Mittetäitvil

Mittetäitvil is a term that appears in Finnish-language discussions about contracts to describe a party that does not fully satisfy all contractual obligations, but does fulfill a portion of them. It is used as a descriptive, theoretical concept rather than a formal, codified legal standard. In practice, the idea focuses on partial compliance and invites consideration of how much of the contract’s purpose is achieved and what remedies are appropriate for the remainder.

The concept is closely related to, but distinct from, breach. Unlike a complete failure to perform, mittetäitvil highlights that some performance has occurred and that the remaining deficit may be addressed through remedies such as proportionate payment, remediation, or damages. It aligns loosely with the notion of substantial or partial performance found in various legal systems, but it is not a standardized term in most codes and is more common in academic or discourse contexts.

Usage and context vary. Mittetäitvil is primarily used in discussions about procurement, project delivery, or ongoing contracts where performances are uneven or staged. In everyday Finnish legal language, more established terms like osittainen suoritus (partial performance) or substantial performance are typically preferred for precise analysis. Mittetäitvil serves as a shorthand to frame debates about risk allocation, good faith, and remedies when a party’s performance falls short of the full contractual ideal without constituting an outright breach.
