Clark County, Ohio · Springfield
If the parents were not married when the child was born, Ohio law requires a separate step to legally establish a father before a court can order custody, parenting time, or child support. In Clark County, parentage cases are filed in the Juvenile Section using the Complaint for Parentage, Custody & Parenting Time (Form 23).
How do I establish paternity in Clark County, Ohio?
File a Complaint for Parentage, Custody & Parenting Time (Supreme Court Form 23) in the Clark County Juvenile Section. The same complaint legally establishes the father and lets the court allocate custody and parenting time and set child support in one case. File it with the Parenting Proceeding Affidavit (Affidavit 3), the Health Insurance Affidavit (Affidavit 4), the Affidavit of Income & Expenses (Affidavit 1), and the Ohio Child Support Worksheet. Juvenile filing amounts are set by the Juvenile Section, and there is a $25 non-refundable fee for court-appointed counsel if you qualify.
Ohio Custody by the Numbers
- Best interest The single standard that governs every Ohio custody decision Source: Ohio Revised Code § 3109.04
- No set age There is no age a child can choose a parent — the judge weighs a mature child's wishes Source: Ohio Revised Code § 3109.04(B)
- Change in circumstances Required, plus a best-interest finding, before the residential parent can be changed Source: Ohio Revised Code § 3109.04(E)(1)
- Shared parenting Either parent may ask the court for a joint parenting plan Source: Ohio Revised Code § 3109.04(G)
Compare Types of Custody in Ohio
| Custody type | Who makes major decisions | Where the child lives | Best when |
|---|---|---|---|
| Shared parenting | Both parents jointly, under a written plan | Time is split per the plan (not always 50/50) | Parents can communicate and cooperate on decisions |
| Sole legal & residential | One parent | Primarily with that parent | One parent is unable or unwilling to co-parent |
| Split custody | Each parent for the child in their care | Siblings are divided between the two homes | Rare — only when it serves each child's best interest |
| Legal custody to a non-parent | The relative or caregiver granted custody | With the non-parent caregiver | Neither parent can safely care for the child |

Clark County Practice Notes
- One complaint covers parentage, custody, and support. Clark County's Form 23 is titled "Complaint for Parentage, Custody & Parenting Time." Filing it lets the Juvenile Section establish the father and, in the same case, allocate custody and parenting time and set child support.
- Where to file. Paternity for never-married parents is handled in the Clark County Juvenile Section (clarkohiojuvcourt.us), not in the Domestic Relations Adult Section. The Adult Section handles parentage issues only when they arise inside a divorce or dissolution.
- Support follows once parentage is established. Once the court establishes the father, it can set child support on the Ohio Child Support Worksheet under the 2024 Income Shares Model and allocate health-insurance coverage for the child.
Frequently Asked Questions
- How do unmarried parents establish paternity and custody in Clark County?
- File a Complaint for Parentage, Custody & Parenting Time (Supreme Court Form 23) in the Clark County Juvenile Section. The same complaint can legally establish the father, allocate custody and parenting time, and set child support. File it with the Parenting Proceeding Affidavit (Affidavit 3), the Health Insurance Affidavit (Affidavit 4), the Affidavit of Income & Expenses (Affidavit 1), and the Ohio Child Support Worksheet.
- When do I file in the Juvenile Section instead of DR?
- If you were never married to the other parent, custody, parenting time, and child support are filed in the Clark County Juvenile Section (clarkohiojuvcourt.us), not in DR. If you were married, those issues travel with the divorce, dissolution, legal separation, or annulment in DR at 101 N. Limestone Street.
- How does a Clark County court decide custody and parenting time?
- Ohio courts allocate parental rights using the R.C. 3109.04(F) best-interest factors — each parent's wishes, the child's wishes when of sufficient age, the child's relationships and adjustment to home and school, the physical and mental health of everyone involved, which parent is more likely to honor parenting time, and any history of abuse. In Clark County these issues are decided in the Adult Section for married parents and the Juvenile Section for never-married parents.
- How much does it cost to file in Clark County DR?
- Dissolution is a $350 deposit (not a flat fee — the balance is refunded after costs). For divorce, legal separation, annulment, and post-decree motions, deposits are set by the Clerk — call (937) 521-1753 for the current amount before filing. CPO petitions are free. Juvenile court charges a $25 non-refundable application fee for court-appointed counsel.
