Alleged fraudster Monta "Ying Kai" Yokrattanakan entered a not guilty plea in the Criminal Court on Thursday to a lese majeste charge.
The court set Nov 21 for a preliminary hearing to examine evidence and witness lists after the 56-year-old affirmed her innocence and said she would defend herself in court.
Ms Monta was arraigned on Wednesday for insulting the royal institution in allegedly telling other people she was a khunying, a title bestowed by His Majesty the King, and was close to the royal institution. The false claim was used to seek undue favours and benefits. The offence was committed between May 2012 and August 2013 in Bangkok's Chatuchak district, the prosecution alleged.
Ms Monta appeared calm and was wearing a surgical face mask when she was taken from the Central Women's Correctional Institution to the court on Thursday morning. She has been detained at the institution since July 7 after the court rejected her bail request.
The woman has also been charged with lodging false complaints, human trafficking and defamation, all of them currently still under police investigation.
Ms Monta woman made headlines earlier this year after her former housekeepers accused her of lodging false complaints of theft against them. The complaints were said to have been filed in retaliation for the women's refusal to accept Ms Monta's offers of "highly-paid employment", said to be related to prostitution.
