Step Sibling marriage

Hi, I realize this doesn’t have anything to do with divorce or separation or custody but I really need an answer. Realizing to that there is no blood relation I have looked for the answer and the law and nothing is clear. I have seen where the definition of brother/sister in North Carolina includes step siblings though. My question is…Is it legal in North Carolina to have a relationship with and potentially marry your step sister?

In North Carolina, the laws prohibiting marriage only address blood relations. There is no restriction related to step-siblings.
