Except as provided in section 2105.36 of the Revised Code, the following shall apply:
(A) If it is not established by clear and convincing evidence that one of two co-owners with right of survivorship survived the other co-owner by one hundred twenty hours, one-half of the property or account passes as if one co-owner had survived the other co-owner by one hundred twenty hours, and one-half of the property or account passes as if the other co-owner had survived the one co-owner by one hundred twenty hours.
(B) If there are more than two co-owners with right of survivorship and it is not established by clear and convincing evidence that at least one of the co-owners survived the others by one hundred twenty hours, the property or account passes in the proportion that one co-owner's ownership bears to the ownership of the whole number of co-owners.
