Section 741. Notice of rights; general provision

(a) At the initial
  appearance of a respondent in a proceeding and at  the  commencement  of
  any  hearing  under this article, the respondent and his parent or other
  person legally  responsible  for  his  care  shall  be  advised  of  the
  respondent's  right  to remain silent and of his right to be represented
  by counsel  chosen  by  him  or  his  parent  or  other  person  legally
  responsible  for  his  care,  or by a law guardian assigned by the court
  under part four of article two. Provided, however, that in the event  of
  the   failure  of  the  respondent's  parent  or  other  person  legally
  responsible for his care to appear,  after  reasonable  and  substantial
  effort  has been made to notify such parent or responsible person of the
  commencement of the proceeding and such initial  appearance,  the  court
  shall  appoint  a  law  guardian  and  shall,  unless inappropriate also
  appoint a guardian ad litem for such  respondent,  and  in  such  event,
  shall  inform  the respondent of such rights in the presence of such law
  guardian and any guardian ad litem.
    (b) The general public may be excluded from  any  hearing  under  this
  article  and  only  such  persons  and the representatives of authorized
  agencies admitted thereto as have a direct interest in the case.
    (c) At any  hearing  under  this  article,  the  court  shall  not  be
  prevented  from  proceeding by the absence of the respondent's parent or
  other person responsible for his  care  if  reasonable  and  substantial
  effort  has been made to notify such parent or responsible person of the
  occurrence of the hearing and if the respondent and his law guardian are
  present. The court shall, unless inappropriate, also appoint a  guardian
  ad  litem  who  shall  be  present  at  such  hearing and any subsequent
  hearing.
