Religion, immigration, or health insurance makes divorce undesirable right now.
You may not yet meet the residency requirement for divorce but need orders in place.
You or your spouse have been an Ohio resident for 6+ months and a Montgomery County resident for 90+ days.

Montgomery County Practice Notes

You stay married. A legal separation resolves property, debt, support, and parenting without ending the marriage. Neither spouse can remarry. Either spouse can later convert to or file for divorce if they decide to end the marriage.
Same children's requirements as divorce. Cases with minor children require the Parenting Proceeding Affidavit, child-support worksheet, and completion of 'Helping Children Succeed After Divorce' before the final hearing.
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.
