Violence between the intimate partners is not a new phenomenom, the literature states that it has existed since the beginning of humanity. As a legacy of patriarchy, violence against woman in partnerships is more often mentioned than against men or same-sex partners. The aim of this document is to get acquainted whit violence between intimate partners, its manifestations, frequency and legislative regulation in the Croatian legal system through a review of the literature and legal regulations. Today, the authors and the legislator have defined various forms of violence in partnerships, and the legislator strives to sancion as many forms of violence as posible. The Croatian legal system distinguishes between violent behavior in the family as misdemeanors or criminal offenses - the difference is mostly reflected in the consequences for the victim and sanctions against the perpetrator. We are witnessing numerous legal changes that seek to sanction, but also prevent violence in intimate relationships and develop a zero tolerance rate for violence. A major challenge for combating violence is its non-reporting. Victims are tend to live long in violente relationships. Violence between partners is difficult to study on its own because it is mostly viewed thought the prism of domestic violence. This type od violence is a common occurrence, woman are more often victims, but they are also a bullies. The legislator is moving in the direction of havier sanctions and greater prevention. The biggest challenge is the dark number.
