Property Distribution in Future

Sir, my father has constructed house by taking home loan on my name and the land is on my father name. I have 3 younger brothers, mother and father presently. I'm only paying EMIs for last 6 years (out of 20 years tenure). At the time of loan sanctioned my brothers were unemployed, so my father was taken loan on my name. Now all they are employed in private sector (salary by hand). Now they are unwilling to take part in home loan repayments. Now My father is also saying to repay the loan EMIs yourself because it's on your name. When i have asked about distribution of property in future, my father saying equal share to all members. So here I need some clarification. 1). How the property will be distributed in future with justification to my repayments? 2). If i clear the loan completely by myself, Can i demand complete property? 3). If not in the case-2, how can i involve my 3 brothers into loan repayment process(they are getting salary by hand not with the bank credit)? 4). If my 3 brothers involved in repayment process now on wards, can i expect more share on property in future(because I've only paid EMIs for last 7 years)? 5). Is there any provision for addition of names in home loan aggrement in banks (persons with non bank credited jobs) Suggest me what should i have to do.
