Legitimation itself happens automatically the moment the child's parents marry — the PSA does not have to approve it. What takes time is getting that fact reflected on an official document: the parents must register an Affidavit of Legitimation with the Local Civil Registrar (LCR), which then endorses the record to the PSA for annotation, a process that commonly takes a few months from LCR filing to a PSA-annotated copy. Some PSA outlets offer a Premium Annotation Service that can release an annotated copy within about ten (10) working days once the endorsement is already on file, for a fee.
Many parents assume legitimation is something the PSA grants after reviewing an application. It isn't. Legitimation happens automatically by operation of law the instant the parents marry, if the child qualifies. The PSA's role is purely administrative: it annotates the child's existing birth record to reflect that the child is now legitimated, once the Local Civil Registrar has processed and endorsed the paperwork. Understanding that distinction explains why the “PSA part” of the process, while it can take a while, is not where the legal status of the child is decided.
Legitimation Happens by Law, Not by PSA Approval
Under Republic Act No. 9858, children born to parents who, at the time of conception, had no legal impediment to marry each other except that one or both were below eighteen (18) years of age, are legitimated by the parents' subsequent valid marriage. The law is explicit that legitimation “shall take place by a subsequent valid marriage between parents,” and it protects the child's legitimated status even if that marriage is later annulled — the annulment of a voidable marriage does not undo the legitimation that already took effect. This is different from a marriage that is void from the start, which never validly took place and so cannot legitimate a child through it.
Who Qualifies Under RA 9858
Republic Act No. 9858 specifically addresses one narrow but common situation: parents who were minors (below 18) when the child was conceived, with no other legal impediment to marrying each other, and who later marry once both are of legal age or with the required consent. Children legitimated this way enjoy the same rights as children who were legitimate from birth, including the right to bear their parents' surname and to inherit as legitimate children.
Legitimation Compared to Simply Acknowledging a Child
It is worth distinguishing legitimation from the more commonly used process of acknowledging a child born outside of wedlock. Under the law governing the use of surnames by illegitimate children (Republic Act No. 9255), an illegitimate child may use the father's surname if the father acknowledges paternity, without that acknowledgment changing the child's status from illegitimate to legitimate. Legitimation, by contrast, actually changes the child's civil status: a legitimated child is treated by law as if born legitimate, with the corresponding rights to a legitimate share in inheritance and to bear the parents' surname as a matter of legitimate filiation rather than mere acknowledgment. Families sometimes confuse the two because both eventually result in a birth certificate showing the father's surname, but the underlying legal effect, and the documents needed to get there, are different.
What Happens If the Parents Do Not Marry
Legitimation under Republic Act No. 9858 depends entirely on the parents marrying each other. If they do not marry, the child remains illegitimate regardless of how long the parents have been together or how involved the father is in the child's life, and the family's options are limited to acknowledgment and support rather than legitimation. This is a common source of confusion for parents who assume that simply living together for years, or having the father's name on the birth certificate, is enough to legitimate a child. It is not; legitimation under this law requires an actual, valid marriage between the parents.
Step 1: Filing the Affidavit of Legitimation at the LCR
The administrative process begins with the parents executing an Affidavit of Legitimation and having it registered at the Local Civil Registry Office of the place where the child's birth was originally registered. This is a purely local civil registrar transaction — there is no court petition involved, which is what makes legitimation under this law faster and cheaper than options that require judicial recognition. The LCR reviews the supporting documents (typically the child's original birth certificate and the parents' marriage certificate) and, once satisfied the requirements are met, annotates the local copy of the birth record and prepares it for transmittal to the PSA.
Step 2: The LCR-to-PSA Endorsement
This is usually the slowest link in the chain, and it is largely outside the family's control. After the LCR registers the affidavit and annotates its local copy, it must forward the annotated record to the PSA's civil registration system so the annotation is reflected on any birth certificate later requested nationally. How quickly this happens depends heavily on the individual LCR's workload, backlog, and how promptly it transmits its monthly batch of civil registry documents to the PSA. Families in cities with a high volume of civil registry transactions, or during peak filing periods, should expect this step to take longer than in a smaller municipality with a lighter caseload.
