Her mother, actress Sharmila Tagore, wants her children to settle down soon in their lives, but Soha has a different view on marriage.
"We have taken a big step together where we are living together, which is equivalent to being married. For me, that's the biggest step," Soha told IANS.
"She is a mother and she wants her child to be settled. But for me, moving together was the biggest step. Now whether we get married or when we get married is not on my mind right now," the 34-year-old, seen in films like "Rang De Basanti", said.
"For me, this is the biggest commitment and we have made this commitment to make things work. The formality is just associated with signing paper, but the value and commitment is more important to me," she added.
In fact, Soha's actor brother Saif too tied the knot with actress Kareena Kapoor after they had been staying together for five years.
Soha has just wrapped up shooting for "War Chhod Na Yaar" in Bikaner.
