Do you entrust a lawyer to get a marriage certificate in a car accident?

Whether the lawyer entrusted by the car accident brings a marriage certificate depends on whether the car accident is a criminal case or a civil case. Lawyers entrusted by criminal cases need marriage certificates, and civil cases can bring ID cards. According to the provisions of the Criminal Procedure Law, only close relatives can entrust lawyers. Spouses, parents and children are legal close relatives and need to bring documents to prove kinship. Family members of civil cases entrust lawyers to defend and hold identity cards.
