Term and meaning of the component in law
The term ‘Bestandteil’ (component) holds decisive importance in German law, particularly in relation to objects, real estate, and ownership relations. While the term is often used synonymously with ‘part’ in everyday language, the German Civil Code (BGB) regulates very precisely what is to be understood by a component and what legal consequences arise from this.
Definition and distinction
Definition according to § 93 BGB
According to § 93 BGB, components of an object are ‘all things that cannot be separated from one another without either being destroyed or altered in their essence.’ Thus, a component always exists when an object is so connected with another that separation is not possible, or only possible with considerable destruction or alteration.
Distinction from accessories (§ 97 BGB)
An important distinction in property law concerns the differentiation from so-called accessories (§ 97 BGB): Accessories are movable items that, without being components, are intended to serve the economic purpose of the principal object and stand in a spatial relationship to it. Components, in contrast, are inseparably connected with the principal object.
Essential components (§ 94 BGB)
Another relevant category is the essential components of an object. According to § 94 BGB, essential components of a property include, among others, buildings that are permanently attached to the ground, as well as natural products of the property as long as they are rooted in the soil (e.g., trees and plants).
Legal consequences of component status
Legal relationship between the principal object and the component
As components according to the BGB cannot be treated independently in legal terms, a component always shares the legal fate of the principal object. This means that legal dispositions or encumbrances regarding individual components are not possible (§ 93 sentence 2 BGB). Thus, the owner of an item may only dispose of its components together with the principal object.
Transfer, encumbrance, and disposition
The legal lack of independence of components particularly affects the possibilities of transfer and encumbrance. For example, if a property is sold, the essential components, such as buildings erected upon it, automatically transfer to the purchaser with the vesting of ownership in the property.
Separation of components
A separation of components is only possible if this occurs without destruction or material alteration. Through such separation, components (if viable on their own) can regain their status as independent things and thus be subject to separate property rights.
Components in real estate and buildings
Real estate components
Essential components of a property are, in particular, all items firmly attached to the land, for example buildings, enclosures, or permanently installed systems. According to § 94 para. 1 BGB, essential components of a property also include firmly affixed items such as doors, windows, or heating systems.
Loss of component status
Once a component is separated from the property, it loses its status as a component and can be treated as an independent movable item. This is the case, for example, when windows are removed from a building and sold separately.
Components and pseudo-components (§ 95 BGB)
Concept of pseudo-component
§ 95 BGB regulates so-called pseudo-components. These are items which are attached to a property or building only for a temporary purpose. Pseudo-components remain legally independent and do not become part of the property as long as they are intended and suitable to be removed according to their purpose (e.g., exhibition pavilions, trade fair stands, construction huts).
Components in the context of acquisition of ownership
Significance for acquisition of ownership
The inseparability of components and the principal object is particularly important in the acquisition of ownership: Ownership of the principal object automatically extends to its components. An exception applies to pseudo-components, whose ownership can be acquired or disposed of independently.
Relevance for security transfer of title and mortgage
In connection with security transfer of title and mortgages, components are deemed part of the encumbered object. For example, a property together with its permanently installed components can serve as the basis for a mortgage.
Special cases and practical areas of application
Accessories versus components in case law
In practice, questions of classification often arise, for example with machines in industrial facilities or fixtures in rented properties. Here, in each individual case, the degree of connection and the economic context are decisive in determining whether an item is to be considered a component or an accessory.
Multiple owners and components
The law generally does not provide for different ownership rights to exist in the principal object and its components. In mixed-use buildings, subsequent additions, or in the context of development models, this can lead to complex legal issues.
Components in international law
While the doctrine of inseparability dominates in German law, diverging regulations exist in other legal systems. The treatment of components and their separation also plays a significant role in international real estate transactions.
Significance in property law and for contract drafting
The definition of components is of substantial relevance for drafting contracts in real estate and commercial law. Clear contractual arrangements and precise identification of associated components are necessary in order to avoid disputes.

Summary
The term component is associated with far-reaching legal consequences under German law. Its definition and the distinction from accessories, pseudo-components, and essential components are decisive in determining how property rights, transfers, and encumbrances are to be handled legally. Understanding the legal significance of components is therefore essential for property law and numerous practical areas of application.
