There are 2 partition deed executed in 2008 and 2011 between 4 heirs of my father (his mother, my mother and 2 children). One deed for self acquired property and the 2nd deed for ancestral property .
1st deed for self acquired property executed in 2008:
My father's mother and my mother had given up their shares to both children through the partition deed.
2nd deed for ancestral property executed in 2011:
My father's mother alone gave up her share to my mother and both children through partition deed.
Now my father's mother aged 93 under the influence and with the help of her daughters (father's sisters) has filed an injunction to get back 1/4 share stating both the partition deed were executed by fraud means and that she was not in her right mind during registration of the deeds (which is a false accusation).
All the fees for registration were paid by the children for both deeds and paid tax till date.
Are these partition deed revocable?
