Diwan Singh was a follower of Sardar Charat Singh Sukerchakia and fought under him against the Chathas.

He built the village of Qila Diwan Singh in the Gujranwala district, and his holding consisted of the villages of Badangil, Chak Chata, and Kotgarh, worth about Rs. 3,000. He was killed in a fight with Nur Mahomed Chatha at Akalgarh.

His only son, Hukam Singh, entered the force of Sardar Mahan Singh and, on his death, that of Maharaja Ranjit Singh, and served in the Kasur, Kangra, Jhang, Multan, and Yusufzai campaigns.

He was killed on the banks of the Lunda River in an affair with the Yusufzais.

On the death of Hukam Singh, the villages of Qila Diwan Singh and Kotgarh were confirmed to his son Soba Singh, who had served under Misr Diwan Chand and Bhawani Sahai in Kashmir.

He was engaged in many battles on the North-West Frontier — Khakha, Bamba, Saidu, Teri, and Peshawar.

In 1848 he remained loyal and, with Sardar Bur Singh Mukerian, furnished the British army with supplies.

After annexation, his two villages were maintained to him on payment of one-quarter revenue.

His eldest son, Ratan Singh, held Kotjodh, worth Rs. 100. Sarup Singh, his second son, was killed in the Battle of Battle of Sobraon.
