🇪🇸Spanish Subastas BOE: How to Bid and Win
How Spanish judicial auctions work
Spanish judicial auctions are conducted online through the official portal subastas.boe.es, operated by the Agencia Estatal Boletín Oficial del Estado. All auctions follow a standardized 20-day online bidding period. Properties come from judicial proceedings (courts), tax collection (Agencia Tributaria), and social security enforcement. The system is fully digital — no in-person attendance required.
The bidding process
To participate, you need a digital certificate (certificado digital) or DNI electrónico. Register on subastas.boe.es and deposit 5% of the asset's value (consignación) via bank transfer. Bidding runs for exactly 20 calendar days. You can place multiple bids, and all bids are binding — you cannot retract a bid once placed. The highest bidder wins, but the court can reject bids below certain thresholds.
Minimum bid thresholds
For residential properties (vivienda habitual), the minimum acceptable bid is 70% of the appraised value. For other properties, it's 50%. If no bid reaches the minimum, the creditor has the option to accept the highest bid or request a new auction. In practice, many properties sell at or near the minimum threshold, offering 30-50% discounts from appraised values.
After winning
The winning bidder must pay the remaining balance (95%) within 20 working days. The court issues an auto de adjudicación (court decree of award), which is registered at the Registro de la Propiedad. Transfer taxes (ITP) of 6-10% apply depending on the autonomous community. Existing tenants may have occupancy rights, and the buyer is responsible for any outstanding community fees (gastos de comunidad).
