One person in the building is encroaching on the garden space and parking area. Initially all flat owners allowed him to park . Now he is claiming the are is his . Also the ground floor has a garden which we all used to visit. He is claiming that as well. He started parking around 20 yrs ago. All other flat owners are paying property tax and tahsildar's tax etc. How can we get it removed ? Property card is also in the name of individual flat owners. We are not a regd society ? Can you advise how we can get the encroachment removed ? Is it possible that the encroachment has been regularised by the municipality ? What documents should we search for ?
