Please tell me the procedure for legal action against the builder.
You should first serve legal notice on him demanding your requirements, if he fails to comply or do not respond you may file a case in the consumer forum seeking relief and compensation.
How much time will it take for all the proceedings?
Generally it may take upto two years, but is unpredictable.
I want to know if the contract is one sided by Builder will there be any way to get compensation though the contract doesn't specify any compensation?
The contract cannot be one sided, if it is so then this cannot be enforced in law so the situation is in your favor, go ahead after discussing with your lawyer.
Also, I want to know about Advocate in Faridabad who can guide me regarding this matter?
You have to search for one yourself.
