My Daughter Found me on myspace after about 15 years of us not seeing each other. I added her to my Yahoo E-MAIL and she is using her Step Dads last name. Is There a way for me to find out if he Adopted her without my Permission?

Ask her, call up your ex and ask her. *** I seldom add person notes but if you did not find her or talk to her for 15 years, do you really care. Most likely if they could not find you, they posted notice of hearing in a newspaper and you did not show up.
