Fullnægi

Fullnægi is a concept within Danish contract law that translates roughly to "performance" or "fulfillment" of an obligation. It refers to the act by which a debtor satisfies their contractual duty owed to a creditor. For a performance to be considered valid and complete, it must generally be in accordance with the terms of the contract. This includes aspects such as the correct subject matter, quantity, quality, time, and place of performance.

The principle of fullnægi is central to the functioning of contractual relationships. When a party has successfully achieved fullnægi, their obligation is discharged, and they are generally released from further liability concerning that specific contractual duty. Conversely, a failure to achieve fullnægi constitutes a breach of contract, which can give rise to various remedies for the non-breaching party, such as damages, rescission, or specific performance, depending on the circumstances and applicable law. The exact requirements for fullnægi can vary depending on the nature of the obligation, whether it is an obligation to do something, to refrain from doing something, or to pay a sum of money. The concept ensures clarity and predictability in commercial and private agreements.
