Significant beneficial ownership declaration requires detailed disclosure of direct and indirect holdings and partner status for LLP contributions. Form LLP BEN-1 requires a declarant holding significant beneficial ownership in an LLP to provide identity particulars and to quantify rights arising from the holding: percentage by contribution, voting rights, distributable profits, and any exercise of control or significant influence (supporting agreements to be attached). If holding is indirect through a partner entity, the declarant must state the partner type and registration number, partner name and address, percentages attributable through that partner, and the declarant's status within the partner; disclose any direct holding; and sign with date, place and attachments.
