You should file an emergent application, otherwise known as an order to show cause, for a custody and parenting time schedule, alleging that the urgency of the matter is your child’s illness and your wife’s refusal to let you see the children for however long is doing immediate and irreparable harm. That is the standard that the Court’s look to when granting orders to show cause, so it is very important that you allege in your papers and explain to the judge, if and when given the opportunity, that the children are at risk of immediate and irreparable harm by your wife’s refusal to let you see them. This must be done in the county in which your wife filed for divorce, and under the same docket number. The Court may not take the case on an emergent basis, but, if it does not, then it will likely convert the application to a regular motion. If for whatever reason the Court denies the emergent application, then you must immediately file for the same relief by way of notice of motion. Either way, the staff at the Courthouse will be able to give you the appropriate forms, or you can access them on the New Jersey Judiciary’s website under Represent Yourself in Court. Generally, orders to show cause by self-represented individuals must be hand-delivered to the Court (you can go to the Court and fill it in while you are there) and the judge will hear your case that same day.
