Expert witnesses are not uncommon in child custody cases, and it is not uncommon for both parties to hire multiple expert witnesses when a child has extensive needs. Getting what you want in a family law case oftentimes rests on expert testimony and other evidence you present in court. In a previous article titled, Psychological Testing and Health Evaluations in Illinois Child Custody Cases, we explained that either party or the court can request that a mental health evaluation be conducted by an expert in the mental health field. At times these mental health experts who perform these evaluations may also be called upon by the court to testify their findings and recommendations.
