Register at the JPORTAL website and complete your juror questionnaire. You can sign up for text or email notifications or request an excusal or deferral.The form will be available at each jury reporting location. I just got a jury summons and it says I have to call in for a full week to see if I'm needed. Last time I was summoned, about a year ago, it was for a day. You will be required to make only one appearance in court for jury selections held that day, or serve for one trial (jury selection may take more than one day). The information on this page is about juries in Michigan's state courts. However, you may also be called to serve on a federal jury. I was called for Federal Jury for San Diego, CA a couple of years ago. There is paper work you have to fill out ahead of time before you report.
