At what age does a Filipino legally become an adult?

One sentence changed the age

Emancipation takes place by the attainment of majority. Unless otherwise provided, majority commences at the age of eighteen years. Before this amendment majority came at twenty-one, and emancipation could also be brought about in other ways. The amendment collapsed the question: reaching eighteen is now the event, and it happens automatically, without any petition, court order, parental act or registration. Nobody grants it and nobody can withhold it. That simplicity is why the age of majority is one of the few questions in Philippine family law with a clean one-line answer.

What turning eighteen actually does

Emancipation shall terminate parental authority over the person and property of the child who shall then be qualified and responsible for all acts of civil life, save the exceptions established by existing laws in special cases. Both halves matter. Parental authority ends — over the person and over the property, so a parent no longer administers what the young adult owns. And capacity arrives with responsibility attached: an eighteen-year-old is answerable for what he does and what he signs, which is the part families tend to notice later than the freedom.

The phrase that keeps the answer from being universal

Unless otherwise provided is not throat-clearing. Particular laws set their own ages for their own purposes, and majority under this provision does not override them. So the useful form of the question is rarely am I an adult; it is may I do this specific thing at this age, and that is answered by the statute governing that thing. The same caution applies in the other direction — reaching eighteen does not automatically qualify a person for everything the law reserves to adults, nor strip away every protection the law gives to the young.

Two things stayed at twenty-one

The amending law expressly kept parental consent as a requirement for contracting marriage until the age of twenty-one, so an eighteen-year-old is an adult for contracts but not for marrying freely. And it preserved the duty and responsibility of parents and guardians for children and wards below twenty-one years of age under the Civil Code provision on vicarious liability, so parents remain exposed for damage caused by a young adult still living in their company. The band between eighteen and twenty-one is therefore not simply adulthood; it is adulthood with two named residues.
