If there's a way to make things hard, there's always someone out there willing to do it, isn't there! I'm so sorry you're going through this.

I can't offer you legal advice. I've never practiced in NC and I am retired in the jurisdiction in which I did practice.

That said I did google NC, Greensboro (which I once visited and sorry, HATED, but that's another story for another day), and found this link from the court that may help. There's a guide apparently to help you fill out the forms. I don't know if you're up to looking at it right now or how much help it is, but here it is:
