Builder not paying back my money.

Hello, I did a banakhat with the builder 6 year ago and paid him 4 lac rupees for 2 BHK flat in Ahmedabad. He sold me house on 7th floor promising that he will install lift in 6 months. He never installed lift and so I never proceeded for the remaining payment of 18 lacs. My parents where having trouble climbing 7 floor stairs and also we didn't had any electric meter. Till now building secretary was helping us by giving us the electricity using an empty house meter. I know it is not legal. But we didn't had any option. And after couple of years, we didn't had that also. So I purchased another flat somewhere else and locked this one. My furniture was as it is inside. Builder said he will give me 4 lacs money back and then I will remove all my furniture and hand over the flat to him. He never paid and infact his few chequre got bounced. Now 2 weeks ago someone else came and broke the lock and locked the door using his lock. I came to know that builder has sold this house to someone else. My furniture is still inside and now I don't have access to the flat. I asked the builder for payment and he keeps on postponing the payment. Please help me. What should I do? What is my stand in this? How can I get my money back from the builder? Or can I brake the lock someone else has put? If I want to live there then is there any way I can get a legal electric meter on my name? I asked Torrent power and they said they will install meter only when you have proper property papers. And I have only banakhat.. Thanking you Manoj Read more at: https://www.lawyersclubindia.com/experts/modify_message.asp?entry_id=800432
