A unilateral amendment clause gives one party (usually the licensor) the right to modify the terms of a licensing agreement without needing approval from the other party. This means that essential terms—such as fees, scope of use, or even termination rights—can be changed at any time, often with little or no notice.
While some flexibility is necessary in long-term contracts, these clauses can create significant imbalances and expose licensees to unexpected changes that may not be in their best interests.
