The judgment of 21 May 2026 voids the national registration number. Here is what falls away and what remains in force.
In its judgment 620/2026 of 21 May 2026, the Spanish Supreme Court annulled the procedure for the Single Short-Term Rental Registry set out in Royal Decree 1312/2024, which had been in force since 1 July 2025.
The reason: the Court held that the State lacks the competence to create a national registry overlapping the autonomous-region registries that already govern tourist rentals — a matter reserved to the regions.
What falls away: the obligation to obtain and maintain the national single registration number. Those who paid the fee may claim a refund from the relevant registry, providing the invoices.
What remains in force: the Single Digital Rental Gateway and the platforms' data-transmission duties are not affected by the annulment. Above all, the regional registries regain their central role — in Andalusia, the Andalusian Tourism Registry.
What now? Some uncertainty remains over which identifier to use for reporting to platforms, especially with the EU Regulation already in force. If you own an apartment in Marbella, we recommend reviewing your regional registry status and not deregistering anything without advice.
