I honestly doubt title of Land .
I doubt whether construction is legal ? .
I doubt whether all documents are porperly made?
Since documents are private documents I feel better show to some good Property Advocate from your area . Since all property law of Madhya Pradesh, Town Planning Act whether followed or not required to be checked and make clear whether make out whether you are legally cheated or not.
I doubt legal cheating ( I saw yesterday Madhya Pradesh Town Planning Act)
Although from Maharashtra , Madhya Pradesh Town Planning act was similar to Maharashtra I felt , so many laws are similar and with understanding legal properties all over India I feel there is legal problem too
1) Visit Lawyer who is good in Property law personally with documents
2) Show him documents and ask whether every thing proper , whethere you are legal owner , whether construction legal . Whether proper title in land (even if it is society)
3) Tell him to check every thing and revert back what he says then I will tell
4) Madhya Pradesh papers can not be properly interpreted by Maharashtra person like land record , etc. So better show documents to Local lawyer then ask what he says then I will tell further
