The unequal agreement itself is invalid and does not need to be noted. An unequal clause in a contract may be revoked by a people's court or an arbitration institution, or it may be directly asserted that the unequal clause is invalid. Whether the civil act is unequal should be judged by the situation when the act is established. The rights and obligations of both parties in an unequal contract are often very unequal, the economic interests are unbalanced, and the principle of fairness and rationality is violated.
