Yes, unless the child is adopted.
That is up to the interpretation of the courts and why the arrears exist.
Yes. If the custodial parent is breaking the court orders the judge can give custody to the non custodial parent if he/she is fit.
Yes, but he should file for SSD and a modification. see links below
If there is a current order for support the custodial parent would need to file suit to have the amount increased regardless of the circumstances of the non custodial parent.
They can't simply "give the child to you." You need to return to the court and have the custody order modified so you'll have legal custody. It will go easier if the current custodial parent consents to the modification. At that time the current support order should be terminated and you can request child support if you wish.
There can be legitimate reasons for withholding a visitation. Those reasons must be explained by testimony in a court hearing if the non-custodial parent files a motion for contempt against the custodial parent. The custodial parent should be well prepared with dates and times and reasons for withholding the visit along with witnesses if possible and should be reporting the circumstances to their attorney.Possible reasons include:A court order to that effect.Suspicion that the child is being abused or neglected. This must be followed up as soon as possible with a temporary court order until the situation can be fully evaluated by the court.The non-custodial parent appears to be under the influence of alcohol or drugs when they arrive to pick the child up.The child is very sick.The non-custodial parent arrives at an unscheduled time.The non-custodial parent does not appear in person to take the child. If they send a substitute without the prior approval of the custodial parent the custodial parent could refuse to allow the pick up.
I'm not sure what state you are in, but in Utah a non custodial parent may NOT claim the child if they are not current on child support. You need to check your individual state. I'm thinking the custodial parent could claim the child if the non custodial parent isn't able to. I don't see why they would allow the exemption to go to waste. It's not like your taking it away from him, just using it because NCP can't.
for what?
Yes! Why would you want to keep that from the "custodial parent" anyway?
Unless visitation rights for the non-custodial parent were allowed in the divorce paperwork, the custodial parent is completely within their rights to deny the non-custodial parent visitation....however, the non-custodial parent may sue for visitation rights.
No. The non-custodial parent needs to have the visitation rights enforced by the court if necessary.
