There is a new Belmont County case, which speaks extensively about the 1989 ODMA, automatic vesting, and the nature of the vested right that it gave surface owners.

It came out last October 2013:

Automatic Vesting

The 1989 version of the Ohio Dormant Mineral Act vests the surface owner with ownership in severed mineral interests without the need for any notice, recordation of any document, assertion of any claim or filing of any action.

Nature of a Vested Right

"A 'vested right' is a right that so completely and definitely belongs to a person that it cannot be impaired or taken away without the person's consent."
