Ohio has no presumption for shared parenting or for equal parenting time. A shared parenting order can only issue if a parent files a shared parenting plan and the court finds the plan is in the child's best interest — and the § 3109.04(F)(2) factors, which focus on whether the parents can actually cooperate and make decisions jointly, are the gate. If you and the other parent cannot communicate, Ohio is unlikely to order shared parenting no matter how involved you both are. The default outcome is one residential parent and legal custodian, with parenting time for the other.
Use the state’s own words
Ohio deliberately avoids the word "custody" in the ordinary case. The statute speaks of the "allocation of parental rights and responsibilities for the care of children." One parent is designated "the residential parent and legal custodian"; the other has "parenting time." Where parents share, the court issues a "shared parenting order" based on a filed "shared parenting plan," and both parents are then "residential parent and legal custodian." If you write "joint custody" on an Ohio filing you are using a term the statute does not use — say "shared parenting."

Decisions against where the child lives
Ohio does not split legal from physical the way most states do. Under ORC § 3109.04, the court either designates one parent as "residential parent and legal custodian" — a single combined role covering both decisions and residence — or issues a shared parenting order under a plan that must address "physical living arrangements, child support obligations, provision for the children's medical and dental care, school placement, and the parent with which the children will be physically located during legal holidays, school holidays, and other days of special importance." Note that a shared parenting order is not automatically an equal-time order: it allocates the role of residential parent to both, while the plan itself sets the actual schedule. Even where one parent is the residential parent, ORC § 3109.051(H)(1) entitles the other parent to school and other records "under the same terms and conditions under which access is provided to the residential parent," unless the court finds that would not be in the child's best interest and makes written findings.
What the judge must weigh
Under § 3109.04(F)(1) the court considers the wishes of the child's parents; the wishes and concerns of the child, if the child has been interviewed; the child's interaction and interrelationship with parents, siblings and others who may significantly affect the child's best interest; the child's adjustment to home, school and community; the mental and physical health of all persons involved; the parent more likely to honor and facilitate court-approved parenting time; whether either parent has failed to make all child support payments; whether either parent or a household member has been convicted of or pleaded guilty to an offense involving a victim who was a child and resulted in a child being abused or neglected; whether either parent has been convicted of or pleaded guilty to "a violation of section 2919.25 of the Revised Code or a sexually oriented offense involving a victim who at the time of the commission of the offense was a member of the family or household"; whether either parent has continuously and willfully denied the other parent's right to parenting time; and whether either parent has established or plans to establish a residence outside Ohio. For shared parenting specifically, § 3109.04(F)(2) adds: "The ability of the parents to cooperate and make decisions jointly"; the ability of each parent to encourage the sharing of love, affection and contact with the other parent; any history of, or potential for, child abuse, spouse abuse, other domestic violence, or parental kidnapping; the geographic proximity of the parents to each other; and the recommendation of the guardian ad litem, if one has been appointed.
What the child wants
Ohio sets no age, and uses a reasoning-ability test instead. Under § 3109.04(B)(1) the court "in its discretion, may and, upon the request of either party, shall interview in chambers any or all of the involved children regarding their wishes and concerns." So either parent can compel an in-chambers interview. Then § 3109.04(B)(2)(b) requires the judge to "first… determine the reasoning ability of the child." If the child lacks sufficient reasoning ability to express their wishes, the court does not take them into account. If the child has sufficient reasoning ability, the court then decides whether "because of special circumstances, it would not be in the best interest of the child" to determine the child's wishes — and if so, it must enter written findings of fact and opinion. Two more Ohio-specific rules: under § 3109.04(B)(2)(a), if the court interviews the child, it "in its discretion, may and, upon the motion of either parent, shall appoint a guardian ad litem for the child" — so either parent can force a guardian ad litem simply by moving for one once an interview happens. And Ohio prohibits written statements or affidavits from children; the input comes through the in-chambers interview, not a letter.
Where there has been violence or abuse
Ohio handles this through required considerations rather than a presumption. Section 3109.04(F)(1) requires the court to consider whether either parent or a household member has been convicted of or pleaded guilty to an offense involving a child victim that resulted in a child being abused or neglected, and whether either parent has been convicted of or pleaded guilty to "a violation of section 2919.25 of the Revised Code" — Ohio's domestic violence offense — "or a sexually oriented offense involving a victim who at the time of the commission of the offense was a member of the family or household that is the subject of the proceeding." For shared parenting, § 3109.04(F)(2) separately requires the court to weigh "any history of, or potential for, child abuse, spouse abuse, other domestic violence, or parental kidnapping by either parent." Ohio also builds protection into the relocation notice system: under § 3109.051(G)(2)–(4), where a parent with parenting time has a domestic violence conviction, an offense against a household member causing physical harm, or has been determined to be the perpetrator of abuse underlying a child abuse adjudication, the court must order that they not receive a copy of the other parent's relocation notice unless the court finds it is in the children's best interest and makes specific written findings. A residential parent can also file a motion asking that the abusive parent not receive the notice.
