Regarding will which disinherits my friend's family members.

Please give some more information regarding the document executed by deceased in favour of  charitable organization (e.g. Will, gift or sale etc)

.How the deceased has acquired title of property?

Besides this the property is movable or immovable? 

In your brif you didn't clear that , whether such property is belog to ancestral or self earned one? Because the remedy available is kind of different by nature of the property. So clarify it. Second thing is that you have to clarify that what is the family religion?

Thank you for the responses, I am providing the information below:

The document was a will which left all property and savings to the charitable organization.

The property is immovable - a flat in Mumbai. And it is a self earned property not ancestral - he had purchased it through savings and housing loans which he had paid back fully prior to his passing away. Also my friend is Hindu, his family religion is Hindu.

Awaiting your further responses. Thank you.

Hence it is selfearned property, The property owner can dispose his property according to his wish and will and no opposition can be raised against his action.

Was the will Registered or unregistered ?

If unregistered then where are the witnesses of the will, .. ? Are both th witnesses alive? Where was the Will Document kept.

Has a probate been obtained by the cherity organisation who is the executor of the will, 

 

In case your friend is sure that will has been a  genuine document, then nothing much can be done.

Being self-acqired properties the deceased was well within his rights to dispose it off as he desired. Even if any one challanges the transfer in probate, it will not work, leading recent case of Priyambdha Birla's decided by Apex court.
