General Rule Under Republic Act No. 6809
Capacity to act is the power to do acts with legal effect through one's own will. Juridical capacity makes a person a subject of rights and obligations; capacity to act enables that person to acquire, exercise, modify, or extinguish rights by personal acts.
Republic Act No. 6809 lowered the age of majority from twenty-one to eighteen years. As a general civil law rule, a natural person acquires full capacity to act upon attaining eighteen years of age, unless a special law imposes a different age, qualification, consent requirement, disability, or restriction for a particular act.
The statute also made emancipation take place by attainment of majority. In present civil law usage, emancipation is no longer a separate status produced by parental concession or by the mere fact of marriage before majority. Emancipation and majority now coincide at eighteen.
The rule is one of legal capacity, not merely social independence. A person who has reached eighteen is generally qualified and responsible for acts of civil life, while a person below eighteen remains subject to the rules on minority and representation except where a special law supplies a limited capacity.
Acquisition of Capacity to Act
Capacity to act is acquired by operation of law. It is not granted by parents, guardians, schools, employers, or private agreements. Parties may recognize or deal with a person as an adult, but private treatment cannot accelerate majority or remove a statutory incapacity.
The controlling age is the age at the time the juridical act is performed. A contract, waiver, conveyance, compromise, or other act made while the person is still below eighteen is judged under the law on minority, even if the person later reaches majority. Subsequent majority may permit ratification when the act is merely voidable, but it does not retroactively create original capacity at the time of the act.
Once majority is attained, the incapacity arising from minority ceases without need of a court order. No judicial declaration of majority is required for the person to enter contracts, manage property, sue or be sued in his own name, or perform other civil acts, subject to formal requirements and special restrictions imposed by law.
Legal Effects of Majority at Eighteen
Attaining eighteen produces a general change in civil status. The person is no longer treated as an unemancipated minor for ordinary civil transactions and becomes personally answerable for the legal consequences of acts validly performed.
- Contractual capacity. The person may give consent to contracts, bind himself by obligations, and enforce contractual rights without parental or guardian representation.
- Property administration. The person may administer, enjoy, encumber, alienate, or otherwise deal with his property, subject to the substantive and formal rules governing the particular transaction.
- Litigation capacity. The person may ordinarily sue and be sued in his own name, without appearing through a parent, guardian, or guardian ad litem solely by reason of age.
- Personal civil acts. The person may perform acts affecting civil status, obligations, succession, agency, partnerships, associations, and other legal relations when no special incapacity applies.
- Responsibility for civil acts. The person generally bears direct responsibility for obligations, damages, admissions, ratifications, waivers, and other legal consequences validly attached to his acts.
- Testamentary capacity by age. A person who has reached eighteen satisfies the age requirement for making a will, although soundness of mind and testamentary formalities remain indispensable.
Majority supplies general capacity only. It does not dispense with notarization, public instrument requirements, board or corporate authority, marital consent where required, court approval where the law demands it, licensing rules, or the substantive requisites of the juridical act.
Emancipation and Parental Authority
Emancipation terminates parental authority over the person and property of the child. Upon majority, the former minor no longer needs parental authority as the legal basis for ordinary representation, custody decisions, or property administration.
The termination of parental authority does not erase family relationships, support obligations, succession rights, moral duties, or liabilities imposed by special rules. The parent-child relationship remains, but the legal power of the parent to represent and control the child by reason of minority ends.
Republic Act No. 6809 expressly preserves the civil responsibility of parents and guardians for children and wards below twenty-one years of age in the setting of quasi-delict. Thus, a person who is eighteen, nineteen, or twenty may already have general capacity to act, yet the parent or guardian may still be answerable under the Civil Code rule on vicarious liability if its requisites are present.
This preserved liability is not a continuation of full parental authority. It is a statutory allocation of responsibility for damage caused by persons below twenty-one who remain within the legally relevant family or guardianship situation contemplated by the rule, subject to the defenses allowed by law.
Contracts Before and After Eighteen
Before eighteen, the general rule is incapacity to give effective contractual consent. Contracts entered into by unemancipated minors are ordinarily voidable, not void, when all other essential requisites are present. The contract exists and may produce effects until annulled, but it is vulnerable because consent was given by one incapable of giving it.
After reaching eighteen, the former minor may ratify a voidable contract entered into during minority. Ratification may be express or implied, and it cleanses the contract from the defect of minority from the time of its constitution. The right to annul based on minority is lost when valid ratification occurs.
The other party who contracted with the minor generally cannot use the minor's incapacity as a weapon to escape the agreement. The protection belongs principally to the incapacitated party, because the law treats minority as a shield against improvident or unequal dealings.
If annulment is allowed, restitution follows the rules for voidable contracts. A minor is not ordinarily bound to return more than what he was benefited by the thing or price received, because the law does not allow the protective policy of minority to be defeated by ordinary restitution rules.
Transactions for necessaries, statutory benefits, employment-related matters, banking, education, insurance, and other regulated dealings may be governed by special rules. These limited capacities do not change the general rule that full civil capacity is acquired at eighteen.
Marriage as a Special Case
Republic Act No. 6809 lowered majority to eighteen but retained a special rule for marriage. A person who is eighteen or over but below twenty-one generally needs parental consent to contract marriage. The person is already of majority age for ordinary civil acts, yet marriage remains subject to this additional family law requirement.
Lack of the required parental consent does not mean the person is a minor in all respects. It means the marriage is affected by the specific consequence provided by family law. The special consent requirement operates only within its own field and does not reduce the person's general civil capacity for unrelated acts.
