My sister is 18, and currently resides in the state of Washington. Her son was born in Florida and she was never married to the father of her child, but they were "together" at the time. She moved to Washington to be near our mom who is sick, and of course took her son with her. She has been providing a safe and secure home for him and is in the process of getting her diploma. She wanted to come to Florida on a visit, but has been warned by friends that if she does, the baby's father is going to take him from her. I told her that I was pretty sure that because they were never married, and he has never petitioned for any type of guardianship or custody, that he would have to do all of this first, and then prove why he thinks the baby would be better off with him before he could legally take the child. Am I correct with this statement, and where can I find the "proof" in writing to put her mind at ease? Thank you for your time.
