(1) If several joint owners are entitled to one undivided share, they may exercise the rights arising from that share only jointly.
(2) They are jointly and severally liable vis-à-vis the company for the payments to be effected against the share.
(3) Legal acts which the company must perform vis-à-vis the owner of the share are, insofar as there is no joint representative for the joint owners, also effective if they are only performed vis-à-vis one of the joint owners. This provision applies to several inheritors of a shareholder only in relation to legal acts performed after one month has elapsed since devolution of the inheritance.
