The donor and donee may agree that on the happening of any specified event which does not depend on the will of the donor a gift shall be suspended or revoked; but a gift which the parties agree shall be revocable wholly or in part, at the mere will of the donor, is void wholly or in part, as the case may be.

Save as aforesaid, a gift cannot be revoked.
>>> Maintenance and Welfare of Parents and Senior Citizens Act, 2007
( AS published in Gazette)
23. Transfer of property to be void in certain circumstances
Where any senior citizen who, after the commencement of this Act, has by way of gift or otherwise, his property, subject to the condition that the transferee shall provide the basic amenities and basic physical needs to the transferor and such transferee refuses or fails to provide such amenities and physical needs, the said transfer of property shall be deemed to have been made by fraud or coercion or under undue influence and shall at the option ofthe transferor be declared void by the Tribunal.
Where any senior citizen has a right to receive maintenance out of an estate and such estate or part , thereof is transferred, the right to receive maintenance may be enforced against the transferee if the transferee has notice of the right, or if the transfer is gratuitous; but not against the transferee for consideration and without notice of right.
If any senior citizen is incapable of enforcing the rights under sub-sections (1) and (2), action may be taken on his behalf by any of the organisation referred to in Explanation to sub-section (1) of section 5.
