Final answer:
Behan's interest to the described real property, upon Behan's death, would pass to his wife as they owned the property jointly.
Step-by-step explanation:
Behan's interest to the described real property, upon Behan's death, would pass to his wife, assuming she did not intentionally bring about his death. As tenants by the entirety, both Behan and his wife hold equal and undivided interests in the property. This means that upon Behan's death, his interest would automatically transfer to his wife, as they owned the property jointly. The estate would not escheat to the State of Michigan, as escheat typically occurs when there is no living heir or beneficiary to inherit the property.
