In the event the above link does not work, go to
click on “Public Services” (left side of page);
in the list you’ll see “file a complaint against an attorney” (click on it).
You’ll get info - also to the left, you’ll see a link for the “complaint form” and FAQs.

{I may be back with more info in a few minutes.]

OK, this is what I was going to come back with:

Today, most lawyers (I believe) are members of the American Bar Association. I checked their website. They refer complaints to the state - and to the address, basically, that I already gave you. However, here is some info — names, fax numbers, etc., that might get you started:

Directory of Lawyer Disciplinary Agencies (webpage):

It gives these two addresses with phone/faxes:

State Bar of California
1149 South Hill Street, 10th Floor
Los Angeles, CA 90015-2299
213/765-1468
FAX: 213/765-1029
Website:

State Bar of California
180 Howard Street, 6th Floor
San Francisco, CA 94105-1639
415/538-2063
FAX: 415/538-2214

Write one or both (make some noise).

Good luck.
