She held a knife against the left side of her mother's neck.
Then she said in Tamil: "I will kill you. I will cut you".
The daughter of a woman who unsuccessfully sued Novena Church for a supposedly botched exorcism was on Monday sentenced to a three-month day reporting order for criminal intimidation.
Subashini Jeyabal, 28, threatened to kill her mother, Madam Amutha Valli, last year.
The day reporting order means that she would have to remain indoors from 11.30pm to 7.30am.
She also has to perform community service for 150 hours.
Subashini, an educational therapist, was also fired from her job at the Dyslexia Association of Singapore after the incident.
She has since moved out of the flat that she was sharing with her mother in Ang Mo Kio, where the dispute broke out on June 29 last year at about 8.30am.
An argument broke out between mother and daughter in the living room of the flat that morning.
During the dispute, Subashini ran into the kitchen and took a knife from the kitchen drawer.
She then went back into the living room, where she threatened to kill her mother, 57.
A family friend, who had been at the flat, then intervened and took the knife away from Subashini, who is a science graduate.
He then took her out of the flat while Madam Amutha called the police.
No one was hurt.
The court heard that Subashini and her mother had "always shared a tenuous relationship" since she was nine.
The psychiatrist noted that Madam Amutha was "constantly provocative" and made "wild, unfounded allegations about Subashini's character".
He said that his patient claimed she was provoked by her mother, who had returned drunk that morning from a nightclub and had woken her up to accuse her of sleeping around for money. These accusations are said to be baseless.
Subashini declined to comment when TNP contacted her.
She was often seen with her mother during the trial in 2006.
Madam Amutha, a private tutor, had sued the Novena Church, two Catholic priests and six churchgoers, after claiming she had post-traumatic stress disorder after they forcibly tried to exorcise her in 2004.
She had claimed that after she fainted at the church, the defendants took her to a room where she was restrained, assaulted and strangled.
She was made a bankrupt in March 2010 after she failed to pay $373,000 in legal costs to the defendants.
