Retention of Title in Machinery Purchases — What It Means

You sign a contract for a used CNC milling machine at EUR 55,000. You pay EUR 20,000 upfront, the rest in three installments. The machine is on your shop floor, your team is producing on it. But legally, it is not yours. Until you pay the last euro, the seller remains the owner. This is Eigentumsvorbehalt — retention of title, a standard clause in German machinery trade that carries significant consequences for Polish buyers.

Legal basis — Section 449 BGB

Retention of title is governed by Section 449 of the German Civil Code (BGB). It allows the seller to retain ownership of the sold goods until the purchase price is paid in full. The buyer receives possession — and may use the machine — but does not hold title.

Core principles:
- Ownership transfers only upon full payment
- The buyer holds an expectant right (Anwartschaftsrecht) — economically attributable but not full ownership
- In case of payment default: the seller can demand return of the machine
- The retention must be agreed before or at the time of handover

In practice, the retention of title clause appears in the seller's AGB or directly in the purchase contract.

Three variants — from simple to extended

1. Simple retention of title (einfacher Eigentumsvorbehalt)
Ownership remains with the seller until the purchase price for this specific machine is fully paid. Standard in B2B trade. Predictable and generally unproblematic.

2. Extended retention of title (erweiterter Eigentumsvorbehalt)
Ownership transfers only when all outstanding claims of the seller against the buyer are settled — not just for this machine, but from the entire business relationship. If the buyer has an unpaid spare parts invoice from six months ago, the EUR 55,000 machine formally still belongs to the seller.

3. Prolonged retention of title (verlängerter Eigentumsvorbehalt)
The seller claims rights over products manufactured with the machine (processing clause) or over the resale proceeds (advance assignment of claims). Less common in the machinery trade but possible in large transactions with deferred payment terms.

Variants 1 and 2 dominate in machine sales. Variant 3 requires an individual agreement and is often unenforceable in standard terms (Section 307 BGB — unreasonable disadvantage).

Practical scenarios

Scenario 1: Installment default.
The buyer has paid EUR 40,000 of EUR 55,000. The EUR 15,000 installment is 30 days overdue. The seller sets a Nachfrist (grace period). After expiry: the seller may withdraw from the contract and demand return of the machine. The EUR 40,000 already paid? The seller deducts a usage fee and depreciation. The buyer gets the difference — but must claim it.

Scenario 2: Buyer's insolvency.
A machine under retention of title does not enter the insolvency estate. The seller can demand separation (Aussonderung) under Section 47 InsO. The insolvency administrator has no right to liquidate it. For the seller, retention of title is an effective credit security device.

Scenario 3: Enforcement against the buyer.
If a creditor enforces against the buyer's assets, the seller can file a third-party objection (Drittwiderspruchsklage under Section 771 ZPO) to exclude the machine from enforcement.

Scenario 4: Machine permanently installed.
The machine has been concreted into the factory floor. Does the seller still have a return claim? In principle, yes — but the machine may have become an essential component of the property (Section 946 BGB). In that case, the retention of title extinguishes. The distinction depends on the specific circumstances and is often disputed.

Conflict of laws — what applies in Poland

Once the machine is delivered to Poland, the proprietary protection of the retention of title is governed by Polish property law (lex rei sitae). Under Article 589 of the Polish Civil Code:

• Retention of title must have a certified date (data pewna) — for example through notarial authentication — to be effective against third parties
• A simple retention clause in AGB without a certified date protects the seller only between the two parties, not against a Polish bailiff or insolvency administrator

This is a significant asymmetry: a clause that is fully effective in Germany may be unenforceable against third parties in Poland. Many German sellers are unaware of this.

Recommendations for both sides

For the seller:
- Use simple retention of title as minimum protection
- For installment sales: verify whether the retention is effective against third parties in the destination country (Poland)
- For transactions exceeding EUR 50,000: consider notarial authentication of the purchase contract for enforceability in Poland

For the buyer:
- Check whether simple or extended retention applies
- For installment payments: negotiate a clear payment schedule with a defined point of ownership transfer
- Be aware: under retention of title, you cannot use the machine as collateral (e.g., for leasing refinancing)

How Hutnia manages the retention of title process

As a procurement agent, Hutnia reviews the retention of title clause before contract signing. We identify whether simple, extended, or prolonged retention is intended, negotiate the payment schedule, and inform the buyer about the legal consequences in both jurisdictions.

For transactions exceeding EUR 50,000, we recommend involving a Polish attorney regarding the certified date requirement — to ensure the retention of title remains enforceable against third parties after the machine arrives in Poland.
