Time-bound courthouse logistics
Courthouses have strict schedules. Your ceremony slot may be at 10:15am and the next couple is at 10:45am. Know this going in, arrive 20 minutes early to scout the room and the post-ceremony portrait area, and have your camera settings locked before the judge begins. Bring a wide-angle option — courthouse ceremony rooms are often small with unflattering overhead lighting. If there is a window anywhere in the room, position yourself to use it.
