termijnwijziging

Termijnwijziging is a Dutch term that describes the modification of a specified period or term in a contract, agreement, or legal context. The word combines *termijn* (term, period) and *wijziging* (change). It is used in many areas of Dutch law, most commonly in employment contracts, lease agreements, public procurement, and certain civil obligations.

In employment law, an employer may propose a termijnwijziging to change the duration of a fixed‑term contract, to extend or shorten a probationary period, or to shift the start or end date of a working arrangement. The employee must consent to such a modification, and the change is documented in an amendment or a new written contract. Courts require that the parties act in good faith and that the new term be reasonable and not create an undue disadvantage.

For lease agreements, tenants or landlords may negotiate a termijnwijziging to alter the lease duration or the renewal period. The amendment must follow the same formalities as the original contract, including written confirmation and, where relevant, notification to municipal authorities.

In public procurement, a termijnwijziging can adjust deadlines for submission of proposals, evaluation periods, or contract execution dates. The procurement authorities must publish the change and provide affected bidders with appropriate notice to remain compliant with competition rules.

Overall, a termijnwijziging reflects a consensual change to a time-bound obligation, governed by the principles of contract law and the specific regulatory framework that applies to the type of agreement.
