| Actually，in places where there is a civil custom , the civil subjects usually function or malfunction in accordance with the civil custom, and would overlook the existence of the civil law, or maybe they even didn't know whether there is a civil law . In the process of applying the civil custom during the suit, the civil custom is often taken as “the object of proof” at first, and then in accordance with the principle of “He who is affirming must prove”, the party who claims that the civil custom is to exist should provide evidence in accordance with the law. At the same time, the court may, by exercising its functional authorities, conduct investigation of the party’s claim and the evidence. |
