A will is the instrument through which a person disposes of their property and expresses wishes to take effect after death, but its effectiveness depends on strict compliance with the formal requirements of the Brazilian Civil Code. Failing to meet them makes the provision absolutely void.

Legal nature and capacity to make a will

A will is a unilateral, strictly personal, gratuitous and revocable legal act. Through it, the testator disposes of the disposable portion of his or her estate and sets out instructions of a non-property nature. Brazilian civil law scholarship classifies the will as an act of last will, governed by Articles 1.857 to 1.990 of the Civil Code. Its validity requires strict observance of the form the law prescribes, because a will cannot be corrected once the succession opens.

To make a will, the person must be older than sixteen and fully capable of sound judgment at the time of the act, under Article 1.860 of the Civil Code. Incapacity that arises later, however, does not invalidate a will that was properly executed. Likewise, capacity acquired later does not validate a provision made by a person who lacked it. This rule reflects the principle of tempus regit actum (the law in force at the time of the act governs it) applied to dispositions mortis causa.

The case law of the Superior Tribunal de Justiça (Brazil’s Superior Court of Justice) has repeatedly held that an assessment of the testator’s mental soundness must look to the exact moment the will was executed. General allegations of senility or later illness are not enough to invalidate it. The burden of proof falls on the person challenging the will’s validity, who must present strong evidence that the testator lacked sound judgment at the moment of the declaration.

Ordinary forms under the Civil Code

Brazilian law recognizes three ordinary forms of will: public, closed, and private. The public will, governed by Article 1.864 of the Civil Code, is drawn up by a notary in the notary’s record book, based on the testator’s oral or written statement, and read aloud in the presence of two witnesses. Its main advantage is the legal certainty provided by the notary’s public faith and by the filing of the will at the notary’s office.

The closed will, governed by Articles 1.868 to 1.875 of the Civil Code, is written by the testator or by a person the testator trusts and delivered to the notary. The notary then prepares a certificate of approval in the presence of two witnesses. The document stays in the custody of the testator or of a third party the testator designates, and it is opened by a court after the testator’s death. This form keeps the contents completely confidential, which makes it attractive in sensitive situations.

The private will, provided for in Article 1.876 of the Civil Code, requires no notary. It must be handwritten or produced by mechanical means, then read before three witnesses who must sign it. After the testator’s death, it depends on court confirmation, with the witnesses examined, as Articles 1.877 and 1.878 of the same Code require. Its formal simplicity comes at the cost of greater evidentiary vulnerability, especially when the witnesses are hard to find.

A will may be void because of a defect of form, the testator’s incapacity, an unlawful object, or fraud.

Special forms and requirements for effectiveness

Besides the ordinary forms, the Civil Code provides for three special forms that apply in exceptional circumstances: maritime, aeronautical and military wills, governed by Articles 1.888 to 1.896. These wills lapse ninety days after the testator disembarks on dry land or the military campaign ends, unless the testator dies in the meantime, as Article 1.891 provides. The time limit reflects the exceptional circumstances that justify setting aside the ordinary formalities.

The effectiveness of any will also depends on respect for the forced share (legítima) of the compulsory heirs, which is fifty percent of the testator’s net estate under Article 1.846 of the Civil Code. Provisions that exceed the disposable portion are proportionally reduced through a reduction action, without invalidating the entire will. The compulsory heirs are descendants, ascendants and the spouse, as listed in Article 1.845.

A will may be void because of a defect of form, the testator’s incapacity, an unlawful object, or fraud. A will that is merely voidable, by contrast, covers cases of mistake, fraud or duress, with a four-year limitation period counted from when the defect becomes known, in light of the sole paragraph of Article 1.909. The distinction between a void and a voidable will has significant procedural consequences, especially for standing to sue, deadlines, and the possibility of cure.

Frequently Asked Questions

Can a public will be made while the testator is in the hospital?

Yes. The notary may go to the hospital to draw up a public will, as long as the testator is conscious and able to express his or her wishes freely and with full understanding. Two witnesses are indispensable. They cannot be heirs, legatees or close relatives who benefit from the will, or the provision in their favor is invalid, as Article 1.801 of the Civil Code prohibits.

What is the practical difference between a closed will and a private will?

A closed will involves a notary at the approval stage, which gives greater protection against claims of forgery or defective consent. A private will does not require a notary, but it requires three witnesses present for the reading and signing, plus court confirmation after death. Choosing between them means weighing the notary’s cost, the need for confidentiality, and how strong the testator wants the evidence to be.

Can I revoke a will I already made?

Revocability is an essential feature of a will. Revocation may be total or partial, and it may be made through a new will or through an express declaration in a later public instrument. Revocation by implication occurs when later provisions are incompatible with earlier ones, in which case the more recent ones prevail, under Article 1.969 of the Civil Code. Clauses that try to make a will irrevocable are treated as unwritten because they go against the nature of the instrument.
