I am a self represented defendant in a small claims case. I cannot afford an attorney. With the robust capabilities, and plenty of time on my hands, I can plow through the case law and ca civil codes, but I can't readily find and fill out forms. PDFfiller has the forms I need and does a credible job of filling them out.
