No, notarization is just a way to guaranty the genuineness of signatures, so someone can't deny that they signed something. It doesn't affect the contents of the document. Even oral contracts are "legal" and enforceable on CA.
Your contract needs to have all the material terms to be enforceable, and sometimes non-lawyers don't know what those are. Pleas see my Legal Guide linked below. You should see a lawyer to review (and probably improve) your contract before you sign it.

This is a common misconception. A notarization is not necessary to make most contracts binding. Although, it does offer a very useful feature: it makes it VERY difficult for the signatory to claim that the signature is a fraud. In the world of "personal" contracts (a term I use for inter-family/friend contracts) this is sometimes a life saver in my experience.
Also, as mentioned previously depending on the nature of the contract you have to make sure certain essential elements are present or the Court (If one has been tasked with enforcing the agreement) will not enforce the agreement. These are some that are essential in almost any contract: 1) the date; 2) the actual nature of the transaction (e.g., if it's the sale of a car, then the car and the price should be specified, among other things; if it's a loan, the loan amount and repayment terms, among other things should be specified.); 3) the names of the signatories and a clear indication that they accepted the deal; and 4) consideration (this is a legal term that simply means that something of value was exchanged for the deal to be consummated.
My fellow professionals are correct. A contract does not have to be notarized to be legal. Documents do have to be notarized to be recorded. Your contract will not be inadmissible for lack of notarization.
