- As per rule, a Housing Society is a body that represents interest of people living in a community or a society and the association is responsible for managing day-to-day problems of the residents, organising events, managing facilities in the apartments and complexes and safeguarding the rights of the unit holders.

- Further, as per law, an housing society should follow that: 

1. Senior Citizen should remain integrated in society and participate actively in the formulation of policies which effect their well-being.

2. Senior Citizen should have access to health care to help them maintain the optimum level of physical, mental and emotional well being.

3. Senior Citizen should be able to pursue opportunities for the full development of their potential and have access to educational, cultural, spiritual and recreational resources of society.

4. Senior Citizen should be able to live in dignity and security and should be free from exploitation and mental and physical abuse.

- If the association is not adopting these laws, then he should report the Secretary/registrar of the society.

-  Hence, your parents being senior citizens , can also lodge a written complaint under the Senior citizen Act as well,  if the society is implementing unfriendly rules which are creating hardship to senior citizens. 

- As i mentioned above i.e. before the Secretary/management committee

- If no response, then forward that compliant to the Registrar of the Society 

- Further, your parents can also send that compliant to the DM or Higher police official of their jurisdiction under the Senior Citizen Act.
