In short
A name or surname change for someone born and registered in Puerto Rico can be done two ways: by petition before a Superior Courtroom of the Court of First Instance, or before a notary attorney as a non-contentious matter under Act 282-1999. Through the court it is an ex parte process — you sue nobody — but it requires a file assembled from five different agencies: an original birth certificate, a CRIM negative-debt certification, a criminal record certificate, an ASUME compliance certification and a Hacienda negative-debt certification, plus $78.00 in stamps. Everything is filed in duplicate: one set to the court and one to the Prosecutor’s Office, which has 10 days to object. And it does not end with the resolution: you must request a certified copy, take it to the Demographic Registry, and then update Social Security, DTOP and the State Elections Commission.
What is it?
The Demographic Registry keeps the records of births occurring in Puerto Rico. When someone wants to change, add or modify the name or surname they were registered under, they follow the procedure in Act No. 24 of 1931, the Demographic Registry Act. Before the court it is a voluntary-jurisdiction matter: you file a petition and submit to the court’s authority without suing anyone, which is why it is called ex parte. The surname change this procedure covers refers to corrections of the order of surnames, when there is more than one, or errors made at registration. It is not the route for changing surnames through a filiation process, which is a different thing with its own guides here.
Who can do it?
It can be requested by people born in Puerto Rico who were registered in the Demographic Registry. The sworn statement accompanying the petition certifies two things: that everything stated is correct, and that the interest in changing the name is not to evade any civil or criminal liability.

Step by step
Step 1: Decide: court or notary
The name change can be done before a Superior Courtroom of the Court of First Instance, or before a notary attorney as a non-contentious matter under Act 282-1999, which expressly covers the change, substitution, addition, deletion, correction or modification of names or surnames in the Demographic Registry. This guide describes the judicial route; the notarial one carries fees the Judiciary does not publish.
Step 2: Assemble the file: five agencies
This is the real work. You need the original birth certificate, the CRIM negative-debt certification, the criminal record certificate, the ASUME compliance certification and the Hacienda negative-debt certification. Each comes from a different agency and several have their own guide here. If you lived outside Puerto Rico, add that jurisdiction’s criminal record certificate. The court warns the list is not closed: the judge can request additional documentation.
Step 3: File in duplicate the same day
Everything is filed at the court Clerk’s Office, and that same day you must send or deliver a copy of everything to the Prosecutor’s Office of your judicial region, and evidence it to the court. Form OAT 1896 has a space to record that delivery. Bring $78.00 in stamps.
Step 4: The prosecutor’s 10 days
The Prosecutor’s Office has 10 days from notification to object. If it does not object or does not answer, the case is submitted and the judge evaluates. They can rule on the documents — the usual course, and it is usually granted — or set a hearing. If there is an objection, the court notifies you and generally orders a hearing.
Step 5: If there is a hearing, bring two witnesses
On the hearing day you must appear with at least two people who know you and can attest that you are known by the name you propose. After the hearing, the judge issues the resolution granting or denying the change.
Step 6: What remains after winning
The resolution does not change your documents by itself. Return to the Clerk’s Office for a certified copy ($6.00 for the search and first page, $0.60 per additional page, plus $1.00 for certification). Take that certified copy to the Demographic Registry so it changes the name on your birth certificate. With the corrected certificate and the resolution, update your IDs at the Social Security Office, DTOP, the State Elections Commission and any other agency where you have a record under the old name.
Where to do it
At the Clerk’s Office of a Superior Courtroom of the Court of First Instance, with a same-day copy to the Prosecutor’s Office of your judicial region. The alternative is before a notary attorney, as a non-contentious matter.
How long it takes
What to do if something goes wrong
If what you want is for your child to carry their father’s surname, that is not this procedure: it is a filiation process, and the Judiciary says so expressly. There are guides here for paternity recognition and legitimation. If you need to correct the gender marker on a birth certificate, that is also a separate procedure with its own guide. If you cannot obtain one of the certifications because you have an outstanding debt, resolve it first: the certification must be negative. This guide states no processing time because the Judiciary does not publish one, and the document list is not closed: the judge can ask for more. PRFácil does not process name changes and gives no legal advice.
Common mistakes
- Confusing it with a surname change through filiation, which is a different process.
- Filing at the court and forgetting to deliver a copy to the Prosecutor’s Office the same day.
- Arriving with a single set of documents: two are needed, one for each destination.
- Requesting the certifications and finding at the counter that they show debt: they must be negative.
- Believing the resolution changes the birth certificate on its own: it must be taken to the Demographic Registry.
- Stopping there and not updating Social Security, DTOP and the CEE with the corrected certificate.
Frequently asked questions
Do I have to go to court?
Not necessarily. Act 282-1999, on non-contentious matters before a notary, expressly covers the change, substitution, addition, deletion, correction or modification of names or surnames in the Demographic Registry, so a notary attorney is the other route.
Will the change be denied?
The Judiciary states that when the judge rules on the documentation, it is usually granted. What the sworn statement certifies is that the change does not seek to evade civil or criminal liability; if denied, the resolution will tell you why.
What if I was born outside Puerto Rico?
This procedure is for people born in Puerto Rico and registered in the Demographic Registry. If you were born in another jurisdiction, the name change belongs to the civil registry where you were born.
What does it cost in total?
Filing is $78.00 in internal revenue stamps. Afterwards, the certified copy of the resolution costs $6.00 for the search and first page, $0.60 per additional page and $1.00 for the certification. To that you must add what each agency charges for its certifications, which this guide does not reproduce.
