Filing for Annulment in Fairfield County

Fairfield County, Ohio · Lancaster

An annulment treats the marriage as if it never happened. Ohio courts grant annulments only on the limited grounds in R.C. 3105.31. Fairfield County annulment cases are filed at the DR Division on the 4th floor of the Hall of Justice in Lancaster, and follow the same complaint-and-service process as divorce. Fairfield does not publish a separate annulment form — use Ohio SC Form 4 (no children) or Form 5 (with children) with the caption changed to "Annulment" and the body pleading one of the five R.C. 3105.31 grounds.

One party was under the legal age to marry without the required consent.
One spouse was already legally married to someone else when the ceremony took place (bigamy).
One spouse was mentally incompetent at the time of the marriage.
Consent to marry was obtained by fraud or duress.
The marriage was never consummated.

If none of the R.C. 3105.31 grounds applies, you cannot annul the marriage in Ohio — file a Divorce or Dissolution instead. See Fairfield County divorce.

How to File Annulment in Fairfield 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 4 (no children) or Form 5 (with children) and change the caption to "Annulment." Plead the specific R.C. 3105.31 ground and the supporting facts.
Add Fairfield's locals. Personal Identifier Form, Notice of Filing for Family File, Affidavit 1, Affidavit 2 — and with children, Affidavit 3, Affidavit 4, the child support worksheet, SETS form, and a parenting plan.
Print everything single-sided and file at the 4th Floor Clerk. Pay the cost deposit (~$300) or file an Affidavit of Indigency.

Fairfield 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.
Use Fairfield's locals. The Personal Identifier Form, Notice of Filing for Family File, and (for children's cases) the SETS form are required the same way as in a divorce.

Frequently Asked Questions

What are the residency requirements to file in Fairfield County?: For divorce, legal separation, or annulment, you or your spouse must have lived in Ohio for at least 6 months and in Fairfield County for at least 90 days before filing. Dissolution only requires the 6-month Ohio residency.
How much does it cost to file in Fairfield County?: Filing fees are approximately $300, though the exact amount may vary by case type (with or without children). Call the Clerk of Courts at (740) 652-7440 for the current fee. An Affidavit of Indigency is available to waive fees for qualifying low-income filers. Fax filings are accepted at (740) 652-7399.
Why won't the Clerk accept my paperwork?: Fairfield County Clerk will NOT accept forms printed on both sides of the paper. Every page must be single-sided. This is one of the most common reasons filings get rejected at the counter — reprint anything that's double-sided before you go in.
When do I file in Fairfield Juvenile Court instead of DR?: If the parents were never married, custody, parenting time, child support, and paternity are filed in the Fairfield County Juvenile Court on the 3rd Floor of the same Hall of Justice in front of Hon. Terre L. Vandervoort. If you were married, those issues travel with the divorce, dissolution, legal separation, or annulment in the DR Division on the 4th Floor (Hon. Laura B. Smith). Judge Vandervoort uniquely serves as both Judge and Clerk of the Juvenile/Probate Courts.
