Can a gift deed revoked - Reg.

Can a gift deed revoked even after 15 years of execution. My parents have four children (two sons and two daughters), I am 2nd son and last child to my parents. My father has gifted me his self acquired house duly executing a gift deed in the year 2003 in my favour (2nd son), to express his gratitude towards my act of leaving my good Bank Job in the year 1992 and looking after my parents (then I was unmarried) as his wish. on his request to stay with him in the same house (which was gifted to me in the year 2003) since I lost my future prospects fiscally, socially, mentally by leaving the bank job. Also it is mentioned in the gift deed that “I will stay with my parents to look after them). I got married in the year 1995 and stayed with my parents in the same house for 10 years i.e. till 2005 along with my wife duly attending my parents with great love and affection. But all of a sudden due to the influence of my sisters and brothers-in-law my parents started disliking me as well as my wife & my 6 year old son (my sisters and brothers-in-law became very jealous about my importance in the house). My elder brother (1st child of my parents) is always away from my parents since he got married i.e. in the year 1985, he only enjoys the rights and property but does not take any responsibilities of the family. Due to my sisters and brothers-in-law influence my parents themselves asked me to vacate the house. Now, I am staying in a rented house. My elder brother and sisters are very often coming to my parents house to take some money from them and influencing my parents to distribute the property equally to all the 4 children including the house which was gifted to me. In this connection, Please let me know : A) Whether the gift deed can be revoked even after 15 years of execution on the grounds “ that I am not staying with my parents and not looking after them” as the condition is mentioned in the gift deed B) Whether the daughters who got married in the years 1983 and 1985 have the right to have share in the parents self acquired property. Please advice me what to do if the gift deed is revoked by my father. Thanking you sir.
