Legal Question in Criminal Law in California

Ordinarily, you get whatever attorney is assigned to you from the Public Defender's office. If you have some sort of substantial conflict with the one you have, you can ask for a Marsden hearing. There, you can air your grievance with the judge in a confidential setting (meaning the DA can't listen to your complaints and discussions about the case). If the judge finds that your attorney needs to be replaced, they can make that call.

Discuss your issues with your public defender FIRST. There may just be some things that need to be discussed.

The judge won't replace your public defender just because you don't "like them."
