If your case looks to be a meritorious one, experts in the appropriate medical field of specialty must be consulted and ultimately retained in the case. A medical malpractice case cannot be won without a medical expert. A good expert who is willing to testify can be hard to find, but it is an essential aspect of proving a medical malpractice case. Often times, because local doctors can be reluctant to testify against doctors in their own state, with whom they may have a pro-fessional relationship, experts may be contacted that are located out of state. Most experienced medical malpractice lawyers will know how to locate and contact the right expert for your case. The expert will review the medical records and determine whether, in his medical opinion, a standard of care was violated.
