The Medium star confirmed her split from The Punisher actor earlier this month and after filing for divorce, Arquette requested full legal and physical custody of their seven-year-old daughter, Harlow.
Subsequent rumors suggested the former couple disagreed over how they should split custody of the youngster, but the actress is adamant the legal proceedings haven't turned bitter.
She tells E! Online, "We're both really good. I don't think people would even imagine that it could be so friendly and not weird."
