The legal term inter vivos, of Latin origin, designates legal acts whose effects are produced during the lifetime of those who perform them. Primarily inserted in Civil and Tax Law, the institute is contrasted with causa mortis succession, serving as a fundamental criterion for the incidence of taxes and the validity of legal transactions involving the disposal of assets.
Concept and Foundation
The expression inter vivos (between the living) qualifies legal acts that operate their effects immediately, or within a pre-established term/condition, while the subjects of the legal relationship still possess full civil capacity and biological existence. Unlike mortis causa acts, which have the event of death as their triggering factor, the inter vivos institute is based on private autonomy and the free disposal of assets during one's lifetime.
The legal nature of the institute lies in immediate transactional effectiveness. In Succession Law and the Law of Obligations, the distinction is essential for the application of the saisine principle and for the delimitation of tax jurisdiction. Inter vivos transmission is the foundation of donations, purchase and sale contracts, and exchanges, differing from succession transmission which occurs only with the opening of the succession.
Historical Origin and Evolution
The concept derives from Roman Law, which already operated the distinction between acts of disposal during life and acts of last will (wills). Historical evolution consolidated the need to distinguish assets that circulate by force of private autonomy from those that are transmitted by operation of law due to death. In the Brazilian legal system, the 1916 Civil Code and, subsequently, the 2002 Civil Code (Law No. 10.406/2002), maintained the structure that the transmission of real estate, for example, requires the registration of the inter vivos translative title in the Real Estate Registry (art. 1.245, CC).
Legal Provision and Practical Application
The application of the institute finds direct support in the 1988 Federal Constitution, specifically in art. 156, II, which grants Municipalities the competence to institute taxes on the "inter vivos transmission, by any means, for a valuable consideration, of real estate".
Within the scope of the Civil Code, the following stand out:
- Art. 538: Defines donation as a contract in which a person transfers assets or advantages from their estate to that of another, a typically inter vivos act.
- Art. 1.245: Establishes that the transfer of property between the living occurs through the registration of the translative title.
- Art. 2.018: Allows the partition of assets between the living, by an act between the living or a last will provision, provided it does not prejudice the legitimate share of necessary heirs.
Current Jurisprudence and Court Understanding
The Supreme Federal Court (STF) has been examining the interpretation of the ITBI (Tax on the Transfer of Real Estate) inter vivos. In the judgment of ARE 1294969 (Theme 1113), the Court established a general repercussion thesis stating that the triggering factor for the tax is the effective transfer of real estate property, through registration in the competent notary office, excluding incidence on a mere promise of purchase and sale.
Furthermore, within the scope of Succession Law, the Superior Court of Justice (STJ) constantly reinforces that inter vivos donations that exceed the portion the donor could dispose of in a will (inofficious donation) are void to the extent that they exceed the limit of the legitimate share, according to art. 549 of the Civil Code, ensuring protection for necessary heirs.
Related Principles and Doctrinal Divergences
The principle of private autonomy is the pillar that supports inter vivos transactions. However, there is doctrinal divergence regarding the limits of inter vivos donation against the legitimate share of heirs. While part of the doctrine defends absolute freedom of disposal, the majority current, aligned with the protection of the family, understands that inter vivos donation cannot be used as a means of fraud against succession (inofficious donation).
Another point of contemporary debate refers to the transmission of digital rights and crypto-assets. It is discussed whether the transfer of private keys for digital assets constitutes a typical inter vivos act or if, due to the nature of the asset, it should suffer restrictions similar to succession ones, given the difficulty of control by the tax authorities.
Contemporary Relevance and Impacts
The relevance of the term inter vivos is strategic in succession planning (family holding). The anticipation of the legitimate share via inter vivos donation with reservation of usufruct is a legal instrument widely used to avoid judicial inventory, reduce tax costs, and ensure business succession. The legal certainty provided by the registration of the inter vivos act is what maintains the stability of the real estate market and confidence in contractual relations in Brazil.
