Suu Kyi, who has been detained since the coup, held a face-to-face meeting with her legal team for about 30 minutes before the hearing in the capital, Naypyidaw, her lawyer Khin Maung Zaw said.
"We discussed the cases (and) what line of defense we should take," Khin Maung Zaw said. "She wished the people good health and prosperity."
Prior to the hearing, Suu Kyi had only been permitted to speak with lawyers via a video link in the presence of security personnel.
The ousted civilian leader, whose National League for Democracy (NLD) party won a landslide in November 2020 elections, has not been seen in public since her detention.
According to Khin Maung Zaw, Suu Kyi had complained that 30 minutes was not sufficient to discuss all the cases against her, and urged her legal team to ask the judge to permit another meeting.
The lawyers also met with ousted President Win Myint, who was detained on February 1 alongside Suu Kyi, and is facing charges.
According to Khin Maung Zaw, Suu Kyi said of the NLD: "Our party grew out of the people so it will exist as long as people support it."
