The name and penalty for bodily injury change with the damage done to the victim’s body and health. Knowing how minor, serious, and very serious injuries differ helps anyone who has been attacked, especially at home, to get a forensic examination on time, document the facts methodically, and protect their family from the consequences of violence.

What the law means by bodily injury

Article 129 of Brazil’s Penal Code defines bodily injury (lesão corporal) as an offense against another person’s physical integrity or health. The offense covers visible harm, such as a cut, a fracture, or a bruise, as well as damage to physical or mental health that leaves no outward mark. That is why a blow that does not draw blood can still be a crime, as long as it causes significant pain or impairs the way the body functions.

Bodily injury must be distinguished from what Brazilian law calls vias de fato (physical aggression that causes no injury), such as a shove that does not hurt. With bodily injury, there is a result in the body or in the person’s health. With vias de fato, there is physical violence but no measurable harm. This line is usually drawn by the forensic examination, which certifies whether or not the person’s physical integrity was harmed.

When the attack happens within the family, against a spouse, partner, parent, grandparent, child, grandchild, or someone the aggressor lives with, the law itself treats the offense more harshly. Paragraph 9 of Article 129 creates the offense of bodily injury in a domestic violence context, with a higher penalty than ordinary bodily injury, even when the physical harm is minor. The emotional closeness that should protect a person instead weighs against the one who attacks.

Minor, serious, and very serious injuries: grading by result

The severity of the injury determines its classification and, with it, how harshly the criminal law responds. The test is not how much the aggressor meant to hurt, but the actual result found on the victim’s body. This makes the forensic examination a central piece of evidence, because it describes the extent of the harm in technical terms.

A minor injury is the form set out in the caput (the main clause) of Article 129. It covers attacks that do not fall into the more severe categories, such as scrapes, bruises, and small cuts that heal without lasting effects. In its ordinary form, the penalty is detention of three months to one year, increased when the offense occurs in a domestic context.

A serious injury, described in paragraph 1, requires an aggravated result. It applies when the victim is unable to carry out ordinary activities for more than thirty days, when the victim’s life is endangered, when the victim suffers permanent weakening of a limb, sense, or function, or when the attack causes a pregnant woman to give birth prematurely. The penalty becomes imprisonment (reclusão) of one to five years, reflecting the jump in severity.

A very serious injury, in paragraph 2, covers the most devastating results. These include permanent inability to work, incurable illness, loss or disablement of a limb, sense, or function, permanent disfigurement, and miscarriage caused by the violence. The penalty is imprisonment of two to eight years. There is also injury followed by death, in paragraph 3, when an attack not intended to kill ends up causing death, with a penalty of up to twelve years.

Understanding this scale matters because the same attack can be reclassified as the days go by. An injury first considered minor may turn out to be serious if recovery takes longer than thirty days or if a permanent aftereffect appears. For this reason, ongoing medical care and updated reports are not bureaucratic details. They shape the course of the case.

This grading also tells the victim and the family something: violence can be measured, and that measure carries proportional legal consequences. Recognizing that you are dealing with a serious or very serious injury changes how urgent the next steps are, what kind of protection you can request, and how large a claim for compensation you can pursue later.

That is why a blow that does not draw blood can still be a crime, as long as it causes significant pain or impairs the way the body functions.

The forensic examination and the weight of the evidence

In crimes that leave physical traces, the forensic examination (exame de corpo de delito) is indispensable. Article 158 of the Code of Criminal Procedure provides that when the offense leaves marks, an expert examination must be carried out, either directly or indirectly. A direct examination happens when the expert examines the victim’s body itself. An indirect one happens when the traces have already disappeared and the evidence is rebuilt from documents such as medical records and photographs.

Time is a decisive factor. Many traces, such as bruises and swelling, disappear within a few days. Going to the Medical-Legal Institute (the official forensic medical agency) or to a health facility as soon as possible preserves the evidence that the crime occurred. Every report, prescription, medical certificate, and photograph adds to the proof and helps show not only that an attack took place, but how serious it really was.

When the victim cannot get to the official institute at the right time, treatment at a hospital or health clinic is still valuable. The medical record, with its description of the injuries, serves as the basis for an indirect examination. Keeping these documents, with the dates and names of the professionals who provided care, strengthens your account and lowers the risk that the attack will be downplayed later.

Documenting the facts, step by step

The police report is the first formal record of the attack and should be as detailed as possible. The date, time, and place, a description of what happened, the names of any witnesses, and any mention of earlier attacks make up a consistent account. In domestic violence cases, the police station can refer the victim for a forensic examination, and the report can be the starting point for protective measures.

Law 11.340 of 2006, known as the Maria da Penha Law, provides for urgent protective orders that can be requested immediately, such as removing the aggressor from the home, prohibiting contact, and setting a minimum distance. These orders do not depend on the final outcome of the criminal case, and they serve to break the cycle of violence before it gets worse.

Organizing the evidence in chronological order helps show that the attack was not an isolated incident. Messages, audio recordings, photographs of the injuries, and accounts from neighbors or relatives, when gathered with dates, paint a picture of the context. This body of evidence guides the technical work and makes it possible to determine correctly whether the injury was minor, serious, or very serious.

How the injury affects the family

Violence that causes bodily injury rarely stays within the criminal sphere. Within a family, it ripples into decisions about child custody, visitation, support, and whether the relationship will continue at all. A proven attack can justify a divorce petition, a review of visitation arrangements, and limits on the aggressor’s contact with the children.

When there are minor children, violence against the mother or father affects how the child’s best interests are assessed. A history of aggression can support an order of sole custody, suspended visits, or a requirement that visits be supervised. What begins as a crime against physical integrity ends up directly influencing the family’s arrangements.

There is also the question of compensation. The victim can seek damages for the harm suffered, including medical expenses, treatment, and the emotional distress caused by the attack. The lasting effects of a serious or very serious injury, such as permanent disfigurement or inability to work, increase the extent of the loss and, therefore, of what can be claimed.

Protecting the family in this situation means working on both fronts together. On one side is the criminal response, which classifies and punishes the attack. On the other is the family-law and civil response, which reorganizes home life and seeks to repair the harm. Handling both together keeps the victim from having to relive the trauma again and again, and gives the protection strategy coherence.

Frequently Asked Questions

How can I tell whether my injury is minor, serious, or very serious?

The classification depends on the result found on the body, not on how the attack first appeared. The forensic examination report describes the extent of the harm and is the basis for classifying the injury. An injury can be reclassified if recovery takes longer than thirty days or if a permanent aftereffect appears, which is why continuous medical follow-up is important.

I missed my chance to go to the Medical-Legal Institute right after the attack. Can I still prove the injury?

Yes. When the traces have already disappeared, the law allows an indirect forensic examination, based on medical records, certificates, prescriptions, and photographs of the injuries. That is why every visit to a hospital or health clinic should be documented and saved, with the dates and the names of the professionals, so the evidence can be rebuilt later.

Does an attack at home change how the case is treated?

It changes it in several ways. An injury committed in a domestic context carries a harsher penalty and allows you to request urgent protective orders, such as removal of the aggressor and a ban on contact. In addition, proven violence affects family matters such as custody, visitation, and divorce, and can support a claim for compensation for the harm suffered.
