In the United States, the hourly charging system is the most typical charging method. In America, the so-called hourly rate system is called "hourly rate". In other words, lawyers will charge their clients for every hour or even a part of an hour spent on their cases. In the United States, the risk agency fee is called "emergency fee". Among them, "contingency" means that this kind of reward is accidental and possible, so it is risky. "Fee" means "fee". The so-called "emergency fee" means that the lawyer's remuneration depends on a certain proportion of the total amount paid by the court for the case he represents. In other words, if a client hires a lawyer to file a lawsuit, if he loses the lawsuit, the lawyer will not get any remuneration. However, the client still has to pay the lawyer's related fees, that is, the lawyer's "fees" for handling cases. In the United States, the proportion of lawyer's risk agency fee varies, and the general proportion is one-third. Some lawyers increase or decrease their share of remuneration according to the specific progress of the case. In the United States, the packing fee is called "lawyer's fee". This charging method is very similar to the monthly ticket we use for public transportation. The so-called package fee is a series of fees paid to lawyers. Most of this fee is calculated according to the time-based charging system, and this package fee is also considered as a down payment.
