How long must I have lived in Arizona prior to filing for divorce in an Arizona court?

At least one of the parties to the action for divorce must have resided in the State of Arizona for at least ninety (90) days prior to the filing of the action. (A.R.S. 25-312). Unless the parents agree differently, the decisions on what happens with a child in a divorce, including custody, parenting time and child support, will be governed by the child’s “home state”, which is wherever that child has lived for the past 6 months. (A.R.S. 26-1002.7)
