What do I write a judge for my divorce case if I can't make the calendar call?

Draft and send multiple copies of a basic letter to the court clerk's office (one to file with the court, one to be delivered to the judge, one to be stamped & returned to you as proof you filed it), in addition to sending a copy to the opposing attorney or opposing party (if they are unrepresented). Depending on what your possible conflict is (e.g., a doctor's appointment, a previously planned trip, another court matter, or something else that you believe would be considered sufficient to justify granting you a leave from the calendar call), you may be able to be exempt from attending the calendar call, but keep in mind that being exempt doesn't exempt you from still properly notifying the court (especially the judge) of the status of the case, what you plan to do (e.g., trial, settlement, dismissal, etc.), and it doesn't exempt you from whatever court schedules are in place. Good luck.

I agree with the above answer, and would add something that cannot be overemphasized: you are not excused from court until the judge has excused you; asking is not getting. You can ask for a continuance but you don't get a continuance until it's granted. Don't skip a hearing after asking for a continuance if your asking wasn't followed by some getting.

Many courts now have a system where they allow you to appear by telephone. Call the clerk immediately to set up this telephone appearance. You can always have an attorney hired for the day to request a continuance until you are able to make the court hearing.
