Objective: Typically, preliminary negotiations are the basis for concluding important contracts; at this stage, the preliminary stages of the contract are also the principle of the freedom of the state; however, the problem is that, if negotiations are canceled by one of the parties, in spite of the said principle, on the basis of which the negotiation can be terminated It is responsible for this and what effect does it have on this responsibility. Methodology: This paper deals with the comparative study of the subject in French law, the Iranian law and the principles of international agreements and the principles of European law of contracts, that in French law and the principles of the foregoing violation of the obligation of good faith and the commission of the blame is the basis of this responsibility and closed in the legal system of Iran The case and, if any conditions exist, one can use the general principles of civil liability (typing, laxer, pride and fault) in this regard. Results: However, subject to the terms of the negotiated settlement's liability, he or she will be liable for any damages incurred; however, no losses will be incurred and, in the sense of a merely probable interest, arising from the conclusion of the contract, will not be required. Conclusion: finaly, In examining the civil liability aspects of work accidents in mines, we considered the three pillars of damage entry, gravity and causality relation in terms of economic analysis. The economic analysis of rights affects the meaning of loss in civil responsibility and gives it a more in-depth look. This shift is the result of a shift in economic analysis to the goal of civil responsibility and attention to deterrence.
