The court system has many strengths, fast action is not one of them. Court rules require notice, usually weeks in advance to everyone involved in a case. Clients often ask me if I can just ‘call the judge’ to get them what they want. That is almost never allowed.
In rare cases we can get fast action, the legal term is Ex Parte Relief. To do that we need to show the judge that there is an emergency, and that if an order is not granted immediately, without notice to the other side or a hearing, a child, or someone else will be seriously harmed. This is a high standard, much more than just my client will be a better parent, or they do not like what is going on at the other house.
Your best option, try to avoid getting in a situation where you need the Court do it now, and, if you are in that situation, I need solid evidence from you to show the judge that there is an emergency.
