Legality of Wedding Officiant

My fiancee and I are getting married in July. Neither one of us are particularly religious. A good friend of ours has become ordained through Universal Life Church ( If she performs the ceremony and signs the marriage certificate, will this be a legal marriage? This will take place in Wake county. Thank you for any and all advice. If a referral is in order, please refer to someone who can answer or refer!

Yes, marriages done by the Universal Life Church are valid in NC.
