Legal Question in Criminal Law in California

Re: do i have a warrant?

You generally can't. If you think you might have a warrant for a relatively minor crime and know where it would have come from, you can call the local court and ask. They might very well agree to tell you. But if the crime is a major one the authorities will not let you find out ahead of time lest you go into hiding and make it harder for them to catch you -- which is probably what you intend to do if you learn that there actually is a warrant for your arrest.
