Whether you accept a case or not, you have to pay a deposit to the law firm to practice law. Avoid practicing random practices to bring risks to the law firm. The amount of deposit charged varies from law firm to law firm. It is said that the fee a lawyer charges for accepting a case is called attorney's fee. It is the labor remuneration earned by the lawyer for his professional and technical work, and is not called commission. When it comes to securities and futures trading, what the trading platform provided by the securities firm charges is called a commission. To put it bluntly, your commission is an "intermediary fee." According to your thinking logic, the security deposit you mentioned must not be the same concept as the security deposit collected by the lawyer. The margin for securities and futures trading is the principal used to increase leverage. The deposit collected by the law firm is used to promise to practice law and compliance.
