California. I sued my landlord for keeping all of my deposit in small claims court, and he counter sued, lying, saying I didn't give 30 days notice. I said in court I didn't give written notice, but did give verbal notice to which i have witness. The Judge awarded him since I admitted I didnt give written notice.
However, the contract does not specify written. It only says 30 day notice. Can I argue in an appeal that I fullfilled this, or does "notice" necessitate written legally?
