Regulation). Its conclusion: the State "lacks competence" to regulate the single register, but "has competence" to regulate the Digital Single Window for Rentals, the platforms' obligations to transmit data and the transmission of data for statistical purposes.

What remains in force

According to the BOE's consolidated text (last update published on 18 July 2026), the following remain in force, among others:

• Article 7: the Digital Single Window for Rentals. It depends on the Ministry of Housing and Urban Agenda and receives the data that platforms send. The Directorate General for Planning and Evaluation of that ministry is the body that can order the removal of listings for accommodation without a registration number or with an invalid one.
• Article 6: the platforms' obligations, except for its mentions of the single register. They include sending each month the activity data for each accommodation (nights rented and guests), the address and the links to the listings, and removing within 48 hours the listings they are ordered to remove when the competent authority so resolves (the part of that obligation tied to the Single Register number lapsed with the ruling). Orden VAU/653/2025 sets the deadlines and the format for that submission.
• Article 11: statistics. The Single Window sends data on each accommodation every month to the National Statistics Institute, to the regional statistics institutes and to Eurostat.
• Article 12, letters a) and d). The authority for the Single Window is the Ministry of Housing and Urban Agenda; for the sectoral rules on tourist rentals, the relevant autonomous community or town council.

And above the royal decree stands Regulation (EU) 2024/1028, which has applied across the Union since 20 May 2026. It requires Member States that ask platforms for data to have a registration procedure for the accommodation concerned, which can be national, regional or local (art. 4).

Watch out for Orden VAU/1560/2025: it approved the information form that had to be submitted every twelve months under article 10.4, and article 10 has been annulled. As of 16 October 2026, the BOE sheet for that order shows no later reference. If you were asked for that form, check with whoever asked you for it, or with your adviser, whether it is still needed.

What changes depending on your case

• If you have a hotel, aparthotel, hostel or campsite, the Single Register did not apply to you: the royal decree leaves them outside its definition of "unit" (art. 2.b).
• If you rent out a flat or a house to tourists, what is annulled is the State register. Registration in your region's tourism register is not annulled by this ruling; the ruling itself recalls that those registers were created under regional competences.
• If you rent for seasonal periods (for work, study or medical treatment), the ruling points out that the regional tourism registers do not cover those rentals. Ask your region whether it has a procedure for them.
• If you had already obtained the Single Register number, the procedure under which it was issued has been annulled. The ruling does not say what happens to the numbers already assigned or which number each platform will use to replace them: ask before changing anything in your listings.

Whatever your case, the guest registration (parte de viajeros) does not change: it is still mandatory to report your guests' details under Real Decreto 933/2021. The Supreme Court rulings on Real Decreto 1312/2024 do not affect it.

What to check with your region

1. Whether your accommodation has to be entered in your region's tourism (or housing) register, and whether it already is.
2. Which number you have to show in your listings and on the platforms.
3. Whether there are homeowners' association rules you have to comply with before renting: some autonomous communities take this into account in their rules on holiday-use housing (the ruling cites those of Madrid and Asturias).
4. If you had been asked for any Single Register procedure (registration, number or annual form), what happens to it now.

If you manage your bookings in Weko

Weko does not process the registration number: it does not request it for you, does not check that it is valid and does not send data to the Digital Single Window for Rentals. That submission is made by the platforms where you advertise your accommodation.

What Weko does have is a place to store it and show it: in Public profile → House rules, the "Tourist licence no." field. If you fill it in, it appears on your accommodation's public page, in the "House rules" section, as "Licence no.". Enter the number your region tells you to use; Weko does not check its format.
