Next you need to understand the three membership documents which you will autograph and affirm: DOI-Declaration of Independence, DUR-Declaration of Unalienable Rights, JCO Jural Covenant of Office.  The DUR and JCO require witnesses, and the JCO requires a pledge affirmed by the Moderator in a state GJA meeting.

DOI-Declaration of Independence
DUR-Declaration of Unalienable Rights
JCO Jural Covenant of Office

In the member documents you are affirming upholding the Organic Constitution and the Covenant of your state.  The Covenant is a common law express trust which sets up and controls the state republican form of government.  It is rather lengthy and contains definitions of all the major words used, so that there is no question of their meanings.  The RD17 Annotated Covenant provides explanations.

Covenant of New State

When there are at least thirteen GJA members domiciled in a county they may form a county jural assembly (CJA) to provide oversight of county and local government.  They put in place a County Settlement Covenant, in accord with the Covenant of the state, for control of county government.  A very similar document is put in place for the territory, acting like one big county.
