Tribunal Supremo

Spain's highest court of ordinary jurisdiction, ruling on civil, criminal, administrative and social matters.

Registration of Spanish short lets has sat with the seventeen regions since the Tribunal Supremo voided The National registration number on 21 May 2026 in STS 620/2026; Congress's rejection of two rental decrees on 2 October left that split untouched.

Background

The Tribunal Supremo is Spain's highest court in every branch of law except constitutional guarantees. Established under the Cádiz Constitution of 1812 and seated in Madrid, it sits above the civil, criminal, contentious-administrative, social and military chambers of The National judiciary, and its case law binds every lower court. Disputes over the constitutionality of laws, including clashes between central and regional powers in legislation, go instead to the separate Tribunal Constitucional.

Its contentious-administrative chamber is the main forum for challenges to government decrees and ministerial regulation, which brings it cases on energy, Labour, tax, housing and consumer protection. Tenants WHO filed rent-freeze extension requests before Congress rejected the extension on 28 April 2026 must wait for a ruling from this court or the Tribunal Constitucional to learn whether those filings bind their landlords.

Its most consequential recent ruling, STS 620/2026, moved short-let registration to the seventeen autonomous communities while leaving civil lease law where the Constitution puts it. That split decides which regions can write their own rental contracts law.

Key Issues
Rental registry

The court voided the national registration number

In STS 620/2026, handed down on 21 May 2026, the Court partially annulled Royal Decree 1312/2024 and struck out the mandatory national registration number for short lets. It held that registry rules belong to the autonomous communities, a challenge brought by the Valencian regional government.

The judgment drew a second line that now shapes Spanish housing law. Registration became a regional matter, but civil lease law stayed reserved to the state under Article 149.1.8 of the Constitution, except in the six communities with their own historic civil law. That is why Navarra could legislate room rentals directly in July while ordinary regions could not. After 2 October, when Congress sank two rental decrees, the Court's division of powers is the main fixed point left in Spain's short-let rules.

Common Questions

STS 620/2026 splits registration from lease law

Why did the Canary Islands pass its own tourist-municipality law instead of a national one?
The Tribunal Supremo's STS 620/2026 ruling voided Spain's national STR registration number for overstepping central competence into regional territory. The Canary Islands' 8 July 2026 tourist-municipality law legislates directly at the autonomous-community level, avoiding that same competence challenge.Source: nomads-and-communities topic context
Did Spain's Supreme Court give civil lease law power to all 17 regions?
No. STS 620/2026 devolved short-term-rental registration competence to all 17 autonomous communities, but civil lease law remains reserved to the six foral communities under Article 149.1.8 of the Constitution.Source: Tribunal Supremo
Does STS 620/2026 affect Spain's STR listing-accuracy obligations?
No. The ruling voided only The National registration number requirement. The digital single-window and data-transmission obligations under EU Regulation 2024/1028 were upheld, meaning platforms must still verify listing accuracy.Source: Lowdown
