The study on the pre-contract in author’s contract law is about the period before the author’s contract itself; the pre-contracts can punctuated that period. This study is about the junction, during the pre-contract period, between the system of common law and the author’s contract law rules under which the contract will be written. It appears that the pre-contract period is completely subjected to the common law rules even though the author’s contract law has an indirect influence on the pre-contract, especially concerning the importance of certain duties. Thus, the pre-contract, which appears before the author’s contract, is subjected to the common law. However, the period of the pre-contract does not ignore the author’s contract law. It gives a legal framework to pre-contracts which can be concluded by the author. Pre-contracts allow contracts’ law rules to infiltrate the pre-contract period.
