Our building is registered under Apartment act. There are 8 apartments.The apartment has completed 25 years.For nearly 15 years ago wear and tear of the building began,but we have sorted it amicably.But out of 8 flat owners 2 flat owners have seepage in their bathroom and toilet from the upper flat, until then the flat owner whose flat,s bathroom or toilet was leaking repaing it by his own expenses,but now other two apartment owners are insisting that henceforth the seepage problem should solved by two aparment holders by equal contribution.The other flat holder is not agreeing with this. His contention is that if one is the sufferer and the fault is of uppar flat owner then why other flat owner should bear 50% expenses and stop this troble of water leakage.
What is the legal answer for this?
