I have a client that has terminated me and is trying to get out of paying my final bill because she is trying to invalidate my contract. I used an AIA cost plus a fee with no guaranteed maximum price.

Your question is a bit ambiguous regarding which notices you mean, exactly - i.e. if you're looking for 1) required contractual provisions, or 2) notices regarding mechanics lien or other nonpayment protection.
Regarding 1, above, there are certain things that must be included - and this can change depending on the nature of the project. ALL California construction contracts must include the contractor's license number. Other than that, however, the requirements change by project type.
If the work is NOT a "home improvement contract" the following paragraph must be included on the contract in at least 10-point font.
"Contractors are required by law to be licensed and regulated by the Contractors’ State License Board which has jurisdiction to investigate complaints against contractors if a complaint regarding a patent act or omission is filed within four years of the date of the alleged violation. A complaint regarding a latent act or omission pertaining to structural defects must be filed within 10 years of the date of the alleged violation. Any questions concerning a contractor may be referred to the Registrar, Contractors’ State License Board, P.O. Box 26000, Sacramento, CA 95826."
If the project is a home improvement project, however, there are many, many specific requirements regarding the contract. These requirements are set forth by Business and Professions Code section 7159. This section details extensive requirements in type-size, language, headings, and more. There is a lot of information and there are a lot of requirements, so it is worth getting familiar with that section if you work on residential property.
