noncorroborated
Without supporting evidence
Noncorroborated describes evidence, testimony, or claims that lack independent support or verification from other sources.
In legal contexts, noncorroborated testimony stands alone without additional witnesses or documentation to confirm its accuracy.
The prosecution's case relied heavily on noncorroborated statements from a single informant.
The term carries an implicit suggestion of weakness or unreliability, since corroboration typically strengthens credibility.
