sir, we live in 1st floor in chennai and we have a problem where there is a leak in ceiling. it is due to the upper flat bathroom but the owner is not letting in to inspect his unit. we are even ready to spend 50% of damages for his unit also . wih no support from builder (as this being a 12 yrs old flat /warranty over),assocation and upper flat owner, how do go with it. this has been going n for 3 months. some suggest to go for a mandatory injunction through court..what does it mean? how long will it take and is it legal the best/permanent option for this?. can i complaint to RERA against builder on this?
