Mysterious deaths and missing criminal case

when did your grand father died ? is it after 1956 ? if yes then all the sisters along with the brothers have got equal share in the property of your grandfather. Since your uncle F vanished fromthe house then pls let us know how many years he has vanished ? if he has vanshed 7 yrs or more than thant time period then he is considered to be dead inthe eyes of law. so his share of property vests upon rest of the sisters (as considered F  to be unmarried ) . Now the co sharers of th property is all the sisters irrespective of divorcee, widow or whtatever. All the sisters will get an equal share of their fathers property as their father has died intestate. (i.e. died without making any will) . Your mother can file a partition suit to get the equal share of the property. By filing this suit you have to file an injunction pertition U/o- 39 R-2 of CPC. this petition will help you to prevent your other Aunts to demolish the property as there would be an status quo order for filing this petition.

As far as the mysterious death is concerned you will have to file a misssing complaint inthe local ps and police will do the rest.

Grand Father died after 1956...son F is vanished more than 7 years but they never filed missing case with the police..my doubt is they would may killed and buried him in the house so they didnt complaint missing case in the police station, if i complaint in the police station is it enough for that or do i need to mention my doubt with the aunt D and E in the complaint at police station.

instead of my mother being an elder son can i file a case on them behalf of my mother or as a coparcenary since the propery belongs to the grand father.

I have one more concern here..property like two houses and agricultural lands are visible to every one but there was some money in the post office that they have drawn and gold and silver they took for that there is no proof..is it possible for the court to give rights to search in their house for the gold and silver by giving orders to a concerned person.

Let your mother file the partition suit. You or ur mother have to file a missing diary about ur Uncle. you can express ur doubt to police about ur other two aunts but remember one thing..... this will lead to a criminal case. and civil case once initiated before criminal case will not be disposed before the disposal of criminal case. It will stalled for years after years. Before all this u pls deciede what you want : to know who killed ur long lost Uncle or you want to get the share of the property. If u want to get the share of the property then only file a missing diary. if there is any skeleton in the cuppboard then it will automatically come out . you dont have to do anything.

Moreover , as far as the property is concerned make a list of all the properties of ur grandfather including fixed assets , gold liquid asstes etc. and include everything inthe schedule of the property inthe mentioend itbneh partion suit. Just obtain a status quo on everyhting so that they cannot operate any account or sell any gold or silver ornaments. Just cosult a local lawyer he / she will help u out. Let the partition case be filed by ur mother , after that u obtain a special power of attorney for court appearences on behalf of ur mother.
