testimony legal definition

Statements made by competent witnesses, who have been sworn in at a trial or deposition or in an affidavit. Although frequently used synonymously with evidence, the latter is the broader term and encompasses both testimony and physical evidence.

Testimony given by an individual with special qualifications or credentials that enable him to provide information to the fact-finder to assist with resolving the ultimate facts in issue.  Also known as “opinion testimony,” because, as opposed to “fact witnesses,” expert witnesses are permitted to give their opinions.
