Justice courts have some flexibility in how they handle motions. A court can set up regular days and times when people come in to argue their motions out loud in front of the judge. This gives everyone a predictable schedule for these types of hearings.
The court can also decide to skip the in-person hearing altogether. Instead, the judge can make a decision just by reading the written arguments both sides submit, called briefs. This means your case could be decided without you or your lawyer ever stepping into the courtroom to speak on that particular motion.
What this means for you is that you need to pay attention to how your local justice court operates. Check whether they require oral hearings or if they typically decide motions based on paperwork alone. If you don't know which approach applies, ask the court clerk or check local rules so you don't miss a chance to argue your side in person if that option exists.
