Ordinarily, in Arizona a medical malpractice case takes between one to three years to resolve. The length of time varies to a certain degree based upon the number of parties involved, the number of depositions and the amount of investigation required, court scheduling and calendaring, the calendaring of expert witness appearances and many other factors. In almost all medical malpractice cases, attempted resolution of the case through mediation is required. Mediation, however, is not usually scheduled until most of the discovery has been completed and depositions taken.
