Retention of title means that ownership of a delivered item is not transferred until consideration has been given. The consideration usually consists of payment of the agreed purchase price. Retention of title is mainly used in purchase agreements for the sale of goods, but can also be applied in an exchange agreement. In contrast to the right of reclamation, retention of title must be agreed. Indeed, the right of retention of title is not a legal competence, but a contractual competence which must be agreed upon. The retention of title is regulated by law in Article 3:92 of the Civil Code (BW).
