Division of land

Land property in Bihar ,some in the name of Grand Father and some in the name of Grand mother.Grand father has four sons and one daughter.One son and one daughter not alive the have their children behind. All those property were bought by Elder Son either in the name of his father or Mother (both died),2nd brother though in service but not contributed brother and his family solely enjoyed the grains for his family till father mother alive.None of the brothers family was with him.4th brother was studying on the finance of elder brother.Land was bought by elder brother out of his service income when in service and from coal business during the period of suspension from service. 3rd brother what ever earned from service and what ever got after retirement used to construct self acquired home without sparing any thing to family.2nd brother kept his service amount in fixed deposit.Non of the brother bothered to see elder brother (95Yrs)bed ridden. My humble request is that kindly advise what recourse is left with elder brother? Thanking you. Yours sincerely Ashok Kr Singh Elder son of elder brother
