Legal analysis: the starting salary of lawyers in economically underdeveloped areas is generally in 500 yuan-1000 yuan; In economically developed areas, such as Beijing, Shanghai, Guangzhou and other big cities, lawyer's fees are relatively high. For example, in Beijing, some lawyers can take over a divorce case for two or three thousand yuan; Some lawyers can start at 10 thousand. Lawyer fees vary according to the amount of the subject matter of the case. At present, the average legal fee for marriage litigation in Beijing is about 5,000 yuan. Therefore, if the lawyer's fee is within this range, I think it should be considered normal. As for which lawyer to represent, it depends on the lawyer's background, work experience and professional level, and the parties need to contact the lawyer themselves and then determine according to other information.
