Yi Seul Buys a House from Jackson but Does Not

Essay

Yi Seul buys a house from Jackson but does not record her ownership interest. Later, Jackson dishonestly sells the same house to Eva who had checked ownership at the courthouse but saw no mention of Yi Seul. After she paid Jackson, Eva recorded her property interest at the courthouse. Eva, who thought that Yi Seul was renting the house from Jackson, then wrote to Yi Seul asking her to move. Who is entitled to the house? What do you believe ethically should be done, assuming Jackson cannot be found?
