My father was a naturalized citizen. He passed away in Dec of 2009 there is a woman claiming to be his wife. She claims they got married in dec of 2001 in Colombia, South America she has a "marriage Certificate" by a notary in Colombia. The same notary that "preformed wedding" Also signed its authentication in 2010. She is now trying to be appointed as his executor of his estate. there was no will. She is unable to come to the U.S. however she has an american lawyer. She lived with my dad for three years in the United States They both filed income taxes as single individuals. My dad had property and had signed affidavits stating he was not married during the time they lived together. Is there any law or way for me to fight this. Immagration denied her request to change status. I have audio taped conversations of this woman talking to her boyfriend while residing with my father stating she was trying to marry my father for a visa and for money. Again is there any law that may help me?
