"Members
Whether holding meetings or taking action by written consent, valid decisions by the members require a majority of the membership interests. This is not necessarily the same as a majority of members. For example, if there are 4 members each owning 25% of the membership interests, then 3 members would constitute a majority. However, if there are 4 members, 1 of which owns 60% of the membership interests, then that 60% member alone would constitute a majority. The "majority" is not by number of people, but by percentage of interests."

Transfer and Assignment of Interests
The operating agreement you may create using this website states as a general rule that a transfer or assignment of membership interest (or any part of it) is void unless all the members unanimously agree to it in writing. This is a modification of the default rule provided by California Corporations Code section 17301(a), which allows a transfer of a membership interest or economic interest if a majority in interest of the members not transferring their interests consent to it. If you wish to create an operating agreement that allows for transfers of interests by majority vote, do not use this website.
