How long can they keep a 15 year old I'm juvenile for fighting ?

Need a little more information to answer what you're trying to ask. Many attorneys devote a part of their practice to representing juveniles charged with a crime. Consider contacting such an attorney so you can give them all the details and they can help get you through this.

Based on the way the questioned is phrased, you are assuming that you would be placed into custody for fighting. I'll break it down this way: 1. You can be placed into "secured custody" which is the term for juvenile court for essentially being under arrest before trial. If that were to take place, 1) it probably already happened, and 2) must be reviewed within 24 hours or as soon as possible (for example Monday morning after a weekend). If secured custody is continued, it must be reviewed every 7 days until ended, or the case is disposed. It is unlikely that secured custody is going to be granted to for a fight. Plus you are emailing this forum, indicating you are not in custody. 2. Fighting generally falls into either a charge of simply affray - which is literally means fighting. The other option is an assault charge of some kind - simple assault, Assault inflicting serious injury. All of these charges are misdemeanors, although there is some variation between how they are treated in juvenile court. 3. If you are charged in juvenile court - the charging paperwork is called a petition. It is not a warrant, or a citation. When you are served, or given the paperwork, you are not taken to jail. Again, that is done only if there is a belief that you are a danger to the public. You are given the information, and told to go to court. It can take up to 60 days, approximately 2 months, for a petition to be filed. 4. If a petition is filed for either simple affray or simple assault, that is a Class 2 misdemeanor. Based on your question, it is unlikely you have been involved in the juvenile system, or you would have some idea how long you could be held for a juvenile petition. Juvenile charges are classified into 3 categories - minor, serious, and violent. A simple affray or simple assault are minor charges, as are all Class 1-3 misdemeanors. If by chance you are charged with a more serious assault, such as Assault inflicting Serious Injury, or Assault with a Deadly Weapon, that would be an A1 misdemeanor, which falls into the Serious Category, which covers all charges from A1 misdemeanor to Class F felony. On the very unlikely chance that you are charged with some major felony, such as Assault with a Deadly Weapon Inflicting Serious Injury (a Class E Felony), that would be a Violent Offense (Class A-E Felony). 5. You will need to meet with the Dept. of Juvenile Justice for them to determine your appropriate level. A Minor Offense, with no criminal history, will be a level 1 - with a maximum of up to 5 individual 24 hour periods of incarceration at the Youth Detention Center, although with a number of other conditions. A serious offense raises the possibility of a Level 2 punishment - with a maximum of up to 14 individual 24 hour periods of incarceration at the Youth Detention Center. These punishments can also include transfer to a wilderness camp, and other removal from your home. All of these situations are unlikely as long as you follow conditions of your probation, which will be explained to you. 6. After writing all of the above, as a juvenile you are ABSOLUTELY ENTITLED to an attorney. One WILL be appointed to you. You do not have to ask for one. You are presumed to be "indigent" or in other words, too poor to afford to hire a lawyer. That lawyer will be able to determine what level punishment you face, he/she will know what the likely punishment will be for your charges, and you can ask him/her any questions you may have. Do so. They are the best resource for you.
