The consent of a member may be evidenced in any manner specified in writing in an operating agreement, but in the absence of a specification, consent must be evidenced by a written instrument, dated and signed by the member.
the deceased member's interest passes as described in subsection (d).
A transfer of an interest under this subsection is subject to IC 29-1-7-23 and does not affect the enforceability of a timely filed claim by a creditor against the estate of the deceased member. A legatee or an heir is automatically admitted as a member of the limited liability company under this subsection.
However, the assignee is not obligated for liabilities of which the assignee had no knowledge at the time the assignee became a member and that could not be ascertained from a written operating agreement.
