If you and she have "joint legal custody", the she must, by law, notify you and gain your acceptance, when a move affecting your minor child's residency is about to take place. What proof is there that the "other man" is a criminal? If the man has served his time, then he is not presently a criminal.
If you mean, the child's mother (ex-wife) has custody, the child's father (ex-husband) is obligated or potentially obligated for support.
He has two daughters with ex-wife Sara, and a son from his first ex-wife
No, it is not wise for the new girlfriend and ex wife to be friends and the ex wife should move on. If children are involved then the ex husband and ex wife should be dealing with this.
yes
Your girlfriend is not responsible for other women's children.See links below
You can ask the court to do so, but you are not likely to be successful as long as your ex-wife has legal custody and your child has a hunting license.
No....
Yes of course if he has custody.
no unless he can not support the child
For your sake, I hope she's willing to repeat that story to the judge.
Your current wife is not responsible for your children by your ex-wife.
no
