Legal analysis: Hello, generally speaking, the sooner you entrust a criminal lawyer, the better, because lawyers can get involved in analyzing problems as soon as possible. After the first interrogation by the investigation organ or after compulsory measures are taken, the parties concerned may hire a lawyer to provide legal advice. After the party "has an accident", the family members should find a lawyer as soon as possible, let the lawyer intervene in the case from the public security investigation stage, meet the party as soon as possible, and understand the case.
Legal basis: Article 33 of the Criminal Procedure Law of People's Republic of China (PRC). A criminal suspect has the right to entrust a defender from the day when he is interrogated for the first time by the investigation organ or takes compulsory measures. During the investigation, only lawyers can be entrusted as defenders.
