Yes, but your attorney will, in most cases, locate an appropriate physician/expert witness. Virtually every medical malpractice case requires expert testimony from a physician who practices in the same or similar field as the defendant, and in some cases you will need expert physicians from a number of different disciplines to prove your case. If your case is against a nurse, pharmacist or other non-physician, you likely will need an expert witness from those disciplines to testify as to the relevant “standard of care.” Finding a highly qualified expert witness to testify that a doctor was negligent is often one of the most difficult aspects of preparing your case.
