In criminal cases, I only hired a lawyer for one stage. The first stage is over, and the second stage is not hired. What procedures should I go through?

If the entrustment contract only has the first stage, it is unnecessary. The first stage is to provide legal aid in the investigation stage, including providing legal advice, acting as an agent to appeal and accuse, and applying for bail pending trial. In the second stage, the public security organ will transfer the case to the procuratorate for examination and prosecution, and the lawyer will mainly go to the procuratorate to read the papers and check the transcripts and evidence materials. The third stage is the court trial stage, and the lawyer's duty is to defend and put forward innocent or lightest opinions. You can delegate only one stage or all stages.
