Patil was married to Vidyatai Patil in an unconventional wedding. Vidyatai had been to some of the talks held by Shivajirao as a freedom fighter and was inspired by his zeal and dedication to the cause. Though betrothed to another man, she sent Shivajirao a note saying she would like to join his fight for freedom. They were both atheists and non-ritualistic and their wedding was solemnised by Sane Guruji. The marriage, conducted in 1938, lasted for 77 years Vidyatai Patil died in March 2015. The marriage remained harmonious and rock-solid through all the travails of a life that included imprisonment for 12 years, the glory of ministerial power and status, the tumultuous personal life and death of a film-star daughter, and the need to raise her new-born orphan son. The Patils were the parents of three daughters, namely Anita, Smita and Manya. Anita was married to Shankar Deshmukh, the couple have two sons,.

Smita became pregnant by this relationship and gave birth to a son in December 1986. She died immediately after giving birth to the child, due to complications arising from childbirth.

Prateik, who only had sporadic and occasional contact with his father Raj Babbar, looked upon Shivajirao Patil and Vidyatai Patil as his parents for all practical purposes. Prateik hence regards his grandmother as "Ma".
