Butler County, Ohio · Hamilton

In Ohio, 'custody' means the allocation of parental rights and responsibilities. In Butler County, where you file depends on whether the parents were married. Married or divorcing parents file at the Domestic Relations Court, 315 High Street; never-married parents file at the Butler County Juvenile Justice Center, 280 N. Fair Ave. The court decides using the R.C. 3109.04(F) best-interest factors.

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

If you and the other parent were married, custody and parenting time are decided inside your divorce or dissolution at the Domestic Relations Court, 315 High Street, Hamilton — or, if you are married and living separately, by filing a DR727 Complaint for Support and/or Custody. If you were never married, file a Complaint for Custody at the Butler County Juvenile Justice Center, 280 N. Fair Ave., where the fee is $165 plus $50 clerk service. File the parenting affidavit and IV-D application, and complete parenting education before the final hearing.

Put a flat-fee custody attorney on your Butler County case

Where a Butler County custody case belongs depends on the marriage: married or divorcing parents allocate parental rights at Domestic Relations on 315 High Street, while never-married parents file a Complaint for Custody at the Juvenile Justice Center, 280 N. Fair Avenue, where the fee is $165 plus $50 clerk service. Gavvl Law files the DR727 for married parents living separately or the Juvenile complaint for unmarried parents, prepares the DR616 parenting affidavit and DR624 guideline worksheet, and offers a flat fee with payment plans.

Right building, right complaint. Filing custody in the wrong court restarts the clock. We route married parents living separately to Domestic Relations on the DR727 Complaint for Support and/or Custody, and never-married parents to the Juvenile Justice Center on 280 N. Fair Avenue, so your case opens in the venue that can actually decide it.
The parenting affidavit and worksheet done right. Butler County wants the DR616 parenting and UCCJEA affidavit confirming Ohio is the children's home state, plus the DR624 sole or shared guideline worksheet. We complete both accurately the first time so the court is not sending paperwork back before it reaches the merits.
Built around the best-interest factors. Custody in Butler County turns on the R.C. 3109.04(F) best-interest factors, not on who files first. We frame your evidence — the children's adjustment, each parent's involvement, and willingness to support the other's parenting time — to those specific factors.

Because we file in both the Domestic Relations Court and the Juvenile Justice Center, we can tell you up front which venue your facts point to and what parenting-education and IV-D paperwork each requires before the final hearing. That saves a wasted filing and keeps a never-married case moving at 280 N. Fair Avenue.

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 Butler County

Pick the right court — DR or Juvenile. Married/divorcing parents file at the Domestic Relations Court, 315 High Street. Never-married parents file at the Juvenile Justice Center, 280 N. Fair Ave. Grandparent/non-parent custody is always Juvenile.
Confirm Ohio is the children's home state. The children must have lived in Ohio for the prior 6 months under the UCCJEA. The DR616 parenting affidavit is how you swear to those facts.
Assemble the packet for your court. DR: DR727 complaint (or custody inside a divorce) plus DR616 affidavit and child-support worksheets. Juvenile: Complaint for Custody (one per child) plus parenting affidavit and IV-D application.
Submit, file, and complete parenting education. Route DR packets through E-Submission to Case Management; file Juvenile complaints at 280 N. Fair Ave. Complete the required parenting class before the final hearing.

Butler County Practice Notes

One child per filing in Juvenile Court. Butler County Juvenile Court requires a separate complaint for each child (Juvenile Local Rule 3.05), plus the Face Sheet (Appendix I) and relief codes (Appendix J) in the caption, and a IV-D application for support, custody, or visitation.
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.
UCCJEA jurisdiction. Ohio courts may exercise custody jurisdiction only when Ohio is the child's home state under R.C. 3127. The Parenting Proceeding Affidavit (R.C. 3127.23) is the sworn vehicle for establishing those facts. If the child recently moved from another state, the prior state's court may retain jurisdiction.

Frequently Asked Questions

Do I file in Domestic Relations or the Juvenile Justice Center?: If you are married to the other parent (or were married when the children were born), custody, parenting time, and child support travel with your divorce, dissolution, legal separation, or annulment at the Domestic Relations Court, 315 High Street, Hamilton. If you were never married, paternity and custody go to the Butler County Juvenile Justice Center at 280 N. Fair Ave., a separate building. Grandparent and non-parent custody is always Juvenile.
What are the residency requirements to file in Butler County?: For divorce, legal separation, or annulment, you or your spouse must have lived in Ohio for at least 6 months before filing and in Butler County for at least 90 days. For dissolution, only the 6-month Ohio residency applies — there is no separate Butler County residency requirement. For never-married custody, paternity, or support filed at the Juvenile Justice Center, Ohio must be the children's 'home state' under the UCCJEA, which generally means they have lived in Ohio for the last 6 months.
How much does it cost to file in Butler County?: Domestic Relations filing deposits are set by the Butler County Clerk of Courts and posted at clerkofcourts.bcohio.gov; you pay them after the Case Management Office approves your packet. Juvenile Justice Center filings are $165 plus $50 clerk service for a custody, support, allocation, or visitation complaint ($165 plus service for paternity; $45 for a relocation notice). If you cannot pay, file Form DR824 to proceed in forma pauperis at DR, or an indigency affidavit at Juvenile.
When does Butler County appoint a Guardian ad Litem?: In contested custody cases the court can appoint a Guardian ad Litem under DR Local Rule 43 to investigate and report on the children's best interest. Butler County GALs are paid $125 per hour with a $1,200 deposit at DR (up to $1,250 per party at the Juvenile Justice Center). The GAL's written report is due at least 7 days before trial.
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.
Is the parenting class required in Butler County?: Yes. Both parents in any Butler County divorce or dissolution with minor children must complete 'Helping Families Succeed During Divorce,' a 4-hour online Zoom program run by the Forensic Evaluation Services Center (FESC, (513) 869-4014). Register within 15 days of filing using Form DR628 and finish before the final hearing. Spouses cannot attend the same session, and you need your DR case number to schedule. A Spanish-language version runs about once a month.
