My dad married a thailand national in thailand but she did not apply successfully for a visa to live here in the uk with my dad. They have been marrried approx 4 years. My dad has made a will and has not included his wife in it. They have never lived together but he has visited his wife twice a year in Thailand. They are not divorced but he has decided that he will not be travelling to Thailand to see her again.Does she have rights to any of his estate when he dies ?
