Domestic violence means that in a relationship or marriage, one or both of the partners uses physical, sexual or psychological violence to try to get power or control over the other or due to losing their temper. Domestic violence can occur in heterosexual and same-sex relationships. There is often a predictable pattern or cycle of violence in a relationship and the abuse tends to get worse over time. Domestic violence can be also a factor to be homelessness, as pointed out by Principles 15 of the Yogyakarta Principles.
