Can an adopted child inherit from a biological parent who dies intestate if the adopted child was adopted by the blood relatives?

The relevant issues include the language in the adoption order and the laws in effect at the time the biological parent died.  Whether or not the adopted child knows of the adoption or maintains a relationship with the natural parent is not relevant. Ohio Revised Code 3107.15 states "the adopted person [after the final decree of adoption] is a stranger to the adopted person’s former relatives for all purposes including inheritance".  This means that typically an adopted child is not permitted to inherit from a natural parent who dies intestate (without a will) unless the adopted child is specifically referenced in a Will or non-probate asset (e.g., life insurance or other beneficiary designation).
