Retention of title (also known as reservation of ownership) is a contractual mechanism whereby the seller retains ownership of goods until the purchase price has been fully paid. It is a widely used tool in both domestic and international trade to mitigate credit risk and protect sellers against buyer default. Although the concept of retention of title is broadly recognised, its legal treatment, enforceability, and practical implications vary significantly between legal systems. These differences are particularly evident in areas such as the recognition of ownership rights, the enforceability of clauses against third parties, and the treatment of goods in the event of the buyer’s insolvency or bankruptcy. This guide provides a practical overview of retention of title clauses and their regulation across multiple jurisdictions, addressing recurring key questions, such as
How retention of title is regulated under national law
The legal status of goods subject to retention of title in bankruptcy proceedings
The formal requirements for an enforceable retention of title clause
The possibility of including retention of title in framework or supply agreements
The registration or security mechanisms available to strengthen the seller’s position

Does the concept of retention of title exist in Slovenia?
Yes, the concept of retention of title (pridržek lastninske pravice) exists under Slovenian law.
A retention of title is a specific contractual clause, typically included in a sales agreement involving movable property. Under this clause, the seller retains ownership of the goods until the purchase price is paid in full, even if possession has already transferred to the buyer. During this time, the buyer assumes the risk of accidental loss or destruction but may use and enjoy the goods. The clause serves as a form of security for the seller.
However, issues can arise if the buyer resells or transforms the goods. In such cases, the original seller’s ownership may be extinguished despite the retention of title, as the buyer acquires title to the newly created item. To address various risks, Slovenian law recognizes several variations of the retention of title, including the extended retention of title and the retention with a transformation clause.
Extended retention of title: If the buyer resells the goods to a third party, the original seller acquires a lien over the buyer’s claim against the third party.
Retention with a transformation clause: If the goods are transformed, ownership of the new item passes to the original seller (contrary to the general rule where the buyer becomes the owner).
While retention of title clauses are commonly included in the seller’s general terms and conditions, caution is needed. An agreement that includes such a clause is only effective between the parties (inter partes) unless the buyer’s signature is notarised. Without notarisation, the clause has no effect against third parties (erga omnes), including creditors or in insolvency proceedings.
Under private international law, rights in rem (i.e. ownership rights) are governed by the law of the country where the property is located (lex rei sitae). Therefore, if the movable property is located in another jurisdiction, the legal effectiveness of the retention clause against third parties is determined by the law of that country.
Can the retention of title be agreed upon in a framework contract, or must the goods be specifically identified?
Retention of title clauses may be included in framework agreements and/or in the general terms and conditions of sale. For the clause to be valid between the parties, the goods must be described with sufficient precision.
For the clause to be enforceable against third parties, in addition to adequate specification of the goods, formal requirements such as notarisation of the buyer’s signature must also be met.
What happens to goods subject to retention of title when the buyer enters bankruptcy proceedings?
To ensure that a retention of title clause is enforceable against third parties in bankruptcy or enforcement proceedings, certain formalities must be satisfied in addition to the general requirements (e.g. the clause must be permissible, and the goods must be clearly defined or identifiable).
The key formality is notarisation of the buyer’s signature on the agreement. This notarisation may be performed by either a Slovenian or a foreign notary.
Only a properly formalised agreement will have effect against third parties, such as:
In enforcement proceedings against the buyer, the seller retains a third-party claim to the goods.
In bankruptcy, the seller has the right to separate recovery or set-off of the goods.
What formalities are required for a clause of retention of title to take effect in Slovenia?
No specific formalities are required for the clause to be effective between the contracting parties.
However, if the clause is intended to be effective vis-à-vis third parties—especially in execution or insolvency situations—the buyer’s signature must be notarised. Without notarisation, the retention of title clause will not be enforceable against third parties.
