An annulment treats the marriage as if it never happened. Ohio courts grant annulments only on the limited grounds in R.C. 3105.31. Clinton County annulment cases are e-filed through efile.henschen.com and follow the same complaint-and-service process as divorce. Contact the Clerk at (937) 382-2316 to confirm any case-specific filing requirements.

How do I file for annulment in Clinton County, Ohio?

E-file a Complaint for Annulment with the Clinton County Court of Common Pleas at 46 South South Street, Suite 304, Wilmington, OH 45177, through efile.henschen.com. Clinton does not publish a separate annulment form — use the Ohio Supreme Court divorce complaint (Form 6 without children, Form 7 with children) and change the caption to "Annulment." The body must plead one of the five R.C. 3105.31 grounds: underage at marriage, bigamy, mental incompetency, fraud or duress in obtaining consent, or non-consummation. Include the local Case Designation Form and Personal Identifier Form. Filing fees are $300 without children and $400 with children.

Hire Gavvl Law for a Clinton County annulment

An annulment treats a marriage as if it never happened, and Ohio courts grant one only on the five limited grounds in R.C. 3105.31 — underage at marriage, bigamy, mental incompetency, fraud or duress in obtaining consent, or non-consummation. Clinton County publishes no annulment form, so the case is built on the Ohio divorce complaint (Form 6 or Form 7) with the caption changed to "Annulment," e-filed through efile.henschen.com with the local Case Designation and Personal Identifier forms. Gavvl Law pleads the right ground so the case is not dismissed out of the gate.

Pleading a real R.C. 3105.31 ground. Clinton County will dismiss an annulment that does not plead one of the five statutory grounds — "we made a mistake" is not a ground. We match your facts to the correct ground and draft the complaint body so the petition survives, or we tell you honestly when a divorce or dissolution is the realistic path instead.
Watching the statute's timing limits. R.C. 3105.31 puts strict timing limits on certain grounds — the underage and non-consummation grounds generally must be raised before a party reaches majority or continues living together. We read the statute against your dates before filing so a missed deadline does not sink an otherwise valid claim.
Protecting children even if the marriage is voided. Under R.C. 3111.03 a child born during the alleged marriage is still presumed the child of both parties, so custody, parenting time, and child support are decided just as in a divorce. We file the parenting affidavits, health-insurance affidavit, support worksheet, and a parenting plan so those issues are resolved.

If none of the five R.C. 3105.31 grounds fits, you cannot annul the marriage in Ohio — but we can pivot the same intake straight into a Clinton County divorce or dissolution without wasting your time. Every case is a flat fee approved up front, with payment plans and financing available.

Flat-fee options

Flat-fee limited scope: we draft and file your complaint for annulment to have the marriage declared void. You appear at any hearings yourself.

Complaint for annulment: $1,750

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.

How to File Annulment in Clinton County

Verify a R.C. 3105.31 ground applies. Underage at marriage, bigamy, mental incompetency, fraud or duress, or non-consummation. If none fits, annulment is not available.
Check the statute's timing limits. Several grounds must be raised within a fixed period after discovery or before continued cohabitation. Read R.C. 3105.31 carefully or consult an attorney.
Draft the complaint. Use Ohio SC Form 6 (no children) or Form 7 (with children) and change the caption to "Annulment." In the body, plead the specific R.C. 3105.31 ground and the supporting facts.
E-file through efile.henschen.com with the local forms. Upload the complete packet (including Case Designation Form and Personal Identifier Form) and pay the filing fee ($300 / $400).
Plan for children even if annulled. If children were born during the alleged marriage, file the parenting affidavits, Health Insurance Affidavit, child support worksheet, and a proposed parenting plan — the court still has to resolve those issues.

Clinton County Practice Notes

Grounds are strictly limited. Ohio courts will dismiss an annulment that does not plead one of the five R.C. 3105.31 grounds. "We made a mistake" is not a ground — file a divorce or dissolution instead.
Watch the timing limits. R.C. 3105.31 imposes specific timing limits on certain grounds — for example, the underage and non-consummation grounds must generally be raised before a party reaches majority or starts cohabiting. Read the statute carefully or call us before filing.
Children are still legitimate. Even if the court grants annulment, R.C. 3111.03 presumes a child born during the alleged marriage is the child of both parties. Custody, parenting time, and child support are allocated just like in a divorce.
