An annulment treats a marriage as if it was never valid, available only in narrow situations such as bigamy, fraud, or being underage. It is different from a divorce, which ends a valid marriage. In Miami County, an annulment is filed and heard in the General Division using the same complaint forms as a divorce.

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

File the same complaint used for divorce — Form 6 when there are no minor children, or Form 7 when there is at least one minor child — with the Miami County Clerk of Courts, (937) 440-6046, and the full Appendix A affidavit packet. Annulment is available only in narrow situations (such as bigamy, fraud, or being underage); the court decides whether grounds exist to treat the marriage as never valid. E-filing is mandatory as of June 1, 2026, and the deposit is set by the Clerk — confirm the current amount or file an Affidavit of Indigency.

Hire Gavvl Law for your Miami County annulment

An annulment treats a marriage as if it was never valid, and Ohio grants one only in narrow situations such as bigamy, fraud, or being underage — it is very different from a divorce, which ends a marriage the law recognizes. In Miami County an annulment is filed in the General Division on the same complaint forms as a divorce. Gavvl Law assesses whether you actually have grounds and files the case, on a flat fee with payment plans.

An honest read on whether you have grounds. Annulment is available only in limited circumstances, and the court decides whether grounds exist to treat the marriage as never valid. Before you spend anything, we measure your facts against Ohio's narrow grounds — bigamy, fraud, being underage, and a few others — so you pursue annulment only where it can actually succeed.
Filed on the divorce forms, with the full packet. An annulment uses the county's divorce complaint forms — Form 6 with no minor children or Form 7 with at least one — together with the Appendix A affidavit packet. We complete the complaint and affidavits correctly so the filing is accepted and the case is framed around your annulment grounds from the start.
Deposit confirmed, handled on a flat fee. Miami County's deposit is set by the Clerk and collected through the e-file system, which is mandatory as of June 1, 2026. We confirm the current amount at (937) 440-6046 — or file an Affidavit of Indigency if you cannot afford it — and handle the annulment on a flat fee, with full representation if your spouse disputes the grounds.

An annulment is heard by the General Division in Troy, the same court that handles divorces, because Miami County has no separate Domestic Relations court. We know how those judges evaluate the narrow grounds for treating a marriage as void and build your case so the proof matches what the court requires before it will set the marriage aside.

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.

Miami County Practice Notes

Annulment is narrow. An annulment says the marriage was never valid and is available only in limited situations such as bigamy, fraud, or being underage. Most cases that end a valid marriage are divorces or dissolutions, not annulments.
Filed on the divorce complaint forms. Annulment uses the same county complaint forms as divorce — Form 6 (no minor children) or Form 7 (with at least one minor child) — with the Appendix A affidavit packet, in the General Division.

Frequently Asked Questions

What is an annulment in Miami County?: An annulment treats a marriage as if it was never valid, and is available only in narrow situations such as bigamy, fraud, or being underage. It is different from a divorce, which ends a valid marriage. An annulment is filed on the same county complaint forms used for divorce (Form 6 without children or Form 7 with children) with the Appendix A affidavit packet.
What is the difference between divorce and dissolution in Miami County?: A dissolution is a no-fault, fully agreed end to a marriage: both spouses sign a Separation Agreement (and, with children, a parenting plan) before filing a joint Petition for Dissolution (Form 17), and the court holds a hearing 30–90 days later (R.C. 3105.64). A divorce is used when the spouses do not fully agree or one spouse files against the other; it can involve temporary orders, a pretrial, and a trial. If spouses stop agreeing during a dissolution, the case can convert to a divorce.
How many copies and what packet do I need to file in Miami County?: File the original plus four copies when there are minor children, or the original plus three copies when there are none (Local R. 8.01(F)). Every DR complaint, petition, or post-decree motion must also include the full Appendix A required-filings packet (income/expense and property affidavits, and — with children — the parenting and health-insurance affidavits, a support order, the IV-D application, and the Form D.R. 01 information sheet) or the Clerk will reject the filing (Local R. 8.01(A)).
How much is the filing deposit in Miami County?: Miami County does not publish a flat divorce/dissolution/legal-separation deposit schedule online; the Clerk of Courts sets the deposit and collects it through the e-file system. Confirm the current amount before filing at (937) 440-6046. If you cannot afford it, file an Affidavit of Indigency to ask the court to waive the deposit.
