Temporary injunctions, often called orders of protection, in divorce cases are particularly troublesome at times. All a spouse has to do is file for one either when the divorce is filed or sometime before it is final and it will be granted. A hearing will be set to extend that injunction for a period of time.
Most of the time there is no process with that system. However, there are times when a vengeful spouse will file for one and the person on the receiving end of the temporary order of protection won't take it seriously and will miss the hearing. The order of protection, whether justified or not, can then be put in place for a certain amount of time. If someone has an extended order of protection filed against them for no good reason, then that will be a black mark against them down the road when they seek employment, get into legal trouble, etc.
The moral of the story is that someone served with a temporary order of protection should contest it at a hearing to extend it whether they take it seriously or not.
