What actions need to be taken if you would like to try to take away the rights of your childs other parent?:
Proof that the other parent is a FELON or is commiting FELONIES right now.. You had a child with this person and you are going to have to SHARE parenting time with this person, unless you can prove in some way that this person is an unfit parent or is in the process of commiting crimes of some kind.. 

Truthfully, this person DESERVES to have parenting time and influence in the course that this child's life is going..
