When you hear the term “domestic violence,” you probably think of intimate partner violence. Domestic violence is commonly used to mean violence between two people who are in a romantic relationship. However, under Illinois criminal law, domestic violence can refer to violence between any two people who have a domestic relationship of any kind. This includes people who have a family relationship, such as parents and children, siblings, or cousins. It also includes people you are related to by marriage – your in-laws.

This is especially common during the holidays when family members who are normally able to avoid each other are brought together.
