I was married in Costa Rica 12 years ago. Separated for 10 years. I live in the United States, she lives in Costa Rica. I filed for divorce here in New York and mailed the divorce papers for her to sign in front on a notary in the US Embassy of Costa Rica(I was told this is how she needed to sign). She is refusing to sign because she believes the divorce won't be valid in Costa Rica. Is this true? Will our divorce be valid in the USA and Costa Rica or do we also need to file for divorce in Costa Rica?
