A real estate auction refers to a procedure where a property is awarded to the highest bidder, according to rules set by law or by a public officer. The final price does not result from a private negotiation between seller and buyer, but from the public confrontation of bids on the day of the session. This mechanism, called adjudication, immediately binds the buyer from the last bid, with no possibility of withdrawal comparable to that of a traditional sale.
Overbidding and occupation: two risks that the adjudication price does not reveal
Most guides on real estate auctions detail the three channels (judicial, notarial, state) and the procedure of the session. Two points deserve more technical attention, as they modify the actual budget and timeline of the operation.
The first concerns overbidding after judicial adjudication. Within ten days following the announcement of the adjudication, a third party can submit an overbid with a minimum increase of 10%. A new hearing is then scheduled. The initial winning bidder is therefore not the definitive owner until this period has elapsed.
The second concerns the occupation of the property. A property sold at a judicial auction may be occupied by the former owner, a tenant with a lease, or an occupant without right or title. The adjudication judgment serves as an eviction title, but the actual procedure (notice to vacate, recourse to the enforcement officer, legal deadlines) can take several months.
This parameter transforms an apparently quick purchase into a lengthy operation if the occupation has not been anticipated. Before bidding, it is essential to carefully read the sales conditions document to identify the exact rental situation of the property.

Actual budget of a real estate auction: costs beyond the price
Simulating one’s budget by limiting it to the adjudication price is a common mistake. Additional fees can represent a significant part of the total cost, far exceeding the notary fees of a traditional transaction.
Here are the main items to include in the calculation:
- Transfer taxes (property publicity tax and departmental levies), identical to those of a traditional sale.
- The real estate security contribution, due upon the publication of the adjudication judgment at the property publicity service.
- The attorney’s fees (mandatory in judicial sales) and any notary fees for notarial sales.
- Preliminary costs incurred by the pursuing creditor: diagnostics, publication, mortgage statements. These costs are borne by the winning bidder and are listed in the sales conditions document.
A serious candidate adds these items before the session and sets their maximum bid accordingly, not at the last moment in the room.
Notarial interactive sale: a false twin of adjudication
In recent years, notaries have been offering so-called “interactive” online sales. The terminology can be confusing, but the interactive sale remains an amicable sale. The seller retains the right to accept or reject the best offer, and the final deed is drafted like a traditional sale. No irrevocable commitment binds the bidder in the same way as a judicial adjudication. Confusing the two formats can lead to underestimating one’s obligations in one case or overestimating one’s guarantees in the other.
Sales conditions document: this document conditions everything else
The sales conditions document (sometimes called the specifications) is the central legal document of a real estate auction. It sets the starting price, occupancy conditions, easements, technical diagnostics, and payment terms.
The winning bidder is deemed to have acknowledged the entirety of the document. No subsequent dispute based on a clause that was not read is admissible. Two points deserve particularly careful reading:
The first is the clause regarding hidden defects. In the majority of judicial sales, the guarantee of hidden defects is excluded. The buyer acquires the property as is, with no recourse against the seized seller.
The second is the detail of preliminary costs. Their exact amount is stated in the document. Not including them in the budget amounts to bidding blindly.

Attorney in judicial sale: a requirement, not an option
To bid at a judicial auction in court, representation by an attorney is mandatory. The buyer does not bid themselves: it is the attorney who raises their hand in the courtroom, under the client’s instructions.
The choice of attorney is not trivial. A practitioner familiar with real estate adjudications knows the pace of the hearings, knows when to push and when to stop. They also check in advance the compliance of the file (deposit check, identification documents, proof of financing).
Financing and deposit
Before the session, the buyer must submit a deposit check whose amount varies depending on the type of sale. In notarial sales, this bank check generally represents a fraction of the starting price. In judicial sales, the amount is set by the sales conditions document.
Obtaining a bank financing agreement before the hearing is strongly recommended. Unlike a traditional sale, there is no suspensive condition for a loan in judicial adjudication. If the winning bidder cannot pay, they risk a procedure for frivolous bidding and losing their deposit.
Assets confiscated by the justice system: a auction sales channel to watch
The Agrasc (Agency for the Management and Recovery of Seized and Confiscated Assets) constitutes a distinct circuit. In 2025, this agency sold 188 properties for a total amount of 40 million euros. These properties come from seizures or criminal confiscations, not voluntary sales.
The starting prices are sometimes discounted, but the acquisition conditions remain subject to the same procedural rules. This channel is still little frequented by individuals, which can reduce competition during the auctions.
Buying at real estate auctions relies on extensive documentary and financial preparation that precedes the day of the sale. The sales conditions document, the complete calculation of costs, and the verification of the property’s occupation form the foundation of a controlled acquisition. Without this preparation, the risk of paying more than in a traditional sale, for a property whose condition and possession timeline are not controlled, becomes very real.
