Your friend can find the guardian of the student who worked together to bear the compensation. As for the distribution of responsibilities, we can negotiate on our own. Of course, this kind of thing is not negotiable. If negotiation fails, the guardian of the hands-on student can be brought to court, and the school can also be brought to court. But don't expect too much from the school's responsibility distribution, because the school only bears the supplementary compensation responsibility and bears it within the scope of its fault. As long as the school proves that it is not at fault, it is not responsible. For example, or the location is hidden? Wait, there are many reasons why the school can shirk, and the specific determination is after the judge knows the specific case.
Finally, the amount of compensation awarded by the court will only be within the scope of the plaintiff's request, that is to say, how much he asks, the less the better, and never exceed his request. Even if his requirements are obviously low, the court will not take the initiative to give him extra points. This is a matter of principle.
I suggest you take legal proceedings. Although the judgment compensation will be higher than 50 thousand yuan, there is still a mediation process before the judgment. You can use this mediation process to achieve a legal settlement, or you can bring in the school and the guardians of the hands-on students together, so that the compensation you bear will definitely be less than the 50,000 yuan now settled, and you can also get a mediation book or a judgment, but you must make a clear settlement in legal documents, otherwise I will ask you if there is any situation.
