Dhananjay and Jagriti were arrested on November 5, last year in connection with the death of their 35-year-old maid Rakhi Bhadra, a resident of West Bengal.
While Dhananjay is out on interim bail, Jagriti is lodged in Tihar Jail under judicial custody.
Additional Sessions Judge (ASJ) Lokesh Kumar Sharma had earlier dismissed Jagriti's plea for interim bail on health grounds.
She had sought bail submitting that she needed to undergo surgery for her ailment and that she has only one kidney.
