Existing partnerships that wish to take advantage of LLP status do not need to modify their existing partnership agreement, though they may choose to do so.  In order to change status, a partnership simply files an application for registration as a limited liability partnership with the appropriate state agency.  All states require disclosure of the partnership's name and principle place of business.  Some states also require, among other things, identification of the number of partners, a brief description of the business, a statement that the partnership will maintain insurance, and written acknowledgment that the limited liability status may expire.
