Under Section 69 of the Indian Partnership Act, 1932, which of the following disabilities does an unregistered firm suffer? 

Section 69 imposes three disabilities on unregistered firms: (i) no suit to enforce a right arising from a contract or a right conferred by the Partnership Act can be instituted in any court by or on behalf of any person suing as a partner in a firm against the firm or any person alleged to be or have been a partner; (ii) no suit to enforce a right arising from a contract can be instituted by or on behalf of a firm against any third party; and (iii) the firm or its partners cannot claim a set-off or other proceeding to enforce a right arising from a contract in a suit or proceeding instituted against the firm by a third party. However, non-registration does not affect the validity of the partnership itself, its right to own property, or rights of third parties against the firm. The disability is procedural, not substantive.
