Yes, elderly parents can recover possession of their house in certain situations, especially under the Maintenance and Welfare of Parents and Senior Citizens Act, 2007 in India.
If parents have transferred their property to their children or relatives on the condition that they will be cared for, but the children fail to provide proper maintenance or neglect them, the parents can approach the Senior Citizens Tribunal to cancel the transfer and seek restoration of possession.
If the house legally belongs to the elderly parents and someone is occupying it without their consent, they may also take legal action through the appropriate court or authority to recover possession. They should keep ownership documents and evidence of neglect, harassment, or unauthorized occupation to support their claim.
It is advisable for elderly parents to consult a lawyer to understand the best legal remedy based on the ownership status and circumstances of the property.
