In short
Recognition is the process in which a father admits paternity of a child by signing a paternity certification at the Demographic Registry, or through a sworn statement before a notary public. There is a cost difference worth knowing in time: the internal revenue stamp is $20.00 if the recognition and the birth certificate amendment happen within 90 days, and $35.00 after 90 days. If the person being recognized is of legal age, they must appear in the sworn statement accepting the recognition. The process is carried out only at the Central Office in San Juan.
What is it?
The Demographic Registry defines recognition as the process in which a father admits paternity of a child by signing a paternity certification at the Demographic Registry, or through a sworn statement before a notary public. It is an administrative act with an effect on the birth certificate: amending the certificate is part of the same process, which is why the fees speak of “recognition and amendment to the birth certificate” as a single thing. There are also two related items the Registry charges for separately: the literal paternity certification to amend Social Security records, and the removal of Act #104 where applicable.
Who can do it?
The process is initiated by the father admitting paternity. One condition depends on the age of the person being recognized: if they are of legal age, the Registry states they must appear in the sworn statement accepting the recognition, meaning it is not a unilateral act in that case. The Registry also mentions bringing the Court Filiation Order, which points to situations where recognition follows a judicial process. If your case involves a dispute, a court order or doubts about filiation, that is a matter to consult with an attorney before going to the Registry.

Cost
In internal revenue stamps, and it depends on elapsed time: $20.00 for the recognition and amendment to the birth certificate within 90 days, and $35.00 after 90 days. There are two related items the Registry charges separately: $20.00 for the literal paternity certification, which is used to amend Social Security records, and $20.00 to remove Act #104, where it applies to your case. The difference between the $20.00 and the $35.00 is the only part of the cost within your control, and only if you act within the 90 days.

Step by step
Step 1: Count the 90 days
It is the only point where you can save money in this process, and only if you act in time. The Registry charges $20.00 for the recognition and the birth certificate amendment within 90 days, and $35.00 after 90 days. If you are inside the window, resolving it now costs less; if it has passed, there is no way to recover the difference.
Step 2: Choose the route: certification at the Registry or a sworn statement before a notary
The Registry names both: signing a paternity certification at the Demographic Registry, or making a sworn statement before a notary public. Which suits you depends on your case and on whether the other party can appear, so it is worth asking before moving paperwork.
Step 3: If the person recognized is of legal age, coordinate their appearance
The Registry is specific: if the person recognized is of legal age, they must appear in the sworn statement accepting the recognition. So the father’s will alone is not enough; the person being recognized must be present and accept. Coordinating that appearance is usually what takes longest when the child is already an adult.
Step 4: Gather the original birth certificate and the court order
The Registry requires the birth certificate to be an original, not a copy. It also mentions bringing the Court Filiation Order. If you have no order because your case did not go through court, ask directly at the Central Office before going, rather than discovering it at the counter.
Step 5: Buy the stamps that apply, including those for the additional items
Beyond the recognition stamp, work out whether you need the literal paternity certification to amend Social Security records, which is another $20.00, or the removal of Act #104 where applicable, another $20.00. Knowing beforehand saves having to step out for another stamp mid-process.
Step 6: Go to the Central Office in San Juan
Like late registration, this process is not done at a local office: the Registry states it is carried out only at the Central Office, Metro Center, Calle Mayagüez #5, San Juan, PR 00910.
Where to do it
Only at the Demographic Registry’s Central Office: Metro Center, Calle Mayagüez #5, San Juan, PR 00910. The sworn statement, when that is the chosen route, is made before a notary public.
How long it takes
What to do if something goes wrong
If the 90 days have passed, the process is still possible: what changes is that the stamp goes from $20.00 to $35.00. If the child is of legal age and will not or cannot appear, that is a real obstacle, because the Registry requires their appearance accepting the recognition; there it is worth talking to an attorney about what alternatives exist. If your situation is not a voluntary recognition but a paternity dispute, the Demographic Registry does not resolve that: it is a court matter, and the Filiation Order the Registry mentions comes precisely from there. If beyond the surname you need to correct Social Security records, that is the literal paternity certification, a separate $20.00 stamp. And if what you want is for the child to be legitimated because the parents married after the birth, that is a different process at the same Registry. PRFácil does not file recognitions and does not provide legal advice; for a case with a dispute or a court order, consult an attorney licensed in Puerto Rico.
Common mistakes
- Letting the 90 days pass without knowing the stamp rises from $20.00 to $35.00 once that mark is crossed.
- Going to a local Demographic Registry office, when this process is carried out only at the Central Office in San Juan.
- Bringing a copy of the birth certificate when the Registry requires an original.
- Showing up without the person being recognized when they are of legal age and must appear accepting the recognition.
- Assuming recognition alone fixes Social Security records, when that is the literal paternity certification, with its own $20.00 stamp.
- Trying to resolve a paternity dispute at the Registry, which is a court matter.
Frequently asked questions
How much does recognition cost?
$20.00 in internal revenue stamps if the recognition and the birth certificate amendment happen within 90 days, and $35.00 after 90 days. If you also need the literal paternity certification to amend Social Security records, that is another $20.00, and removing Act #104, where applicable, another $20.00.
My child is already an adult. Can I recognize them?
The Registry contemplates that case, but with one condition: if the person recognized is of legal age, they must appear in the sworn statement accepting the recognition. In other words, they must agree and be present.
Do I need to go to court first?
The Registry mentions bringing the Court Filiation Order among what to bring, which points to cases that go through court first. If yours is a voluntary recognition with no dispute, ask directly at the Central Office what applies to your situation before assuming you need litigation. And if there is a dispute, consult an attorney: that is not resolved at the Registry.
