Establishing Paternity in Ashtabula County

Ashtabula County, Ohio · Jefferson

When parents were never married, legally establishing the father (parentage) comes first — it unlocks custody, parenting time, and child support. In Ashtabula County, parentage is handled in the combined Juvenile-Probate Court at 4717 Main Ave., Ashtabula (R.C. Ch. 3111). You can establish it three ways: a voluntary Acknowledgment/Joint Declaration of Paternity, an administrative process through the Ashtabula County CSEA (440-994-1212) with genetic testing, or a judicial parentage action that can decide custody and support at the same time.

How do I establish paternity in Ashtabula County, Ohio?

There are three routes. Both parents can voluntarily sign an Acknowledgment of Paternity or the county's Joint Declaration of Paternity, which has the force of a court order once final. The Ashtabula County CSEA (440-994-1212) can order genetic testing and establish paternity and a support order administratively. Or you can file a Complaint for Parentage in the Juvenile-Probate Court at 4717 Main Ave., Ashtabula — a new case is $130 plus a $95 paternity court cost — which can order genetic testing and decide parentage, custody, parenting time, and support together. A Civil Fee Waiver is available if you can't afford the deposit.

Ashtabula County Practice Notes

Three routes to parentage. Acknowledgment/Joint Declaration of Paternity (voluntary), administrative establishment with genetic testing through the Ashtabula County CSEA (440-994-1212), or a judicial parentage action in the Juvenile-Probate Court. Genetic testing is available whenever paternity is disputed.
Parentage unlocks custody and support. Until paternity is established, the Juvenile-Probate Court can't allocate custody or set support. A judicial parentage action can decide parentage, custody, parenting time, and support together, saving a second filing.

Frequently Asked Questions

How do I establish paternity in Ashtabula County?: Three routes. Parents can voluntarily sign an Acknowledgment of Paternity (or the county's Joint Declaration of Paternity), which has the force of a court order once final. The Ashtabula County CSEA (call center 440-994-1212) can order genetic testing and establish paternity and support administratively. Or you can file a parentage action in the Juvenile-Probate Court, which can order genetic testing and decide parentage, custody, parenting time, and support together.
Do I file custody in the DR Division or the Juvenile-Probate Court?: It depends on whether the parents were ever married. If you are (or were) married to the other parent, custody, parenting time, and child support are decided inside the divorce, dissolution, or legal separation in the General & Domestic Relations Division at 25 West Jefferson Street, Jefferson. If you were never married, parentage and custody are handled by the combined Juvenile-Probate Court at 4717 Main Ave., Ashtabula. Grandparent and other non-parent custody is always filed in the Juvenile-Probate Court.
How much does a Juvenile-Probate Court case cost in Ashtabula County?: The Juvenile Division's fee schedule (effective 07-10-2024) charges $130 for a new custody, visitation, parental-rights, or support case; $25 for general motions; $50 for objections or a motion to set aside a magistrate's order; and $25 to file a notice of relocation out of county. Court costs add on top — paternity $95, private custody $95, publication $80, certified mail $15. A Civil Fee Waiver / Financial Disclosure (CFW) is available. Confirm amounts before filing.
How is child support calculated in Ashtabula County?: Ashtabula uses Ohio's statewide 2024 Income Shares Model — there is no county-specific formula. Run the official worksheet at ohiochildsupportcalculator.ohio.gov using both parents' gross incomes, parenting time, health-insurance, and child-care figures, then print and sign it for filing. A motion to establish or modify support must include a completed IV-D Application signed by the obligee (Local Rule 7.3) and a Health Insurance Affidavit. The Ashtabula County CSEA (440-994-1212) collects and enforces orders through wage withholding.
