Grandparent & Non-Parent Custody in Marion County, Ohio

Marion County, Ohio · Marion

Sometimes a child needs to live with a grandparent, relative, or other adult. The Juvenile side of the Family Division can grant legal custody to a non-parent under R.C. 2151.23, while parents usually keep residual rights.

Can a grandparent or relative get legal custody in Marion County, Ohio?

Yes. File a complaint or motion for legal custody to a non-parent on the Juvenile side of the Family Division (222 W. Center St.) under R.C. 2151.23, with the Case Designation (Form F) and affidavits — the closest published deposit is the $268 Allocation of Parental Rights fee (confirm the exact amount with the court). The court may appoint a Guardian ad Litem and/or order a Family Court Services investigation, and a non-parent must generally show that parental custody is not in the child's best interest. For short-term needs, a Grandparent Power of Attorney or Caretaker Authorization Affidavit may work without a full case. Legal custody is not adoption — the parents keep residual rights.

How to File Grandparent / Non-Parent Custody in Marion County

Marion County Practice Notes

Legal custody is not adoption. A non-parent who receives legal custody can make day-to-day decisions and care for the child, but the parents keep residual rights (companionship and a support duty). Adoption permanently ends parental rights and is a separate Probate matter.
Confirm the non-parent deposit and expect a GAL. The $268 allocation deposit is the closest published figure — confirm the exact deposit for a non-parent legal-custody filing with the court. A Guardian ad Litem is common because non-parents face a higher legal bar.

Frequently Asked Questions

Can a grandparent or relative get custody in Marion County?: Yes. The Juvenile side of the Family Division can grant legal custody to a non-parent (a grandparent, relative, or other suitable adult) under R.C. 2151.23 when parental custody is not in the child's best interest or a parent is unsuitable. A Guardian ad Litem is common in these cases.
Is there a quicker option than a full custody case in Marion County?: For short-term, informal needs, a Grandparent Power of Attorney or a Caretaker Authorization Affidavit (statewide standalone forms) may let a relative care for a child without a full court case. They are limited and revocable, so a court custody order is needed for anything long-term.
Is non-parent legal custody the same as adoption in Marion County?: No. Legal custody to a non-parent lets you care for and make day-to-day decisions for the child, but the parents keep residual rights (companionship and a duty to support). Adoption permanently ends parental rights and is a separate Probate matter.
When does Marion County appoint a Guardian ad Litem?: In a contested custody case, the court can appoint a Guardian ad Litem — a court-appointed attorney who investigates and recommends a parenting plan in the child's best interest. A GAL appointment carries a $2,500 deposit (Rule 3), typically allocated between the parents. The court may also order a Family Court Services custody investigation.
What does it cost to file a custody or parentage case in Marion County?: A complaint or motion for Allocation of Parental Rights and Responsibilities carries a $268 deposit (Rule 3). Reopening a dormant case is $210. If a Guardian ad Litem is appointed, a $2,500 deposit applies. A fee waiver (Affidavit of Poverty) is available. Confirm current amounts with the Clerk at (740) 223-4070.
