A couple of heirs in disagreement over the division of a family home, an owner pressured by legal proceedings, or simply a seller looking to get the best price through competition: selling a house at auction addresses very concrete situations. Behind this unique term lie legally distinct procedures, with rules, timelines, and fees that vary greatly depending on the type of sale chosen.
Notarial, judicial, or interactive sale: three procedures not to be confused
We often refer to “real estate auctions” as a single entity. In practice, each format follows different rules and protections. A seller who confuses these procedures risks finding themselves in a timeline they cannot control.
The voluntary notarial sale is freely chosen by the owner. The notary organizes the publicity, sets a starting price, and conducts the auction session. The seller retains some control over the timeline but must accept the outcome of the auction.
The judicial sale, on the other hand, occurs under constraint: foreclosure, liquidation, or the exit from joint ownership ordered by a judge. Here, it is a lawyer who brings the bids to court. The additional costs are often higher, and the seller has almost no power over the process.
The interactive sale represents a third case, often misunderstood. The interactive sale is not an auction: the seller retains the choice of the accepted offer, and the transaction generally continues with a traditional compromise, with the usual protections for the buyer. It resembles an online bidding process more than a sales room. When considering support from Direct Immobilier, this distinction between formats is clarified from the outset to guide the project toward the appropriate procedure.
Setting a price for a house at auction: what the seller should anticipate
The starting price attracts the attention of buyers, but it also creates a trap for the seller who might confuse it with an appraisal. The starting price is neither a guaranteed discount nor a reliable floor price. In notarial sales, an attractive amount is intentionally set to stimulate competition on the day of the session.
The final price depends entirely on the dynamics between bidders. With few participants, the property may sell for a disappointing amount. With strong competition, the actual amount obtained can match or even exceed market prices.
As a seller, one must calibrate the starting price with the notary, taking into account several parameters:
- The actual condition of the property and any necessary work, which directly influences the number of bidders willing to participate
- The location and tension of the local market, as a property situated in a sought-after area naturally generates more competition
- The timing of the sale, as certain times of the year attract fewer buyers and reduce bidding dynamics
An experienced notary adjusts the starting price to increase participation without undervaluing the property. Feedback on this point varies by geographic area, but the principle remains the same: the more bidders there are, the better chance the seller has of obtaining a good price.
Overbidding and post-auction timeline: the actual calendar of a sale
The auction session is not the final point of the sale. For certain notarial auctions, anyone can propose at least 10% more within ten days following the auction. This overbidding mechanism then puts the property back on sale during a new session.
For the seller, this is a double-edged sword. On one hand, overbidding can drive up the price. On the other hand, it delays the finalization of the transaction and prolongs uncertainty, sometimes for several weeks.
In judicial sales, the timelines extend even further. Between the court’s decision, the legal publication, the auction session, and the judgment of adjudication, the total timeline can stretch over several months. The seller (or co-owner) must factor this duration into their planning, especially if they have a parallel purchase project.
Exiting joint ownership through auctions: when the auction becomes the only solution
Exiting joint ownership represents a common use case but is rarely addressed from the seller’s perspective. When heirs or ex-spouses cannot agree on the fate of a property, one of them can ask the judge to order the sale by auction.
This procedure does not eliminate the prior notarial phase or judicial oversight. The notary prepares a liquidation statement, the court authorizes the sale, and then the auction proceeds according to the rules of judicial sale. The proceeds are then distributed among the co-owners according to their shares.
Costs are borne by the co-owners and are deducted from the sale price. This includes:
- Legal advertising and mandatory diagnostics, which remain the same as for a traditional sale
- Lawyer’s fees, mandatory for bringing bids before the judicial court
- Notary’s fees for the liquidation and distribution of the price among the parties
A family disagreement does not indefinitely block the sale of a jointly owned property. The judicial procedure offers a way out, but it imposes a rigid framework where none of the co-owners controls the final price.
Actual costs for the seller during a real estate auction
In a traditional sale, the seller mainly pays for diagnostics and their share of notary fees. In an auction, the cost structure changes significantly.
In a voluntary notarial auction, the seller bears the costs of publicity (legal notices, catalog from the chamber of notaries) and the fees of the organizing notary. These costs are deducted from the auction price.
In a judicial sale, costs increase: lawyer fees, procedural costs, publication in the real estate file. The seller constrained by a foreclosure sees these amounts directly deducted from the sale proceeds, which reduces the amount they recover.
The buyer, for their part, pays transfer taxes and specific fees for the auction, but this does not exempt the seller from their own charges. Before committing to a voluntary auction, comparing the net cost after fees with a traditional sale allows for verifying that the format is truly advantageous for their particular case.
