Short answer. Yes. A misspelled middle name is a clerical or typographical error, which the law lets the local civil registrar correct without going to court. Republic Act No. 9048, later expanded by RA 10172, allows these harmless, obvious mistakes to be fixed administratively, so you file with the civil registrar rather than a judge.
What the law says
refers to a mistake committed in the performance of clerical work in writing, copying, transcribing or typing an entry in the civil register that is harmless and innocuous, such as misspelled name or misspelled place of birth or the like, which is visible to the eyes or obvious to the understanding

A misspelling is a clerical error
Republic Act No. 9048 defines the kind of mistake that can be fixed without a court. A clerical or typographical error refers to a mistake committed in the performance of clerical work in writing, copying, transcribing or typing an entry in the civil register that is harmless and innocuous, such as misspelled name or misspelled place of birth or the like, which is visible to the eyes or obvious to the understanding. A misspelled middle name is the textbook example. It is the sort of slip that anyone can see is a typing error, correctable by checking against your other records, rather than a genuine dispute about who you are.
Corrected without a court order
Because the misspelling is clerical, you do not need a judicial petition. RA 9048 empowers the city or municipal civil registrar — or the consul general, if the record is kept abroad — to correct such errors administratively. You bring the request to the registrar who holds your record, supported by documents that show the correct spelling, and the registrar acts on it under the Act. This administrative route replaced the slow and costly court process that used to be required for even the smallest typographical fix, which is precisely why an obvious misspelling can now be handled at the registry.
What administrative correction cannot reach
The streamlined route has firm boundaries. The Act itself provides that no correction must involve the change of nationality, age, status or sex of the petitioner — those are substantial matters that still need a court. The scope was, however, later widened. Republic Act No. 10172, passed in 2012, amended RA 9048 to also allow the administrative correction of the day and month of birth and of a clerical error in the sex or gender entry — items the original text excluded. So while a misspelled middle name is plainly within the registrar's power, changes that alter identity in a deeper way remain outside it, subject to what RA 10172 added.
Practical limits
For the correction to qualify, the error should be obvious and provable from your existing documents — the point is that it can be fixed by reference to other records, not by re-litigating the facts of your birth. If what you are really seeking would change your status, your nationality, or the substance of your identity, that is not a mere clerical fix and the administrative route will not carry it. And if the registrar declines the correction, a judicial remedy is still open to you. For a simple misspelled middle name backed by consistent records, though, the registry is normally the right and sufficient door to knock on.
