For claims involving a malignant condition, the trial court will be required to hold a hearing to determine if the exposed person’s cancer is asbestos-related. Within 45 days of filing an asbestos or silica action, a plaintiff must file a sworn information form that specifies the evidence that provides the basis for each claim against each defendant and include supporting documentation.

The law applies to all asbestos claims filed on or after August 1, 2021.
