Butte County Superior Court at 1 Court Street, Oroville, California.

Calling there is a waste of your time to get someone who knows anything. They'll put you on hold a long time to get transferred to the right place, if you're lucky.
The public files are just that, "public" and available in every other CA county I've checked. So, why now is Butte county so hard to ask questions, access public records, or even records of cases you are a part of?
There's NEVER enough room for people to sit in the courtrooms, especially in Chico. Get there really early for a chance to get a seat.
The Chico service desk is a nightmare unless you're only there to paying a ticket or 1-2 other departments. Long waits for small claims, family law, or probate. If you fall into the any other option, you may wait hours for help. Monday mornings and early afternoons seem to be the least busy. Do everything you can to avoid being there on Thursday afternoons!

I am very respectful and courteous with the staff and I always get treated the same in return. Just make sure you don't have a lighter or a pocket knife on you when entering. They're pretty cool about it but it is against the law
