Is an expert's testimony admissible in a civil case?

Moreover, expert testimony is admissible if is " '[r]elated to a subject that is sufficiently beyond common experience [and] would assist the trier of fact." (People v. Torres (1995) 33 Cal.App.4th 37, 45.) As noted by the trial court, as in a gang case where an expert can testify as to the particular meaning of gang signs and paraphernalia, the language in the Fabricated Documents was unusual. The expert testimony was relevant to advise the jurors this was not a normal transfer of Property, and showed the Fabricated Documents were false.
