My question involves criminal law for the state of: Utah
I am 16 years old and I was recently caught stealing air refresheners from a 7 Eleven. I wasnt arrested because the officers talked to my dad on the phone and they agreed to let me drive myself home since my parents were at a soccer game and couldn't come get me. It's been about a week now and I have a court date set for December 20. This is the first time I've ever been convicted of shoplifting, and the only other trouble I've had with the police was a mild traffic ticket. I'm a good kid, i get good grades, and i attend school on a regular basis. I've never been in any trouble like this before, and this is my first time ever shoplifting.
I haven't received a civil fine in the mail yet, so when should i be expecting that? What should i expect when i go to court? Should i call the courthouse now and ask them about diversion programs, or should i wait untill the court date and ask the judge about that? If i do take part in a diversion program, what should i expect, and will that guarantee that this will be taken off my criminal record? Should i plea guilty, not guilty, or no contest? I can't afford a lawyer, so should i get a public defender instead, and if so, do public defenders cost any money? I'm very confused and have a lot of questions, so any feedback would be great.
