The two ended their 11-year marriage on Wednesday, when divorce paperwork was finalized.
Garth and Facinelli will split but continue their parental roles together, beyond what most couples would. They are keeping a joint bank account to care for their children and cover their education.
They also agreed to 50/50 custody and said they don't need a formal custody arrangement.
Garth and Facinelli both denied spousal support and will pay the same amount into the joint account. They share three children: 15-year-old Luca, 10-year-old Lola and six-year-old Eve.
