Can i nominate a retired doctor as a director

Hi,

I am starting my new healthcare company and thought I should nominate a couple of non-voting retired Doctors and university Medical Professors as board members, so that they could help me in strategy and also could help lifting  integrity of the company when I approach various stake holders.

However I am not sure what Corporate Law rules to follow so that we don't have any issues going forward.  Also do these non-voting directors should have their DIN no?

Please anyone can help me with some ideas?

Appreciate your replies.

Thanks, Susmitha
