How can I get visitation orders enforced, driving child with suspended license prohibited and jurisdiction moved from NY to MS?

Officer found container that had no measurable amount of marijuana, just dust. Charged with possession. How can they do this?

Officers typically follow the "charge them all and let the courts figure it out" model. A good defense attorney will do you wonders.

My son was given a ticket for Minor in Possession in Destin FL. He has a court date but was told to send in $200 for fine.

You'd need to ask a FL lawyer that question. However if you just send in the fine, it will be counted as a conviction.

No. MS does recognize driving school to keep tickets off your record (for future purposes).

Any one of the first three guys answering your question would be a good choice.

Sounds like it's time to go back to court and modify the decree.

If a mother leaves her child with the father how long can you get her for abandonment ?She isn't even calling the child

There may be other issues that can get you what you want without going the "abandoned" route. From what you've said, sounds like you shouldn't...

I'm wanting to gain full custody of my 12 year old son.

Sounds like you got a pretty good chance of getting custody. You'll just need to get a local lawyer and file for modification of custody.
