Legal Definition
In a legal context, 'adverse' refers to an unfavorable or detrimental situation, outcome, or condition relative to a specific claim or expectation. It signifies a negative result that occurs when the expected outcome is less favorable than anticipated.
Plain-English Translation
Imagine something bad happens in a lawsuit or contract—it means the result is worse than what was hoped for. If you expect a win, but the actual result is a loss, then 'adverse' describes that negative outcome.
