Short answer. Yes. Because a paternity judgment changes your child's filiation, correcting the birth certificate to match it is a substantial correction, not a clerical one. RA 9048 and RA 10172 let the local civil registrar fix clerical errors, first names, birth dates, and sex entries administratively, but a judicial determination of filiation still needs a Rule 108 court petition.

What Rule 108, Section 2 covers
Rule 108, Section 2 lists the civil registry entries that may be cancelled or corrected through a court petition, and it names judicial determination of filiation as one of them, alongside births, legitimations, acknowledgments, and adoptions. A court judgment establishing that a particular man is your child's father is exactly this kind of entry — it changes filiation, which the civil registrar's records must then be made to reflect. Because the change did not come from a clerical slip but from a court's own finding after a case was heard and decided, the law routes it through the courts rather than through a simple counter transaction at the local civil registry office.
Why this is a substantial correction, not a clerical one
Republic Act No. 9048 and Republic Act No. 10172 opened an administrative shortcut at the local civil registrar for clerical or typographical errors, a change of first name, and the day, month, and sex entries where the mistake is clerical. Filiation is not on that shorter list. A birth certificate entry that reflects who a child's father is goes to the child's civil status, and that kind of substantial correction still requires the judicial proceeding under Rule 108. Because you already hold a court judgment establishing paternity, your situation is precisely the substantial correction this rule contemplates, not the narrow clerical-error route the administrative law created.
What the petition is for
A Rule 108 petition asks the court to direct that the civil registry entry be corrected on good and valid grounds — here, the existing judgment that already determined paternity. The petition does not ask the court to decide paternity again; that has already been resolved. Its purpose is to carry that judicial finding into the civil registry record itself, so the birth certificate on file with the civil registrar and the Philippine Statistics Authority matches what the court has already established. Because a correction of this kind affects civil status, parties with an interest in the entry are typically given the chance to be heard before the correction is ordered.
Talk to counsel about your specific record
Whether a Rule 108 petition is the right next step, and how the existing paternity judgment should be presented to support it, depends on the wording of that judgment and on what exactly is entered — or missing — on the child's current birth certificate. A lawyer can review the judgment and the civil registry record together and advise on how the correction should be framed for the court.
