Intestate property case

The scenario : My parents have bought a property in kolkata ( Dum Dum Cant) measuring more or less 22 kattas ( 15,840 sq,ft) on 1956 and during my parents life time 20 kattas of land has already been sold out time to time due to the marriage, education medical and other expenses for day to day livelihood of our family since my father was a employee of a private firm with a very low salary. I am the only son of my parents along with other six daughters, all are married and settled on their own. Out of six one sister has expired 10 years before from now leaving one son. The entire property is in my mothers name who has suddenly met an accident and finally expired due to assumed medical negligencies of one of my married sister conspiracy which I’m sure 01.05.2003 since I have been working in new delhi. Shockingly they buried my mother’s dead body very quickly after releasing from the hospital before me reaching at the spot so they totally deprived me from the “mukho agni” last ritual, and I was unable to see the last of my expired mother. Now we have one residential house on more or less 2 katta land having 2 and 1/2 rooms aged almost 55 yrs, where now I am leaving since after her death with my family. Since the said house on 2 katta land is unsettled so some of my sisters is forcing to sell my residential house and claiming their equal share. If I sell the said house then I will have to be a land less/homeless to live with my family. Secondly some of my sisters is forcing me and threathning me with very insulting slang language to submit the accounts before them of the said sold out property which have already been sold with the present and onsent of my mother long back. With all those I feel very helpless and feel mental agony and torture. Now I want to know “ Mukho Agni “ is my legal right and if it is then how I can get justice for such cruel activities made by my sisters, Does any married daugher have any legal right to bury the dead body on their wish inspite of the presence of son of the deceased old lady. Any married daughter has any legal right to raise any question all about the money for sold out land which the owner sold out during her life time, Please advise what is to be done by me so that I may get rid of that mental agony. What I want if possible : The house that is mentioned is very old and very dangerous, so I want to transfer the house to my name and want to proceed the mendings and renting by taking loan. But how to do so if the sisters are not allowing and harrassing me from transferring the name . The house’s condition is very dangerous so I need to do something fast. Could you please guide me the possible ways, so this problem could be solved .
