Short answer. Generally no. Article 376 of the Civil Code provides that no person can change a name or surname without judicial authority. A change of name requires a court proceeding — a person cannot simply adopt a new name or surname, even one used consistently in daily life, without that court-issued authorization.

The judicial requirement under Article 376
Article 376 of the Civil Code states plainly: "No person can change his name or surname without judicial authority." This is a categorical rule. Changing a first name or a family name — or both — requires a court order. The requirement reflects the civil registration system's reliance on stable, verifiable identities. A person's legal name is recorded in civil registry documents from birth, and those records form the backbone of all official documentation throughout life. Altering them without court oversight would undermine the integrity of that system.
What the requirement means in practice
A petition for change of name must be filed in the Regional Trial Court of the province or city where the petitioner was born or resides. The court evaluates whether there is a proper and reasonable cause for the change — examples recognized in practice include names that are ridiculous or contemptible, names that cause confusion with another, or first names that have become habitually used to the point that the registered name is practically unknown. The court process involves publication of the petition, an opportunity for any person to object, and a hearing before the court issues its order.
Administrative corrections are different from name changes
Not every modification to a civil registry entry requires a court case. Republic Act No. 9048 and Republic Act No. 10172 allow the civil registrar to correct clerical or typographical errors in civil registry documents — such as misspellings, or errors in birth month or sex — through an administrative process rather than a court petition. However, these laws apply to corrections of obvious errors, not to a change of first name or surname as a matter of preference or for other substantive reasons. The distinction matters: changing a name is governed by Article 376, while correcting a clerical error is a different, simpler procedure.
Using a different name without changing it
Many Filipinos go by a nickname or an entirely different name in everyday life without ever legally changing their registered name. This is not in itself illegal, but it has limits. Official documents — government IDs, passports, employment records, property titles, bank accounts — must reflect the legal name as registered. A name habitually used but never legally adopted through a court order remains informally a nickname, not a legal change. For purposes that require official documentation, the registered name controls, and any discrepancy between the name used and the registered name can create complications in legal, contractual, and administrative contexts.