Step 3: Getting an Annotated PSA Copy
Once the PSA's central database reflects the annotation, an annotated birth certificate can be requested through the PSA's regular channels (PSA Serbilis outlets, PSA Helpline, or the PSA's online services). For families who need the annotated copy sooner and whose endorsement has already reached the PSA, some Civil Registry System outlets offer a Premium Annotation Service, which the PSA has stated can release an annotated civil registry document within about ten (10) working days of application, for a fee (around ₱255 per transaction at the outlets offering it). This rush option only shortens the PSA-side turnaround; it does not skip the earlier step of the LCR registering and endorsing the affidavit in the first place.
What Can Cause Delay
Common causes of delay include:
- Incomplete or inconsistent documents — discrepancies between the child's birth certificate and the parents' marriage certificate (misspelled names, mismatched dates) commonly send a filing back for correction before the LCR will register it.
- LCR backlog — some local civil registries process a high volume of annotations, corrections, and legitimations, and simply take longer to work through their queue.
- Delayed transmittal to PSA — the annotated record has to physically or electronically reach PSA's central database before any nationally issued copy will show it; this transmittal is not instantaneous.
- Requesting a copy too soon — ordering a PSA copy before the annotation has actually been posted to the central database will simply return the old, unannotated record.
Costs to Expect
Families going through this process should generally expect to pay for: notarization of the Affidavit of Legitimation, the LCR's filing and registration fee (which varies by city or municipality), a PSA copy of the child's birth certificate and the parents' marriage certificate to support the filing, and eventually a PSA copy of the annotated birth certificate once the annotation has posted — plus the optional premium fee if using the faster PSA annotation service. None of these fees are set at the national level in a uniform amount for the LCR portion, so it is worth asking the specific LCR handling the filing for its current schedule of fees before starting.
When to Consult a Lawyer
Most legitimation filings are straightforward enough for parents to handle directly with the Local Civil Registrar, particularly when the birth certificate and marriage certificate are consistent and complete. Legal advice becomes more valuable when there is a discrepancy between records, when the parents' marriage itself has any complication, such as a previous marriage that needs to be shown as validly dissolved beforehand, or when the LCR raises an objection to the filing. In those situations, a lawyer can help identify what additional proof the LCR or PSA is likely to require and avoid a filing being rejected or delayed for reasons that could have been anticipated.
Keeping Copies Along the Way
Because the process passes through more than one office — the LCR first, then the PSA's central system, and sometimes a rush service on top of that — it helps to keep a personal file of every document submitted and every receipt or reference number issued at each stage. If a filing needs to be followed up on, having the LCR's registration reference and the date of transmittal on hand makes it far easier for staff to trace where a record currently sits, rather than starting the inquiry from scratch. This is a small habit, but it consistently saves families time when a particular request seems to be taking longer than the rest.
Frequently Asked Questions
Does legitimation under RA 9858 require going to court? No. Legitimation under Republic Act No. 9858 happens automatically upon the parents' subsequent valid marriage and is processed administratively through an Affidavit of Legitimation filed with the Local Civil Registrar; no court petition is needed.
Can a child be legitimated if the parents were minors when the child was conceived? Yes, that is precisely the situation Republic Act No. 9858 addresses: children whose parents had no legal impediment to marry each other except that one or both were below 18, who later marry, may have the child legitimated.
Does annulling the parents' marriage cancel the child's legitimated status? No. The law specifically states that annulment of a voidable marriage does not affect legitimation that has already taken place, so the child keeps legitimate status even if the parents' marriage is later annulled.
Is there a faster way to get a PSA-annotated birth certificate after legitimation? Once the Local Civil Registrar has already endorsed the annotation to the PSA, some PSA Civil Registry System outlets offer a Premium Annotation Service that can release an annotated copy within about ten (10) working days for a fee; it does not shorten the earlier LCR registration and endorsement steps.
