Can I file to extend my final civil harassment order beyond 5 years?
Yes, you can apply to extend it and you do not have to show any further harassment since the original order was issued. At any time within the 3 months before the civil harassment order will run out, you can apply for a renewal of up to an additional five years. To file for a renewal, you must file a new petition for a civil harassment order (you basically take the same steps that you took to get the order that is currently in place) and it is up to the judge to decide whether or not to extend it.1
