My mother got the property transferred in her name by declaring in DDA that after my fathers death she has only two kids . wheareas we were 4 . and grandmother was also alive . she got relinquishment deed signed by two kids only . and gave affidavit also in the DDA for the same .now she has given eviction notce to me . i am residing in the property for 40 years . but my signed relinquishment deed is being quoted as to my giving up my share in the property am i liable to vacate the property .. is my relinquishment deed valid which is signed only by me and one of my sister .
File complaint against the person who on oath, namely in her affidavit stated falsely about the number of children and mother of the deceased who had right in the property of the deceased. Relinquishment deed was not given by all legal heirs.
Request for cancellation of transfer made by DDA. You even withdraw your own relinquishment deed.
File suit for partition of the property, seeking your share in the same.
All this will put enough pressure on the other party to settle dispute amicably.
Details are missing. Based on the contents of query it seems that mother has committed wrong and has cheated by concealing the facts and also executed false information. Your grand mother was also entitled to share in your father's property. You can revoke relinquishment deed, make representation to SDA and necessity arise file necessary suit.
