To my knowledge, the provisions of Senior Citizen's Act are prospective, not retrospective. The enactmentState was notified on 31st December, 2007 and has come into force on the date as appointed by the respective State Government.
As such, in the instant case, there is no option for seeking revocation of the gift. The only option is to seek maintanance in terms of Section 4 -
Section 4. Maintenance of parents and senior citizens.
(1) A senior citizen including parent who is unable to maintain himself from his own earning or out of the property owned by him, shall be entitled to make an application under section 5 in case of--
(i) parent or grand-parent, against one or more of his children not being a minor;
(ii) a childless senior citizen, against such of his relative referred to in clause (g) of section 2.
(2) The obligation of the children or relative, as the case may be, to maintain a senior citizen extends to the needs of such citizen so that senior citizen may lead a normal life.
(3) The obligation of the children to maintain his or her parent extends to the needs of such parent either father or mother or both, as the case may be, so that such parent may lead a normal life.
