[1] Consistent with the mandate to liberally construe a section 388 petition in favor of granting a full hearing on the merits, we assume the truth of the petition’s allegations, where not directly contradicted by incontrovertible facts in the record. (In re Marilyn H. (1993) 5 Cal.4th 295, 309-310 [a section 388 petition must be “liberally construed in favor of granting a hearing to consider the [petitioner’s] request” and the petitioner “need only make a prima facie showing to trigger the right to proceed by way of a full hearing”].)

[1] Section 366.3 provides in relevant part: “Following establishment of a legal guardianship, the court may continue jurisdiction over the child as a dependent child of the juvenile court or may terminate its dependency jurisdiction and retain jurisdiction over the child as a ward of the legal guardianship, as authorized by Section 366.4. If, however, a relative of the child is appointed the legal guardian of the child and the child has been placed with the relative for at least six months, the court shall, except if the relative guardian objects, or upon a finding of exceptional circumstances, terminate its dependency jurisdiction and retain jurisdiction over the child as a ward of the guardianship, as authorized by Section 366.4.” (§ 366.3, subd. (a).) Section 366.4, subdivision (a) states that “[a]ny minor . . . for whom a related guardianship has been established pursuant to Section 360 . . . is within the jurisdiction of the juvenile court.” For termination of a relative guardianship, section 360 provides, “Sections 366.4 and 388 shall apply to this order of guardianship.” (§ 360, subd. (a).)
