Brazilian Congress Passes Law Recognizing the Growing Importance of Pets

Brazil's Congress passed a law Tuesday giving judges the authority to divide custody of pets between separating couples, placing the country at the forefront of a global legal reckoning over whether animals belong in family courts or in property law.

The measure treats pet disputes the way child custody proceedings have long operated: when a separating couple cannot agree on who keeps the animal, a judge steps in. Under the new law, the court will "determine the shared custody arrangement and the equitable distribution of the animal's maintenance expenses between the parties." That means vet bills, food costs, and living conditions all become matters for judicial review — not just who technically purchased the animal.

To qualify for shared custody consideration, the animal must have spent the majority of its life with the couple. The law also draws a firm line around safety: shared custody will not be granted in cases of prior criminal records or a history or risk of domestic violence.

Lawmakers pointed to an increase in pet custody disputes in courts, but framed the law more broadly as a response to "changes that have occurred in Brazilian society in recent decades." The statement accompanying the legislation noted that couples with fewer children tend to have closer relationships with their animals, "often considered true family members."

The scale of Brazil's pet population gives that language concrete weight. The country of 213 million people has some 160 million pets, mostly dogs, according to the Instituto Pet Brasil. That near parity between people and pets is not incidental to the law's passage. Some 92% of Brazilian pet owners see themselves as "parents" of their pets, according to data from Mintel.

The practical architecture of the law will stress-test Brazilian family courts in new ways. Judges accustomed to evaluating parental fitness through school records and household stability must now weigh daily care routines, veterinary histories, and housing conditions to determine what constitutes an equitable split. The law does not define a hierarchy among those factors, leaving that discretion to the bench on a case-by-case basis.

The implications extend well beyond Brazil. In the United States, most states still classify pets as personal property in divorce proceedings, though a handful, including Alaska, California, and Illinois, have passed laws instructing courts to consider an animal's wellbeing. Brazil's new framework, which mandates judicial review of maintenance costs and living arrangements, goes further than most of those statutes by treating custody and financial responsibility as inseparable obligations. How Brazilian courts handle enforcement, particularly when one partner relocates or stops paying their share of expenses, will be closely watched by legal reformers pushing for similar changes elsewhere.
