It can be very confusing as to which court is the proper court to file a motion for alteration of parental rights and responsibilities. Do I file in the Domestic Relations Court? Or, do I file in the Juvenile Court? How are they different? It seems that they both handle child custody issues in Ohio, so which is the right one? Well, the answer is a simple one. If the parents were married and divorced, then the Domestic relations Court will handle all post-decree motions, including those related to child custody, child support and spousal support. However, if the parents were never married, then any original custody determination was made in the Juvenile Court and that Court would handle all subsequent motions related to child custody. Basically, go back to the Court where the original determination was made. If you cannot remember which Court or find your papers, then simply apply the general rule.
If you have never been married to the other parent, and there has never been a Court Order determining child custody, then you would need to file in the Juvenile Court initially.
In Sum: always file in the court that originally issued any order respecting child custody. If there has never been a Court Order respecting child custody and you are not married to the other parent, then file in the Juvenile Court. If you are married but have lived a part for several years and you want a custody determination, then look to the Domestic Relations Court.
