An application for registration, renewal, amendment or withdrawal may be amended or corrected by filing a certificate of amendment in duplicate, executed in the manner of an initial application, and accompanied by the required filing fee. In the case of a domestic limited liability partnership, the filing fee for an amendment is $10, plus, if the amendment increases the total number of partners, $200 for each partner added by the amendment. In the case of a foreign limited liability partnership, the filing fee for an amendment is $10, plus, if the amendment increases the total number of partners in this state, $200 for each partner added by the amendment, but not to exceed $750. The secretary of state has promulgated forms for amending the registrations of domestic and foreign limited liability partnerships; however, use of such forms is not mandatory. See Forms 722 and 407, respectively, available at http://www.sos.state.tx.us/corp/forms_boc.shtml.
