After successful passing the qualification exam a candidate should take the oath of advocate. From the moment of taking the oath, he becomes an advocate and a member of the advocate's chamber of the relevant federal subject of Russia. Advocate's chamber sends relevant information to the territorial subdivision of the Ministry of Justice of the Russian Federation, which includes the new advocate in the register of advocates of the relevant federal subject of Russia and issues to him an advocate's certificate, which is the only official document confirming the status of an advocate, on the basis of this information. The status of an advocate is granted for an indefinite period and is not limited by any age. There is only 1 advocate's chamber in each federal subject of Russia. Each advocate can be the member of only 1 advocate's chamber and can be listed in the register of advocates of the relevant federal subject of Russia only. In case of relocation to another region, the advocate ceases to be a member of the advocate's chamber and should be excluded from register of advocates at the old place of residence (advocate's certificate should be returned to the subdivision of the Ministry of Justice of the Russian Federation, which issued it), and after that he becomes a member of the advocate's chamber and is included in the register of advocates at the new place of residence (where he receive new advocate's certificate) without any exams. Each advocate can carry out his professional activity throughout Russia, regardless of membership in particular regional advocate's chamber and regardless of particular regional register where he is listed in. Advocates carry out their professional activity individually (advocate's cabinet) or as the member of advocate's juridical person (collegium of advocates, advocate's bureau). Advocate can open own cabinet after at least 3 years legal practice in collegium or bureau. An advocate, who has opened own cabinet, can not be the member of any advocate's juridical person, and an advocate, who is the member of one advocate's juridical person, can not be the member of any other advocate's juridical person. Advocate is obliged to report to advocate's chamber any changes in his membership in a collegium or a bureau and, equally, opening and closing a cabinet.
