If the mother does not allow the father to see their child, it is a violation of parental rights. In some cases, if this occurs without legal justification or intervention, this could lead to criminal charges for the mother. The court may also intervene and order that visitation rights be granted to the father. Depending on state laws and local regulations, other measures such as supervised visits or counseling may be required for both parties in an effort to ensure that both parents are able to provide a safe and healthy environment for their child. In extreme circumstances, custody of the child can even be transferred from one parent to another in order to protect them from harm or neglectful behavior.
No matter what happens between two parties involved in a dispute over parental rights and visitation, it's important that all efforts are made by both sides towards reaching an agreement that is beneficial for everyone involved- most importantly for any children who might be affected by these decisions. It's essential that parents remember they have a responsibility not only towards themselves but also towards their children when making tough decisions about parenting arrangements so they can make sure every party involved is kept safe while allowing each parent time with their kid(s).
