An annulment does not end a marriage—it asks a court to declare that the marriage was never valid in the first place. Ohio reads that claim narrowly: the reason has to be one of six listed in the statute, and it has to have existed on the day of the wedding. What happened afterward matters only as a defense.
What a Court Decides in an Annulment
The statute speaks of two outcomes in one sentence: a court may determine that a marriage is void, or it may grant a judgment of nullity (R.C. 3105.34). Either way the court is deciding something about the marriage’s validity at the outset—not ending a valid marriage, which is what a divorce decree does.
That is why an annulment is not simply a faster divorce. It is a different claim with a different subject: you are proving something about the wedding day, not describing how the marriage went afterward.
The Six Grounds Under R.C. 3105.31
The statute limits annulment to causes “existing at the time of the marriage” and then lists six:
- Age. A party was under the age at which persons may be joined in marriage (R.C. 3101.01).
- A prior marriage still in force. A former husband or wife of either party was living, and that marriage was then and still is in force.
- Adjudicated mental incompetence. A party had been adjudicated mentally incompetent.
- Fraud. A party’s consent to the marriage was obtained by fraud.
- Force. A party’s consent was obtained by force.
- Non-consummation. The marriage was never consummated, although otherwise valid.
Notice what is missing. Incompatibility, living apart for a year, adultery, extreme cruelty—those are divorce grounds under R.C. 3105.01. None of them supports an annulment. A marriage that was valid when it began and later stopped working is a divorce case, however short it lasted.
Cohabitation Can End the Claim
Five of the six grounds carry the same escape clause: the claim fails if the parties cohabited as husband and wife afterward. For age and adjudicated incompetence, the cure is cohabitation after the party reaches the statutory age or is restored to competency. For fraud, it is cohabitation with full knowledge of the facts constituting the fraud. For force, it is cohabitation afterward, without qualification.
That makes the timeline the case. When did you learn the facts? Did you stay in the house? A party who remains for a year after discovering the fraud has usually answered the question the statute asks—and answered it against the claim.
The Deadlines Are Short (R.C. 3105.32)
Annulment also runs on a clock, and each ground has its own:
- Under age: by the party within two years after reaching the marriageable age; or by a parent, guardian, or other person having charge of the party at any time before that.
- Prior marriage in force: by either party during the life of the other, or by the former spouse.
- Adjudicated incompetence: by the party aggrieved, a relative, or a guardian, at any time before the death of either party.
- Fraud: within two years after discovery of the facts constituting the fraud.
- Force: within two years from the date of the marriage.
- Non-consummation: within two years from the date of the marriage.
Two years from the wedding date is not long. Cases that would have been strong on the merits get filed too late every year, because the deadline ran while the parties were still deciding what to do.
Residency and Where the Case Is Filed
The plaintiff in an action for divorce or annulment must have been an Ohio resident for at least six months immediately before filing, and the case is brought in the proper county under the Rules of Civil Procedure (R.C. 3105.03). The same section adds that the court may hear and determine the case whether the marriage took place, or the cause occurred, within or without the state—which matters for a couple who married elsewhere and later moved to the Dayton area.
What an Annulment Can Order
Children are covered expressly. On satisfactory proof of the causes in a complaint for divorce, annulment, or legal separation, the court must make an order for the disposition, care, and maintenance of the children of the marriage as is in their best interests, in accordance with R.C. 3109.04 (R.C. 3105.21). Parenting time is therefore part of an annulment case, on the same standards as any other family case.
A name can be restored. If the court determines the marriage is void or that a judgment of nullity ought to be granted, it may, in its discretion, restore any name the person had before the marriage (R.C. 3105.34).
Annulment or Divorce? Four Questions
- Did the ground exist on the wedding day? If the problem developed later, it is a divorce question.
- Is it one of the six in R.C. 3105.31? “We should never have married” is not a ground.
- Are you still inside the R.C. 3105.32 deadline for that ground?
- Have you cohabited since learning the facts? If so, the claim may already be gone.
If any answer is no, the practical route is usually divorce. For how the alternatives compare, see Divorce vs. Dissolution in Ohio and Legal Separation in Ohio.
A Few Things Annulment Does Not Mean
- Not a short-marriage rule. No Ohio annulment ground mentions how long the marriage lasted.
- Not an eraser. A judgment of nullity still comes with orders about children, and a party may still need a name-restoration order.
- Not a remedy for a mistake. Fault, regret, and incompatibility are divorce topics, not annulment grounds.
Getting Started
Annulment cases turn on documents and dates: the marriage certificate, when each party learned what, where each party lived, and whether there was any earlier marriage. Bring those to a consultation and the analysis can usually be done in one sitting.
