A Protection From Abuse order can be removed in Pennsylvania under certain circumstances.
If you're at the stage in the case where it's the Temporary PFA, the Temporary PFA can be removed by going to court, and addressing the matter at court, the Temporary PFA can be removed by either agreement between the parties, negotiations. In other words, to try to get the plaintiff to withdraw or dismiss the case, and in doing so, the Temporary PFA would be removed, or by going to trial. In going to trial, the defendant would have to win the PFA trial for a PFA order, the temporary order that is, to also be dismissed which in essence would be removed against the person.
If it's a Final PFA order, it's a different consideration. In essence, you would have to get the agreement of the plaintiff to consider going back to court to ask that the PFA be removed, the Final Order that is. Having an experienced Pennsylvania PFA attorney can help you best understand and navigate the process, and they should be involved from as early as possible in the case.
