1) check the building plans sanctioned by municipal corporation 

2) whether OC has been issued for only 16 flats or 20 flats 

3) you have to sue the seller to recover your money if construction is unauthorized 

Dear Client,

This depend on the agreement executed with 16 flat owners and plan passed by municipality, how many flats were sanctioned. If it`s 16 than later flats are illegal. Neither am getting, when already proportionate share in land was registered with 1/16th each, how could builder was allowed by flat owners to construct more flats. Well, they them self not objected so, their share reduced to 1/20th but issue still same, if construction of 4 more flats in contravention of sanctioned plan than your property is at risk.

Check the sanctioned plan.

You can file a cheating complaint/FIR in the local police station against the builder. You can also file consumer complaint before the consumer court for deficiency of service.

Hello,

please check and let us know that whether the map for constructing those 4 flats was sanctioned by the authority or not?

regards

The builder has not only cheated you but he has cheated all the rest of the 16 owners. Lodge an fir against him in the local police station for fraud criminal breach of trust and forgery.

Regards 

Also file a case in the state consumer redressal forum immediately which will issue notice to the builder and impose costs on him.

. You can file a Police FIR, requesting investigation and charge-sheet, for offences like cheating, intimidation, fraud against the person, supported with all relevant supporting documents.

2. IF the Police does not take action, THEN you can file private criminal case u/s 156(3) Cr.P.C., in the local Magistrates court, seeking directions to the Police to investigate and file charge sheet. The said Person may come down for settlement.

Check approval whether it is not approved then you can file a complaint against him. 

1. A question like this cannot be answered unless the JV agreement which the builder executed with owner and local byelaws are perused. 

2. If you have been cheated then remedy is to file a criminal case of cheating under Section 420 IPC and also a civil suit for recovery of money paid to him as sale consideration but it will be a touch journey for you as the doctrine of buyer beware will apply against you with full vigour, 

Hi,

You are the legal owner of the flat and you need to verify the same from the authorities where the property is registered. 

Since you have purchased the flat by a registered sale deed, you dont have to be worried about it. In case the authorities find that this has been constructed violating the original approved plan and issue a notice to vacate or demolition, you may approach court and obtrain a stay order against the authorities and let the court decide while you can plead innocence about this.

1. As per the information mentioned in the present query, makes it clear that when the total area had already been divided between 16 existing flat owners stating in 1/16 ration then you how this can be further added with more four flats and given you 1/20.
2. Yes, you have been cheated by the builder by giving the wrong measurement as well as the ownership of flat which is not legal at par.
3. But, still before taking any criminal and civil action against him, I would advice you to check the exact measurement of the area and see if you can be allowed that percent of ownership.