The paperwork and the people
The parenting plan
A shared parenting plan is required if you want shared parenting — there is no shared parenting without a filed plan. ORC § 3109.04 requires the plan to address "physical living arrangements, child support obligations, provision for the children's medical and dental care, school placement, and the parent with which the children will be physically located during legal holidays, school holidays, and other days of special importance." If neither parent files a plan, the court allocates parental rights to one parent instead. We did not find a single statewide mandatory form — Ohio's domestic relations courts operate under local rules, so get the plan format from the clerk in your county.
Mediation
No — mediation in Ohio is discretionary and is run under each court's local rules, with a required domestic violence screen. ORC § 3109.052(A): where parents "do not agree upon an appropriate allocation of parental rights and responsibilities… or do not agree upon a specific schedule of parenting time," the court "may order the parents to mediate their differences on those matters in accordance with mediation procedures adopted by the court by local rule." Before ordering it, the court "shall consider" whether either parent has been convicted of or pleaded guilty to domestic violence under § 2919.25 involving a family or household member, or another offense against a household member that caused physical harm, or has been determined to be the perpetrator of abuse underlying a child abuse adjudication. Because the procedures are local, ask your county's domestic relations court what its mediation rule requires. https://codes.ohio.gov/ohio-revised-code/section-3109.052
If the court appoints someone to look into it
ORC § 3109.04(B)(2)(a) is the provision most parents will use: where the court interviews the child, it "in its discretion, may and, upon the motion of either parent, shall appoint a guardian ad litem for the child." The guardian ad litem's recommendation is then an express factor in the shared parenting analysis under § 3109.04(F)(2). We could not confirm from the statute how guardian ad litem fees are allocated between the parents — Ohio handles this through the Rules of Superintendence and local court rules. Ask the judge to set the rate and the split at the time of appointment.
Moving away
What you must do before you move
Ohio requires notice to the court, not permission, and sets no distance trigger. ORC § 3109.051(G)(1): "If the residential parent intends to move to a residence other than the residence specified in the parenting time order or decree of the court, the parent shall file a notice of intent to relocate with the court that issued the order or decree." The court then sends a copy to the non-residential parent (subject to the domestic violence exceptions above), and "Upon receipt of the notice, the court, on its own motion or the motion of the parent who is not the residential parent, may schedule a hearing with notice to both parents to determine whether it is in the best interest of the child to revise the parenting time schedule for the child." Read that carefully: any move to a new address triggers the filing requirement, even across town; there is no mileage threshold and no consent requirement; and what is at stake at the hearing is the parenting time schedule. https://codes.ohio.gov/ohio-revised-code/section-3109.051

Changing the order
ORC § 3109.04(E)(1)(a): "The court shall not modify a prior decree allocating parental rights and responsibilities for the care of children unless it finds, based on facts that have arisen since the prior decree or that were unknown to the court at the time of the prior decree, that a change has occurred in the circumstances of the child, the child's residential parent, or either of the parents subject to a shared parenting decree, and that the modification is necessary to serve the best interest of the child." Note that under a shared parenting decree the relevant change can be in either parent's circumstances, whereas in a sole-residential-parent case the change must be in the child's or the residential parent's circumstances — not the non-residential parent's. There is no statutory waiting period.
If you were never married
Ohio has one of the sharpest rules in the country, and unmarried fathers are frequently caught out by it. ORC § 3109.042(A): "An unmarried female who gives birth to a child is the sole residential parent and legal custodian of the child until a court of competent jurisdiction issues an order designating another person as the residential parent and legal custodian." Until you go to court and get an order, the mother is the sole legal custodian — no matter that paternity has been established, that your name is on the birth certificate, or that you have been paying support. But the same subsection also levels the field once you do file: "A court designating the residential parent and legal custodian of a child described in this section shall treat the mother and father as standing upon an equality when making the designation." You are not starting from behind at the hearing; you simply have to get to the hearing. One exception, at § 3109.042(B): an unmarried mother convicted of rape or sexual battery who is declared under § 3109.501 to be the parent of a child born as a result "shall not be a residential parent and legal custodian of that child." https://codes.ohio.gov/ohio-revised-code/section-3109.042
The one that costs unmarried Ohio fathers the most: until a court issues an order, the mother is the sole residential parent and legal custodian by operation of law, even if paternity is established and you are on the birth certificate. Nothing about that is a judgment on you as a parent — and when you do file, the statute requires the court to treat you and the mother "upon an equality." File. The second surprise is a good one: either parent can require the judge to interview the child in chambers, and once that interview happens, either parent can require the court to appoint a guardian ad litem simply by filing a motion. Those are powerful levers that many Ohio parents never learn they have. Third, note that any change of address triggers a relocation notice filing — there is no minimum distance.
What we could not confirm
- We could not confirm how guardian ad litem fees are divided between parents in Ohio, or the details of your county's mediation rule, because both are set by the Rules of Superintendence and by local court rules rather than by statute. Ask the domestic relations court in your county for its local rules, and ask the judge to set the guardian ad litem's rate and the cost split at the moment of appointment rather than later.
