MY father-in-law has "given" my husband the house. He claims it would be too expensive on us to have the title and deed changed into our name. Is that true, and how do I find out how expensive? Also, I have heard, according to Oklahoma law, if something happens to my father-in-law, no matter what kind of pre-nup or will he might have, the house would go to his new wife. Is that true? Thanks for your help!
