testify as an expert witness
Expert Testimony
In the event of pending litigation against or by your institution, it may be necessary to hire a person who by virtue of education, profession, or experience is believed to have special knowledge of his or her subject beyond that of the average person and which is sufficient that others may officially (and legally) rely upon his or her opinion as an expert witness to provide both oral and/or written testimony to assist the trier of fact to understand the evidence or to determine a fact at issue.
