I live in CT. My ex wife has made a habit of making sure I hear about outright lies she spreads from time to time. So I don't know if I believe it, but she has been telling people I am not our child's father. I have joint legal custody of the child. Can I have a DNA sample taken for the purpose of establishing paternity without my ex wife's knowledge? I want to know for sure before starting what would surely be a very ugly situation.
