My grandma gave me power of attorney pertaining to her self-earned property (house) . I used the same and got the house registered through sale deed on my mother's name. The sale deed & power of attorney were both registered at registrar office.
Now I want to know whether any of her children (grandma children or grandchildren) can claim share on this house (viz registered on my mother's name).The house was not ancestral house.
Your question is can it be challenged? Yes it can be. Aggreieved party has right to challenge it. Now the question it whether sale deed can be set aside or not? Then the answer is,It is based upon facts and circumstances of the case.
There is no certainity. Any sale deed can be challenged, if it is subsequently found that it was obtained through fraud, forgery, misrepresentation or undue influence, and the affected party can seek court to set aside that sale deed. Nothing can be assured in case they are tainted documents
Your mother or you (as GPA Holder) have to file a suit for perpetual injunction and has to file an interim application for tempotary injunction restraining the tresspassers. You have name all the persons who are trying to encroach as defendants. If they already tresspassed, you can file a criminal case against them. Since you reside in the state of AP which the neighbouring state of Telangana, you can contact me for detailed clarification.
