How to go about reversing will

Always avail the services of a local advocate when the issue is complicated, as mutation records, how and why you think the will as invalid, whether both brothers in the past admitted the will and presented it to any authority for mutation etc., the way of transfer by you to your father etc., are material facts that can be studied only through documents.

Facts posted are less than precise and are confusing. Hence no meaningful suggestion is possible.

A person can make a WILL for his personally owned properties only, he can not make a WILL for his ancestral properties. Every direct descendent of the ancestors will have an equal share in the ancestral properties.

Considering complicated facts which require further probing, you may better take guidance from a well conversant Lawyer  at your place.

Thank you for responding, i think you don't need to make a will for your ancestral property it gets transferred to successors. I may be wrong or may not have full knowledge on this but that's what is logical that a father can divide his self acquired property as per his wish but  the property which he acquired from his father should go to every child. Generally girl child give no objection letter and property is transferred to boys.

Father wrote the will and personally submitted it to the authorities, later my brother submitted  death certificate of my father and I was told it's transferred on our name very recently.

I got allotment of the land, all permissions, connections(water,elect etc) and completion was taken on my name, later I transferred the house to my father thru "family transfer" application by paying ₹3000 fee  to authorities and they re-alotted the plot to my father..

What prevents you from posting simple facts instead of assumptions, presumptions and subjective opinions?

Someone asked why I think will is invalid so I tried to explain that.

What facts you want to know I am not sure, simple is father wrote will for ancestral property leaving my sister's and no will for the property which he owned. Sisters are not going against father's will so brother thinks he can get half in the house as well leaving his sisters once again. Only way he can be brought to see the reality is when the will is made invalid, Sisters are with truth, which is house is mine, ancestral property should be divided between me and brother.

First of all, why and how do you consider the property tp be ancestral?

Sir I said land which is ancestral is already divided between we two brothers by "will" written and submitted by my father before his death. Then in a city I bought a house in 2005 which I  gave to my father in 2007, this is now my father's self acquired property and not ancestral, this will be and should divided between five of us,  only thing is greedy brother is interested to get half in this as well. And sisters who are fair and don't want anything in this,  are giving me their share , just asking to get the idea if it's possible to get that will cancelled or whatever so that my brother can come in reality and accepts he is owner of 1/5 in the ancestral property and the house my father owns.
