@Melonlity -- and, quite often, those appointments are for both criminal and civil matters. Getting involved in representing juveniles isn't a bad way to get some steady work when you're building a practice, but be careful if you take that approach. In some jurisdictions, you will serve as the attorney of record for a juvenile until he or she becomes an adult. That can be a problem.
Look at it this way. Courts typically don't pay the standard, hourly rate for attorneys when they appoint cases to them. That may be fine in the beginning, but let's say you wind up representing a 13-year-old kid who has a knack for getting into trouble. Getting a reduced fee to represent that kid may be fine at first, but how about four years later when representing the juvenile takes time away from more lucrative cases? Imagine having about 10 juveniles like that and you're looking at a bunch of clients who could effectively interfere with your ability to even take on cases that pay much better.
