Corporate demat account registration

can we open a corporate demant accout if our company is regestered as one person company

No. You will be going against the object clause in your MOU.

i didnt understood what you want to say

A company can’t indulge in any trading or investing activity unless it is registered as a NBFC.

oh man you are going so deep there is nothing like that once read some article on corparte demant account or watch some vedios you will understand

You cannot even incorporate a company having objective of investing or trading. Demat account is totally secondary. I was just telling you, what you are planning wont work. Then its your wish.

And talking about reading articles and watching videos, I have read whole of Companies Act at least 5 times.
