What is the legal definition of an "intimate relationship?"
An intimate relationship includes heterosexual and same-sex couples who are/were dating but do not have a child in common. An "intimate" relationship does not have to mean a sexual one. To decide if a relationship is intimate, the judge will look at the nature (type) of the relationship, and how often and for how long the people in the relationship were in contact.*
Since judges can interpret the word "intimate" differently, a broad range of people may be able to file against each other that you might not expect. For example, in one case, a judge ruled that a man's new girlfriend could file against his ex-girlfriend who harassed her since both women had children with the man and the new girlfriend helped raise the ex-girlfriend's children.**
