sopimusperusteisten

Sopimusperusteisten is a Finnish inflected form of the adjective sopimusperusteinen, meaning contract-based or based on an agreement. The term describes entities, rights, obligations, or rules that derive from a contract or agreement rather than directly from statute or regulation. It is commonly used in legal, administrative, and employment contexts to distinguish arrangements that are defined by an agreement between parties from those set by law.

In Finnish, adjectives decline to agree with the noun they modify in number and case. Sopimusperusteisten is the genitive plural form, typically used with a noun in genitive plural, for example sopimusperusteisten ehtojen mukaan, meaning according to the contract-based terms. Other common constructions include phrases like sopimusperusteisten etuuksien piirissä (within the circle of contract-based benefits) or sopimusperusteisten velvoitteiden täyttämisestä (fulfilling contract-based obligations). These forms emphasize that the relevant provisions originate from an agreement rather than statutory regulation.

The term contrasts with lakiperusteisiin or lainsäädäntöön perustuvia, which describe something governed directly by law. Sopimusperusteisten usage highlights the role of negotiated or agreed-upon terms in determining rights, duties, or entitlements, such as in collective agreements, service contracts, or partnership arrangements. While the concept is widely applicable, it is most frequent in contexts where flexibility, negotiation, and party-specific terms are central.
