(1) Where the partnership commences business before it has been registered in the Commercial Register of the court in the district of which it has its seat, each limited partner who consented to the commencement of business will be liable for the partnership’s obligations incurred prior to its registration to the same extent as a general partner, unless their participation as a limited partner was known to the creditor. This provision does not apply insofar as section 2 or section 105 (2) provides otherwise.
(2) Where a limited partner joins an existing commercial partnership, the provision in subsection (1) sentence 1 applies accordingly to the partnership’s obligations incurred in the period between the limited partner’s joining and the registration thereof in the Commercial Register.
