It states: “Evidence by witnesses of prior or contemporary agreements of a written document shall not justify provisions that have been added or that run counter to the content of a document.”  However, section 2724 permits such evidence where the legitimacy of the letter is questionable.  In preparation for litigation, I recently thought of this quote. There is a general misunderstanding that you cannot have a contract unless it is written. In general, this is not true; Oral agreements can be binding contracts.* *8 And in the case of Plante v. Fullerton, Oct. 46, 11, 148 p. 87, we said: for example, employers, workers and independent contractors may find it invaluable to document the terms of their agreements in a contract of employment or a contract of service. While an oral agreement can be legally enforceable, it can be difficult to prove it in court. If your oral consent is unenforceable for any reason, in particular if it is contrary to fraud law, this does not necessarily mean that you do not have recourse. While you will not be able to enforce the specific terms of your initial agreement, you may be able to bring a so-called “fair” remedy to the courts. . .
