The law pays attention to jurisprudence and facts, and the court makes a conclusion based on whether there is substantial damage or whether it violates laws and regulations. Therefore, it is impossible to determine whether the agreement is legal only by signing. Legal litigation is a complicated process, even if it is legal, it may not win the lawsuit. And even if it is illegal, the lawsuit may not be lost.
Therefore, it is difficult to tell you clearly whether to win or lose in future lawsuits. It depends on what the subject matter of your lawsuit is and the facts involved in it.
I have experienced five or six lawsuits in futures, some simple and some complicated, some lost and some won, some lost and some won and some lost. In short, no one can guarantee winning or losing until the court decides.
