Dear Querist
All things are practicly possible but less value if there is any written documents, written documents will enforceable by law and you have to pay the amount as per the terms and condition of mou.
Forcefully possession of flat is illegal.
When you may 64 lacs then why do you go to litigations for 2 lacs or other legal amount which you legally bound to pay.
Settled the matter amicably and get your dream home.
