An annulment declares that a marriage was never legally valid — different from a divorce, which ends a valid marriage. Ohio allows annulment only for specific reasons. In Hamilton County you file in the Court of Domestic Relations: a Complaint for Annulment with children (CDR Form 1.12) or without children (Form 1.13).

How do I get an annulment in Hamilton County, Ohio?

File in the Hamilton County Court of Domestic Relations (800 Broadway, (513) 946-9150): a Complaint for Annulment — With Children (CDR Form 1.12) or Without Children (Form 1.13), plus the Affidavit of Property and Debt (4.1), Affidavit of Income/Expenses (7.3), and Questionnaire (1.1). Ohio (R.C. 3105.31) allows annulment only for specific grounds — underage marriage, bigamy, mental incompetence, fraud, force, or a marriage never consummated — and several have short deadlines. If you don't qualify, divorce or dissolution is the usual path.

Hire Gavvl Law for your Hamilton County annulment

An annulment declares that a marriage was never legally valid — different from a divorce, which ends a valid marriage — and Ohio allows it only for specific grounds under R.C. 3105.31, several with short deadlines. In Hamilton County you file in the Court of Domestic Relations: a Complaint for Annulment — With Children (CDR Form 1.12) or Without Children (Form 1.13). Gavvl Law confirms you have grounds, prepares the complaint and supporting affidavits, and files it correctly — a flat fee approved up front, or full representation if the annulment is contested.

Confirming you actually have grounds. Ohio limits annulment to specific grounds — underage marriage, bigamy, mental incompetence, fraud, force, or a marriage never consummated (R.C. 3105.31) — and several carry short deadlines you can miss. We check your situation against the statute first, because if you don't qualify, a divorce or dissolution is the realistic path and we'll tell you straight.
The correct complaint, with or without children. We file Form 1.13 when there are no minor children and Form 1.12 when there are, each with the Affidavit of Property and Debt (4.1), the Affidavit of Income and Expenses (7.3), and the Questionnaire (1.1). Choosing the right complaint keeps the Court of Domestic Relations from bouncing your filing at the counter.
Children stay protected, whatever the ruling. Even if a marriage is annulled, children of the marriage remain legitimate and the court still decides custody and support in their best interest — which is why the with-children complaint adds the UCCJEA affidavit (2.1), the health-insurance affidavit (7.16), a support worksheet, and a parenting class. We handle all of it on a flat fee, or full representation if the case is contested.

Annulment is narrow and deadline-driven, so the first real value we add is an honest read on whether R.C. 3105.31 fits your facts — before you spend a filing deposit. When it does, we file the right complaint in the Court of Domestic Relations at 800 Broadway with the correct affidavits, and file the Fee Waiver (Form 1.22A) if the deposit is a hardship, so a valid annulment isn't lost to a technicality.

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.

Hamilton County Practice Notes

Annulment ≠ divorce. An annulment says the marriage was never legally valid; a divorce ends a valid marriage. Ohio limits annulment to specific grounds (R.C. 3105.31), several with short deadlines, and you must prove them. If you don't qualify, a divorce or dissolution is the usual route.
Children are still protected. Even if a marriage is annulled, children of the marriage remain legitimate and the court still decides custody, parenting time, and support in their best interest — which is why the with-children complaint (Form 1.12) adds the UCCJEA affidavit, health-insurance affidavit, and a support worksheet, and a parenting class is required.
Parenting class is required when children are involved (DR cases). Under R.C. 3109.053, both parents in a Domestic Relations case with minor children must complete an approved class: Parenting Through Transitions (in-person, 2.5 hours, $35 to the Clerk), Children in Between (online), or Two Families Now (online). Plaintiffs must file proof within 42 days of filing; defendants within 42 days of service. Certification is valid for 2 years.
