Admittedly, it is only that a legal notice has been issued; the SRO has not taken any action on the said notice. As such, is not the query premature, especially when you are raising the query based a third party's version?
You have been informed by the third party that "to take legal action on my friends family members under fraud, cheating and misrepresentation in execution of registration." it could very well be that your friend has, in deed, indulged in such acts. If so, he should face the consequences. It appears that he has prevailed upon you to make misrepresentation on this platform so that the various participants, out of their good will, offer so many suggestions which could be useful for your alleged friend in protecting himself against his wrongdoing.
Moreover, has your alleged friend provided access to the so-called legal notice? In all probability, NO; in fact, it is unlikely that there is no such legal notice.
You had, in another thread, informed us as follows:
"I am a social person and many people connect me with different legal issues in my family and friends therefore i just try to aware them the legality through this wonderful platform and i am also enhancing my knowledge in the world of Law."
You are welcome. We would try our level best in offering in meaningful suggestions. However, there is a corresponding and strict obligation on your part to confirm the veracity of the information provided by third person. If not, this platform would be rendered a safe haven for speculative posting and would be brought down a rung or two in its stature as a "wonderful platform".
