The Seoul Central District Court is in the final stages of reviewing a possible extension of Park Geun-hye's detention as the six-month period expires next Monday.
The first ever democratically elected South Korean president to be impeached has been linked to one of the biggest corruption scandals in the nation's history.
The disgraced leader is accused of colluding with her friend to solicit some 70-million dollars in bribes from the country's large business groups.
Other charges include abuse of power, coercion and leaking government secrets.
Prosecutors filed for a new arrest warrant late last month, arguing that Park is highly likely to destroy evidence by coordinating her statements with other key figures involved with the case.
She could possibly be released from custody and appear at her court hearings though.
A decision is widely expected this week.
