Can son claim grandfather's shop as promised by father for the same

I got married in January 2012,My wife was selected by my mother and I was in other city working in a company,I trusted my family so I don't even came to see her,after a few months my mother started to put pressure on my wife for dowry and in front of me she would show like my wife was telling the lie as I was out on work whole day,One day my father, mother and brother beat my wife,as a result she filed a complaint against them.As a result my mother and father insisted me to go out with my family on a rented house and promised me that they will give me the rent of the house and give me my share in a year but now they are refusing from to do so, please advise me as I am not able to support my family as I had a accident in which my left hand was damaged and I have lost the job.I had worked in my grandfather's workshop for 10 years with my father against his promise that this workshop would be given to me as I was not paid any wages. Now my family is not giving me that also
