How does child custody work in Marion County, Ohio?

Custody (the allocation of parental rights and responsibilities) is decided under the child's best interest (R.C. 3109.04). Married or formerly married parents resolve custody inside a divorce, dissolution, legal separation, or annulment; never-married parents file an Allocation of Parental Rights case on the Juvenile side of the Family Division (222 W. Center St.) for a $268 deposit (Rule 3). The court can order sole custody to one parent or approve shared parenting, and parenting time follows Local Rule 32B Options 1–5 by the child's age. Each parent completes parent education within 60 days (Rule 12), and a Guardian ad Litem may be appointed in contested cases.

Marion County custody, handled by Gavvl Law

Custody in Ohio is the allocation of parental rights and responsibilities, decided under the child's best interest (R.C. 3109.04), and in Marion County the one combined Family Division handles it on both the divorce and Juvenile tracks. Married parents resolve it inside a divorce or dissolution; never-married parents file a standalone allocation case on the Juvenile side for a $268 deposit. Gavvl Law files on the correct track and represents you on one flat fee agreed up front, with financing and full representation for contested cases.

The right track for your family. Married or formerly married parents resolve custody inside a divorce, dissolution, legal separation, or annulment, while never-married parents file an allocation case on the Juvenile side under R.C. 2151.23. Filing on the wrong track wastes time and money — we open the case where it belongs.
Sole custody or shared parenting, decided on evidence. The court can name one residential parent or approve shared parenting, always under the best-interest test in R.C. 3109.04. We build your case on that standard and choose between a Form 20 shared-parenting plan and a Form 21 sole-custody plan based on what your facts actually support.
Parenting time set by Rule 32B. Marion's default schedule comes from Local Rule 32B (effective 3/8/24), with Options 1 through 5 keyed to the child's age. We anchor your parenting time to the right option or justify a best-interest deviation, and attach the Parenting Addendum (Form K).

Contested custody in Marion often brings a Guardian ad Litem with a $2,500 deposit, and every parent must finish the Rule 12 parent-education course within 60 days of the Form I notice. We budget for the GAL, track the course to keep the case on schedule, and file a fee waiver if the $268 allocation deposit is out of reach.

Flat-fee options

Flat-fee limited scope: we draft and file the custody complaint or motion; you appear at any hearing.

Establish custody: $1,250
Modify custody: $1,450

Prefer full representation? An Ohio attorney can carry the entire case on a $3,500 retainer.

Split any flat fee with Gavvl Direct — our in-house plan at 19% APR, $500 minimum — on a 60%-down schedule of 18 weekly, 8 bi-weekly, or 4 monthly payments, or full financing where work begins once 60% is paid. Affirm, Klarna, and PayPal Pay Later are also available through LawPay.
