Ancestral house shares transfer

Hi all Greetings. My query is as below: My grandfather left a house to: 5 brothers and 2 daughters including my father. The property is not yet transferred into all legal heirs due to family issues and some heirs being abroad. Now, eldest son and second son are no more and suceeded by thier wifes and kids their shares are now equal shares for wife and kids. At this stage now we are looking to get property transfered to legal heirs. -Will the property mandatory transfer first to all legal heirs including wifes of deceased and kids? - is there a way or doucment they can provide that property is directly transfered to someone legal heir at registration? - more importantly, if 3-4 legal heirs can provide any document to my father's name that thier share can be considered gifted to him even before partition or transfer? What document they cam provide being overseas In other words, if 2 of the existing heirs do not cooperate, can the rest of owner ship percentage still either be transferred to my father with required permissions from balance of heirs ? Can anything in that be considered legal and valid? Is there any way to do this with out 2 heirs agreeing, keeping note we will not be transferring or touching their share in property Thanks in advance for your valuable Thanks Appreciate your time
