You have not provided any detail whatsoever to enable anyone to make an honest attempt at an answer to your query, either about the nature of the abuse or what actions were taken by the authorities.
Here are some facts that may result in the abuse not being taken seriously:
Statistics on child abuse are controversial because there is so much abuse that is never reported. Statistics are human creations, can be easily manipulated to suit the user and often are. All statistics and reports of prevalence of child abuse are disputed by some experts. Huge numbers of children who are abused are never in a position to have the abuse reported. It is often kept secret by the family for fear of publicity. It is often kept secret by the child for fear of harm if they report it. Lastly, only recently has child abuse come to be viewed as a major social problem at all.
Child abuse occurs across all cultural, gender, racial, economic and social lines. It is committed most often by the caretaker of the child. People who abuse their children lack the necessary abilities needed to parent properly, to nurture and to form a consistent, stable relationship with their child. Children with special needs are sometimes at more risk because of the stress of parenting the child and the lack of understanding by the parent that the child's behavior is caused by their disability.
People who abuse are frequently self-centered, lack coping skills and have little understanding of normal child development. They often have unreasonably high expectations of what constitutes normal behavior in a child. They have anger management issues. They are people who put other things first ahead of their child's needs: work, money, sleep, their own entertainment, their partner, their friends, their own needs. They frequently have substance abuse problems.
If the father has visitation rights and the mother refuses to allow the father those rights, then the father can sue the mother in a civil contempt proceeding. If she doesn't have a good reason for disallowing the visitation then she can be held in contempt of court. There are various remedies including giving the father more visitation to make up for the visitation that was disallowed by the mother or even giving the father custody, but usually, the judge will just order the mother to allow the visits. His paying or not paying child support has nothing to do with whether or not he gets visitation (i.e. he gets visitation regardless of whether or not he is current with child support).
I don't believe so.
No, a stepfather will not have visitation rights to his stepson after a divorce. The mother can always allow the stepfather to visit if she wants.
He essentially give up everything. The child is no longer his legally. He has no responsibilities toward the child and has no visitation rights.
Once the father's paternity has been established in court she has to be able to prove he is unfit or the court will allow him his rights. If she refuses even though there is a visitation order she would be in contempt of a court order and could eventually lose custody if she continues to interfere with his visits.
If there's a court order, than yes.
As many rights as the mother wishes to allow until the father protects himself with court ordered visitation and decision making rights. In some states, the father may have certain intrinsic rights, but you would need to provide where you reside and the state (or country if outside the USA) where the child legally resides.
He doesn't. Only the courts can award/enforce visitation.
You can go back to court and request that the visitation order be modified to better suit the situation and allow the children time with their father.
Many states allow stepparent visitation rights
yes he can, provided they have filed a settlement agreement with the court in the county in which you live which gives your father rights of visitation or parenting time. If your mom does not allow your father to exercise his rights of visitation with you, she can be held in contempt of court for witholding you from him. If you do not wish to spend time with your father, it's best to explain to him why and usually you can work out a reasonable 'break time' until you want to spend time with him again.
No. There is no provision in North Dakota state laws to allow visitation with an ex-step-parent. That person would have no legal standing.
