Sangwian Raksaphet, the rice grower from Lop Buri's Khok Samrong district who set herself on fire at the Government House public service centre last October, passed away on Monday night.
The woman, 52, battled severe burns for five months at Bangkok's Vajira Hospital and ended up dying from a blood infection.
Sangwian had sought help to pay a Bt1.5 million (S$63,285) debt to a moneylender. After seeing no progress from a complaint filed in August, she arrived at the centre at about 8.45am and poured petrol all over herself before lighting herself with a lighter.
Relatives and neighbours yesterday made preparations for her funeral at Wat Rachawantanaram (Thalung Leknoi) in Khok Samrong.
Lop Buri governor Thanakom Jongjira was scheduled to preside over her bathing ceremony in the evening, while the relatives will set a cremation date later.
Rian Aramthong, 78, said that Sangwian was a good daughter and now she would have nobody left to care for her.
