California Juvenile Crime Lawyer

Juveniles, or children under the age of 18, will enter the juvenile criminal justice system when arrested or charged with a crime. While the juvenile system is different, the penalties can still be severe and damaging to the record of a young person. When representing juveniles, our priority is to position the minor for minimal charges and a reduction of penalties. We also work to keep juveniles in school and through rehabilitation, where necessary.

In every case, our attorney will sit down with a child and their guardians to discuss the specific facts and allegations. We will work with experts where necessary and take every available avenue of defense to secure an optimal resolution for our clients.

We are experienced with juvenile crimes, including:

  • DUI
  • Minor in possession of alcohol
  • Reckless driving
  • Destroying public property
  • Driving with license suspended or revoked
  • Drug crimes — possession, distribution or trafficking in marijuana, meth or cocaine
  • Sex crimes
  • Shoplifting or theft
  • Sealing the record

Post-Conviction Matters

For many adults and juveniles, post-conviction matters may arise. We are experienced in handling criminal legal issues involving probation, expungement and sealing the record for juveniles.
