A father gifted property to his son via a gift deed. Following the son's sudden death, the son's wife wishes to sell the property and evict the father. Generally, a gift deed cannot be unilaterally cancelled by the donor. However, if the father is a senior citizen and the donee (his son) failed to provide care, he may be able to petition for revocation under the Senior Citizens Welfare and Maintenance Act 2007. Legal advice is crucial as rights depend on applicable personal laws and the gift deed's terms.
