The Bt772 million plot was at the centre of graft litigation in 2007 which led to Thaksin's conviction for conflict of interest and his two-year jail term.
The Supreme Court found Thaksin guilty of conflict of interest by using his position as prime minister to influence the transaction between Pojaman and the Financial Institutions Development Fund (FIDF).
Citing the high court's verdict against Thaksin, the FIDF subsequently sued Pojaman to return the plot.
Pending the completion of the civil litigation, Pojaman is banned from putting the plot on the market.
