For LLP 11 form you just need to know whether turnover of the LLP for the financial year has exceeded Rs.5 Crore or no. If it exceeds Rs.5 Crore, then certification from a Practising Company Secretary is required. If it does not exceed Rs. 5 Crore then certification of Designated Partner of LLP will do.
Further you need to know, contribution amount as specified in LLP Agreement by the Partners has actually been bought in the business or no. If PCS certification is required, it is recommended to get a proof (Bank Statement of LLP) indicating that the amount of contribution has been actually bought in the business by Partners.
Please note that you have to attach a document specifying Details of LLP and Company in which Partners of LLP is a Director/Partner. The format has been enclosed.
