Annulment in Shelby County

Shelby County, Ohio · Sidney

An annulment treats a marriage as void or voidable on narrow statutory grounds (R.C. 3105.31) — for example bigamy, an underage marriage without proper consent, fraud, force, or incapacity. It is distinct from divorce and dissolution and is fact-specific. Shelby County does not publish a self-help annulment packet, so confirm the grounds, proof, and process with the court or an attorney.

What are the grounds for annulment in Shelby County, Ohio?

Ohio allows annulment only under R.C. 3105.31: a spouse was already married (bigamy); a spouse was underage without proper consent; a spouse lacked the mental capacity to consent; consent was obtained by fraud; consent was obtained by force; or the marriage was never consummated. Most grounds carry a time limit. An annulment is a court order declaring the marriage was never legally valid — different from a divorce, which ends a valid marriage. It is filed in the Common Pleas Domestic Relations Division and follows the same cost-deposit and service rules as a divorce. Because the grounds and proof are narrow and statutory and the county does not publish a self-help annulment packet, confirm the process with the court at (937) 498-7221 or consult an attorney. Even if a marriage is annulled, the court still addresses parentage, custody, and support for any children.

Shelby County Practice Notes

Grounds are narrow and statutory. Ohio allows annulment only under R.C. 3105.31 (bigamy, underage without consent, mental incapacity, fraud, force, or non-consummation), and most grounds carry a time limit. The county does not publish a self-help annulment packet; confirm the grounds and proof with the court or an attorney.
Annulment is not divorce. An annulment declares the marriage was never legally valid; a divorce ends a valid marriage. If your marriage was valid, divorce or dissolution is the correct path, not annulment.
Children's rights are protected. Even if a marriage is annulled, the court still addresses parentage, custody, and child support for any children of the relationship. Those rights are not lost because the marriage was declared invalid.
