One of my eldest sister marriage happened before 1985 and other 2's after 1985. Can my eldest sister ask for share of land or demand money from us(three of us) ?

Since this was your father's property and he made testamentary disposition of his property in favor of your mother, she became the absolute owner of the property with marketable title in her favor. Therefore the transfer of the property in her name in favor of you and your other two brothers by executing a registered gift deed is very much valid and irrevocable. Hence your elder sister or any other sisters or any third person has any right in the property which stands transferred on you three names.

Can the rest 2 of my sisters file case on us to get the share or demand money from us? If yes, then how much share will they get or what percentage of money they can claim ?

These two sisters also do not have any legal rights in the property

Since it is a gifted deed from my mother, do they have share on the property ?

Your sisters do not have any right or share in the property.

Can they two claim money or file case on me alone but not on my two brothers? It is, am afraid, conspiracy 2 of my brothers and 3 sisters planning against me. If they can, how do defend myself from them?

There is nothing to be worried about it.

Since you possess registered gift deed in your possession and subsequent partition deed also in your favor, they cannot claim any share or money from you.

Let them enter into any conspiracy, legally they cannot snatch the properties or money from you.

What we are afraid is he might file a case against us(asking for his wife's share) after he has money in hand. We don't want any share of land from him unless he plans to file against us.

He does not have any right to file a partition suit against you on behalf of his wife.The court will reject his suit, vis a vis you also cannot file a suit on behalf of your wife.

My question here is, Once he sells the land and targets us, can we file against him claiming for my wife's share, would this be of any worth then? since the land is already gone. Or should we file the case now it self to be on safe side?

Only your wife should decide about it.

Can we have middle ground deal(me, my wife and my 2nd sister and her husband(my wife's brother)), like we wont claim money from each other ?

Dont go for any such agreement it is an unnecessary problem which may develop into complication at a later stage.

1) once gift deed is executed by mother you would be absolute owner of property

2)sisters would not have any share in the gifted property

3)even if they file case they may not succeed

4) your wife can file case against her brother claiming share in land standing in name of her deceased father and fraudulently transferred in his name

1. In accordance with gift deed the title transferred instantaneously to the donees i.e you and your brothers, so your sisters cannot succe

ed to the property unless they successfully challenge the gift deed in the court on the grounds of duress or undue influence. No share devolves to your brother-in-law.

2. You and other donees are free to alienate your respective shares.

Sisters can file suit to challenge gift deed but they have to prove allegations made that gift deed was executed by undue influence

2) chances of success for setting aside gift deed are bleak

3) if they win they would have equal share in property

The burden to prove that they were forced to sign will rest on them and even though they may make an attempt, it should be seen whether such a claim is barred limitation.

Also it is not a joke that the registered gift deed can be revoked on some flimsy reasons or at their whims and fantasies.

They have hardly any chance to prove their case or win it.