Persons below eighteen cannot rely on emancipation to validate marriage, because emancipation now takes place by majority and child marriage is separately prohibited by law. The modern rule separates the age of majority from any obsolete idea that marriage before majority can produce civil emancipation.
Relationship With Juridical Capacity
Juridical capacity and capacity to act must be kept distinct. Juridical capacity is the fitness to be the subject of legal relations and is inherent in every natural person. Capacity to act is the power to create legal effects by one's own acts and may be restricted by law.
A child may own property, inherit, receive donations, be supported, or be protected by law even before having full capacity to act. In those situations, the law recognizes juridical capacity but supplies representation, parental authority, guardianship, or court supervision to compensate for the lack of full personal capacity.
Majority does not create personhood. It changes the mode by which rights are exercised. Before eighteen, many rights are enjoyed through legal representatives; at eighteen, the person generally exercises those rights personally.
Continuing Limitations After Majority
Attaining eighteen removes incapacity based on minority, but it does not remove other limitations established by law. Capacity to act may still be modified by mental condition, penalty, family relations, alienage, absence, insolvency, trusteeship, and other circumstances that the law treats as relevant to the particular act.
| Circumstance | Effect on Capacity |
|---|---|
| Mental incapacity | Insanity, dementia, or comparable incapacity may defeat valid consent even if the person is over eighteen. |
| Civil interdiction or penalty | A criminal penalty may restrict the exercise of civil rights, property administration, or family rights as provided by law. |
| Family relations | Marriage, parental authority, guardianship, and support relations may impose special consents, prohibitions, or duties. |
| Alienage | Citizenship restrictions may limit ownership, business participation, public rights, or certain regulated transactions. |
| Insolvency or trusteeship | Legal control over property may shift to a trustee, assignee, receiver, or court-supervised process. |
| Special statutory age | A law may require an age higher or lower than eighteen for a specific license, office, consent, privilege, or regulated act. |
Because capacity is determined by law, the inquiry is always act-specific. The fact that a person is eighteen answers the question of minority, but it does not automatically answer every question of legal qualification.
Comparison of the Main Effects
| Subject | Rule After Republic Act No. 6809 | Legal Consequence |
|---|---|---|
| Age of majority | Majority generally begins at eighteen. | Capacity to act based on age is generally acquired at eighteen. |
| Emancipation | Emancipation takes place by attainment of majority. | There is no need for parental concession or a separate act to emancipate the child. |
| Parental authority | Parental authority over the person and property of the child ends upon emancipation. | The eighteen-year-old ordinarily acts without parental representation. |
| Marriage | Parental consent remains required for marriage until twenty-one. | The rule is a special family law qualification, not a denial of general majority. |
| Quasi-delict responsibility | Parental or guardian responsibility for children or wards below twenty-one is preserved where the law so provides. | A person may be of majority age while a parent or guardian remains exposed to statutory vicarious liability. |
Effect on Acts Involving Property and Obligations
At eighteen, a person may generally bind his property by contract, mortgage, sale, lease, loan, guaranty, compromise, settlement, or waiver. The validity of the act still depends on consent, object, cause, form, authority, and any special prohibition applicable to the transaction.
For property acquired during minority, the transition to majority shifts control from representative management to personal administration. The property is not newly acquired by reason of majority; what is acquired is the ability to deal with it personally.
If a guardian, parent, administrator, or trustee has been lawfully managing property, majority may require accounting, turnover, or termination of the representative authority, subject to the governing order, bond, settlement, or special proceeding. The former minor's new capacity does not excuse prior representatives from accountability for acts done during their administration.
For obligations incurred after eighteen, the person cannot avoid liability by invoking the former status of minority. Age-based incapacity ceases at majority, and the ordinary rules on obligations, damages, interest, prescription, default, and remedies apply.
Effect on Representation and Litigation
A minor generally acts in court through parents, a guardian, or a guardian ad litem because procedural acts may prejudice substantive rights. Once the person reaches eighteen, the age-based need for representative standing ends, and the person may control the action, settle claims, engage counsel, receive notices, and be bound by procedural choices.
If a case began while the party was a minor, reaching majority may require substitution, appearance in one's own name, or recognition by the court that representation is no longer necessary. The substantive claim does not disappear; only the procedural basis for representation changes.
Compromises, waivers, admissions, and settlements made after majority are generally assessed as acts of a person with capacity. They may still be attacked for fraud, mistake, violence, intimidation, undue influence, lack of authority, or violation of law, but not merely because the person used to be a minor.
Doctrinal Synthesis
Republic Act No. 6809 makes eighteen the ordinary civil threshold between minority and majority. At that point, the law generally treats the person as capable of producing legal consequences by personal acts and as responsible for those consequences.
The acquisition of capacity to act is automatic, general, and prospective. It is automatic because no further act is required; general because it applies to civil acts as a class; and prospective because acts done before majority remain governed by the law applicable when they were made.
The rule is also qualified. Majority does not override special statutory ages, parental consent for marriage below twenty-one, preserved vicarious liability for children and wards below twenty-one, mental incapacity, penalties, family law restrictions, citizenship limitations, or court-supervised property regimes.
The practical civil law formula is therefore simple: juridical capacity exists from the beginning of personality, but capacity to act is generally acquired at eighteen under Republic Act No. 6809, subject to specific limitations that the law attaches to the person, the act, or the property involved.
