Division of property which is in the name of my mother and still not

We are 2 brothers and 2 sisters. Our house was in the name of my mother who passed away 3 years back.my father passed away 2 and half years back.my sisters are married. One of them is divorced and lives with us .my brother is married and I am single. House is still in the name of my mother. Due to strained relationships I would like to move away get married and settle down. The house is small and we are 8 persons living together. My siblings don't want me to marry and bring my wife to this house. I cannot afford to rent a house because my income is low. How can I sell the house and with my share settle down. I am 48 years of age. Time is running out for me. Please help and advice me how to go about it through law. Thank you
