Montgomery County, Ohio · Dayton

In Ohio, 'custody' means the allocation of parental rights and responsibilities. In Montgomery County, where you file depends on whether the parents were married: the Domestic Relations Court at 301 West Third Street for married or divorcing parents, the Juvenile Court at 380 West Second Street for never-married parents. The court decides using the R.C. 3109.04(F) best-interest factors.

How do I file for custody in Montgomery County, Ohio?

If you and the other parent were married, custody is decided inside your divorce or dissolution at the Montgomery County DR Court, 301 West Third Street, Dayton — file the Parenting Proceeding Affidavit, Standard Order of Parenting Time, and Ohio child-support worksheet with your packet. If you were never married, file the Allocation of Parental Rights Packet at the Montgomery County Juvenile Court, 380 West Second Street. The court applies the R.C. 3109.04(F) best-interest factors, and both parents must complete the parenting class before the final hearing.

Hire Gavvl Law for your Montgomery County custody case

Custody in Dayton runs on two tracks — Domestic Relations at 301 West Third Street for married or divorcing parents, Juvenile Court at 380 West Second Street for parents who never married — and each has its own fee schedule and procedures. Gavvl Law files in the correct courthouse with a parenting plan built for Montgomery's own standards, as a flat-fee filing service or full representation through a contested custody hearing.

A plan measured against the Standard Order. Montgomery's Standard Order of Parenting Time assumes roughly 90 overnights a year for the non-residential parent, and judges evaluate proposals against that baseline. Whether you want the Standard Order or a schedule tailored to shift work and school routines, we draft it so the court sees a workable plan, not a wish list.
Eyes open on investigation and GAL costs. Contested Montgomery custody cases can trigger a Family Relations custody investigation (a $1,000 fee) and a Guardian ad Litem whose fees are capped at $2,000. We tell you when those steps are likely, what they cost, and how to present your household before an investigator ever visits.
Jurisdiction confirmed before you spend a dollar. Ohio must be your children's home state — six months of residence under the UCCJEA — before a Dayton court can decide custody. We verify jurisdiction and pick the right division first, because the fastest way to lose months is filing a custody case the court cannot hear.

Montgomery expects parents in custody cases to complete "Helping Children Succeed After Divorce," and self-represented DR paperwork routes through the Compliance Office before it's accepted. We handle the seminar logistics and file attorney-grade paperwork directly, so your Dayton custody case spends its time on parenting issues instead of process.

Flat-fee options

Flat-fee limited scope: we draft and file the custody complaint or motion; you appear at any hearing.

Establish custody: $1,250
Modify custody: $1,450

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.

How to File Custody in Montgomery County

Pick the right court — DR or Juvenile. Married/divorcing parents → Montgomery County DR Court at 301 West Third Street. Never-married parents → Montgomery County Juvenile Court at 380 West Second Street (a separate building). Grandparent/non-parent custody is always Juvenile.
Confirm Ohio is the children's home state under the UCCJEA. The children must have lived in Ohio for the prior 6 months. The Parenting Proceeding Affidavit is how you swear to those facts.
Assemble the packet for your court. DR: Parenting Proceeding Affidavit + Standard Order of Parenting Time + child-support worksheet + health-insurance affidavit. Juvenile: the Allocation of Parental Rights Packet + UCCJEA affidavit + IV-D Application.
Complete the parenting class and file. Both parents complete 'Helping Children Succeed After Divorce' and file proof. Self-represented DR parties review through the Compliance Office; Juvenile filers can use Citizen Services.

Montgomery County Practice Notes

Standard parenting time and 90 overnights. Montgomery's Standard Order of Parenting Time (effective January 1, 2026) controls unless the parents agree to or the court orders a different schedule. It assumes 90 overnights for the non-residential parent for child-support calculation purposes.
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.
Guardian ad Litem in contested cases. In a contested custody case, the court can appoint a Guardian ad Litem — a court-appointed attorney — to investigate and recommend a parenting plan in the child's best interest. The GAL does not represent the child's wishes; the GAL represents what is best for the child. GAL fees are typically allocated between the parents.

Frequently Asked Questions

Do I file in Domestic Relations or Juvenile Court in Montgomery County?: If you are married to the other parent (or were married when the children were born), custody, parenting time, and child support travel with the divorce, dissolution, legal separation, or annulment at the Domestic Relations Court, 301 W. Third Street. If you were never married, paternity and custody go to the Montgomery County Juvenile Court at 380 W. Second Street — a separate building in downtown Dayton. Grandparent and non-parent custody is always Juvenile.
Is the parenting class required in Montgomery County?: Yes. 'Helping Children Succeed After Divorce' is mandatory for all parties with minor children under Mont. D.R. Rule 5.5. The 3-hour class is held through Sinclair Community College. Register at go.mcohio.org or call the Parent Education Department at (937) 225-5412. File proof of completion before the final hearing.
When does Montgomery County appoint a Guardian ad Litem?: In contested custody cases the court can appoint a Guardian ad Litem, whose fees are capped at $2,000 unless the court approves more (Mont. D.R. Rule 5.2). The court can also order a custody investigation through the Family Relations Department for a $1,000 fee, (937) 225-4191. The GAL investigates and files a written report before the final hearing.
What does it mean for Ohio to be my child's 'home state' under the UCCJEA?: Under the UCCJEA (R.C. 3127), Ohio is the children's home state when they have lived in Ohio with a parent for at least 6 consecutive months immediately before the filing. If the children recently moved, the prior state may still have jurisdiction. Ohio courts can also decline jurisdiction as an inconvenient forum under R.C. 3127.21 even when home-state requirements are met.
