Yes, annual filing is required within the first quarter of each year. According to Article 17 of the "Measures for the Administration of Legal Professional Qualification Certificates", judicial administrative agencies implement an annual filing system for certificate holders who have not yet engaged in the legal profession.

Certificate holders who have not yet engaged in the legal profession should bring a copy of the legal professional qualification certificate to the local (city) Justice Bureau for annual filing within the first quarter of each year. The prefectural (municipal) judicial bureau shall report the annual filing status to the provincial (district, municipal) judicial department (bureau).

The legal professional qualification certificates are all the same. They are divided into two copies. The original is a piece of paper. There is an annual inspection column at the back of the copy. Those who do not engage in legal work after obtaining the certificate must go to the local judicial bureau for filing every year. The issuing unit is the Ministry of Justice of the People's Republic of China and the Ministry of Justice, signed by the minister.

As long as the qualification certificate does not change, annual filing is required at the place where the certificate is applied for every year. You only need to bring a copy of the certificate when filing.
