CAOC has an excellent resource page for Court-related coronavirus updates
If you are having trouble keeping track of the Wuhan coronavirus closures, you are not alone. 58 counties in California all have their own court closure plans in place. CAOC has assembled a one-stop-shop for following these frequently changing closures here. I believe you do not need to be a CAOC member to view this page. This tool is a stress-reliever when you are trying to figure out what you can file, where, and how.
