Can I hire lawyers from two law firms in the criminal investigation stage?

Yes, you can.

Article 33 of the Criminal Procedure Law: 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. The defendant has the right to entrust a defender at any time.

Article 37 If a defense lawyer requests to meet with a criminal suspect or defendant in custody with a lawyer's practice license, a certificate from a law firm, a power of attorney or a letter of legal aid, the detention center shall arrange the meeting in time, which shall not exceed 48 hours at the latest.

In cases of crimes endangering national security, terrorist activities and particularly serious bribery crimes, defense lawyers should obtain permission from the investigation organ when meeting with the criminal suspect in custody during the investigation. The investigation organ shall notify the detention center of the above situation in advance.

When a defense lawyer meets a criminal suspect or defendant in custody, he can understand the case and provide legal advice. From the date when the case is transferred for examination and prosecution, the relevant evidence may be verified with the criminal suspect or defendant. Defense lawyers are not monitored when meeting with criminal suspects and defendants.
