Short answer. Generally no. RA 9048 lets a civil registrar correct clerical or typographical errors and change a first name or nickname without a court. A true change of surname is not on that short list, so it still requires a judicial order except where a separate special law provides otherwise.

What the administrative shortcut actually covers
RA 9048 created a way to fix certain civil registry entries without a court case, but it is narrower than many hope. The general rule it restates is that No entry in a civil register shall be changed or corrected without a judicial order, except for clerical or typographical errors and change of first name or nickname. Two things fall inside the exception: harmless clerical or typographical mistakes, and a change of first name or nickname. Everything else in your civil record stays under the default — it needs a judicial order.
Why a surname is treated differently
The law guards surnames more carefully than first names because a surname signals filiation, family and legal relationships — who your parents are, which family you belong to, and rights that flow from that. Changing it can affect inheritance, legitimacy questions and the interests of other people who share or rely on the name. That is why the shortcut deliberately leaves surnames out. A misspelled surname that is plainly a typing error can be corrected administratively as a clerical error, but actually substituting one surname for another is a change of status-laden information, and the law keeps that decision with a court.
The narrow exceptions worth knowing
There are a few situations where a surname question is handled without an ordinary court petition, but they come from separate, specific statutes rather than from this general shortcut — for example, the special law allowing an acknowledged illegitimate child to use the father's surname. Those are targeted rules for particular circumstances, not a general right to swap surnames at the registrar's counter. If your situation happens to fit one of them, the path may be administrative; if it does not, you are back to the default rule that a genuine surname change needs a judicial order.
Figuring out which path is yours
Before assuming you must litigate — or that you can avoid it — pin down what you are really asking for. Is the surname simply misspelled in the record, is it a first name or nickname you want changed, or do you want to adopt a different surname altogether? The first two can often be done administratively; the last generally cannot. Because the categories carry different procedures, evidence and costs, it is worth confirming which one your case falls into before filing anything. A lawyer or the local civil registrar can tell you whether your request is a clerical fix, a covered name change, or a matter for the courts.
A later law expanded this process
This administrative correction process comes from Republic Act No. 9048. In 2012, Republic Act No. 10172 amended Republic Act No. 9048 to add two more errors — a wrong day or month of birth, and a wrong entry of sex — to this same civil-registrar route, without a court order. The procedure and documents above still apply; Republic Act No. 10172 widened what can be fixed, not how it works.
