Partners generally have personal liability for partnership obligations, with statutory nuances, and authority/representation and tax transparency require careful design. It can be used to hold or manage jointly owned assets in appropriate cases, but does not itself create condominium status or a housing subsidy entitlement. Public programmes often specify eligible legal applicants; do not assume an S.s. qualifies. Separate partnership interest from title registered to the partnership and any household occupancy rights.
