Civil capacity is one of the foundations of Brazilian civil law because it determines who may personally carry out the acts of civil life. Understanding the difference between absolute and relative capacity is essential to protecting rights and ensuring that legal transactions are valid.

The 2002 Civil Code sets out clear rules about who has full ability to perform legal acts and who needs representation or assistance. These rules changed significantly with the Statute of Persons with Disabilities (Law 13.146/2015), which reshaped the treatment of incapacity in Brazilian law.

What Is Civil Capacity?

Civil capacity is the ability, recognized by the legal system, to acquire rights and take on obligations. There are two types: capacity to hold rights (capacidade de direito, also called capacity of enjoyment) and capacity to act (capacidade de fato, also called capacity of exercise).

Every human being has capacity to hold rights from the moment of live birth, under Article 1 of the Civil Code. Capacity to act, on the other hand, is the ability to personally carry out the acts of civil life, and this is precisely where legal limitations arise.

A person who has both types of capacity has full civil capacity. When there is a restriction on capacity to act, the person is legally incapable, and the incapacity may be absolute or relative.

Absolute Incapacity After the Statute of Persons with Disabilities

Before Law 13.146/2015, Article 3 of the Civil Code listed several situations of absolute incapacity, including people with mental illness or mental disability. Today, after the reform introduced by the Statute, the only people who are absolutely incapable are those under 16.

This change was a major step forward in protecting the rights of people with disabilities, recognizing their autonomy and dignity. Persons who are absolutely incapable must be represented by their parents, guardians, or other legal representatives in all acts of civil life.

Acts performed by absolutely incapable persons without proper representation are void by operation of law and produce no valid legal effect.

The voidness of acts performed without representation is provided for in Article 166, item I, of the Civil Code. This means that a transaction entered into by a person under 16 without a legal representative may be declared void at any time and cannot be ratified.

Relative Incapacity and Its Categories

Persons who are relatively incapable, as listed in Article 4 of the Civil Code, may perform acts of civil life as long as they are assisted by their legal representatives. They are:

• Persons over 16 and under 18
• Habitual drunkards and drug addicts
• Those who, for a temporary or permanent reason, cannot express their will
• Spendthrifts (pródigos)

Acts performed by relatively incapable persons without proper assistance are voidable, under Article 171, item I, of the Civil Code. Unlike absolute voidness, a voidable act can be cured by the parties’ ratification or by the expiration of the forfeiture period (prazo decadencial).

Practical Differences Between Absolute and Relative Incapacity

Understanding the differences between these two categories is fundamental in legal practice. The main distinguishing points are summarized below:

Emancipation and the End of Incapacity

Civil incapacity ends when a person reaches the age of majority (18) or through emancipation, which is provided for in Article 5, sole paragraph, of the Civil Code. Let’s look at the main forms of emancipation:

Voluntary emancipation occurs when the parents grant it by public instrument to a minor who has turned 16. Judicial emancipation is granted by a judge, after hearing the guardian, when the minor is also 16 years old. There is also legal emancipation, which happens automatically in situations such as marriage, holding an effective public job, graduating from a college or university program, and running a civil or commercial business that gives the minor financial independence.

Once emancipated, a minor acquires full civil capacity and may perform all acts of civil life independently. Note, however, that emancipation is irrevocable.

The Role of Curatela and Supported Decision-Making

For adults who fall within the categories of relative incapacity, Brazilian law provides two protective mechanisms: curatela (a court-ordered guardianship for adults) and supported decision-making (tomada de decisão apoiada).

Curatela is an exceptional measure, proportional to the needs of the person under it, and it should last as short a time as possible. The Statute of Persons with Disabilities reinforced that curatela affects only acts of a property and contractual nature, preserving the person’s autonomy over personal decisions such as marriage, work, and voting.

Supported decision-making, provided for in Article 1.783-A of the Civil Code, is a mechanism through which a person with a disability chooses at least two trusted people to help them make decisions about acts of civil life. It preserves the person’s autonomy and is a less restrictive alternative to curatela.

Legal Consequences of Acts Performed by Incapable Persons

The legal effects vary according to the degree of incapacity. When a person is absolutely incapable, an act performed without representation is void (Article 166, I, of the CC). A judge may recognize this on his or her own initiative, and no limitations period applies.

When a person is relatively incapable, an act performed without assistance is voidable (Article 171, I, of the CC). The interested party must request that it be annulled, and the request is subject to a four-year forfeiture period, counted as provided in Article 178 of the Civil Code.

It is worth noting that there are important exceptions. A minor between 16 and 18 cannot invoke his or her age to escape an obligation if the minor intentionally concealed it, under Article 180 of the Civil Code. In addition, legal personality and its temporal milestones directly affect the analysis of civil capacity.

For situations involving incapacity and rights before the public administration, it is helpful to understand the principles of administrative legality that govern these relationships.

Frequently Asked Questions

Does the Civil Code consider a person with a disability to be incapable?

No. Since the Statute of Persons with Disabilities (Law 13.146/2015) took effect, disability alone is not a cause of civil incapacity. A person with a disability has legal capacity on an equal basis with others and may need only support to exercise that capacity, such as supported decision-making.

What is the difference between representation and assistance?

In representation, the legal representative performs the legal act on behalf of the incapable person, replacing that person’s will. In assistance, the relatively incapable person performs the act personally, but with the presence and consent of the assistant. Representation applies to the absolutely incapable (those under 16), while assistance is for the relatively incapable.

Can a child under 16 have a bank account?

Yes, but the account must be opened and operated by the child’s legal representative (a parent or guardian). A child under 16 cannot enter into a banking contract or carry out financial transactions alone, because these are acts of civil life that require capacity to act, which an absolutely incapable person does not have.
