Judicial auctions: buying property in Barcelona through a subasta
Judicial auctions can offer below-market purchases, but without an interior viewing and with potential eviction risks. We examine the changes introduced in 2025.
A judicial auction (subasta judicial) is a court-ordered property sale, usually within enforcement proceedings over an owner's unpaid debt. It offers investors a lawful route to buying below market value, but with risks absent from an ordinary purchase through an agency.
What changed with the 2025 reform
Ley Orgánica 1/2025 took effect on 3 April 2025, increasing the standard auction participation deposit from 5% to 20% of the lot's assessed value. Some auctions currently running were opened before that date and still require a 5% deposit. The applicable rate depends on when enforcement proceedings began, rather than the auction date itself. Before paying a deposit, establish which rules govern the particular lot: this directly affects the amount that must be tied up to participate.
The reform made judicial auctions through the BOE Portal de Subastas a more transparent and central sales mechanism, aiming to broaden participation and make the procedure more public.
How the purchase works
Auctions take place electronically on the BOE portal. After winning, the buyer has 20 working days to pay the entire balance; instalments are not available. A separate, extrajudicial notarial auction is possible only where expressly provided for in the mortgage deed (escritura), and is conducted by a notary rather than a court. These are different procedures with different rules and must not be confused.
Risks beyond an ordinary transaction
The main limitation of a subasta is that the buyer can almost never inspect the interior before bidding. Decisions are made from documents and the building's exterior. Inside, anything may await, from a need for complete renovation to unauthorised alterations.
The second risk concerns occupants. The flat may be occupied by the former owner, a tenant or squatters, and obtaining vacant possession after purchase is a separate procedure that is not always quick.
The third risk is familiar from any purchase: encumbrances. An auction does not remove the need to check cargas and registry history just as thoroughly as in an ordinary transaction. See checking encumbrances and the due diligence checklist. Some debts and mortgages may remain attached to the property after sale, depending on their priority.
When it makes sense
A subasta suits an investor willing to accept uncertainty in exchange for a below-market price, with legal support to examine the lot before depositing funds and handle any eviction after winning. It is not a route for an inexperienced first purchase: misjudging condition or missing an encumbrance can cost more than the price saving.

Questions and answers
Can the buyer withdraw after winning an auction?
No. Once the lot is awarded, the buyer is obliged to pay. The deposit exists to secure that obligation, and withdrawal means losing it.
What happens if the balance is not paid within 20 working days?
The buyer forfeits the deposit, and the court may award the property to the next bidder or order another auction.
Does an extrajudicial notarial auction carry different risks?
The legal nature of the risks—lack of inspection, encumbrances and possible occupants—is the same. The differences concern who conducts the procedure and the requirement for it to be expressly provided for in the mortgage deed.
