Auctions within the meaning of the German Civil Code differ from sales platforms and over-the-counter sales.
An auction within the meaning of Section 156 BGB only exists if the purchase contract is only concluded when the auctioneer accepts the bid. It is precisely this constitutive element that is missing in the case of private treaty sales, M&A auction sales and Ebay-like platforms: There, the contract is created according to the general rules of sales law, usually automatically or by free selection of the seller. The mere “auction character” of a procedure does not replace the legal acceptance of the bid. Anyone referring to an “auction” should therefore make a clear distinction as to whether it is actually an auction — or merely a structured bidding process or a sales platform.
What is an auction within the meaning of the German Civil Code? In this article, we clarify a question that is often underestimated in practice — but is of crucial legal importance: When does an “auction” within the meaning of the German Civil Code actually exist — and when does it not?
We look in particular at section 156 of the German Civil Code (BGB) and distinguish traditional auctions from online auctions such as eBay and from the so-called bidding process.
There are major misunderstandings here — with serious consequences when it comes to pledges of rights, rights to separate satisfaction or insolvency-proof liquidation.
The legal basis: Section 156 BGB.
Section 156 of the German Civil Code is crystal clear:
“In the case of an auction, the contract is only concluded when the bid is accepted.”
This means that it is not the bid that establishes the purchase contract — but the knockdown.
And the knockdown is a declaration of intent by the auctioneer. Without this active knockdown — no contract. That is precisely the central point.
When is it not an auction within the meaning of the BGB?
Many people think that an auction on the Internet is automatically an auction within the meaning of the law. This is wrong. Example: Ebay.
The Federal Court of Justice has repeatedly ruled that eBay auctions are not auctions within the meaning of Section 156 of the German Civil Code (BGB). Why? Because there is no knockdown by a person, but the contract is automatically concluded with the passage of time — via an algorithm. And that is not enough. Because the knockdown must be a declaration of intent by an auctioneer — not a machine.
What about the so-called bidding process?
The so-called bidding process, as it is often known from the real estate sector or from the M&A sector — where it is also referred to as an “auction sale” — is also not an auction within the meaning of the BGB.
Why? Because non-binding purchase price offers are usually obtained there without a clear knockdown by an auctioneer.
The highest bid is often only used as a basis for further negotiations — not as a binding offer that is accepted by knockdown.
In legal terms, this is merely an “invitatio ad offerendum”, i.e. an invitation to submit bids — but not an auction with a knockdown in accordance with section 156 of the German Civil Code (BGB). Even a bidding process with several bids, with deadlines and documentation — remains legally a freehand selection process.
And that is not enough if an auction is required by law.
When is there a genuine auction within the meaning of Section 156 BGB?
Genuine auctions within the meaning of the BGB only exist if:
1. bids are submitted,
2. and the auctioneer — i.e. a person -
3. accepts the bid, i.e. declares acceptance.
This is the case with traditional face-to-face auctions — for example in an auction room with an auctioneer. It is also the case with professional online live auctions, where the auctioneer follows the bidding in real time and makes the winning bid in person — whether by shouting, clicking the mouse or making an electronic declaration. What is important here is that a person must decide whether and to whom to accept the bid. Only then does the contract come into being — in accordance with Section 156 of the German Civil Code (BGB).
Only two forms of auction are recognized by law.
This is legally unambiguous: Only the following two forms are considered auctions within the meaning of the law.
Firstly, the classic face-to-face auction — with a physical auctioneer and verbal knockdown.
Secondly, the online live auction, in which the auctioneer himself knocks down the lot in real time — i.e. no automated auction software, but a real decision by a human being.
All other procedures — i.e. static online auctions, eBay sales, bidding procedures or automated selection formats — are not auctions in the legal sense. They may look like an auction from the outside — but they are not legally sufficient if the law requires an auction. Why is this so important?
Relevance for the realization of creditors.
Quite simply, if you as a creditor have a pledge of rights or a right to separate satisfaction, you may only realize the collateral by public auction, unless a private sale in accordance with Section 1221 BGB is specified. And “public” within the meaning of the law means:
Auction with personal knockdown in accordance with section 156 BGB.
A sale via eBay — or a bidding process — is not sufficient for this.
The consequence: risks of rescission, damages, objections by insolvency administrators, loss of collateral.
Key message:
An auction within the meaning of the German Civil Code only exists if the bid is accepted by a declaration of intent by the auctioneer.
An algorithm, a time lapse or an informal selection process does not replace this award.
The following therefore applies:
Only two formats are legally recognized: face-to-face auctions and online live auctions with a personal hammer price.
Everything else is either a sale by private treaty — or legally simply not an auction.
If you, as a creditor, want to sell your property securely and in compliance with the law, make sure that a public bid is accepted by an auctioneer — whether in person or live online.
