No less than forty-five (45) days prior to the hearing date, the clerk's office shall send notice of the hearing to the Department, to the petitioner, if different from the Department, to the child or young adult's attorney, and unless the parents' rights to consent or receive notice of any petition for adoption, custody, guardianship or other disposition of the child have been dispensed with, or the parents have signed voluntary surrenders or the subject of the hearing is a young adult, to the parents, by mailing to their last known addresses, or if the parents are represented by counsel, to their attorney(s) of record. Such notice shall inform the parties of the date, time, and location of the hearing, of their right to counsel pursuant to G.L. c. 119, § 29, and of the right to file objections pursuant to Rule 6. If a case is scheduled for permanency hearing and the child or young adult is no longer in the care or custody of the Department, the Department shall notify the court and all parties, or if the parties are represented by counsel, the attorneys of record, and the court will take the case off the hearing list. The time for notice provided in this paragraph shall not apply if the court has determined that reasonable efforts to reunify the family are not required pursuant to G.L. c. 119, § 29C.
