Why Union County is different

Divorce vs. dissolution deposits

The Union County divorce deposit is $450 without minor children and $560 with minor children; the dissolution deposit is $375 / $400 and is paid before the final entry. An Affidavit of Indigency (fee waiver) is available. Confirm current amounts with the Clerk at (937) 645-3015. (Union base-hub FAQ: union-divorce-fee / union-dissolution-fee)

Co-parenting class — file within 90 days

Parents with minor children must complete Union's online co-parenting class ($49.99 per parent, about 4 hours) and file the certificate before the final hearing. In a dissolution, the case is dismissed if the certificate is not filed within 90 days. (Union base-hub FAQ: union-coparenting-class)

Hearings on temporary orders

Union holds a hearing on every temporary-order motion rather than deciding on affidavits alone, and exclusive use of the home is never granted without the other side being heard. For immediate protection, a domestic violence protection order (no filing fee; same-day ex parte; full hearing within 7–10 days) is the faster path. (Union base-hub FAQ: union-temp-orders-hearing / union-dvcpo)

Can I file Union County family law forms online?

How long does a divorce or dissolution take in Union County?

It depends on the path.
