In re E.R., 2019 Ohio 4491

Unmarried parents of E.R.; in 2013 the juvenile court designated Mother as legal custodian and granted Father visitation.
After repeated communication breakdowns, Father filed motions (2015, 2017) seeking more parenting time and access to records; parties resolved some disputes by agreed entries.
Father filed a motion to reallocate parental rights in July 2017; after a two-day bench trial the magistrate awarded legal custody to Father.
Mother filed timely objections; the juvenile court sustained them, finding no "substantial" change in circumstances and retaining Mother as custodian.
The magistrate had found a change in circumstances based on Father’s need to seek court intervention, the child’s transition to school age, and Mother’s increasing hostility.
The appellate court reversed, holding the juvenile court applied a higher "substantial" standard than R.C. 3109.04 requires, and remanded for application of the proper standard.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the juvenile court erred in denying reallocation by requiring a "substantial" change in circumstances	Father: magistrate found bona fide change (court intervention, child aging, Mother’s hostility) warranting custody reallocation	Mother: relationship always strained; no change beyond ongoing tensions; no basis to modify custody	Appellate court: juvenile court imposed a higher "substantial"-change standard than statute requires; reversed and remanded

Davis v. Flickinger, 77 Ohio St.3d 415 (Ohio 1997) (R.C. 3109.04 requires a finding of a "change in circumstances," not a higher "substantial" change standard)
Wyss v. Wyss, 3 Ohio App.3d 412 (10th Dist. 1982) (changed conditions must be substantiated, continuing, and materially adverse to the child)
Beekman v. Beekman, 96 Ohio App.3d 783 (4th Dist. 1994) (residential parent presumed to promote both parents’ affection; undermining that presumption can constitute a change in circumstances)
