State ex rel. Gray v. Kimbler, 2022 Ohio 3937

David Gray and Kelly Motta divorced in 2015; their separation agreement was incorporated into the Medina County domestic-relations divorce decree.
Motta died in 2018; Gray presented a creditor’s claim to her estate, which was rejected, and Gray then sued the estate in the Medina County Court of Common Pleas (general division).
The estate filed a counterclaim alleging Gray breached the separation agreement; the general-division judge, Joyce Kimbler, presided and resolved cross-motions for summary judgment, awarding Gray a portion and granting partial summary judgment to the estate on other claims.
Gray moved to prohibit further proceedings in the general division, arguing R.C. 2301.03(U) gives exclusive jurisdiction over postdecree divorce matters to the domestic-relations division and therefore the general division patently and unambiguously lacked jurisdiction.
The Ninth District denied the writ, finding no patent and unambiguous lack of jurisdiction and that Gray had an adequate remedy by appeal; the Ohio Supreme Court affirmed.

Issue	Plaintiff's Argument (Gray)	Defendant's Argument (Judge/Estate)	Held
Whether R.C. 2301.03(U) divests the common-pleas general division of subject-matter jurisdiction over postdecree domestic-relations matters	R.C. 2301.03(U) assigns all postdecree matters to the domestic-relations division, so the general division lacks jurisdiction	R.C. 2301.03(U) assigns cases to the domestic-relations judge but does not grant exclusive jurisdiction; general-division judges retain the same powers and jurisdiction and may hear such matters in special circumstances	Court held R.C. 2301.03(U) does not patently and unambiguously divest the general division of jurisdiction; statute does not speak in exclusivity
Whether Gray lacks an adequate legal remedy so as to justify extraordinary relief by prohibition	Argued that appeal is inadequate because of irreparable harms (reputational harm, forced sale of property)	Ordinary appeal is available and sufficient to challenge jurisdictional exercise; generalized litigation harms do not render appeal inadequate	Court held Gray has an adequate remedy by direct appeal; harms alleged do not justify bypassing appeal requirement
