Trials are usually held at the Guma' Hustisia on Saipan, but the court also conducts proceedings at the Kotten Tinian and the Centron Hustisia.

Kotten Tinian opened in 1999, allowing residents to file cases on their home island rather than traveling to Saipan to do so. It is conveniently located in San Jose. It received further technological improvements in 2017 and 2018. Recently, CARES Act provided funds for fiber optic upgrades at Kotten Tinian.

Superior Court hearings are held on Tinian twice a month, and the Supreme Court periodically holds oral arguments. 

Rota Centron Hustisia in Sinapalo was completed in 2005. It houses the Superior Court, Office of Adult Probation Supervision, Office of the Attorney General, Office of the Public Defender, and Department of Public Safety.

Superior Court hearings are held on Rota twice a month, and the Supreme Court periodically holds oral arguments.
