I am helping a birthsister search for her sister given up for adoption in Chile...she believes her sister was adopted into the United States, Does anyone have any idea about what the adoptee's and birthparents rights are in Chile? I cant seem to find out much about this. The sister doesnt have very much information, and is unsure on the month and date of birth. Can anyone give me some guidence so I can better help her???
