Hello Mr./Mrs. @Jeddy,
thanks for sharing your question with the Wefugees community.
I can understand that you fear about your private information, which you think the lawyer may share with the authorities. However, you don't need to be scared about it, because the lawyers in Germany are obligated to keep the secrecy of information about their clients. If they breach this obligation, they can be punished for this or even lose their permission to work as a lawyer. Nevertheless, only in some exceptional cases, for example, wenn the lawyers can prevent with their information a treason, murder, manslaughter or counterfeiting of money, they must inform the relevant authority or the sufferer about it.
Considering the above points, in your case, the private information about your asylum must be save with the lawyer. The lawyers are there to defend your case and are on your side. Wenn you go to a lawyer or contact her/him, you can also ask her/him about it. I am sure they will explain it for you in details and they will even give you some papers in which everything about the secrecy of your information with them is explained. Without your permission, they can not share your private information with any authority.
