You can represent yourself in court but will be expected to follow procedure just as a lawyer would. You will not receive a break from the court for your inexperience so self representation in a contested divorce is extremely risky and not recommended.
If your divorce is uncontested, hiring a lawyer is not always essential. The self-serve center has forms that individuals can fill out and apply for a divorce. However, you should see a lawyer prior to filing for divorce to make sure there are no other viable claims that you wish to pursue.
In North Carolina, if you are granted a divorce (i.e. the judge signs the divorce papers) then your claims for alimony and equitable distribution are barred. You need to consult with a lawyer to make sure that you understand your rights on the issues of alimony and equitable distribution prior to filing for divorce.
