A North Carolina-headquartered credit union is trying to stop the recently merged BB&T and SunTrust from changing their name to Truist. The banks completed their $66 billion merger in December. At that time, they said that the transition to the Truist branding would occur over the next two years. However, Truliant Credit Union, which has locations in North Carolina, South Carolina and Virginia has filed a motion for a preliminary injunction against the merged banks in US District Court. Truliant has also filed an infringement lawsuit against the banks. The injunction asks the court to prevent BB&T and SunTrust from using the "Truist" brand name for the duration of the lawsuit.
