Hi,
Share transfer form 7B can be of state either where transferror or transferee resides OR where 7B is executed. It has nothing to do with ROC of the state where RO of company is situated.
You can very well use share transfer form 7B stamped by any ROC.
Lets take an eg.
Suppose you have to transfer physical shares of Reliance Industries Ltd having its RO at mumbai and transferor and transferee are in jaipur so will they obtain form 7B from mumbai. Practically it is illogical and not possible in many cases. Transferor and transferee in this case can very well use share transfer form 7B stamped by ROC of Rajasthan since form 7B is executed in jaipur.
With Regards
