I got an agreement with a house-owner to purchase a house on stamp paper who took advance money in cash. But he has a bank-loan for that house which he can not repay. He is now asking more than agreed amount to get the house registered in my name which I do not want to pay. He is not registering it in my name and defaulting his loan instalments. I put my attendance on the last day of agreement in Sub-registrar's office.
What should I do now?
Under which sections I can file a case?
What are the consequences after filing a case?
