Short answer. Yes. The second ground in Section 4 exists for exactly this: the new first name or nickname has been habitually and continuously used by the petitioner, and he has been publicly known by it in the community. Both halves have to be shown, and the second is about other people.

Two elements, joined by 'and'

The new first name or nickname has been habitually and continuously used by the petitioner and he has been publicly known by that by that first name or nickname in the community. The first element is your own conduct: habitual and continuous use, which excludes a name adopted recently or used only in some settings. The second element is other people's knowledge of you, in the community, publicly. They are cumulative. Someone who has used a name privately for decades but whose records all show the registered one satisfies the first and fails the second.

The proof has to come from outside your household

Because the second element is about public recognition, the useful evidence is documentary and third-party: school records, employment and payroll files, church or membership records, barangay and other local government records, professional or licensing records, and anything else generated by an institution that wrote down the name it knew you by. The longer the span those documents cover, the better they answer the words habitually and continuously. Affidavits from neighbours and colleagues supplement that record; they are weakest when they are the only thing offered.

This is a change, not a correction

It is worth being clear about which track you are on, because the two are handled differently. If the registered entry is a misspelling of the name you actually have, that is a clerical or typographical error and a simpler petition. If the registered entry is a different name from the one you use, this is a change of first name — and the change reaches the first name or nickname only. The middle and last names are not touched by it. Petitions that mix the two up are a common reason for a return at the counter.

The extra steps for a name change

Section 5 attaches two requirements to a change of first name that a clerical correction does not carry: the petition must be published at least once a week for two consecutive weeks in a newspaper of general circulation, and the petitioner must submit a certification from the appropriate law enforcement agencies that he has no pending case or criminal record. Both make sense once you see what the change does — it alters the name under which third parties can find you. Budget for the publication, and note that Section 3 permits these petitions only once.
