Short answer. Yes, but only if the primary evidence — a birth record, court judgment, or a signed written admission — is absent. Article 172 of the Family Code allows legitimate filiation to be proved by the open and continuous possession of the status of a legitimate child when those primary documents do not exist.

The two tiers of proof under Article 172

Article 172 creates a two-tier system for proving legitimate filiation. The first tier — documentary and primary — consists of the birth record in the civil register, a final court judgment, or a signed admission of legitimate filiation in a public document or a private handwritten instrument. These are the strongest and most direct forms of proof. The second tier applies only in the absence of these primary documents, and it includes the open and continuous possession of the status of a legitimate child and any other means allowed by the Rules of Court and special laws.

What open and continuous possession of status means

Possession of the status of a legitimate child is not a legal fiction — it refers to how the parent and the extended family actually treated the child in daily life. The hallmarks typically include being introduced and known as the parent's legitimate child, bearing the family surname, being supported by the parent, living with the family, being included in family events and decisions, and being recognized in correspondence and family documents. The possession must be open — visible to others, not hidden — and continuous — spanning a period of time, not just occasional instances.

Why the absence of formal acknowledgment is not necessarily fatal

Filipino families sometimes fail to register births properly, or documents are lost in disasters or displacement. Parents may die before formally recording a child's status. Article 172 anticipates this reality: the law does not require formal acknowledgment as a prerequisite for legitimate filiation when the circumstances of the family relationship speak for themselves. A child who was raised openly as a legitimate child of the family, supported, educated, and recognized by the parent and relatives as such, is not left without recourse simply because no paper was signed.

How to present this in a legal proceeding

Proving possession of status in court involves gathering evidence of the relationship over time — photographs, school records listing the parent, letters, testimonies from family members, neighbors, teachers, or priests who witnessed the parent treating the child as legitimate. The more consistent and long-standing the evidence, the stronger the case. This is often introduced through a petition for recognition of legitimate filiation or in the context of an estate proceeding where the child's right to inherit is at issue. The standard of proof is preponderance of evidence, and the outcome depends heavily on the specific facts of each family's situation.
