1) What would be my legal options if Builder will not refund the amount within a month anf what would if he takes more than a year and what would if he do not refund .
You can initiate legal process by first issuing a legal notice and then dragging him to either consumer forum or civil court.
2. What would be a legal option if builder will take a time to refund the amount and if he won't pay the interest to bank till the time the final loan amount is closed .
The builder will face problems for cheque bounce case if his cheque to bank was bounced.
For refunds you can initiate legal process for recovery.
3) After consumer court , can builder challenge it to high court or shall I got to Supreme court . apology its just I am a middle class person and not earning much . I have spent all my earnings and I don't see any way forward . I have my ailing mother and 8 month old kid . you can even imagine the torture I am going through . From last 1 year , I have spent all my weekends either going at project site , either meeting with builder .
Please suggest me what is the way to get the money refunded from builder as early as possible
What he can do cannot be predicted.
You first initiate legal process through consumer court, dont worry about his further action at this stage itself.
First prosecute him properly and manage to get a verdict agaisnt him, let him decide what to do next.
