What should a parent do when a lawyer meets his son for the first time?

No explanation is needed

After the first lawyer meeting, under normal circumstances, the lawyer will convey some family matters and, on the premise of practicing in accordance with the law, will tell the family members of the client the general situation of the charges and other facts of the case.

After the family members entrust a lawyer, they must promptly implement the matters explained by the detainees, such as retrieving the clothes and property temporarily detained at the police station, and promptly repaying credit cards, housing loans, car loans, etc.
