Can an eighteen-year-old sign a contract without a parent joining in?

Capacity arrives whole

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. Parental authority over property ends alongside authority over the person, which is the half people forget. A parent no longer administers what the young adult owns and no longer needs to concur in dealings with it. Emancipation itself is automatic — Emancipation takes place by the attainment of majority. Unless otherwise provided, majority commences at the age of eighteen years.

Qualified and responsible, in that order

The provision grants capacity and liability in the same breath, and the second word is the one worth dwelling on. A contract signed at eighteen binds. There is no residual power in a parent to disown it, no requirement of ratification, and no general right to walk away on the ground of youth. The protections that surround a minor's contracts — the ones that let an agreement be avoided because the party was under age — stop at the birthday. Anyone dealing with an eighteen-year-old, and the eighteen-year-old himself, should proceed on that footing.

The exceptions are found in other statutes

Save the exceptions established by existing laws in special cases is a pointer, not a hedge. Particular laws impose their own age or consent requirements for particular transactions, and this provision does not sweep them away. So a flat yes is right as a general answer and wrong as a universal one: where a specific statute governs the specific transaction, that statute decides. The practical question is never whether an eighteen-year-old can contract in the abstract, but whether the particular dealing is one the law has singled out.

What did not change at eighteen

The same section keeps two things at twenty-one, and neither touches contractual capacity. Contracting marriage still requires parental consent until the age of twenty-one. And 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, is expressly preserved — so parents may still answer for damage a young adult causes while living in their company. That liability arises from wrongdoing, not from agreements, and it does not give a parent any say over what his adult child signs.
