My question involves paternity law for the State of: Missouri
I have been divorced for 3 years and recently my ex wife has threatened to take my son away from me. She says that she doesn't think I am the biological father. My son is 7-1/2 years old. We have joint legal and joint physical custody. I am the residential parent. At this point I don't care if he is my DNA or not, he is MY son and losing him would destroy me. His mother is using him as a weapon and I'm scared of what this will do to him if she moves forward with her threats. She said she can get a court-ordered paternity test and strip me of my rights. Is this really possible after so many years?
Some additional facts:
My ex can't hold a job, has had at least 1 DUI and is living out of a bedroom with friends. To my knowledge her transportation is in her current boyfriends name. She has a track record as being very irresponsible. The judge even refused to name her as the Residential parent in our divorce. Does any of this lean in my favor?
If I am shown NOT to be the biological father, what rights do I still have?
