He immediately entered into service with the British Indian Army as an officer, serving during the Second World War and being promoted to Major by 1948.

The following year, on 25 March 1948, Sir Bhim Singhji merged Kotah into the Rajasthan Union of states and became its first Rajpramukh, but was demoted to Uprajpramukh (Deputy Rajpramukh) when the Maharana of Udaipur, who was of a higher rank than Sir Bhim Singhji, acceded to the Rajasthan Union.

In 1956, Sir Bhim Singhji served as an Alternate Delegate to the United Nations General Assembly that year.

The couple had one son and two daughters: As part of the mass derecognisation of Indian rulers in 1971 under the Indira Gandhi regime, Sir Bhim Singhji was stripped of ruling powers and titles.