Frequently asked questions
When does a component exist in the legal sense?
A component in the legal sense exists in accordance with § 93 BGB if an item is connected to a principal object in such a way that it cannot be separated without destruction or significant alteration. The determining factor is whether a physical connection exists that creates a permanent unity. The prevailing public perception is decisive: Would an average observer assume that the item in question is firmly part of the principal object? Examples include doors or windows in a house. The connection must be so close that, economically or technically, separation is neither possible nor customary. It is irrelevant whether the connection could easily be undone, as long as the separation would cause damage or destruction to the principal object or the part. The ownership relationship is also irrelevant—the legal treatment depends solely on the physical relationship between the objects.
What are the legal consequences of classification as a component?
If an object is legally classified as a component of a principal object, it particularly means that it cannot independently be the subject of rights or legal transactions. Ownership of the component is inseparably connected with ownership of the principal object; there are no separate ownership rights to the component (§ 94 para. 1 sentence 2 BGB). All proprietary rights, such as mortgages or land charges, also extend to the components. When the principal object is sold, the components are automatically transferred together, with no need for a separate agreement. A contractually agreed retention of title on the component loses its effect upon joining. Components are also always subject to the legal fate of the principal object in security law and enforcement proceedings.
What is the difference between essential and simple components?
The law distinguishes between so-called essential components (§ 94 BGB) and simple components (§ 93 BGB). A component is considered essential if its separation would result in the destruction or substantial alteration of the principal object or the component itself. Simple components are less closely connected to the principal object; their separation would result in changes, but not significant impairment. Essential components can never independently be the subject of special rights, whereas this may be possible for simple components under certain circumstances. The distinction is particularly relevant in practice for buildings, machinery, and vehicles, and is often the subject of legal disputes.
How is it determined whether a connection between two items is so close that a component exists?
The determination of whether an object has become a component of another is made according to objective criteria, based on external circumstances and common public perception. The decisive factor is the degree of connection—factors such as construction method, technical fixation, purpose of the connection, and degree of economic dependency must be taken into account. Case law emphasizes the need to focus on common practice and perspective: For example, if a built-in kitchen is individually fitted, this indicates a component; in contrast, standardized, removable furniture does not. The intent of the parties may also be additionally considered in the assessment, but only holds subordinate importance compared to the actual condition.
What special regulations exist for components in real estate and buildings?
For real estate and buildings, special regulations are provided in §§ 94 and 95 BGB. According to § 94 BGB, items that are firmly attached to land, such as buildings and the items incorporated in their construction (e.g., heating systems, staircases), are essential components of the property. They therefore follow the legal fate of the real estate. § 95 BGB, on the other hand, establishes an exception for so-called pseudo-components: If items are connected to the land only for a temporary purpose, they are not considered components. This is relevant for instance for construction containers or trade fair stands that are installed for a limited period. These special regulations serve to make the transfer of real estate and legal assignment clear and practical.
What does the classification as a component mean for security transfers and retention of title?
In the event of security transfer of title and retention of title, the legal classification as a component has significant effects. If a part delivered under retention of title is firmly incorporated into a principal object—for example, installing a heating system into a building—the title of the conditional seller expires: the part becomes the property of the real estate owner as a component. An isolated security transfer of a component is no longer legally possible once the fixed connection exists; the secured party merely has a possible contractual compensation claim. These principles serve to protect the legal traffic and ensure clear allocation of ownership rights.
Are accessories and components treated differently in law?
Yes, accessories (§ 97 BGB) and components are treated differently in German property law. Accessories are movable items that, without being components, are intended to serve the economic purpose of the principal object and are permanently allocated to it (e.g., barn equipment for a farm). Unlike components, accessories can be separately transferred or encumbered and remain legally independent. While components inseparably follow the legal fate of the principal object, there are different rules for accessories, such as the principle of accessory transfer in real estate purchases (§ 926 BGB). This distinction is particularly relevant for real estate and chattel law as well as in the context of security rights.
