Be aware that an oral agreement can still be enforceable, though you must show evidence to support your claim. Check if the statute of limitations in California has any impact on your case, as missing deadlines can affect your options.

Throughout the process, gather as much clear documentation as possible to strengthen your case if you need to present it in court.
