No. Notarization does nothing to validate the truth of a document or make a document legally binding, it merely is a method by which one can attest that the signatories on the document are whom they claim to be.
The above statement does not create an attorney-client relationship and the submitting party should not consider the responding their attorney.
I agree with Attorney Thomas. Notarizing the document does not affect its validity. It merely takes away a potential argument that one of the parties did not sign the document.

Information provided on this site should not be used as a substitute for competent legal advice from a licensed attorney that practices in your state. The law changes frequently and varies from state to state. If I refer to your state's laws, you should not rely on what I say; I just did a quick Internet search and found something that looked relevant that I hoped you would find helpful. You should verify and confirm any information provided with an attorney licensed in your state.
To be legal, a contract requires an offer, an acceptance and consideration ($$$ or a promise to act or not act) between two or more people (including entities) who are competent. Unless it involves real property or will be performed for a period of more than a year, an oral contract is as valid as a written contract, however an oral contract is hard to prove (he said/she said). As noted by my colleagues, it nearly needs to be signed.
There is an old saying: "He who represents himself has a fool for a client." I did not handle my own divorce. I suggest you not write your own contract as there will be issues you will overlook.
The foregoing is not intended to be legal advice upon which you may rely as I have not been retained for this purpose.
