Yes, everyone here gets your point but you are not getting theirs. It does not matter if he went out of his way to find this information. The point is that endangering a child (whether or not it is the child that you share with this person) is a reflection on your character and can help him to gain additional visitation with the child. Even though he is going for visitation and not full custody, that information is pertinant to the case. I understand that you may be upset that this information was discovered by him but it is public record. Also, any information concerning an individual that involves child endangerment can be brought into any case involving that individual and a child (doesn't matter if it is the child involved in the situation that was deemed to be child endangerment). If you found out your child's father had endangered another child I do not believe for one second that you would not bring it up in court against him.
