This document discusses the process for cancelling or correcting entries in civil registries in the Philippines. It explains that any interested person may file a petition to cancel or correct an entry. Clerical errors and changes of name can be addressed via a summary proceeding, while other substantial changes require an adversarial proceeding. The petitioner, civil registrar, and any other interested parties must be notified. Oppositions may be filed within 15 days. The court can expedite the process and issue preliminary injunctions. If approved, the civil registrar will annotate the court's judgment in records.
