Any individual called to testify before a grand jury or special inquiry judge, whether as a witness or principal, if not represented by an attorney appearing with the witness before the grand jury or special inquiry judge, must be told of his or her privilege against self-incrimination. Such an individual has a right to representation by an attorney to advise him or her as to his or her rights, obligations, and duties before the grand jury or special inquiry judge, and must be informed of this right. The attorney may be present during all proceedings attended by his or her client unless immunity has been granted pursuant to RCW 10.27.130. After immunity has been granted, such an individual may leave the grand jury room to confer with his or her attorney.
