Here, you've posted about what happens if the the noncustodial parent was to not follow the court order to the letter regarding child support (as you said - JAIL). Here's what happens when the custodial parent denies visitation - NOTHING!!!!!!!!!!!!!!!!!!!! They get a little lecture in court, and are free to continue denying visitation time and again!
Judges just sound like broken records saying "don't do that again" over and over.
I agree with the punishment given to noncustodial parents who don't pay, BUT I think that there should be equal punishment for the custodial parent who denies court ordered visitation for their child with the other parent. Why is the punishment for non-payment so harsh in comparison to denial of visitation? Maybe, if custodial parents started losing the children they're denying visitation with, that would be just, fair and equal to the punishment given deadbeats who don't pay. CPs who deny visitation (except in situations where the child is being abused) are deadbeats as well, and should be punished accordingly for denying their children the relationship with their other parent. They aren't looking at the child as their child...they're looking at the child as their possession, and if that isn't abuse/neglect of the child, I don't know what is.
