Family law: parenting time; grandparenting time; modify. Amends secs. 2, 7 & 7b of 1970 PA 91 (MCL 722.22 et seq.).

HB 4217 amends Michigan's Child Custody Act to protect military parents' custody rights during deployment. It defines "deployment" as 60-540 days of active duty (including National Guard) and prohibits courts from modifying custody arrangements based on a parent's absence due to deployment. The bill requires courts to grant stays in custody proceedings during deployment unless there's clear evidence the change is in the child's best interest, and explicitly states deployment status cannot be considered in custody decisions. This directly affects military parents and their children involved in custody cases in Michigan. The changes apply to Sections 2, 7, and 7b of the Child Custody Act.
