Pragmalji became the heir apparent with the title of Yuvraj Sahib on the succession of his father after passing of his grandfather Vijayarajaji on 26 February 1948.

He was installed in the Tila-medi at Prag Mahal Palace, Bhuj on 17 October 1991 upon demise of his father Maharao Shri Madansinji, under the name and style of H.H.

The royal family was in the court for rights of ownership that was in dispute which cropped up within various sons of Maharaja Madansinhji, who died in 1991.

However, the court had upheld the will of Madansinhji as valid and Pragmulji III as such was declared the lawful owner of these properties, some of which have been converted into luxury hotels by him.

[3][4] Pragmulji III lived in Mumbai and also had a house in London but often came to Bhuj, Kutch to look after his heritage[4] and recently spent time and money in repair and restoration of Prag Mahal & Aina Mahal, which were badly damaged in 2001 Gujarat earthquake.
