The prenuptial agreement is no longer an instrument associated only with great fortunes and begins to occupy space in broader conversations about autonomy, asset organization and legal security within marriage.

Formalized before the civil celebration, it serves to define the property regime and record property rules that will guide the couple’s life throughout the union. In practice, it is a document that anticipates decisions that many people only realize they needed to take when the conflict has already begun.

Graziela Jurça Fanti, a lawyer specializing in women and LGBTQIAPN+ people, notes that the increase in interest in the pact accompanies a relevant change in women’s economic lives. Today, more Brazilian women enter marriage with their own income, assets already established, participation in business, expectation of inheritance or direct responsibility for maintaining the house. This new context means that the discussion about the property regime stops being a bureaucratic detail and becomes part of the construction of common life.

Data reveals change in behavior

The movement appears in the numbers. A survey carried out by the Brazilian Institute of Family Law (IBDFAM), based on data from the Colégio Notarial do Brasil, showed that the country registered 70,289 prenuptial agreements in 2025, a growth of 82% compared to the previous five years.

At the same time, the 2022 Census from the Brazilian Institute of Geography and Statistics (IBGE) showed that 49.1% of Brazilian domestic units already had women as heads. When these data are read together, they help to explain why the pact came to be seen with less resistance and more pragmatism.

Marriage also involves legal rules

For a long time, talking about assets before marriage was treated as a sign of coldness, distrust or a prediction of relationship failure. This reading still exists, but it loses strength as marriage is no longer understood solely from an affective perspective and is also recognized as a union with civil, succession and economic effects. Whoever gets married assumes a series of legal implications, and ignoring them does not make these consequences any less. It just pushes the problem into the future.

According to Graziela Jurça Fanti, the greatest virtue of the prenuptial agreement is in reducing gray areas. “It allows the couple to clearly choose the property regime and record, within the limits of the law, which patrimonial logic you intend to adopt. This prevents important decisions from being loose or dependent on later interpretations, especially when there is property prior to marriage, business activity, children from other relationships or expectations of succession”, he states.

When organizing your assets makes a difference

The change also reflects a growing concern among women about not giving up their own property protection. In many cases, the decision to formalize rules before marriage is accompanied by a more critical reading of economic asymmetries within relationships. This includes everything from the fear of confusion between personal assets and common assets to the perception that lack of financial control or the abusive use of assets can become a tool of pressure within married life.

This point is important because the protection patrimonial is not limited to the hypothesis of divorce. It also covers situations of debt, business administration, succession and responsibility for assets acquired before the union. The pact is not a break clause. It is an organizational tool. It helps to define what will be shared, what will remain individual and what criteria will guide the couple’s economic life.

A planning tool for the couple

The lawyer highlights that resistance to the pact often arises from a mistaken idea about its meaning. “There is a tendency to interpret the document as an announcement of separation, when, in fact, it works as a transparent agreement on the property effects of marriage. The more information and legal awareness there is at the beginning of the relationship, the less chance of frustration and conflict later”, he says.

The growth of prenuptial agreements therefore indicates more than a legal trend. It signals a transformation in behavior. Instead of treating property as a forbidden topic until a problem arises, more couples have chosen to discuss this topic at a time when there is still dialogue, planning and real possibility of consensus. For many women, this also represents a concrete way of participating in marriage without giving up their own protection.
