Background
Jacob Gruizinga and Ashlee Skinner shared joint legal and physical custody of their child under orders requiring them to consult on major decisions, follow medical providers’ recommendations, and notify each other of medical treatment. Their parenting-time arrangement gave Skinner five days with the child during one week and two days during the next.
Gruizinga sought changes to custody, parenting time, and support based on an incident involving Skinner’s then-boyfriend and a medical appointment at which the child received multiple school-required vaccinations. Skinner testified that she had ended the relationship, that she called Gruizinga when the child’s appointment was unexpectedly combined with another child’s appointment, and that Gruizinga arrived shortly afterward. Both parents also agreed that the existing parenting-time schedule was not working.
The trial court found no proper cause or change of circumstances warranting reconsideration of custody. It nevertheless found grounds to revise parenting time and ordered a week-on/week-off schedule. Gruizinga appealed both rulings.
The Court’s Holding
The Court of Appeals affirmed the denial of Gruizinga’s request to modify custody. The evidence did not show that Skinner’s former boyfriend posed an ongoing risk after their relationship ended. The vaccination incident also did not establish proper cause or a material change of circumstances: Skinner followed the medical provider’s recommendations, notified Gruizinga, and gave him an opportunity to attend. Gruizinga did not prove an agreement requiring the vaccinations to be administered one at a time.
The court also affirmed the revised parenting-time schedule. Because the week-on/week-off rotation did not significantly alter the number of parenting-time days or otherwise change custody, the trial court was not required to make findings on every statutory best-interest factor. It could decide the parenting-time issue by addressing the contested considerations relevant to the child’s best interests.
Key Takeaways
- A custody modification requires proper cause or a material change of circumstances with the potential to significantly affect the child’s well-being.
- A past incident involving a parent’s former romantic partner did not justify revisiting custody without evidence of an ongoing concern affecting the child.
- A parenting-time adjustment that does not amount to a custody change does not require findings on every statutory best-interest factor.
Why It Matters
The decision distinguishes the demanding threshold for reopening custody from the more flexible standards governing parenting-time adjustments. Disagreements over medical decisions or a parent’s former relationship will not necessarily justify a custody review unless the evidence shows a material, continuing risk to the child.
It also confirms that Michigan trial courts need not mechanically address every custody best-interest factor when revising parenting time without changing the child’s custody arrangement.
