Short answer. At 18 you reach the age of majority — emancipation ends your parents' authority over your person and property, and you become qualified and responsible for all acts of civil life: you may contract, sue, take a job and manage your own property without their consent, subject only to exceptions fixed by special laws.

Eighteen is now the age of majority
Until Republic Act No. 6809 took effect, the age of majority in the Philippines was twenty-one. That Act lowered it to eighteen, so on your eighteenth birthday you are emancipated automatically — no court order, no ceremony. Emancipation means parental authority over both your person and your property ends. From that day you can enter contracts, file or defend a lawsuit in your own name, accept employment, open your own accounts and deal with your own property without a parent or guardian signing for you or consenting. In short, the law now treats your acts as fully your own rather than as a minor's acts needing an adult behind them.
The marriage exception that survives
Turning eighteen does not remove every limit. The law expressly keeps one: Contracting marriage shall require parental consent until the age of twenty-one. So between eighteen and twenty-one you may marry, but you still need your parents' consent to do so; a marriage without it can be annulled. Reaching majority also does not by itself qualify you for things the law ties to a higher age or to separate conditions — buying alcohol or tobacco, holding certain offices, or acts that special laws reserve for older persons. Emancipation opens the general field of civil life; particular activities can still carry their own age rules that eighteen alone does not satisfy.
Responsibility cuts both ways
Being qualified and responsible for all acts of civil life is not only a set of freedoms — it is exposure. Before, a minor's contract could be disaffirmed and a parent generally answered for the child's civil wrongs. After emancipation you are bound by the contracts you sign and answerable for your own obligations and negligence; a creditor or an injured person now looks to you, not to your parents. The law does add that nothing in it relieves parents and guardians of the duties they still owe for children and wards below twenty-one, so a narrow band of shared responsibility survives — but the general rule is that at eighteen the consequences of your choices are yours to carry.
What emancipation does not give you
Emancipation is about legal capacity, not maturity or money, and it does not cut family ties. Your parents' duty to support you, and yours to them, rests on need and relationship rather than on age, so support can continue past eighteen — for instance while you are still studying. Emancipation also does not hand you property that is not yet yours; an inheritance or a parent's assets stay theirs until the law or a document transfers them. It does not erase debts you already owe or shorten periods the law counts from majority. If a contract, a marriage, or a support question turns on your new status, confirm the details with counsel before you act on them.
