I had entered into into an Agreement to Sale for selling a part of my plot (with an independent house) in Odisha. This is a residential unit and the buyer initially verbally confirmed that he was going to use that for a dwelling house for which he was raising home loan from State Bank. In the meantime, in my absence (I live outside India) he has gone ahead and made structural changes and converted the house to accomodate a pathology lab. On mails also now he is mentioning that he will set up a Pathology lab.
I do not want this Lab there as this is a Residential Zone of the Development Authority and also will result in fall in property valuation of rest of my property.
What are the remedies available to me?
