Have long had problems with 6 yr olds visitation with his father. Advice?

Since I divorced my childs father 3 yrs ago I have had concerns about his visitations. He does not abide by the agreement and he is irresponsible. I worry every 2nd and 4th weekend of the month.
Examples include:
He is an admitted drug addict/alcoholic (although he now claims sobriety- I don't believe)
He is a felon with a decent size record. Has no license, no car. No phone.
Visitations are suppose to be supervised by the paternal grandmother and she is suppose to be there at all times. However she is not. She is very rude to me and even hung up on me when I tried to check up on my son this past weekend, would not answer my calls.
He is over 6,000 behind on child support
He left me with thousands of dollars in bills which he agreed to pay half of in our divorce agreement, he has paid zero cents.
He has contributed nothing towards medical, school anything for the son. yet bought him 2 psps and a dirt bike. Took him to disney world last christmas without my consent, via train and plane (no grandmother supervision. We live in NC, I didn't hear from them for 2 days and he called me from FL.
They do not put my son in a car seat
He always comes back reaking of cigarette smoke and coughing from it.

Here's the thing. I'm thinking about just not letting them take him next time. Could I be in trouble with the law for not allowing visitation. Or will they have to take me to court first. I am married now and my husband is in the USCG. I don't know but I might be eligible for legal aid if they take me to court. I'm sure I will win but I do not want to go through that, plus I am 5 months pregnant.
I know there is no abuse or neglect during the visitations. However, his wrecklessness and irresponsibility worry me. On top of me not knowing where my son is going when he goes for visitation (he takes him to where he lives 3 hrs away)
Any advice? Everyone says I just shouldn't let them take him anymore but I don't want to get in trouble

I am happy that I have my son and I disagree- I don't think he has the rights I have as the parent. He hasn't been one, honey.

You need to contact an attorney and file for contempt.

Make a list of the reasons:

Leaving State without permission
Supervised visitation not taking place
Driving the child without a car seat
Support Arrears


He will have to answer to a Judge as to
why he has violated the court order.

They can put him in jail for being behind on support.
He would have to pay a child support bond and a regular bond.
They can also suspend his license.

Best wishes

Yes, you can get in trouble if you don't allow him to go.
However, just tell your lawyer, and let him/her do all the work. Especially the 6000 you say he owes in back payment. That right there could put him behind bars. Dead beat dads, the courts don't tolerate.

you better believe you will get into trouble, perhaps even go to jail.
hate to tell ya, but you were the one that picked him in the first place. he is now the kids father and has every bit as much right to be with him as you do!!!
if he doesn't pay support, take him to court.

should have used protection if you didn't want to be in the place your in now.

You are correct that you cannot deny visitation to the horrible parents of the world. However, look at your papers again. Does it specify where the supervised visitation is supposed to take place? Does it specify the paternal grandmother or just supervised visitation? Look closely at this. If there is not specifics, it would be totally within your right to have him have supervised visitation closer to you. Or you could show up at grandma's house with a copy of the court order and call the cops. Then he is not abiding by the order and he would have to bring your son back to you or be in contempt of the court. When the judge signed off on those papers they became law. To change anything you will have to take him back to court. And I don't know if the USCG is the same, but the military is very very funny about their own not taking care of their families. You could call his supervising officer and say something about the 6k and they could make sure that you get the money. Do some poking around and then spring it all on his ***. You have done your part the whole time so he won't have anything to throw at you. I will say a little prayer for your baby and Good luck to you.
