We'll also discussion situations like one member want to leave after formation, how can he get out?

Information such as the member(s) name, address and the percentage of the business owned is not required to be provided to the state of Delaware and therefore is not part of the public record. This information is kept on file internally within the LLC's Operating Agreement.

The LLC's Operating Agreement can be altered as needed by the members, without filing the changes with the state of Delaware. Some of the typical changes people make are the removal or addition of a member or the change in percentage of a member's ownership.

The LLC's Operating Agreement must be amended to reflect that a new member is now part of the LLC, or to reflect the removal of a member, and all current members must sign the newly amended Operating Agreement, but you are not required to file the amended Operating Agreement with the state of Delaware.

Global data keys services will not need to know of the change and neither will Delaware Division of Corporations, so there is no charge.
