My cousins divorced about 10 years ago. They have two daughters. One is 14 the other is 15. Their mother moved to NC about 7 years ago while the father remained in PA. The daughters lived with their father in PA until about 6 months ago, when the 15 year old moved with her mom to NC. The 14 year old stayed with her dad in PA. The 15 year old has been there about 6 months. Her grades fell and she lost a lot of weight. She was supposed to start school on August 25, 2008, but she isn't in school yet and it is now September 15, 2008. Her father is concerned that she would be better off back in PA living with him. Also, there was no agreement set about where the children would live or whom the children will live with. The daughter in NC is also living where there are a lot of drugs and her mother has no job. What type of legal action can their father take to insure that the 15 year old daughter can be bought back to PA, in safe environment, where she can go to school like she is supposed to?
