Out of State divorce questions

My wife and I separated last April. We filled out, signed, and had notarized a separation agreement which she claims to have turned into the court system. It is time that I think we should move towards finalizing the divorce, but I am currently living in SC. In order for the divorce to proceed in Cleveland County, where she lives and I still work, will she need to be the one to file? If not, can you tell me more about the process?

So long as she still lives in NC, you may file.
