A unilateral amendment clause in an NDA gives one party—usually the drafter—the right to modify the agreement’s terms at any time, often without notifying or obtaining approval from the other party. This means the rules governing confidentiality, permitted disclosures, or even the duration of the NDA could change without your knowledge or consent.
Such clauses are typically worded as: "The Disclosing Party may amend this Agreement at any time by providing notice to the Recipient." In some cases, even notice isn’t required.
