The court has also imposed a penalty of Rs 20,000 each on Vikram Gond, father-in-law Subhnarain and mother-in-law Prema Devi, who had immolated the victim Arti in May 2013 over dowry.
The victim's family had lodged an FIR against Arti's husband and in-laws, the prosecution said.
After hearing both the sides district judge Chandrahas Ram held the trio guilty yesterday.
