She left her family in western Nepal and travelled some 200 kilometres to her employer's home near the Indian border.
Her harsh new life began at 4 AM, the start of a daily routine in which she would clean her employer's house, wash dishes, cook and then go to his relatives' homes to do the same, before falling asleep just shy of midnight.
"I couldn't cope with the work, so my employer's wife would beat me with pots and pans, and threaten to sell me to another man," Chaudhary, now 22, told AFP.
When she met her father a year later, she begged to return home, but her father, a bonded labourer, said they couldn't afford to raise her or her younger sister, whom they had also sold into domestic slavery.
Nepal's indentured "kamlari" girls- some as young as six- are among the Himayalan nation's most vulnerable citizens, subject to beatings and sexual violence while being kept as virtual prisoners by their employers.
Every January, when Nepal's Tharu community celebrates the Maghi festival, marking the end of winter, destitute Tharu families also sign contracts worth as little as USD 25 a year, leasing their daughters to work in strangers' homes.
A century ago the Tharu, said to be descendants of the Buddha, owned their farms and lived in relative isolation in the malaria-infested Terai plains, enjoying a natural resistance to the disease that the higher castes lacked.
But when malaria was eradicated from the fertile region in 1960, the Tharu were displaced by higher-caste farmers, becoming indebted serfs in their own land.
Many, like Chaudhary's impoverished parents, resorted to selling their daughters into domestic slavery, establishing the kamlari tradition, which, although outlawed in 2006, persists across the country.
At the age of 12, Chaudhary learnt to read and write. Today, the business undergraduate cuts a confident figure, fashionably dressed in a trench coat and conversant in three languages.
