Forms & Filing Packets

Annulment with minor children

If children were born during the marriage, parentage and support must be addressed even when the marriage is voided.

How to File Annulment in Montgomery County

  1. Confirm you have a statutory ground. Annulment requires an R.C. 3105.31 ground such as bigamy, fraud, underage marriage, or incapacity — and most have short time limits.
  2. Prepare the Complaint for Annulment. Use the Montgomery County annulment assistant at mcdrc.ohiolegalhelp.org and add the Affidavit of Financial Disclosure.
  3. Address children if applicable. If there are children, include the Parenting Proceeding Affidavit and child-support worksheet — parentage and support still apply.
  4. File at the DR Court. Self-represented parties review through the Compliance Office; pay the ~$300 deposit at the Clerk, 41 N. Perry Street.

Montgomery County Practice Notes

  • Annulment grounds are narrow. Ohio annulments require a specific R.C. 3105.31 ground — bigamy, underage marriage without consent, fraud, force, mental incapacity, or a marriage never consummated. Most grounds carry short deadlines. If none applies, file for divorce or dissolution.
  • Children are still protected. Children born during a voided marriage remain the legal children of both parents. Parentage, custody, and support are still addressed even though the marriage is annulled.
  • Best-interest standard governs. R.C. 3109.04(F)(1) lists 10+ factors: each parent's wishes, the child's wishes (when of sufficient age), the child's interaction with parents/siblings, adjustment to home/school/community, mental and physical health of all involved, the parent more likely to facilitate court-approved parenting time, child support compliance, criminal history, residence outside Ohio, and any history of abuse.

What are the residency requirements to file in Montgomery County?
For divorce, legal separation, or annulment, you or your spouse must have been an Ohio resident for at least 6 months immediately before filing, and a Montgomery County resident for at least 90 days. For dissolution, only the 6-month Ohio residency applies — there is no separate Montgomery County residency requirement. For Juvenile Court cases (paternity, never-married custody, child support), Ohio must be the children's 'home state' under the UCCJEA, generally meaning they have lived in Ohio for the last 6 months.
