Disputed property or not?

Transfer of mother's property in the name of Neelu, one of four daughters, is invalid, if property is an inherited by mother. In such circumstances, consent of all sisters for sale of their share in favour of Neelu is mandatory.

Whether mother has granted attorney to Neelu, one of the four daughters, who has executed sale deed ?

Person has to be sound mind for appointing an attorney or executing a sale deed. Hence your mother as well as Neelu (on behalf of mother) is incompetent to sell her property.

Mother has not granted attorney to neelu, it is the transfer of registry that happens in blood relation (exempted to any stam paper), neelu was the right full owner of that property as intkal was updated to neelu's name too. Neelu has sold that property to my uncles, she had executed the sale deed now that property has been registered on my uncles name but we are waiting for the intkal to be updated to my uncles name too.. Plz help

If the original owner was mentally unfit at the time this property was transferred to one of her daughters name, then that transfer is illegal and invalid.

But the person who objects this has to produce the documentary evidences to prove that the owner was mentally unfit. 

if proved then the subsequent sale by the seller would also be vitiated. 

The claimant can file a suit for partition to claim her share in the property as a right provided the original owner is not alive 

It can haras us by any mean or we will not be a part it?

As the seller is at fault but how the buyer will know that why the property is transferred to the daughter

And if once intkal is updated to my uncles name still we will be a part of it? Plz reply

Any further and proper opinion can be rendered only after perusing the relevant papers or documents.

You may better discuss with a local lawyer and take decision accordingly.

IF the property was owned by Lady and the transfer was done through legal process then her daughater can sold the property but if the lady will be proven as mentally unfit to act for herself then the resgistry can be challenged by her daughters
