My best attempt to summarize the situation; Ohio property purchased as JTWROS by A, B, and C. A and B are married. C is adult child of A and B. Unfortunately, A suddenly passes, not leaving a will. Considering Ohio dower rights, what respective percentages of ownership do B and C now hold in the property?
Each party had a 33.3% interest in the real estate. When A dies, B gets A's share so has a 66.6% interest. Per Ohio intestate succession law and given that C is the child of A and B, B gets 100% of everything that is A's, see ORC 2105.06(B).
