The issue this case presented for the Ohio Supreme Court centered on whether whether oil-and-gas land professionals, who help obtain oil-and-gas leases for oil-and-gas-development companies, must be licensed real-estate brokers when they engage in the activities described in R.C. 4735.01(A) with respect to oil-and-gas leases. Specifically, the Court addressed address whether R.C. 4735.21 precluded a person not a licensed real-estate broker from bringing a cause of action to recover compensation allegedly owed for negotiating oil-and-gas leases. The Court concluded the plain language of R.C. 4735.01 did not exclude oil-and-gas land professionals or oil-and-gas leases from the relevant definitions set forth in the statute; appellants Thomas Dundics and his company, IBIS Land Group, Ltd., engaged in activities that required a real-estate-broker’s license and were precluded from bringing a cause of action to recover compensation for those activities.
