on father demise your mother , 5 sisters have equal share in property 

2) if you sell the property sale deed would be set aside

3) you can only sell your share in property 

Yes they can claim this year in the property asas they have right to have equal share in the ancestral property.

Now this is up to you to go legal I give the share to your sisters without any legal dispute they can file a petition case in the court to get the property distributed.

As long as this isn't a self acquired property of your father, your sisters do not have any share in this property.

Since your father died before 2005, your sisters cannot be given the benefit of Hindu Succession amendment act of 2005. 

You can only sel your share in this property, because there could be other coparceners having interest in this property. 

See the nature of the property has to be seen if it was ancestral property that is 4 generation old and is a hindu joint property and was not further partitioned in any generation then they cannot claim otherwise if the property was partitioned then they can claim as intestate succession of the father. 

If you sale the property and there share is established in court the registry can be cancelled and the seller can proceed against you to recover the amount.

Dear Client,

Daughters have equal share in property and they can claim share in sale consideration or cancellation of sale deed.

What do u mean by Khandani property ? who purchased it.

There is a difference of opinion between 2 Judgement of Supreme court regarding the right to Property after 2005 amendment of Hindu succession Act. One Judgement says that on the date of amendment both father and daughters should be alive. Other Judgement speaks about right of daughter by birth. But the right is subject to liability of family too. If they want to enjoy rights then the liability of family should also be shouldered by them. So as in your case the father was not alive during the date of amendment then they are mostly not entitled to the share but we need to see the view of larger bench of SC

Dear Sir,

If your father did not made registered Will of that property, then the property will devolves among sons and daughters of your father. 

Yes, the daughters can claim.

You cannot sell the property, if you done so the registration may be cancelled.

Your sisters too have the right of inheritance. You selling the property is blatantly illegal... You aren't the sole owner of it

The right of women seeking equal share in ancestral property, the Hon'ble Supreme Court has said that the 2005 amendment in Hindu law will not give property rights to a daughter if the father died before the amendment came into force.

The court held that the amended provisions of the Hindu Succession (Amendment) Act, 2005, could not have retrospective effect despite it being a social legislation. The court said the father would have had to be alive on September 9, 2005, if the daughter were to become a co-sharer with her male siblings.

The property that were on your father's name at the time of his intestate death shall devolve equally on all his legal heirs i.e., his wife and all children.

Hence your siblings are entitled to an equal share in your father's property at par with.

Selling even a portion of property without their consent will be considered as an illegal act and not binding on the other legal heirs.

If they file a suit for cancellation then you will be in serious problem.

if its ancestral property i.e. a HUF property, then your sisters cannot claim

however if its a self acquired property of your father then your sisters are class 1 legal heirs who have a legal share in the property

taking care of your mother is your moral duty. You cannot claim to be exclusively entitled to the property just because you took care of your mother. 

If its a self acquired property and you sell the property without your sisters' consents then they can file a suit against you and your buyer 

Yes, They have equal rights in ancestry property
