Ultimately the answer to your question depends exactly on what your daughter was charged with. People often interchange the charges of shoplifting and larceny which would slightly change the answer. For the purposes of this answer, I'm going to assume that she was charged with shoplifting - concealment of goods.
Shoplifting - concealment of goods is a class 3 misdemeanor in North Carolina which, if tried as an adult, exposes her to a maximum punishment of the 20 days in the county jail. However, if she was under the age of 16 at the time of the offense, she will be treated as a juvenile and referred to juvenile court.
If your daughter has never been in any trouble before, the juvenile court counselor may attempt to divert her case in order to keep her out of juvenile court. Often times this involves developing a plan or contract with the juvenile, monitoring the juvenile or a referral of services by the court counselor. If there is non-compliance by you or your daughter, the court counselor may seek to file a petition in the case.
The alternative is that the court counselor goes straight into filing a petition against your daughter. Once filed, your daughter has the right to an attorney and one will be appointed by the court if you cannot afford one (however, the costs of such attorney may have to be repaid). The juvenile is then afforded an adjudication hearing at which point she may admit responsibility to the crime (which is similar to pleaing guilty in adult court) or she may deny responsibility and ask for a trial. Please note that the burden in juvenile court is less than the regular criminal court of "beyond a reasonable doubt". In juvenile court the burden is "clear and convincing evidence".
If the judge ultimately finds that the juvenile is responsible for the crime, the court then moves to the disposition phase. Given the offense and what you've told me about your daughter's lack of a prior record, she would likely be classified as a Level 1 offender. Punishments for a Level 1 offender can range from probation, community service, curfew, denial of drivers' license, etc.
Ultimately, your daughter will have the right to an attorney that has a better feeling for your local court counselors and district attorney's office. I encourage you to contact one and speak to them about your daughter's case.
