Kharak Singh was brought up in his family's martial tradition and assigned to a variety of military expeditions. While barely six years old, he was given the command of an expedition to conquer
Sheikhupura the prince's mother then was gifted
Sheikhupura Fort by his father. In 1811, at the age of ten, the precocious Kharak Singh reportedly asked his father for control over the estates of the
Nakai Misl—his mother’s kingdom—promising that he would render a far greater tribute than his cousin,
Kahan Singh Nakai. His request was granted. Despite the revered
Baba Sahib Singh Bedi's support for the Nakais the Nakai estates were obvertaken by Kharak Singh claiming he is "the grandson of the Nakais" while Kahan Singh Nakai was allowed to retain
Baherwal with a jagir worth Rs. 20,000. At a young age, he was engaged to Chand Kaur, the daughter of Jaimal Singh Kanhaiya of the
Kanhaiya Misl, a match arranged by his father to ensure that the Kanhaiyas could not directly oppose the Sukerchakia heir-apparent. Following his marriage in 1812, he was placed in charge of the
Kanhaiya estates. That same year, he was deputed—along with
Dewan Mokham Chand and his tutor, Ram Singh—to punish the recalcitrant chiefs of
Bhimber and
Rajouri. Later in 1812, Kharak Singh received the principality of
Jammu as his
jagir.
Maharani Datar Kaur had a deep influence on her son and paid great attention to her son's education, as a result Kharak Singh mastered several languages and developed interests in cosmic sciences from an early age. Like his parents, Kharak Singh was deeply religious since childhood. He was a devout Sikh and admired for his piety and simplicity. Kharak Singh shared a close relationship with his parents, particularly with his mother. He cared for her deeply and was devoted to her throughout his life. Upon her death at Sheikhupura on June 20, 1838, he is recorded by Suri as having been inconsolable. He mourned for twenty-one days, attended no public meetings, and was unable to eat properly. Ranjit Singh even remarked to his son that he had lost a great deal of weight. His consort,
Yuvrani Chand Kaur, personally supervised the distribution of alms in commemoration of her mother-in-law. == Administration as the crown prince ==
