Primary law and terminology
MCL § 722.23 (best-interest factors); Child Custody Act of 1970. In Michigan, courts generally describe the schedule as a parenting time order. The court's decision is based on the child's best interests, not simply a parent's preferred percentage of time.
Joint custody and parenting time
Joint custody must be considered when requested; the established custodial environment controls the burden of proof.
Child preference
A reasonable preference of a child of sufficient age is factor (i).
Relocation and move-away cases
MCL § 722.31 — the '100-mile rule' — requires court approval for a move over 100 miles or out of state.
Changing an existing order
Proper cause or a change of circumstances first; then clear and convincing evidence if an established custodial environment exists.
Where to file
Under the UCCJEA the child generally must have lived in the state for the 6 months before filing (or since birth, if younger). The Friend of the Court office investigates and makes recommendations in custody cases.
