Jennifer has been approached by an attorney who is representing one of Jennifer's attest clients in litigation. The attorney needs a person who is knowledgeable about the client and who also understands forensic accounting. Jennifer seems to have the necessary qualifications because she has supervised the client's audits for the last four years and, through a combination of forensic accounting experience and having passed an examination, has earned the CFF credential. During Jennifer's initial meeting with the attorney, she asks the attorney whether he is engaging her to testify as an expert witness or as a fact witness. Why would Jennifer ask this question?
