can a house that was suppose to b sold 20 years ago now be forced to sell after a new wife and death of husband. can the x come forward 20 years later to claim 1/2 of something she never enforced for 20 years? she never filed a lein, never filed papers. nothing.. now that he died and I was married to the man for 18 years, now she shows up out of the blue and wants half of the house I can not see why all of a sudden she cares. .This is my home due to the fact that she never claimed it. tell me my rights please,Is there not a statute of limitations on such a manner.
