When a parent challenges the validity of a release of parental rights on the ground that it was not made knowingly or voluntarily, the parent alleges a concrete injury arising from the trial court’s order and qualifies as an aggrieved party for purposes of appellate jurisdiction.

In a published decision, the COA found that the Kent County Circuit Court erred in terminating a mother's parental rights under MCL 712A.19b(3)(l), where the mother had voluntarily released her rights to a different child under the Adoption Code.
