Dear Sir

Your father's property will be divided in two.

You are entitled to 50% share of the property. Your brother is entitled to 50% share of the property.

Since your brother is dead, his share of the property will be shared equally by his wife and son.

Thank you

 If a Hindu male dies intestate, the share in his self acquired property devolves equally to his class i heirs -mother , wife, sons and daughter.

Grand daughter has no right over great grand fathers property . The share of the deceased brother's estate would pass to his wife and son . 

It is your father's self acquired property hence after his intestate death it has been divided between you and your deceased brother's family.

Therefore there is no question of this property to be termed as ancestral property, do not stretch it too far.

The wife and son of your deceased brother are inheriting your brother's share as his legal heirs and not as coparceners  hence there is no question for the granddaughter of your deceased  brother to claim any share in the property for any reason. 

If it's a self acquired property then it's not a matter of right and depends on the owner of that property to share it and no one can receive the same under succession laws if the owner doesn't want to give

- As per law, after the death of your father intestate , his property would be devolved upon all legal heirs i.e. your mother if alive & no sisters , you and siblings equally. 

- Further, after the death of your brother his property can be claimed by his legal heirs only i.e. .his wife and children.

- During the life time of son and daughter , grandson or granddaughter having no right to claim over the property received from your father . 

- It not come under the coparcenary property . 

It is not ancestral property 

grand daughter has no share in the property 

Contact a local lawyer practicing in sub registrar office and get buyer satisfied.  Grand daughter's share would accrue after the death of brothers son.

When was your brother's granddaughter born?. Please furnish year of birth.

- After getting the share of father it will considered as your & deceased legal heirs self acquired property , and being self acquired property , you all having to sell the property as per respective wish. 

- Further, If your deceased brothers wife and son is ready to sell the property as well , then others consent is not needed legally , and question of consent of grand daughter not arise if class I legal heirs of your brother is alive . 

- The buyer having no knowledge of law of the land. 

The buyer is not the authority or law that he can dictate terms in the manner he may choose to.

The law is very clear that share of your deceased brother devolves on his own legal heirs alone and would not pass on to the next generation.

Therefore if the buyer is adamant about it you may politely turn away the offer made this buyer and look for a buyer who understands the  law properly and does not raises unnecessary objections without understanding the law.

It doesn't work like that no self acquired property can become ancestral in the above case

Dear sir,

Any property that you acquire with your own money, would qualify as your self-acquired property. Hence the property of your brother who died intestate  will be inherited by the legal heirs i.e your brother's son and his wife.

Thank you
