It can be very difficult to prove that the health care team was at fault for your child's injury. To determine fault, you will need to prove that the doctor or medical staff were fully responsible for the birth injury and that it happened because of their negligence. Your lawyer will gather evidence to show the medical team's negligence directly caused your injury. They will use several forms of evidence, including an exact timeline of how the injury happened and when it took place. The attorney will also gather medical records and opinions of expert witnesses to prove that things weren't done appropriately.
