Which of the following could render a recorded deed voidable in Ohio?

A deed that is written over a blank sheet with a signature could be rendered voidable in Ohio due to the potential ambiguity regarding its authenticity and the completeness of its contents. In the case of a blank sheet, while the signature may indicate an intention to transfer property, the lack of specified details—such as the names of the parties involved, a legal description of the property, and the terms of the conveyance—could lead to disputes regarding the deed's enforceability. This ambiguity allows parties to challenge the deed's validity in a court of law, rendering it voidable at the behest of a party who can demonstrate that the deed does not reflect their true intent.

In contrast, the other scenarios involve more definitive issues of legality or execution, such as the first choice regarding a torn piece of paper, which may affect the recordability rather than the validity. The third choice about the lack of a notary's signature pertains to a requirement for acknowledgment rather than the deed's inherent validity, while the last scenario, which involves a verbal agreement, does not meet the statutory requirements for property conveyance, thereby voiding it outright rather than making it voidable.
