Hi,
You would be filing form 1, for incorporation. If you go through this form you will come across a sentence on page 2-3 which states
“If already a director or promoter of a company(s), specify details of such company(s) (In case director or promoter in more than three companies, attach separate sheet as an optional attachment)”
You will not need to furnish a board resolution, you will only require to attach a sheet comprising of a list of and details of the company wherein the proposed director or promoter is already a promoter or a director as an attachment to Form-1
Best Regards
