Establishing Paternity in Seneca County

Seneca County, Ohio · Tiffin
When parents were never married, parentage, custody, parenting time, and child support are decided by the Seneca County Juvenile Court (103 E. Market St., Tiffin; (419) 447-4912), not the Domestic Relations Division. Although these cases are filed in Juvenile Court, the Ohio Rules of Civil Procedure govern them. Establishing paternity is the gateway: until parentage is established, the court can't allocate custody or order support for the father.
How do I establish paternity in Seneca County, Ohio?
File a parentage action in the Seneca County Juvenile Court — using the Court's Pro Se Packet for Custody/Visitation (or the county Complaint for Parentage, ARPRR & Parenting Time) — with a Motion, Memorandum in Support, Child Custody Affidavit, Request for Service, and Personal Identifier Sheet, plus the $178 per case/child fee (Local Rule 7.04). Paternity can also be established by a signed Acknowledgment of Paternity or genetic testing. Once parentage is established, the same case can set custody, parenting time, and child support; support is administered by the Seneca County CSEA.
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 |

Seneca County Practice Notes
- Civil Rules govern parentage cases — even in Juvenile Court. Under Juv.R. 1(C) and Local Rule 1.08(C), proceedings to determine the parent-child relationship run under the Ohio Rules of Civil Procedure, not the Juvenile Rules, and Civ.R. 75 does not apply (Local Rule 7.02). Temporary parental-rights orders rest on R.C. 3109.043 and Juv.R. 13 via Juv.R. 45.
- Every custody motion needs the full Local Rule 7.04 package. A parentage or custody motion is commenced with a Motion, Memorandum in Support, Child Custody Affidavit, Request for Service, Personal Identifier Sheet, and the per-case/child fee. Pro se motions must be typed, legible, original plus one copy, and notarized (Local Rule 5.01).
- Support runs through the Seneca County CSEA. Child support is calculated under R.C. Chapter 3119 and paid through the Seneca County Child Support Enforcement Agency (900 E. CR 20, Tiffin; (419) 447-5011) and Ohio Child Support Payment Central, with the statutory administrative fee. Direct parent-to-parent payments are treated as gifts.

Unmarried parents (parentage, custody, parenting time, support), abuse/neglect/dependency, and delinquency go to the Juvenile Court; adoptions go to the Probate Court — Juvenile and Probate are a combined court under Judge Jay A. Meyer at the same address ((419) 447-4912 Juvenile / (419) 447-3121 Probate).
