What should the defendant's children do if they want to defend the defendant?

The children of the defendant are close relatives of the defendant in criminal law, and are actually more qualified as defenders than lawyers (because close relatives can even hire lawyers as defenders without the consent of the defendant). So, all you have to do is prove your relationship with the defendant.

But the criminal procedure is relatively strict. It is suggested that even if you act as a defender, you should consult a local lawyer first.

The following provisions of the Criminal Procedure Law can be used for reference:

Article 32 A criminal suspect or defendant may, in addition to exercising the right of defense, entrust one or two persons as defenders. The following persons may be entrusted as defenders:

(1) lawyers;

(2) A person recommended by a people's organization or the unit to which the criminal suspect or defendant belongs;

(3) Guardians, relatives and friends of criminal suspects and defendants.

A person who has been sentenced to punishment according to law or deprived of or restricted personal freedom shall not act as a defender.

Article 40 The victims of public prosecution cases, their legal representatives or close relatives, and the parties involved in incidental civil actions and their legal representatives shall have the right to entrust agents ad litem from the date when the case is transferred for examination and prosecution. The private prosecutor and his legal representative in a case of private prosecution, and the parties to an incidental civil action and their legal representatives have the right to entrust an agent ad litem at any time.

The people's procuratorate shall, within three days from the date of receipt of the case materials transferred for examination and prosecution, inform the victims and their legal representatives or their close relatives, the parties involved in incidental civil litigation and their legal representatives that they have the right to entrust agents ad litem. The people's court shall, within three days from the date of accepting a case of private prosecution, inform the private prosecutor and his legal representative, the parties to an incidental civil action and his legal representative that they have the right to entrust an agent ad litem.
