Spouses Danilo and Natividad, both Filipino citizens aged 38 and 35 respectively, wish to adopt Buboy, an 8-year-old child who has been living with them for the past two years after being abandoned by his biological parents. Despite diligent efforts by the assigned social worker, Buboy's biological parents could not be located. Danilo and Natividad filed a petition for adoption before the Regional Trial Court of Pasig City, following the procedure they were familiar with from older textbooks. The Regional Trial Court dismissed the petition outright, ruling that under Republic Act No. 11642, domestic adoption proceedings are no longer within the court's jurisdiction. Danilo and Natividad argue that courts retain concurrent jurisdiction over adoption cases and that their petition should not have been dismissed. Was the Regional Trial Court correct in dismissing the petition? (Bar 2026 Syllabus)
